not at all, i have used it for years and had no problems
10 W-40 motor oil can be used in your Subaru, with a minor oil leak. The heavier oil will not hurt your engine and may slow down the leak.
Antifreeze if you get an internal leak in your engine it could ruin the motor
coolant leak between motor and transmission indicates you have a leaky freeze plug in the rear of the engine block
That depends on where the oil leak is, is it in the motor self or is one of the seals leaking?
Any leak will change the way the engine breathes. Any change can change the air/fuel mixture. If it changes enough it can cause damage.
It will most likely fail again. The Lucas just softens and makes the seals expand to help seal the leak. They are usually on temporary.
Yes. Can clog coolant passages in your engine and other areas.
Possible freeze plug leak at rear of engine block.
remove the blower motor and black box in the engine bay by the blower motor. these evap. cores do leak on the g20s
It's an engine, not a motor, and a number of things. If it's a leak which allows coolant into the engine, it could get into the combustion chamber. This could eventually cause detonation, which could scar and damage the pistons. The vehicle could overheat, as well.
HelloYou have an oil leak is what is means.
The effectiveness of automotive leak inhibitors vary dependent to the level of damage/degradation of the engine, transmission, cooling, and steering systems seals and gaskets. Engine oil stop leaks seal to recondition seals. Severely degraded seals and gaskets usually require replacement.
