I live in western hills Sombody has to just kiding we like.

 

I wired a few house in Western Hills. I kinda miss the desert. My family still lives up there. I moved there in '87 and moved out about a 1 1/2 ago.

 

I just called a buddy about the piston rings and he recommends you call toyota or maybe hit up autozone for a diagram. I'd go to Car quest there in town too cause they are pretty good with that stuff.

 

Oh boy thanks a lot for your info sorry for slow reply just trying to get done so I can use Monday for work taking a lot longer than I thought but thank u all.

 

No problem. Hope you get her back together. Let me know how it goes.

 

When I rebuilt my l31 350 the upper rings had a dimple (like a matchmark) on them. You have to really look for it- probably feel it before you see it.

Both rings were marked with a special dye (stripe) on the side that goes towards the top of the piston.

I hope that if you've got the engine torn down this far that you're going to install new rings. The new rings will come with instructions that reiterate what I wrote above.

Good luck.
