A: Before you do anything major, if you have compressed air, put some into the cylinders to see if there is a buildup in the rad. (listen with the cap off) I hate to say it, but this sounds like when I had a motor w/o antifreeze (just water) sit through winter and it was cracked along the bottom of the cylinders. Another possibility is a missing freeze plug in the water gallery behind the timing chain (can't recall if AMC did that, but Buick did and lost numerous aluminum block motors because of it) or no gasket between the timing cover and block (water runs down the back of the waterpump directly into the pan through the mounting bolts) From: Tom Jennings <tomj@xxxxxxx> To: AMC List <mail@xxxxxxxxxxxx> Subject: water in crankcase... stupid question... Message-ID: <20050527174859.K1488@localhost> Before I pull the block out... It seems likely that the headgasket is on backwards -- or missing -- or some other stupid problem. I'll pull the head, on the car, to check. Easy enough and makes engine pulling easier anyways. QUESTION: If I find the problem [say backwards head gasket] is there any chance of drying this thing out without tearing the whole thing down? It got water in the crankcase, definitely. Quarts. But it never RAN; there's no serious mixing and it never rose above room temperature. The crankcase was clean when I installed the oilpan; it had not been previously run with this problem [which really makes me think someone removed/restored the head and did a crappy job], there would have been evidence. More, I brought up oil pressure days ago, multiple times, with no water in it; I added water only this morning at the last minute before cranking. However, I have to assume it pumped water through the galleries. Maybe run something hydrophillic through it, like alcohol and oil? This seems desparate as I write it :-)
