I have an Audi 90CS V6 with a problem. The valves are making a bunch of noise. I'm thinking the timing might be off but don't know how to adjust it like I do my other car. I have a timing gun and would use that but I can't even see a timing tab nor does it have a distributor for me to turn to advance or retard the timing. How do I go about adjusting it?? Any help is appreciated.

ignition timing and valve timing are two completely different things
