How does Bar’s Leaks Engine Repair work?
Engine Repair contains a combination of the best performance additives to repair the most common oil-related problems. Engine Repair restores lost compression and power, reduces noise and oil consumption, while improving the performance of worn cylinders, rings, bearings, and seals.
Will Bar’s Leaks Engine Repair clog my oil filter?
No, Bar’s Leaks Engine Repair does not contain any sticky substances that would clog or damage your oil filter. It works chemically to stop leaks in gaskets and seals.
Will Bar’s Leaks Engine Repair work in synthetic oil?
Yes, Bar’s Leaks Engine Repair is compatible with ALL types of engine oils, including petroleum, synthetic and high-mileage formulas.
Isn’t Engine Oil Enough?
Engine oils are generally used to reduce friction between moving parts. In addition to lubricating, motor oil must cool, provide corrosion protection and is a method of removing contaminants. As lubricants degrade, their properties change, leading to increased friction and wear. Over time the natural wear that occurs inside the engine causes reduced oil pressure, loss of compression (power loss), lower fuel mileage, oil consumption (leaks & smoking) and noise (knocking & ticking).
Can I add to existing oil?
Yes, remove engine dipstick and check oil level. If oil is low, remove oil cap and install entire contents of the two chamber bottle. Do NOT overfill. Top off with manufacturers recommended engine oil as needed. Reinstall dipstick and oil cap. Drive/idle engine for 10-15 minutes.
If I install more than the recommend amount, will it work faster or better?
No, we have formulated our product to work best at the suggested dosage amount.
What are the dosage recommendations?
One 15.5 oz bottle of Bar’s Leaks Engine Repair, part number 1000, treats 4 to 6 quarts of oil.
If first application does not completely stop my leak, may I add another bottle?
Yes, in engines with seriously damaged components, a second treatment may be required. In this case, it is suggested that the oil and filter be changed, and a second application of Engine Repair be added.
How long does it take to start working?
Bar’s Leaks Engine Repair starts working the minute you install and start driving the vehicle. You will usually see results in about 250 miles or three (3) days of driving.
How does it work?
Smoking is usually caused by gaps in internal engine parts resulting from excess wear. Smoke Away with Stop Leak contains viscosity improvers that thicken the oil film filling these gaps. Smoke Away cushions and coats engine parts helping reduce wear and quiet noisy lifters.
Will Bar’s Leaks Smoke Away with Stop Leak clog my oil filter?
No. Unlike our cooling system product, Bar’s Leaks Smoke Away has no particles to plug the leak, it works chemically to stop leaks in gaskets and seals.
Will Bar’s Leaks Smoke Away w/ Stop Leak work in synthetic oil?
Yes, Bar’s Leaks Smoke Away is compatible with all petroleum based oils, including synthetics.
If first application does not completely stop leak, may I add another bottle?
Yes, you can install a second application for hard to stop leaks. If your leak still persists after a second application, then mechanical attention may be required.
If I install more than the required amount, will it work faster or better?
No, we have formulated our product to work best at the suggested dosage amount.
How long does it take to start working?
Bar’s Leaks Smoke Away starts working the minute you install and start driving the vehicle. You will usually see results in about 100 miles or two (2) days of driving.
What are the dosage recommendations?
1 bottle treats 4 to 6 quarts of oil.
FREQUENTLY ASKED QUESTIONS BAR’S LEAKS REAR MAIN SEAL REPAIR P/N 1050
What is a rear main seal?
The simple answer is:
A seal that fits around the rear of the crankshaft to prevent oil leakage.
The more in depth answer is:
A rear main seal, also known as a main seal or rear main bearing seal is located between the engine
and transmission. The crankshaft (the internal engine part that the pistons are connected to) sticks out of the rear of the engine, and the flywheel & transmission bolt to this crankshaft. The engine oil lubricates the crankshaft, pistons and other internal parts of the engine. The rear main seal is inserted into the back of the block and fits snuggly around the rear of the crankshaft and keeps the engine oil from escaping.
What are the symptoms of a rear main seal leak?
