The VIN will not tell you which bearing was originally installed. (I learned that from JFP and Jake's many posts on the subject)

You can look up the VIN on LN Engineering's web site to see if an upgraded bearing has been registered. https://imsretrofit.com/ims-check/ Yours has not:



That doesn't mean it isn't done. Just that it was not registered.

To verify what you have, you will have to take the drive plate off and look at the IMS Flange. Do a little bit of searching for the specifics of each type flange. The truth is out there...

Ok, Ill look into removing the drive plate when I do the variocam actuator swap and ill try to see if I have the double row (fingers crossed). Is there any good source on how to differentiate the difference when you look?

It`s on the picture, inspect the flange, if it`s deepened like the one depicted by the green arrow, it`s single row, if not, as the one marked by yellow arrow, you have a dual row bearing. You can also inspect the bearing itself if you want, after locking the cams and crankshaft and pull the flange, then press the small shaft inside the IMS. You can pull it back on using a telescopic magnet tool.

Sooo with the engine in the car i will remove the shot engine mount and try to get a little more room to get that cam cover and cams out and hopefully I can get this boxster on the road and drive it. Ive had it for 6 months now and i want to get it smogged and registered so i can drive it.
I have a DIL living in MV. Where in OC are you? I might be able to arrange for my wife to visit her daughter and I could go to your place if you need any help (to the best of my ability). Let me know.
