Ive read on a thread, that you can stop noisy hydraulic lifters by adding 1 liter of ATF on the engine, and then changing the oil 1 or 2 days after.
Does this really works ?
Do I have to drain 1 liter of motor oil before adding it, or I just add it on top of the current oil level ?
Wich kind of ATF ?
My car is silent when cold but very noisy when warm or hot. I suspect the lifters.
