Finally got back to the mighty SDL. Couldn't determine for sure whether there was a bad gasket or head, but saw no symptoms of either, and since the motor was unstuck, I cleaned everything up, put in a new crankshaft front seal and Vac. pump gasket, re-assembled, and it runs about like it did before all this trouble. Except for one thing. It now leaks oil from the front of the engine much worse than before the hydrolock happened. When it was apart, I didn't see any evidence that the timing chain cover was leaking, so my only suspect is the crank seal I just replaced. It sounds like I should start a new thread?

thanks
