Since my last thread went so smoothly Figured I`d ask another dumb question since I`m always trying to learn, (don`t know much about bottom end stuff)
Just wondering if this is normal for the piston to be so nasty near the exhaust valve but looking good everywhere else. ??








Same piston.

Dan are all 16 like that one or are there only a few? only one engine with a few?

to me it looks like burnt oil deposits.the bottom picture looks like the second ring is a zero gap ring.edit in,also looks like the oil ring support rail is missing.can you move the oil ring pack up and down?

Second ring looks gapless to me

I think the what appears to be a gapless second ring, may be the top oil support rail. looks like it has been moved up to that spot upon removal of the piston, that gives the appearance that it is missing from the left side of the upper oil ring pack. my eyes are not as good as they once where

yes.after seeing it blown up i can see the oil ring support rail and yes it is a zero gap 2nd ring.

that really shows how hard it is to tell what is going on with pictures posted on oso.
