Help CMP sensor bolt striped S90-V90

I'm posting in the s/V90 area as this is the real 960 forum, any way I have been leaking oil from somewhere, turns out it is from under the CMP sensor. The PO has messed the botom bolt (not the original torque type) and it canot be removed as it spins without coming out. It feels like it's the wrong size. I can't even fit any of my standard tools in the tight space. It's leaking about a quart a month from here.
How can I get that thing off.

Thanks

Try taking a long necked flat head screw driver and applying pressure under the head of the bolt while your trying to back it out, this will cause it to bight the threads and hopefully you'll be able to extract it.
Good luck

I've never been in the vicinity of one of these cmp sensors, I know it's at the back of the engine and mine doesn't leak so I've stayed away from it.
I belive there is infor in the facts pages for removal and installation
for this part. I've read the info so I know it's there, You may try to take it out clean the part and go to yor freindly Volvo dealer and get the right bolts to replace the ones that didn't fit along with what ever seal there may be used in that location also.
If you have read any of my other posts, I'm a beleaver in this stuff
Called auto-rx. The stuff will renew seals and help stop all sorts of small oil leaks. Reach them at WWW.auto-rx.com
Good luck

After going to the faq pages under cam position sensor which I think we are talking about, the responce to the leak you have is that you need to take the car to the Volvo dealer to have a new seal installed. From what I read of this there is so little room back there that Volvo had to come up with a special tool to press this seal in. If it's leaking as much oil as you say this would be the only way of repairing the problem short of pulling the engine.
I hope the bolt that you took out isn't completly stripped or you may have to have the durn thing pulled to repair the threads there as well.
Good Luck
Poolman
