Just wondering what you 3100 / 3400 guys do to subdue the inevitable piston slap in your cars. Figured this could apply to w-bodies so thats why I posted in the General section.
My wifeys car is 2000 Alero GLS, that I do all the maintenence on. Its a great running car, only had to do the LIM and both front wheel bearings. ( both inherent 3400 / N-body issues)
The piston slap drives me nuts, its non existant when warm but when its cold, its a bit obnoxious.
Any luck with any sort of additives?
I'm running 5W30 Castrol synthetic and ACD filters.
