tappets or piston slap, or???
I get a tappet-like noise when the car is cold, especially under hard acceleration. I can avoid hearing the noise if I accelerate vert gently. I only barely hear the noise when the engine is fully warmed up, but today I heard it clearly under hard acceleration at 170o (I have a scan gaugecar is fully warmed up ~185-190). It sounds very much like tappets, but someone told me they thought it was piston slap. Any thoughts? If piston slap, what's hte prognosis for the engine?

RE: tappets or piston slap, or???
Give the MMO 1000 miles, then run a "once-a-year" engine flush before you change out the MMO and old oil. Gunk makes one that's in a silver can, but they are all the same. It's alcohol that breaks down the oil to loosen up and get all the cr@p out of the engine. You run it at high idle (~1500 rpm) for 10-15 minutes, then change the oil.
NOTE: The second # in the oil designation has to match what your car wants. 0W30 will work fine for 5 or 10 w30. 5w20 needs different oil, with 20 in the second place.
