  1. The heads were removed on Thursday and some scoring was noticed on the passenger side camshafts and lifters. They stated possible oil starvation on that side , as the driver side cams showed no sign of damage. The crankcase was split on Friday and they noticed the intermediate shaft bearing had failed and the bearing surface toward the other end of the intermediate shaft was really worn to where you could see a copper like color. The dealer is going to write up their findings and submit to my warranty company. I should know what the decision is by the end of next week.
  2. That's a relief to hear. I should hear more from the dealer on Monday or Tuesday. Hopefully, it's something else less major.
  3. I posted over at the 6speed forum about a ticking noise from my engine, thought I'd get some feedback from over here as well. I've pretty much just chalked it up to normal engine noise from reading some posts here, but since my extended warranty was coming up, I decided to take it in to the dealer to get a last look. I was told that the noise is louder than most turbos they've heard and that it would require them to drop the engine to diagnose. They said they will remove the oil pump and check that first, as that is where they think the most sound is the loudest, but I believe the suspect something else inside the motor. They mentioned maybe a camgear or something. Since, it is an extended warranty, I am stuck with the labor cost of pulling the motor in case nothing is broken. If they find something then I'm ok and the extended warranty will hopefully cover the labor and parts. Otherwise, I'm out $5000 just to pull the motor (est. 40 hrs labor) . Does that seem excessive?? Anyway, my saving grace here is that if there is something, then I have an extended warranty I've noticed another previous post that seems to be exactly what my diagnoses has been and it was an intermediate shaft failure. I also had the chain tensioners replaced in response to this problem. Here is a link to some vids of my car when you hear the sound: and when you don't: seems the noise is not present when the motor is cold. When it warms up then it gets pretty loud. Odd since you would think the the engine would tighten up when it got hot. So, I think that eliminates chain slapping. Here is a link to cpu77's problem that seems to be very similar to mine. http://www.6speedonline.com/forums/996-tur...thanks-umw.html any of you know what the difference is between a gt2 motor and TT motor? is it less prone to this type of failure? I thought they were both the same split case design.
