I don't agree, any non serviceable IMS should have the 3rd revised large IMS bearing.
Mine is a August 2005 build, MY06 model, but I have the non serviceable IMS. Which means I have the final revised large single ball bearing.
If I didn't have this IMS design it would mean that my IMS is serviceable, which it isn't. All 2005 models (non MY06) have serviceable IMS bearings.
It's also confirmed in shyamvenky's above post, my engine number is 68514175 - large IMS bearing.
While we're on this subject oil changes are best done every 5000kms to avoid failure or at least check on the possibility. Another way to avoid IMS failure is to drive it like you stole it. Low revs are bad for the IMS bearing. That's why I always try to drive my tiptronic in manual mode as much as possible to avoid driving in 4th gear at 60kmh.
Also ticking noises aren't always a sure sign of IMS failure, I heard slight ticking sounds coming from my engine on a couple of cold starts about 5000kms ago but haven't heard it since. Could of been a number of things but it only happened a couple of times and not since it musn't be an issue.

Fact is (as per Excellence or Hartec, not sure which. I have no personal knowledge) in the early my'06 production run during '05 some cars got new bearing while some got left over old ones. The only way to be sure according to these sources is to visually check. The production dates or vin #'s are not !00% accurate.
It is possible but not probable that OP's car had early bearing. It is also possible that the problem is #6 cylinder failure as someone else suggested. This takes more engines than IMS and can preceded by "ticking noise" from excessive piston/cylinder clearance. Borescoping would rule this out if some one was worried.
Take care and relax my friend. No high performance car comes without a little bit of worry. Wouldn,t be right

Jeez, Joey relax. I get the concern I really do.

What part of my post looked like I was stressed? I am relaxed just because someone disagrees with your post doesn't mean they are getting bent out of shape.
OP - keep us posted on the progress.

good point, unless you check you really don't know.
now i could be wrong but isnt changing the synthetic oil every 5000km (3000 miles) a little overkill?

I haven't seen the filter yet just got a call from the shop , I used them for 6 years so I don't think it's BS , The question is it really the IMS ,as I've never cut open a filter I would think any metal would be cause for some alarm regardless of the size. we'll see ,

could be scoring/d-chunk. i've seen it happen and its also a rare problem and normally happens to higher milage cars that have been beat to death on the track.

From other users post about IMS failures usually they get the death rattle and a CEL and by the time they turn the engine off it's too late and there's a puddle of oil under the engine.
"Lifter noise" with metal in the oil sounds more like it could be piston slap from scoring, but this is all just arm chair mechanic advice.
In any case I'm wishing you the best of luck.

mine went at 59k
thankfully had a warranty - they coughed up $21k for a new engine. porsche used a short block and built up the rest of the motor with my original heads and accesories. porsche has depleted their entire inventory of long block motors.

picked it up in 08 with 12K put another 18K on , several DE's , heard what I thought was a lifter tapping after last run @ Robling Road two weeks ago , took to usual shop had them cut open filter found metal , so everyone jumped on IMS ; o6 IMS requires engine tear down to access IMS , changed oil after every DE, don't know if this matters but this was a early 2006 built in Sept 2005 I think I'll have to check
Was the car still running well? How big are the metallic particles? Did they check camshaft deviation?

Im almost positive it's not IMS. Keep us posted.
