Intermediate camshaft bearing failures????
A mechanic friend of mine just called and said they've been seeing more of these issues lately for the '07 and '08 years. The shaft bearing can give way and drop down, causing massive damage to the engine.
Has anyone heard of this?

I have not heard an increased occurrence in the '07 / '08 years, but Excellence magazine did an article a few months back about a tool which could save you tons of money and which I read with much interest.
Google 'IMS Guardian' and you will be able to read all you need to know about this solution (around $400).
I'm not linked to this company or product in any way, but if I were more paranoid, this looks like it would be money well spent.

If you are new to this problem search IMS here and on Renn.

I've yet to hear of a single IMS failure in a post mid year '05 911. Does anyone have direct knowledge of an IMS failure in a post mid year 2005 911?
I just had an oil analysis done By Titan here in Denver before starting my supercharger install. Nothing abnormal in my '07.
As a cheaper alternative to the guardian, they make magnetic drain plugs that are supposed to collect shavings, so while not perfect, if you change your oil annually, you would have knowledge of shavings accumulating in the pan.

I'm curious why you don't just do the IMS bearing swap just for peace of mind. In a way, that's better than having a later model because the bearing upgrade can be done, even though I haven't heard of a later model having an IMS bearing failure...

My Indy says they can 'upgrade' at anytime or when they need to replace the clutch, but my clutch typically last well over 150K miles. The IMS is fine. My Indy is reputable and they race a lot of Porsches. I have no warranty, and I can sleep at night. Besides, I saved enough money buying private party that I have an exploded engine fund. The risk of an IMS failure is low. But, I understand the value of preventative maintenance. Otherwise, I would have bought another Toyota. There is no free lunch.

I put my money into an extended warranty instead. It covers a lot of more common problems and also gives me peace of mind for the bigger stuff. But I admire the guys who play the odds in much the same way I admire surfers or anyone else who can put irrational fears out of their heads and just do what they enjoy.

I'm assuming you're asking about IMS even though you said camshaft. Pretty good answers so far.

Had no issues with my 7 1/2 yr old Boxster and none with my 5 yr old 997.

So I guess I'll report back when I blow up too. Still haven't needed clutch replacement, so I guess I'll do the retrofit then.

The IMS swap is NOT a permant fix. If you read they will tell you in will need to be replace again as it is a wear item. IIRC it was every 50k miles.

Out of [conservatively] many hundreds of M96/M97 owners I've met/known, there have been less than a handful who had an IMS issue. Personally I've had none w/ my 10yr old Boxster nor my 5 year old 997.
Bottom line, yes there have been some issues but not nearly to the extent the gorilla marketing/marketers behind the "upgrades" want you to believe...
Good luck
