Yes but..... it?s not like I can just run to NAPA and replace it. It still works. The leak was minor. The oil pan gasket leaks much more. It seems a little super glue in the crack with a skim of high temp silicone would be worth a try. Epoxy may be an overkill and more risky. My guess the sensor itself is bedded in epoxy internally and should be fine even with a crack in the outer shell. The crack is barely visible.

I agree with you to attempt a repair. I didn?t see the crack you have, but I repaired the one on my 90 with very minimal JB Weld and it was fine.

Just get one from Phil and be done with it... I had mine in a few days and all has been well since.

Update:
Repaired the crack with JB weld for plastic. Used a Dremel to plow a small groove along the crack to give it more bite and roughed up with 180 sand paper. Use silicone around the o-ring seal as well. Did not install until everything had cured. So far no leak. Need more heat cycles to be sure but why not try.

As luck would have it I ordered a new one from Phil but if I can, I would like to try and repair the crack if possible. The sensor still works. Any thoughts? Super glue? Epoxy? RTV? How much clearance between the sensor and the cam?


Only a little oil cam out when I removed it.
Phil has cam position sensors?

Gentlemen, is THAT the crankshaft sensor?!? It's located right below the left cylinder head (driver side). Mine is leaky but it isn't round. I removed a small metal piece (like a small fender, tray, latch, whatever) that was secured with an 8mm nut.
The Sensor itself seems to be not round, there is no twisting possible. I can wiggle it, but it doesn't come out. What am I doing wrong?
