[TPR] The Good, the bad and the ugly . . .

[asajay at asajay.com]

If lobes on 2 and 3 were bad, I'd guess improper rocker adjustment on  
them, too much pressure, premature wear.

The rings might look like chrome but might not actually be.  You'll  
probably need to extract them and have a professional take a look.

Rings turning on the piston?  My thoughts have been along the same  
line as yours, but it was a professional from a piston maker that told  
me different.  My personal jury is still out on that one.

Photos of:
- the cam
- the lifters from those lobes (contact and pushrod end), vs. others
- #8 bore, vs. any other bore
- #8 piston, vs. any other piston
- Main bearings
- glyptol pieces (if they've not already been cleaned away)
- the lifter valley and heads where the glyptol was applied

Thanks,
Asa Jay
