2001 Chevy Malibu, had the LIM coolant leak. Fixed that with stop leak. Today I changed the oil and put in M1 HM 10w-30. It really quieted the valve train.
Anyway I know it's sludged from what I can see in the fill hole, and the PCV valve is also gross. I will be replacing the PCV with a new valve next week. For now I cleaned it out with brake cleaner.
Would something like rotella T4 do more cleaning than the M1 HM?
