How to check cam/crank sensors????
« Reply #31 on: January 20, 2010, 09:34:58 AM »
UPDATE:

Car has been running great for about a week now so I think the crank sensor was the issue.

I have one more question. To install the crank sensor one should take out the cam sensor to give the wire holder some slack to run the crank sensor where it needs to be. Or atleast this is what I did. I guess i just want to know if I could get an oil leak around the cam sensor? I have since developed a nice little leak and am wondering if it has a gasket that goes on with it. I dont remember there really being one there.

Yeah, it has an 18x2 o-ring according to RealOEM.  It's part 7 in that schematic.  Pull the cam cover & see if its stuck in there somewhere.  I'd replace it with a new one, they harden over time & leak forever after.

By the amount of oil that it is leaking I am thinking it is more of an oil pan issue but I dont think that the sensor has an o-ring. It couldnt be missing anywhere cause we have only about 2000 miles on the motor after rebuilding it. I just need to get the o-ring and put it on there.

Thanks again DesktopDave

I'm guessing mine is leaking from the front main seal or dipstick tube o-ring.  When I get the 325 sorted I'll take it apart for repairs & report on my findings...

Yep.  O-rings for everyone...they're all over this motor.  I'll bet the gasket and/or o-ring in my oil filter housing leaks too.

Motor was freshly rebuilt and all the o-rings were replaced. The only kicker was the care came with no dipstick. Had to source a used and not sure if the o-ring on that is new or not. If this o-ring were dried up could this make a decent amount of leakage? Also, can this o-ring be replaced without draining the oil. I am thinking yes but am not sure.

Thanks.

I'm honestly not sure.  I think you can pull it without draining the oil...it's pretty high on the oil pan.
