Metal in My Oil Filter
OK, so here is my story of woe.:
2005 C2S with 55K miles. I have done an oil change with Mobile 1 0W40 every 5K miles. Yes, I track the car 12-15/yr.
So, yesterday for the first time, I found three pieces of metal in the oil filter. Used a magnet to very it was metal.
Called indie today and his words were as follows:
"That's allot. Do not drive the car. We will flat-bed it here (50 miles). We have three cars in the shop now with blown engines at $20K/piece."
My comment to him. "Might as well install the LSD I was doing this coming spring and lets check the throw out bearing that was starting to squeak and let's do the clutch if needed."
Oh well, at least no one is lobbing missiles at my neighborhood.

Agree with Corsa. What size pieces are we talking here? Sometimes I gain confidence in this car and then I read something like this and you have to wonder again. What production date is your car? I thought just the earlier '05 S motors were potentially M96s. Are you sure you have a single row bearing? Is your engine stamped M96...? This whole issue sucks. 55k miles, doing regular oil changes - you'd hope to be one of the lucky ones. Need to check my filter next oil change. Good luck.

2005 is hit or miss whether you can do an IMSR or not.
Some have the 997 style IMS which is larger than the opening and cannot be extracted
with the IMS tube in the casing.

JFERR,
I have been flying and taking care of personal aircraft and sports cars for a number of years. Engines make metal! The real question is: How much? Airplane guys are used to seeing some stuff in the filter and we are **** about our engines being reliable. Is it is like tiny tiny reflective pieces (smaller than table salt)? . Is it ferrous metal? Did it suddenly increase in quantity or size? Any change in the car's use? Oil type? Don't panic because you have a touch of metal in your filter, that is what it's for, to catch debris. Have a Mechanic look and make a determination. I personally wouldn't truck the car. Just take the filter initially. If they are worth their salt they will guide you after a look-see without any $20K panic bombs being dropped to frighten you.

Here is the data on when the IMS bearing design changed with regard to engine numbers originally posted by holden997. Could be useful for you understanding your options.
-----------------------------------
Base engine (3.6) has designation "M96", has both the older IMS and revised larger bearing, you will need your engine number to determine which one you have:
Engine (3.6) number up to M96/05 69507475 has the older IMS bearing and Engine number from M96/05 69507476 has the larger revised IMS.
"S" engine (3.8) has designation "M97", also has both the older IMS and revised larger IMS bearing:
Engine (3.8) number up to M97/01 68509790 has the older IMS bearing and Engine number from M97/01 68509791 has the larger revised IMS.
The older IMS bearing can be replaced, this requires removing the transmission in order to get access to the bearing.
The larger IMS bearing can also be replaced but a tear down of the engine is required.

do our motors cost $20K? I think the 996 motors are far less, no?

Three bits of metal not too big a deal if build swarf that shows up now and then!! If you're nervous change the IMSB and do an oil change --- sorted!!

^^^ agreed. unless you're talking about sizeable pieces, shavings and fragments are commonly found in the filters and are not a big deal. ive spoken to several porsche techs and all have confirmed this. most often the shavings are created during intial startup when most wear occurs.
ive 110,000 on my 2005 S and change the oil every 5,000 miles religiously. every 15k i have the oil analyzed by Blackstone Labs and they always come back with a stellar review on the condition of the oil and engine.

Good news. Did you do the IMS? Even with the new style IMS I suspect that at some point the motor should be torn down and the IMS should be upgraded. Does anyone know the cost to do this work?

I don't believe you need a better reason to do a IMS retrofit.
