Audi 80 engine diagram

[matt payne]

Does anybody know of any engine diagram for the audi 80 that is on the net.  
I don't really want to purchase a bentley manual, I've heard that Bentley 
manuals suck and don't show anything. Also, I have been getting a tapping 
sound from my engine (_2.0 litre 4cyl.) at startup and at some times after 
the car is totally warmed. I poured a little bit of Marvins or Mervins 
Magical Oil to the oil, about half a quart, and the sound has yet to happen 
again.  I got this at an auto parts store and it is in a red bottle for 
about 3.00 a guart, alot cheaper than new valve lifters!