Depending on the severity of the leak the first thing you may notice is the oil level going down. The next thing that happens is spotting, where you will find oil spots, located on the driveway or garage. While looking under the vehicle around the area where the engine and transmission connect, you will find oil dripping, or an oil residue with dirt caked on this part of the vehicle, most noticeably under the oil pan and the front of the transmission. In some transmissions, it will actually be the oil leaking out of the front of the transmission. In some manual transmission vehicles, you may also notice some slipping of the clutch, which can occur with a leaking rear main seal.
What causes the rear seal to leak?
The most common cause of rear seal leaks is age and/or high mileage. The seal can also leak due to the vehicle being stored for an extended period of time, or from running the engine low on oil. This causes drying and hardening of the seal leading to shrinking, cracking and tearing of the rear main seal.
What other factors can contribute to a rear main seal leak?
A few things can cause a rear main seal leak to worsen, that are not the fault of the seal itself. If the oil level is two high (filled over the full mark) or the PVC (Positive Crankcase Ventilation) system is not functioning correctly, leaks can occur. The PVC system prevents pressure from building up inside the engine and if it fails, the pressure will cause the oil to leak out. It is a good idea to clean or replace the PCV valve regularly to prevent this problem.
How do you replace a rear main seal?
For most rear wheel drive vehicles the transmission is removed to replace the seal. On front wheel drive vehicles, it is usually easiest to remove the engine to gain access to replacing the seal. Either way, this is an expensive procedure.
What else can be done to stop a leaking rear seal other than replacement?
Bar’s Leaks Rear Main Seal Repair is one of the only products of its kind on the market specifically designed to solve rear seal oil leaking problems. There are special oil additives on the market that are designed to swell the rubber of the rear seal and cause it to expand, thus sealing off the leak. You can also try using thicker weight engine oil, like 50 weight. The thicker oil can fill in the gap between the seal and the crankshaft, and could slow the leak down.
How does Bar’s Leaks Rear Main Seal Repair work?
This product works in two ways to help solve most any seal type leak.
The seal restorer additive restores seal size, flexibility and elasticity lost due to engine heat, age and high mileage.
The seal polymer works by building a polymeric film around the rear main seal and also filling in any groove worn into the crankshaft by the seal.
What types of seals will Bar’s Leaks Rear Main Seal Repair fix?
Because of the Bar’s Leaks 2X Action formula, the product has additives to work on any of the three types of rear main seals, no matter what the material.
What are the different kinds of rear main seals?
(3 basic styles)
ROPE SEAL
Also called a wick seal
TWO PIECE SEAL
Neoprene or called rubber
Silicone
ONE PIECE SEAL
Neoprene or called rubber
NBR or Buna N (Nitrile)
Silicone
PA or Polyacrylate
Viton or Fluoroelastomer
Will Bar’s Leaks rear Main Seal Repair work on other oil leaks?
Yes. Even though it is specially designed to seal rear main leaks, it also works better than a conventional stop leak on all other engine oil leaks. This includes the timing cover seal, O-rings and other seals and gaskets.
Will Bar’s Leaks rear Main Seal Repair clog my oil filter?
No. Unlike our cooling system products, Bar’s Leaks Rear Main Seal Repair has no particles to plug the leak. It contains special polymers and seal conditioners to stop seal leaks.
FREQUENTLY ASKED QUESTIONS BLOCK SEAL HEAD GASKET REPAIR P/N 1100 Click for PDF Version

Bar’s Leaks Head Gasket is only designed to be added to the cooling system. If the product is installed in the gas tank, the tank should be removed and cleaned out by a professional mechanic.
I accidently added the Bar’s Leaks Head Gasket Repair into my engine oil, whatshould I do?
Bar’s Leaks Head Gasket Repair is only designed to be added to the cooling system. If the product is installed in the engine oil and the engine has not been started, in many cases you can remove the valve cover and drain the oil leaving the drain plug off. Then use an engine flush washing out the head keeping special attention to the oil return holes that run down to the oil pan. Clean these out and pour the engine flush down these holes flushing everything into the oil pan and out the drain hole. If the engine has been run, you need to take the vehicle to have a professional mechanic evaluate what can be done to clean the inside of the engine. This might include taking the engine apart to clean all of the parts.
