I'm trying to replace the cylinder head on my 87 325is but when I tried to line up the TDC, I can not turn the crankshaft. This is the fourth or fifth time I replaced a cylinder head but this is the first time I'm having trouble turning the crankshaft. Could it be the pistons got rusted? Coolant was mixed with oil when I drained the oil and the car been sitting for 2 months after the head gasket blown. Anybody got any idea why the crankshaft got stuck? The car is 5-speed. Your advices/comments are greatly appreciated.
No, it was not running when I took the head off, in fact, it died on the freeway while I was driving have to towed it back home. Sat on the street for 2 months before I have time to work on it. I'm going to give it a try now and I'll update you in a few hours. Thanks.
No, the timing belt did not break, it's one piece when I took it off. The car overheated before it broke down on the freeway. When I drained the motor oil, coolant came out first for about 5 second before any oil started coming out. To lube the engine is to pour motor oil on the pistons?
