1992 325si e36 sounds like a diesel truck
My son bought this 325is a few months ago, got it hot, cracked the head, bought a so-called used complete head off a "dismantler" that looked like it had been gone through...it was clean, had a new thermostat, looked like it had been milled maybe...He put it on and when it starts up, it sounds like a diesel. We pulled the coil wires and turned the starter over and no bad sounds. It's not a tapping sound, but like a loud diesel truck when started. We've only run it about 15 seconds total. It almost sounds like the valves are hitting the pistons, but we should have heard something in the turnover test. One curious thing, the head gasket metal rings looked liked they would almost hit the valves it was so tight but the gasket kit box had all the right numbers. Any ideas?
