Im trying to find out what this sensor is, and what the substance is that is leaking out of it. The pictures are from the passenger end looking at the side of the timing chain cover.

 

will u zoom out a lil bit. i think i have an idea.

 

I think it's the crank angle sensor. I'm positive it will tell you in a Haynes manuel. My guess is crank angle sensor.

Just checked my manuel it's the crank position sensor!!!
And more then likely its motor oil leaking out of it?

 

hmm.....i couldnt tell ya off the top of my head. that little wire just goes off into the rest of the others. best bet is to look into a haynes manual. im at work so i dont have mine with me, but if no one has replied by then ill let ya know.

 

Actually it's the CAMSHAFT position sensor(PHASE).

 

Big D is correct camshaft position sensor, Crankshaft position sensor looks the same.

 

They look similar but the location is different.

 

oh yea.......... looks like oil leakin out

 

Does that sensor have an o-ring?

 

Yes, it has an o-ring. Mine leaked in the past on my old motor. Nothing that good old permetex ultra grey can't fix......Or you can go to your local hardware store and "try" to find a right sized o-ring, or you ma be able to order it from Nissan.

BTW, that is oil leaking from the sensor......

 

I have some permetex left over from my valve cover gasket job.

Is that a problem that it is leaking from the sensor?

 

Probably not but if you're like me, you don't want oil leaking out of anywhere.

 

Exactly, I notice things that people never know was there.

 

Nah, you are fine. Just remove the one 10mm head bolt, through a little permatex on it and slap it back in. Remember not to use too much as it may hinder the sensor from actually working.....
