So I had my mech. Look at the car today and he says that the belt looks fine but that key to the camshaft gear might have sheared its self off. Anyone else have the this happen to them.

The only time i've seen the cam gear shear the key is if the cams locked up due to oil starvation.

What about a lot of hard shifting on a long road trip

I bought the car with the cluster completely depixelated, so I couldn't see the low oil light, driving home and it just shut off, tried starting, towed home, later to find the key broke off due to oil starvation, changed pickup tube, cleaned oil pan, changed camshaft chain tensioner, changed turbo, changed the oil couple of times with very short intervals, and the past 1.5 years have been changing every 2k miles because sludge keeps falling off, running strong at 19 psi stock turbo, never touched the head valves were fine, if it ain't broke don't fix it

Shoot I get what your saying now. Does that mean the whole head needs to be replaced?

I disagree in your situation. If the key sheared, I most definitely would fix it. If you say the head gasket needs to be fixed anyways, fixing the key on the camshaft is hardly a detour from the HG job

They want to rebuild the whole head now ugh

What is actually wrong with car? Is it a blown head gasket? Sheared keyway? Bent valves?

I'd be hard pressed to believe it has all those problems. Just fix what is broke and call it done.

We'll I talked to them they told me the key was not sheared. It was out of timing but ... It now has oil and coolent mixed soo they are getting me an estimate! Any idea how much it would cost to rebuild head?

I don't understand what is wrong with the head. What exactly do they want to do with the head? And your oil and coolant mix can be a failed oil cooler.

From what I'm hearing you could have a bad t-belt tensioner (allowed timing belt to jump), and an oil cooler that's swapping spit. That would be best case.

Be careful.

Okay here's a story I originally took it and because it was idling rough and the turbo wasn't boosting right they told me that if the timing was off by two teeth because the key was sheared on the camshaft so they fixed it but it was still idling rough so they looked at it for spark plug and said that they saw steam coming out of it so they told me that it's a head gasket and most likely the head is messed up...

I also had a check engine light for multiple misfires and the crank and camshaft position sensors said there was incorrect correlation

Oh, gotcha.

Seems like they just want to replace the head gasket and possibly shave the head. I don't think they need to do anything further than that. But I wasn't there. And I'm not a mechanic.

Yep he said they want to mill it. Would that give me more compression/mess up my tune?

$2000 will get you an entire running B6 A4.

$1200 will get you an entire 1.8T engine, shipped to your door. That leaves $1600 for somebody to throw on a new t-belt and bolt it in for you.

But $2800 sounds reasonable. lol

Excuse me, but that is fucking ludicrous! I sold my used AWM engine with 150k miles for $1000 cash. Whoever quoted you that should get got.

? If the key sheared than it is broken... Than you have to fix it, what I meant was just change what is broken, for my example, everyone would have thought I needed to change the entire head and valves, not the case

Mis understanding. I thought you meant don't fix the broken key!

I can remember a couple threads where the key was broke and valves didn't bend.

OK since you are on the topic i found this in my town http://jacksonville.craigslist.org/pts/4318552188.html .. could i just swap stuff in and out and sell the rest as a part out? mine is a atw not sure what this is yet? I got him down to 1500 for it all. Says it drives. I have a tuned ecu i could just stick in and be done with it!

The ecu and harness wont swap over. There are some differences between ATW and AEB cars, but a lot of the hardware is the same.

I'm sorry but I have no idea what year your car is. If it is 2000, you have an ATW engine. Anything less than 2000, and it is AEB

That is a pre-facelift A4.. Not sure how it is 99.5?

I was talking about op's car, but yeah, the craigslist post is pre facelift, meaning an AEB engine for sure. Seller isn't aware what a facelift A4 looks like

ECU's are 50 bucks. There must be a lot more wrong with that car than just a bad ECU.

That said, it sounds like a deal for $1500. Especially for an Avant.

Is it just me or do we NOT know what year your car is? Or which motor code you have... I thought I saw something about being a 2000 ATW. but I am still not sure..

Op give us specs on your car. Motor? Tranny? Quattro?

Your link is broken, but what you need is either an ATW head or an AWM head. You'll have to swap over your intake cam and chain tensioner from your old head if you buy an AWM head though. You could also use heads from transverse motors, MK4 pre-02 heads should be a direct swap to an ATW, after that you'll need to swap the cam and chain tensioner. The best way to tell them apart would be to look at the cam chain tensioner, if it has a black cylinder with a plug coming out the side of the tensioner it's VVT and not the one you need, you need the one without it. For example the first one you posted has a VVT tensioner, which means it's an AWM head and you'll need to swap parts.
