I have done everything I can think of to get the exhaust manifold off of my cylinder head. I have the engine out of the car, I removed the intake, took off all necessary parts, but it seems like its frozen together. The head is an e31 with only 68,000 miles on it, and I want it! I'm afraid to yank too hard on it because of the soft aluminum. Does anyone have any suggestions? Its the original manifold from 1970 and its never come off. The engine has been sitting, unused for over six years, so that might have something to do with it. Any help would be appreciated. Thanks.
