Working on a Tracker

[Prismo]

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.

OK, I have a computer to post with again. Here are the cams. I used the gauges to measure the bores & double checked my readings with the caliper. Everything is within spec so I am moving forward. I used 1200 grit paper to smooth the scratched bores, cannot feel any scratches now.

Do any of the Valves appear to be lower that the others? Tip of the valve that contacts the lifter.
what kind of sound?
is the sound engine speed?
Or 1/2 of engine speed (indicating valve train noise)?
nothing to see on the cams. no scissor gear on them.

I tracked it by sound to the top of the engine at the front where I found the scratched lifter bore, it was definitely top end related. No broken valve springs or anything odd looking. You could see where the lifter was catching in the bore & there was a piece of hard carbon in the oil ring around the lifter when I pulled it. Sounded just like a badly adjusted valve in a 22re lol

Well, we sold the Tracker last month.
Figure I would show you guys the new removable mudflaps I made this week.

And then it was "Hammer Time". I have nicknamed my buddy hammer hands, he over tightens everything. His custom "scoop grind" cam.
