leak from oil pressure sensor?
« on: Sep 26, 2012, 05:34:16 PM »
I got a bad leak from the sensor right below the oil filter on my 22re. Is this the oil pressure sensor? Just unplug it, re seal it, and thread it back in?

Is this an oil pressure sending unit (do you have a factory oil pressure gauge) or just an oil pressure switch?

I've seen people use pliers on the body of the sending unit which damages it and may result in a leak. There is I believe a 12mm bolt head at the base of the sender that should always always always be used.

Oil leaks suck, get it fixed quick!

ahhh. Well anyways it still leaked even after i got a new one! Then I took it out and took a closer look, and the block is cracked!  Right where this threads into. Someone tightened it too much I guess.

HOLY CRAP THAT SUX!! It's really tough trying to seal cracks near threads.

If the crack is along the machined flanged surface (of the hole face of the hole), then you could try adding a gasket washer to seal the leak from around it, but that will be tricky with the sending unit's NPT type fitting...

I've seen ppl try JB Weld but it always leaks again eventually.

Best of luck for ya bud!

Goop RTV around it.   (I've done this at a few places, worked too)

Let it set overnight before starting engine.

You may get lucky.
