Apparently I have a slight oil leak at my CPS. I know the crank pos sensor has a replaceable O-ring (I've done it) but is there a simple O-ring for the cam sensor? Looks easy enough to get to the sensor, but at +$70 to replace the whole thing, I'm hoping someone knows if replacing just the O-ring is feasible.

 

Hey Filmy!

The o-rings are cheap:

Getting to the cps is a different story, you have to move the radiator to do the job right:
Clean the area around the cps (it will be very dirty)
Remove the cps
Remove the old o-ring without scrathing the groove it sits in (use something plastic or wooden to pick it out) if you scratch the groove, it will leak.
Clean the cps and the hole in the block so clean you could eat off it
Carefully put the new o-ring on the cps. Any scratch or nick or dirt on the o-ring will cause a leak.
Wipe some clean motor oil on the o-ring so it slides easily into block, and reinstall the cps
Put the car back together, and you're good to go!

 

I need the camshaft position sensor O-ring. Which resides behind the passenger-side upper engine mount.

Looks like it's available everywhere, typical $3 part. Thanks again Rogue.

 

Oh. Oops.

Never mind.
