Hello Everyone, New to this Forum!
I have a 1992 318i and I just replaced the head gasket. Engine was not making any abnormal noises before this repair but now it sounds like a tractor!
Here is what I do know: Chain and sprokets look good (At least to me they they look good. Tops of teeth are square.). Only 80,000 on the car.
I changed the tentioner twice and noise is still there.(Yes is was compressed when installed)
The noise seems to be coming from the chain and cam area.
Is is possible I could have done something when puting it back together to cause the head not to get oil pressure? However, when I run the engine with the valve cover off plenty of oil is flying off the chain but I dont see any flying off the cam lobes.
All timing is on the mark and head was torqued to specs.
One other thing. I do not have the cam lock tool but marked the cams to the sprokets at #1 TDC and put it back in the exact same position.
Then engine idles well, responds well to acceleration, and starts right up.
Any ideas? I am stuck!

Try pulling the oilpan to check for plastic bits from the timing rails and pan bolts. Check the up oil pump pickup. Not sure about the head oil pressure... any warning lights?
Did you re-check timing after starting the engine?
What prompted the head gasket change?

You sure you put the correct head gasket on? Maybe an oil passage is getting blocked? Worst case scenario I know, but just thinking out.....type..... lol
