Hello,
I've had my 2008 Cayman S now for a bit over 2 years and during that time it has been a great car (except for the water pump and AOS failure). I do oil changes every 5k miles, drive it daily, and make sure to warm it up a bit before revving it out, particularly for short trips. Anyhow, I love my car, but admittedly I didn't do enough digging prior to my purchase to find out about potential IMS bearing issues. So, my feeling is that it would be great to keep the car, but not if I have to keep worrying about that darn IMS bearing now that my CPO warranty is over. So I am thinking I either sell my car which now has 88k miles on it or do the DOF. So my questions on the DOF are as follows:
- Has anyone heard of failures of the original OEM IMS bearing post-DOF installation?
- Is 0W40 oil sufficient to lubricate the bearing, or is it recommended to use a different weight?
- Has anyone heard of oiling problems due to the DOF? Truthfully, I would be a little worried about taking away some oil from part of the engine that needs it. But maybe it's not actually enough to matter?
- How much does the DOF installation typically cost?
- Anyone know of good shops in the Los Angeles area to perform this work?
Your help would be much appreciated.
Hopefully, I can get Pedro to chime in. His explanations and investigations into IMS are awesome!!

Thanks for the info! Those are some pretty big miles! And +1 on the California "winter". 91F yesterday in my neck of the woods.
So besides the 5k oil change intervals, what other reasonable engine treatment do you adhere to? With those kinds of miles, you must be doing a few things right.
BTW, my engine seems to be in good shape so far as I can tell. It consumes very little oil and is pretty quiet (not including the exhaust) when it's idling. Also, upon inspecting the oil and filter during changes, they both always seem to be in good shape. Yeah, hopefully I'm not coming across as paranoid. Apologies if I am.

Thanks a lot, Pedro!
I do have a couple other questions. In one of your videos you had mentioned oil seeping past the bearing seal and getting into the IMS (shaft). If I am understanding correctly, the oil can become rancid and acidic over time, etching the balls and races. So when the DOF is performed and the bearing seal is removed, will the oil in the shaft have the ability to easily drain back out into the pan? Also, if oil can then fill the shaft since it's being sprayed at the bearing, does that mean I would be needing any more oil than usual come oil change time?
Thanks, again!
