Hello 6Speed Audi forum. I just wanted to show you guys some pictures of a car/motor that we've been tearing apart and doing an overhaul on due to the customer bringing in the car for it not idling and being driveable at all in which we believed it was a timing chain tensioner & guide issue.

Onto the pics...
Here is the first picture with the car with the engine/transmission removed.

We took of the rear cover and this is the first thing we found. One of the chain guides were broken on the left bank.




New guides etc installed waiting on new adjusters


Upon further inspection and taking apart the tensioner/adjuster itself we have found that there are spots of extensive wear which has caused the cam to be not aligned as seen below




Discuss!
Once the parts are here I will update this thread with further pics and info. Stay tuned!

 

How many miles were driven on this engine?

 

Little over 80K

 

In this case, I'd rather the thing have a timing belt in the front. So much for less maintenance!

 

This case is very rare to happen but if it does this is what needs to be done on these motors. This is not routine maintenance, more of a fix/repair.

 

Interesting (and expensive lol) problem. Any idea what the route cause was? Was the car tuned? There must have been some extreme torque on the chain to warp the tensioner like that

 

80K miles? Wow. Kudos to the owner for driving the car often.

Any idea how many clutches this car has gone through?

 

Still on the stock clutch.