Click for PDF Version Can Bar’s Leaks® Liquid Copper™ Intake & Radiator Stop Leak be installed in existing antifreeze?
Yes, unlike other copper stop leak products, the new Liquid Copper™ One Step sealer contains an antifreeze compatible sodium silicate formula, so draining of the cooling system is not required. It also can be used in water alone however, a second bottle of Liquid Copper™ is recommended to be added to the system once antifreeze is installed.
Will it work in the new extended life antifreeze?
Yes, Liquid Copper™ is compatible with both conventional, green or blue (silicate-based) and extended life red/orange or yellow (OAT/HOAT) antifreeze.
Do I need to drain my cooling system after using Liquid Copper™?
No, this product is designed to be left in the cooling system to protect from future leaks.
How does this type of product work?
It stops leaks by forming a physical plug with organic and synthetic fibers, copper and an ionic modified mineral. The plug forms as the coolant and sealer flow out of the leak. A wetting agent cleans the sides of the hole and prepares the surface for bonding. The first fibers catch on the side of the leak or hole eventually bridging the entire hole. The fibers now act as a sieve trapping more fibers, copper particles and minerals, creating a composite plug. This plug is stabilized or cemented with a liquid glass. The liquid glass hardens with increased temperature and completes the seal.
How long does it take to see results?
Results should be noticeable within 20 to 30 minutes. If the leak is not sealed in 30 minutes of running, a second application may be required or mechanical repair may be needed.
What are the dosage recommendations?
Use 1 (one) bottle for regular size cooling systems, this covers most 4, 6, 8 and 10 cylinder engines. For small cooling systems, such as 4 cylinders with no air conditioning, use ½ (half) of bottle. For larger systems, use 1 (one) bottle for every 6 gallons of cooling system capacity.
Will Liquid Copper™ plug my heater core?
No, Liquid Copper™ will not plug the heater core. Note: If using Bar’s Leaks® to stop heater core leaks, make sure you turn your heater control to HOT. Some vehicles have a valve that controls coolant flow through the core and is only opened in the HOT position.
Can I install Liquid Copper™ in my overflow reservoir?
For best results Liquid Copper™ should not be installed in a regular overflow tank unless it has a screw on pressurized cap. If you do not have access to your radiator, remove top hose where it connects to the top of the radiator and install product in hose. Reattach hose and tighten clamp.
Will this work in both domestic and import cars and trucks?
Yes, Liquid Copper™ will work in all types of water cooled vehicles.

Depending on the power steering problem, results will either be immediate or noticeable within a few days of driving.
If first application does not completely stop the leak, may I add another bottle?
Yes, you can install a second application for hard to stop leaks. We recommend that the power steering fluid be changed and a second application of Bar’s Leaks Power Steering Repair be added.
How much do I install?
The 16 oz Bar’s Leaks Power Steering Repair, part number 1600, is designed for one bottle to be used for every 2 to 3 quarts of power steering fluid, which is the amount most passenger cars and light trucks use.
What are the symptoms of a power steering leak?
Depending on the severity of the leak the first thing you may notice is spotting, where you will find fluid spots located on the driveway or garage floor. While looking under the vehicle around the area where the
rack & pinion or gearbox is located; or the front of the engine where the belt is located, you will find fluid
dripping. The next thing that happens is the steering wheel becomes harder to turn or does not turn
smoothly. This is usually accompanied by a squealing or grinding noise when turning the wheel.
How does Bar’s Leaks Power Steering Repair stop leaks?
This product works in two ways to help solve most any o-ring or seal leaks.
1) The seal restorer additive restores seal size, flexibility and elasticity lost due to heat, age and high
mileage.
2) The seal polymer works by building a polymeric film around the seal or o-ring and also filling in any
grooves worn in the shaft.
What causes power steering leaks?
The most common cause of power steering system leaks is age and/or high mileage. After time, power
steering seals and o-rings tend to dry out and shrink causing leaks. Bar’s Leaks Power Steering Repair works to revitalizes these seals and makes them soft and pliable again.
