Leading evidence: 'Use 3.4' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'ims bearing has failed(cant be sure at this moment).'' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Run like a bear up' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Used 3.4s that are worth a hoot are getting really hard to find.

His mechanic said 'Unfortunately,there is a lot of metal debris in the oil filter..Most likely the IMS bearing has failed(cant be sure at this moment).'

When I got the car the leak down and other inspections were stellar, and it has run like a bear up to now!
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Tony,
Used engines can be had on craigslist anywhere from $6K to $10K FOB. 3.4L being more expensive than 3.6L. Refresh can cost around $700 to $800 in parts. Clutch will add another $500. Flywheel extra. LNE bearing, RMS, cam pads, water pump and AOS (air oil separator).
Shops will charge around 8-10 hrs for the install. People here have dropped engines on their own in 4-6 hrs.
If you want to keep the car. Jake's 3.6 engine from LN engineering start at $18K is what I have heard.
Thanks - I'll forward this info' to a friend.

The guy who owns dCAuto, arguably the largest Porsche dismantler in the US, told me last fall that any M96 is getting hard to find. He gets several calls each day looking for them.
Thanks to TRINITONY for posting this question for me. It is my 2002 C4 3.6 Cabrio that he was inquiring about. It looks like the IMS bearing let go. When I got the car the leak down and other inspections were stellar, and it has run like a bear up to now! I am not sure what to do with it at this point.
That's a bummer It depends on what you want to do. A running 02 C4 cabrio should be worth somewhere in the mid to high $20s in good condition with less than 70K miles.
Option 1: You can wait and find a used engine to pop up on ebay for $5-6K. Do some preventative work addressing the IMS and other while the engine is out fixes. You can have it up and running again around $10K.
Option 2: Send you car to Jake at Flat Six and be prepared to pay double but no worries about the car's engine forever.
Option 3: Sell as is which is worth around $5-7K and move into a new car.
I really do appreciate all the insight and information, I think it is going to help me in making a decision. Like I said, it is my first 911, never understood the love affair people have with these, but having owned it for less than a year, I now see why what the fuss is all about
Anyway, I'll let you all know what happens in the coming days.
