Hi,
I bought a 1991 318is with the knowledge it had a rod bearing making noise but that the head was rebuilt. Cam trays , sprocket, new cam boxes ,old lifters etc in trunk. Car ran out nice but oil soaked #4 plug every time it sat overnight made it hard to crank and run until it burned off . I find oil leaking from the head gasket at the back passenger side of the head past the exhaust stud. With the rod knocking on #4 I hoped a new head gasket might solve both issues ( oil leak and rod knocking)
I did not lock the cam and crank . Foolishly reasoning that it runs fine now, there is resistance on all 3 and I have the keys and battery is unhooked. Took apart, put together. Torqued all to spec in the correct sequence, put all together w a fresh oil change . It fired right up but making lot of valve noise, doesnt want to idle but above 2000 sounds like she is running fine except the loud valvetrain. I am by no means a expert but they sound dry. Any ideas ? Thanks