I have fluid collecting in the rubber bellows at either end of my steering rack, is this normal?
No, the rubber bellows are mainly designed to keep dirt out of the steering rack and only keep in a small amount of thick grease which lubricates the inner tie rod ends. Any signs of fluid in or leaking from the
bellows means a seal inside the rack is leaking. Bar’s Leaks Power Steering Repair is the perfect product
to use for this type of leak.
Will I damage my system if I drive without fluid in my power steering?
Yes, usually damage to your power steering pump will happen within relatively few miles if you continue to drive with little or no fluid in your power steering reservoir.
Will Bar’s Leaks Power Steering Repair help my noisy power steering pump?
Yes, Bar’s Leaks Power Steering Repair contains special friction modifiers to stop bearing, piston and valve noises inside the pump.
Will I have steering if the power steering fails?
Yes, you will always have steering, but the vehicle will be very difficult to steer.
The mechanic said my car has morning sickness. What is this?
Morning sickness is a condition where the vehicle will be hard to steer in the mornings or when cold. In many cases it will feel as if the power steering is not working at all. The cause of this problem is fluid
bypassing worn o-ring seals in the sector shaft (where the shaft from the steering wheel connects to the
rack & pinion) or grooves actually worn into the rack. After driving the vehicle and warming the fluid, the
problem will usually go away, until the next day. Adding Bar’s Leaks Power Steering Repair will renew
these o-rings and the polymer additives will prevent the fluid from bypassing the grooves.
Will Bar’s Leaks Power Steering Repair help smooth my rough steering?
Yes, special lubricity additives will smooth out rough, hard and tight steering.
Will Bar’s Leaks Power Steering Repair harm my steering system?
No, the product is completely safe to use and will not harm any part of the power steering system.
My reservoir is not very low, can I just top of the system with Bar’s Leaks Power
Steering Repair?
If you have a very minor leak, you may not be able to add the entire bottle. The product works great for topping off the power steering fluid level any time you need to add fluid. If using for other problems, you
need to add at least ½ of the bottle into the system.
What is a power steering system?
There Are Two Basic Types of Power Steering Systems
Gearbox (Re-circulating-Ball)
Most Rear-Wheel & 4-Wheel Drive. The gearbox contains a grooved metal shaft called a worm
gear. This gear is threaded into a metal block with ball bearings between the threads to reduce
friction. The block turns a pitman arm which is connected by the tie rods to each front wheel.
Rack & Pinion
Most Front-Wheel & All-Wheel Drive. The steering shaft connects to a pinion gear inside the metal housing. This pinion gear has teeth on it that mesh with the teeth on the rack. This rack is
connected to each front wheel with the tie rod ends.
Steering Components - Power steering systems are combination of mechanical, hydraulic and some
electrical parts.
Mechanical
Many mechanical parts are required to operate a power steering system. Some of the more
important parts are steering shaft, rack & pinion or gearbox and fluid pump.
Hydraulic
The hydraulic system uses a belt-driven fluid pump to create pressure and send this fluid through a high pressure hose to either the rack & pinion or gearbox.
Electrical
Some later model vehicles use electronic sensors to detect the power steering fluid pressure and send information to the vehicle computer.
The common element between all of the power steering components is the fluid. The fluid touches
everything inside the pump, gearbox and rack & pinion. This fluid must lubricate, cool, clean and
pressurize for the system to function. In newer systems, the power steering fluid can easily perform these functions. As the vehicle ages and gains more miles, the fluid alone can’t do the job. Internally, pumps whine, gears have play in them, valves stick, seals leak and the fluid quickly breaks down. When installed, Bar’s Leaks Power Steering Repair helps to stop and prevent these problems and enhances the useful life of your power steering system.
My reservoir is not very low, can I just top of the system with Bar’s Leaks® Power
Steering Fluid With Stop Leak?
If you have a very minor leak, you may not be able to add the entire bottle. The product works great for topping off the power steering fluid level any time you need to add fluid.
