Will I need to re-ring my pistons?

Yes, moly rings. I misspoke. I don't take you for an ***. You seem to know what you're talking about, and from what I've seen, you give sound advice and pull no punches.

lol, yeah I guess that's a good description of me. My wife, Kitty says the same thing often. I don't know man. 42K miles and burning oil. I'll be damned if I don't think I would just do a fresh overhaul. Since you "know how" you got the labor licked right there. Parts are comparatively cheap, so "there's THAT". It sounds like the heads are comin off either way, so you're halfway home. Course, you da man and nobody can make that decision but you. Is this the original engine? I fit is, must be a Canadian car. They used the Poly one more year. I like those motors, personally. Cool stuff.
