Hey, I took valve cover off, and it looks like the cam sprockets are not aligned. They are 1 tooth off from each other, so if you turn one straight up (arrow up on end of cam shaft), other end is at an angle about equivalent to 1 tooth of the sprocket.
How can I find top dead center on my 1991 318is M42? How can I know which cam sprocket is off by one tooth? How can I be sure it really is off one tooth like I think?
The problem is the chain was replaced, and the car makes horrible noises at 4k rpm and above. Exactly the symptoms I have heard can be caused when the timing was way off. I do not know who did the work on this engine, or I'd talk to them.
