I asked how the tech came to this conclusion and he said its based on the sound he is hearing.

They said they would do it if I really wanted to but they didn't want me to spend more money to have that done if I didn't need to.

Very interesting, as well a questionable. When an IMS gets to the point of death, the immediate result is the engine jumps time, pistons hit valves, and worse follows; but the engine stops running forever. I have never seen or heard of an IMS failure where the engine was able to make any sound once the IMS failed.

You need to be under the car when the filter is pulled, otherwise I have no idea what your chosen shop is up to, but in my estimation, it ain't good.

Listen to the experts here on this forum. I am by no means one of them but JFP is. I found particles in my filter when performing an oil change on my 986 and I brought the car in to a pcar specialist for analysis. They dropped the oil pan and told me my IMS was bad and I needed a replacement engine. Seriously. After consulting this forum and the generous contributors I took the car back and drove it home. I pulled the transmission and the clutch/flywheel and got to the IMS. Imagine my surprise when I pulled out a pristine condition dual row IMS bearing. I won't be going back to that pcar specialist again.

Exactly what I thought JFP. It still starts and makes that tacking sound. This shop mostly deals with old folks that are willing to pay to have parts thrown at problems. I really needed your guys opinion on what he was telling me because it didn't make sense.

I'm going to take the car back, get it towed home and check it myself. The only other options near me for the next step are the Porsche dealership in VA beach and a specialty Porsche indy in Richmond, Lufteknic. I can do amateur DIY stuff but this is beyond me.

First thought was to ask you guys when I was on the side of the road. I always appreciate the help on this forum. I've done so much work myself just reading posts and articles.

Check with your local PCA chapter for recommended shops in your area.

Well mine had a failed IMS and I was able to drive it off to the side of the road. And then was able to start it up again. The horrible clatter convinced me to turn is off and wait for a two truck. In truth the damage was done in that first nanosecond

Not to mince words, or belittle your loss, but I would say that if it still ran, yours was in the early stages of failure, but had not completely gone yet. Yes, your engine would have also been full of metal, but the valve train had to still be working. When the IMS totally fails, the crank and valve train go out of sync and this is what you find:



And believe me, these would not run, and one would not even turn over on the starter.
