Car Forum / Volkswagen / Water Cooled Volkswagen Cars / January 2007compression woes
Well now, got the compression numbers on the vr6 passat that gave up the ghost a couple of weeks ago. Cyls 2,4 and 6 are all around 180 psi (cold engine). Cyls 1,3 and 5, O psi, 60 psi, and 0 psi. Bent valves on 3 and 5? Skipped tooth on timing chain? blown timing chain tensioner? All of the above? Any bets before I take off the valve cover? Regards - Chris Nope ,not from me. 0s are real ugly. It could be anything. Its thorough inspection time. > Well now, got the compression numbers on the vr6 passat that gave up the > ghost a couple of weeks ago.

The good news is that finding the problem won't be hard. Something will be very obviously broken. A peek down the sparkplug holes would be a good start. See if the pistons and valves still move. The ugly part is fixing it. > > Well now, got the compression numbers on the vr6 passat that gave up the > > ghost a couple of weeks ago.

Any way you cut it, you gotta pull the head off to find out fer sher.

A couple other possible causes: Sheared woodruff key or broken (or backed-out) dowel on cam sprocket, broken camshaft (esp. if engine ran low on oil). JRE > Bent valves on 3 and 5?
