Crank Position Trigger O-Ring?
Been fighting a good oil leak at the rate of 1/2 quart to a quart per tank of gas on my 07 RXT. Had the pto boot off and it was dry, oil cooler dry, all the usual stuff etc. Oil was going in the hull! I bought one of the dye kits and and ran it about 15 mins. Looked around with the light and didn't see anything other than dyed oil in the hull. We yanked the motor tonight and found dyed oil all around the crank position trigger on the bottom of the pto housing. The bolt was tight so we took it out and it basically fell out of the housing and there was no o-ring on it.
Now the big question. Is it supposed to have one on it? The microfeche doesn't show one, but I have seen them with and without o-rings just searching the part number online. I would think it is supposed to have one because there is oil pressure in the pto housing right?

yes it should... just take the sensor to the hardware store and get an oring to match up.. that's what I did and it fixed my oil leak after we swapped my head

Cool thanks! We tried some o-rings out of a set and the profile was to big. I might just grab a new sensor so I know it will work fine. Yeah I know $$, but I really don't want to pull the motor again. I could think of a few other things I'd rather do with my free time

I'll see what I can find at the hardware store. I'm just glad it was something easy. The previous owner said he never noticed a oil leak.
