4.2 V8 Timing Chain Rebuild
Hello Teamspeed 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

This particular car is not under warranty and dealer doesn't even want to bother with it, they tried selling the customer a brand new motor.

Goddamn! Do you know if it requires that much work to access the timing belted 4.2s too? With the engine out? I am having my belt done with everything involving it next week over a leaking crankshaft seal and am curious whether I should prepare for Ramen's for the rest of the year . . .

Would it be weird if I moved overseas to Long Island, just so I could consider you my local shop and talk over Teamspeed?

You don't have to move, just ship the car over! It'll be easier on you

Seeing as I have an interest in this car (I have a timing chain 4.2) I am curious about this engine.
How many miles are on this engine?
What were the symptoms that made you think that there were problems?
Did you do anything else while the engine was out, i.e. JHM Headers or clutch and light weight flywheel? If not I would recommend that the owner look into these since the motor is already out and a motor pull is required to install either of those parts.

He wasn't interested in any other modifications, just wanted the car running 'right'.
