Hi all. Searched and found lots of stuff re: rings, was thinking of putting this on end of SeattleTrainWreck 22R post. But only saw MudHippies' comments on the 3VZ.

Background: had a block, took to machine shop back in May or such, retrieved in early June, then was gone to AZ until last week. So I was starting assembly, and don't even know where my receipts are for parts.

I don't recall why, but the shop needed to rebore (the pistons are labeled 50 over) and I ordered what he stated and had shipped direct to him.

Long of it is, I thot to just check the end gap. Each top ring is right at .020 (maybe a bit slippier on one) on each cylinder. I don't have a 3-4" mic to check the bores. That .020 is inches, not mm's. The FSM (I have a printed copy) puts it at .019 for outer most.

Do any of you have ideas (beside the possibility I really did get heat stroke in AZ) of what might be wrong? Is it possible that I might just have the wrong rings? Even one (only tested one) of the 2nd rings is the same. And, each one is uniform, at 1" depth, and at 4" depth.

I'm thinkin of haulin it to another shop, and pay to see what they say. This really isn't my first rodeo (altho first toyota).

Thanks in advance.

 

Ring end gap eh? Not something I even bothered to check on mine. I sized the bores, which were all still well within STD sizes. So when I ordered up STD size rings and pistons, I figured they oughta be correctly gapped right out of the box. It's caused no problems/issues installing them w/o checking the end gaps. Still running great.

I'd say .020" is pretty damn close to .0197". Close enough that I wouldn't be fretting on it anyway. Besides, the time to worry is when the gaps are looking a little too small, not a little too big. If they were, then you'd need to file them to open the gaps up a tad. You do realize that the ring end gap limit(widest allowable end gap) for the No.1 ring is .0433" right? You're NOWHERE NEAR that.
