Trying to get the girlfriends Tracker fixed to sell, way too many cars & trucks here. It had been making a rattling noise in the top end. A friend gave me brand new lifters for 40 bucks so I dug into it. Found only one obvious sign, scratched bore & lifter & a bit of hard carbon caught in the lifter oil ring. Other than that there was normal polishing at the top & bottom edges of the lifters on a 180k engine. I need to buy a set of bore gauges & check the lifter bores for diameter tomorrow. The scratches are not as bad as they appear in the picture but they are present. I am honestly thinking of smoothing the bore with 1500 grit paper if the bores mic within spec.
