The 2.5 is a double row IMS and in the original Excellence article it states the 2.5 must have the case opened for replacement, in fact it's one of the reasons Porsche changed to a single row. I am hoping between the time the article was authored and now that other techniques have been pioneered. Edit* link states both dual and single row units can be replaced without dis assembly. Since I'm not sure what failed in my car it may need to come apart anyhow. When I restarted it it was running smooth just with a chain like rattle so I shut it down immediately, not sure what's wrong with it.

Ghostrider,

You are correct that the 2.5s have a double row bearing, however this is a "serviceable" bearing in that it can be removed w/o splitting the case. Porsche returned to a double row bearing in 2006, but this later style cannot be replaced w/o opening the case so yours should replaceable assuming this is related to the noises you heard.

Aron, I'm wondering if it might not be the timing chain, tensioner or the bearing. I was lucky, it failed at idle while parking. For some reason without thinking I decided to restart it as I wasn't really sure what happened. The engine, respective to the way a normal rev would sound was smooth, tight and as regular other than a jingle/rattle, I immediately shut it down and that's it's current state. I have to chuckle, I used the heavier lubricants, changed the oil and filter with ludicrous frequency and even put magnets on the filter case... It was used and although I drove it with respect who knows how it started life.

Look at the oil filter and pull the sump plate to see whats in there. If theres lots of metal, then its probably the IMSB. Mightt be worth a try to replace the bearing, flush the motor with a couple of quick oil changes and pray the metal didn't get pumped through the motor.

Thank you for the input...
