So i've posted here a couple of times about a ticking noise from my engine. 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.

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.

 

Maybe it's sticking valves. Maybe some Marvel Mystery Oil will fix it. It did on my S4.

 

What year and how many miles? Any software? Max boost?

 

Regarding the 40 hours to pull the motor, yes, that is excessive if that is JUST to pull the motor and stuff it back in. If that 40 hours is tear down to the oil pump and reassemble, then that sounds much closer. You are also right, in that, to some degree they all do it, and having seen engines replaced for this, sometimes the replacement engine made more noise than the original. It is believed to be caused by the gear drive from the crankshaft where it meshes with the oil pump drive gear. If that is the case, it might be tough to quarantine something as "broken", unless they are able to find something obvious. Best of luck.

 

I'd find an indy that give you more assurance they will be able to find something...in the end, the dealer will need to convince a warranty company a part has "failed"... what do you do when the dealer says 'the shaft has worn, but is hasn't failed so the warranty will not cover it"?

the noise from intermediate shaft is in tolerance if you have no noise on cold engine, after 5min warming up you can hear on every turbo engine M96/70 noise from the shaft. At this point a professionell must clear if it is in tolerance or not.

the noise must go away if you idle over 1200rpm, if the noise still exist and the rattle goes over 1200rpm the engine does have a problem. I know some 2002 MY TT was louder than others, and for a car like a porsche its not nice. It is very hard to clear it from videos, this is only my understanding and knowledge about this noise.

This is only for the intermediate shaft noise written, a engine can have many noises

 

I can still hear it above 1200 rpm. Actually I can still hear it up to 2500.

 

smooth,

I need to get my post count up before I can pm you. This should do it.

 

40 hrs to just drop the motor is rediculous. what kind of micky mouse dealer is this ?

 

Is this an official Porsche specification/tolerance? Is it written anywhere? What is the source of this info?

If it can be backed up, I would think it is very helpful!

Thx

The kind that has a boat payment coming up!

 

+1 for trying the Marvel Mystery Oil. I haven't tried it personally on my car, but I've seen it used on other porsches and it made a night/day difference in how smooth the engine sounds.

 

if you can hear it till 2500rpm and more it is over tolerance, you must clear if its a rythmic noise with higher rpm and lower than it could be a lifter. (sometimes with hot oil and hot engine and higher revs it goes away..... but with a noise nobody will rev high)

my experience is the intermediateshaft noise isnt a rytmic noise, it rattles like a transmission gear under the car in the middle of the engine

If the noise is unrythmic it is possible it cames from the intermediate shaft, with shims you can correct that, but engine must go out and cost a lot time and work.....but be shure this noise is always a little to hear.

 

I think it includes splitting the case to diagnose. I'm not too sure. I'm waiting to hear back about the oil pump diagnoses first before I give the go ahead to drop the motor. Although, I may just extend the warranty and wait and see. I'm torn right now. Seems unwise to chase ghosts.

 

sometimes you can do with a good oil magic.......i am with you
