Make sure the leak is not the sensor itself I ordered a seal too then found a hair line crack in sensor itself

Good point, I will give the sensor a close inspection.

Update: Sensor is cracked. Starts on top and travels down the side. I think it stops just short of the seal. There is mold seam there as well which makes it harder to verify where the crack stops and the seam starts. I need to get a closer look with a jewelers loupe.

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.

Honestly, I wouldnt use anything to try to fix that crack... you wouldnt want RTV or any kind of epoxy floating around in the oil galleys and I doubt super glue would hold. Its now an official paper weight.

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.
