-- My car's timing chain snapped two weeks ago

[Simply Red]

The Audi's timing chain went about two weeks ago - Oddly it happened after the dealer had it (the next morning from getting it back, actually) - It really doesn't matter - you have no legs vs. a dealer and besides they'd have to dissect the engine to access that area. So in this case I actually do think it was just a mere coincidence.

Anyhow; ?? I'm wondering if anyone has recovered a vehicle from this timing chain issue ?? - again it's an 06 Audi A4 3.2

I bought a really fast vehicle & all - but black'ey can't be buried yet.

anyone else gone through this? I forget the details regarding the engine's structural assembly. There are two types - one where you're basically in a repairable situation or two - you're ****ed.

Help

Please....

the whole idea is to avoid the dealership and look for other options, stop trolling.

I think if it were me, I would shop for a salvage engine. I would find a car that you can tell it was junked because of an accident, and the engine is still in good shape. It's been my opinion that it was wrecked, it must have been running ok. LOL

Not trolling son just being honest! The dealership may be the only ones who can mess with the computer when it needs reset. I would check around for a Audi/European specialty shop and get some answers over the phone. Good luck

I'd guess you're probably ****ed. It looks like the 3.2 had a timing chain, which is more complicated than a timing belt.

Here's the instructions for changing the timing belt, the easier of the two...

Either way if it's broken or slipped if your motor is an interference engine it's almost certainly done.

The difference between interference and non interference is that in a non interference there is enough valve/piston relief that even if the valves are fully open they won't contact the piston. Hence the valves and pistons don't interfere with each other.

In interference motors they do and frankly if you've got a high performance engine it's almost certainly and interference motor. It would take a pretty low compression motor to be non-interference.

In short when your timing chain breaks one or more of your valves stays open. You piston comes up to greet said open valve. Pistion V valve and the piston wins. Valve bends and then generally breaks off. The valve head now drops into the cylinder with the piston and proceeds to beat the shit out of the top of the piston, cylinder walls and head. Remember you motor is running at N thousand RPMs per minute. Even if it shuts off quick it's too late.

In short if it broke your motor is toast(if it's interference). Technically it can be possible to fix it but you'd have to replace the cylinder sleeves, the pistons, and the full head at minimum. It would very likely cost significantly more than a new motor and be less reliable.

But how many miles are on the car? Timing belts are designed to be replaced. But if I recall most if not all timing chains are designed to last the life of the motor.

Just checked the 3.2L and it's 12.5 compression so it's definitely an interference motor. Sorry if the timing chain broke it's toast...sometimes you get the short straw with these things.

24 valve 3.2 liter DOHC V6, you have three different timing chains if I'm not mistaken. 1 timing chain per head (you have two of those) to drive both camshafts per head, which are in turn driven by a gear that connects the third chain to both heads and the crankshaft.

I cannot comment for sure on whether or not it is an interference motor. If it is, the timing chain risks piston to valve contact and some hefty repair work. If it is not an interference motor, you're fine, just replace it.

How many miles on the car? That should fall under power train warranty, if there is one. Some cars have 10 year / 100 k miles power train warranty.

This.

If a timing chain failed I'd be surprised. Timing belts are usually replaced every 60k miles (some have longer intervals) to avoid breakage and damage to the engine.

You have bad timing.

buy american next time?

Well, I'll tell you one thing from experience.

you're definitely going to need some 30 weight ball bearings and some quaker state anti-freeze. No, wait a minute.....you'd better make that Prestone.

Hey! It's all ball bearings nowadays. Now you prepare that Fetzer valve with some 3-in-1 oil and some gauze pads. /Irwin Fletcher

Yeah that should work "if" the inverted thrust reverse turn lock bolt didn't cut loose when the chain broke. I bet you didn't consider that did you, Mr Charlie Daniels of the torque wrench.

interestingly enough, I see a new "Like new '06 Audi" having just shown up on Craig's List - for our area.
