To save space I will be very concise - please don't mistake this for rudeness!
Picked up a Chevy Tracker for my daughter, sweet deal. 130k, engine runs ok.
PROBLEMS
Excessive blow by, low power. Oil is dirty despite being changed < 2k miles ago. A clicking from under the valve cover, seems isolated to one cylinder, most forums attribute it to a known bulletin 00-06-01-006C for "lifter bleed down".
HAVE ALREADY CHECKED
Compressions: 160+ across the board, plugs look amazing despite being a few years old.
Vacuum is good at 22.
New PCV, checked all hoses.
Before I tear off the valve cover and spend $200 on new lifters, unless someone screams 'no', I think my next step is to run some excellent flush in the crankcase, clean that baby out, and refill with new oil plus an additive.
The advice I'm asking for is: recommendations for the best flush product and procedure, then the best additive to leave in for say 1k miles before another change.
Eagerly awaiting a flood of expertise!
