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. http://sphotos.ak.fbcdn.net/hphotos-..._1953613_n.jpg 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. http://sphotos.ak.fbcdn.net/hphotos-..._1401051_n.jpg http://sphotos.ak.fbcdn.net/hphotos-...6_952580_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._3022537_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._3681701_n.jpg New guides etc installed waiting on new adjusters http://sphotos.ak.fbcdn.net/hphotos-..._4705930_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._3336744_n.jpg 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 http://sphotos.ak.fbcdn.net/hphotos-...8_712826_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._4889791_n.jpg http://sphotos.ak.fbcdn.net/hphotos-..._6618257_n.jpg |
Interesting. Isn't this car still under warranty? Is the local dealer not capable of finding/fixing the problem? |

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 . . . |

The timing belt service much simpler to do on the belted 4.2's so don't worry. :smilie: |

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