2002 Audi A6 6 cyl Front Wheel Drive 130000 miles

Lack of compression Bank 1. Back cylinder shows no compression the other two 60 pounds. Bank 2 shows 180 pounds on all three cylinders. How can I confirm cam timing? The timing belt appears to be tight & in good condition. Ihave the timing mark lined up on the crankshaft pulley and the valve cover removed on bank 1. So far I have'nt been able to get a diagram showing the timing marks for the camshafts to see if they are out of time.

Hi Charles Whittaker,

Thank you for the donation.

The camshafts do not have any markings. A special tool for holding the camshafts is required. It is placed across both cam to hold them in the correct position.
