Well.... Blown HG, Warped Head, Worn Bearings, Rusted Cylinders, Stuck and broken Rings.... What else... I think thats it so far o wait, bad erosion on the the top of block and head.

Im beginning to not like this car any more...

Well after getting the head welded and built up in some spots and then decked we decided to pull the engine...
Got it apart and the rings were so gummy that they needed to be replaced.
The bearings were almost totally shot. Quite a bit of erosion on the top of the block so I sent it in to get welded up and decked and my machinist cold cleaned the block and then honed it too, well what do we find? Very bad rust pits in the 2 center cylinders my machinist recommended that we have it bored. Well I really dont know what to do, Ive already got the new rings so Ill have to try and return them for some over sized rings and then Ill have to get pistons too. What do you guys think Im starting to REALLY get frustrated with this damned car...

Two words.........new engine. It sounds like you'll be spending the same amount as you would to buy a new one.

How much are new engines?

they usually run from about 700-1000 from what I've seen at some sites and eBay.

hey buddy you and i are in the same boat. my car wouldnt run, started it one day and smoked up the neighbor hood, figured it was maybe bad rings pulled the engine, took it apart, warped head, so badly that if it were to be fixed the valves would hit the pistons, oh and there appeared to be a small crack in a cylinder wall... so im getting a new motor... when my bank account stops slipping out money... well good luck with your engine, and god have mercy on me...

I took the exhaust manifold off when i took my head off...lifting the head by itsself is a pain when your bending over the fenders, let alone with the manifolod on it.

I really feel for you guys. All i can say is that the majority of problems with this engine come from coolant and maintainence. I'm in the final stages of a full rebuild, about to put engine back in car. My engine had signs of all the problems you guys have mentioned but not as bad, i was lucky. $130 bucks to preasure test and surface the head, $600 bucks on parts, all a bit under trade as they were organized by a mechanic who helped with the rebuild. All cleaning i did myself, and the bore was honed by my mechanic, i saved heaps, and have been told it will last like any engine as long as i dont put straight water in it,(it eats the engine and cause a heap of problems) and service it like any car. THats it. All coolant pipes and lines have been replaced and im going to use the Toyota Red coolant, it really is good stuff and you dont have to change it like your oil so its worth any extra it cost.
And, if you do decide to do a full build check things like oil pressure before you start it, make sure oil cooler and heater box have been cleaned, and everything torqued right. Goodluck.
