Time to rebuild, Opinions / Suggestions Options

[BPGREER]

Well it looks like it may be time to tear my engine apart. McMark was kind enough to point out my lack of compression this weekend. It looks like I have about 110 lbs on 2 cylinders, and 120 on the other 2. The motor has 64,000 miles on it (original), but it did sit for 17 years in a garage by the ocean. A guess is that the cylinder walls have pitted. I am thinking about rebuilding the top end. I realize there are some who disagree with ever taking this approach, but being that the engine has relatively low miles I hope it will work out. If I do choose this method, what would you all suggest in the way of cylinders/pistons sets, etc. I am running the orig Djet, so would going with the 96mm setup still function properly? I'm not trying to stray too far from stock (or to spend too much $$$), but wouldn't mind a little extra power. Thanks for any advice.

If it's got 64k miles with no rebuild, it's probably going to need valve guides too. If you don't do it now, you'll do it within the next 10k miles.

My recommendation would be to do a top end rebuild, providing the bottom end is solid. Get the heads done correctly. Replace all seals. New rod bearings, rebush the small end of the rods, Euro P & C's if you can afford it. This would probably take you to at least the 100k mile mark, or more.

If you want to cheap out on it, get the cylinders honed, new rings, replace whatever seals you can afford that don't come with the engine gasket set. This will buy you around six to ten thousand miles.

It all depends on how many times you want to do it.

Either way you will run into some ALA's (As Long As). Like repack the CV's, trans output flange seals, any exhaust issues, and fuel line/pump/filtration/tank issues, rear brakes, painting all sorts of stuff, engine bay seals, blah blah blah
