Is IMS failure more common in the 2.5 ? I have a 3.2S that had its RMS done at 60k.....
I believe it is the same bearing. If that is the case then the extra pressure from the higher powered engine in theory would give it a shorter life.

How much to replace it before it breaks? As you would possibly another wear and tear part...

Its about a grand or £1500 or so with the clutch at the same time.

Depends where you go of course.

I didn't know you could possibly detect the failure before it happens...

"Another way to check the engine is with the factory PST-2 tool, or the Durametric tool (see Pelican Technical Article: Reading Fuel Injection Fault Codes / Diagnosing Problems). You can compare the deviations in the timing between the two camshafts to see if they vary widely, particularly when revving the engine (see Figure 18). Sometimes a failing IMS bearing will also trigger a “check engine light” warning on your dash, as the car's computer realizes that there is a significant deviation between the two camshaft readings."

Interesting...

What's the theory as to why the bearings get wet? Degradation over time of the seals?

I'm hoping my 12 month old revised IMS leaves me in a better position than std.

If for example it did cost £1000 to replace prior to breaking, I would think that value would at least be recouped when you come to sell. Especially if Hartech had done it?

A lot of potential buyers would be encouraged by the fact it had somewhat of a guarantee, over a 70,000 mile one...

Opperchancity to get a 996 engine in there?

Do a little preventative maintenance on the new engine and haway you go.

Note : God knows how much it'll cost in the end.

Update.....copy and pasted from another forum


My Boxster practically died in December.

It was an extremely wet day and I drove from Bristol to Birmingham in my 2000 Boxster S with 70,000 miles to collect my friends new to him 2004 Boxster. On the way home I was on the M42 on a continuous throttle at 65mph and there was a massive shudder throughout the car. The check engine light started flashing and I immediately pulled over to the hard shoulder where, as the car was coming to a stop it died. I attempted to restart the car and it was very hesitant to catch and then it would start and sound really rough and then cut out again. The AA came out and plugged diagnostic equipment into the car which said there was an engine misfire on cylinders 1 and 3. The codes were cleared and I restarted the car. This time it caught first time but it sounded terrible. Really rough and lumpy and pretty much like a cement mixer. I turned the car back off and it was recovered to Porsche Bristol. They performed small checks on the car and they said they found small metal particles in the oil filter. This is as far as i let them take it as they wanted £2,000 to diagnose the fault and £9,000 for a second hand engine!!!!

I had the car recovered to my house so my dad could have a look at the car. It is worth mentioning that all of the coil packs were changed last year by Porsche.

So far the gearbox, clutch and flywheel has been removed from the car but there seems to be no damage to the IMS bearing. It is fully intact. The bearing moved when the flywheel was removed due to the tension on it but it is now back in the middle and has not slipped on any teeth or cogs etc.





I am not sure whether Porsche checked the filter properly as there was still a lot of oil within the car.



Seeing as the IMS bearing appears to be fine, I am wondering what else could have caused this? I have heard a bit about the camshaft solenoids or perhaps it could be a failed conrod. I think our next job will be to rotate the engine by hand and see if there are any unwanted noises from inside the engine but I am wondering if anyone has any other advice of what it could possibly be??

Cheers!! I want to get it fixed so it is ready for the sunshine!!!

I'd probably start by removing the plugs and getting a borascope in each cylinder. It could be a timing chain failure or the chain tensioner,

Thats pretty rude, no need.

Keep us updated OP, if you have a Windows XP laptop I can lend you a borescope kit if you need it.

I think that its tone is well considered. Trying to buy it was rude, after that a rude reply is to be expected.
