He might be confused. The crank sensor is nowhere near a source of oil. He may have meant the cam position sensor. There are two on your car, on the front face of each cylinder head.

tha cam position sensor uses an o-ring.
the vanos solenoid uses a gasket. solenoid is more likely.

The vanos solenoids are mounted in the front of the heads below the cam sensors. The are about 4" long and 1.5" in diameter with a 2 pin connector on the end.

Your crank sensor is in the pass side of the tranny bellhousing. It's the little thing sticking up in the lower left corner of this pic. I don't have a pic from the outside.

Are you sure it's not the vanos seals and running around the block and down near the mount?

I have minor oil leak that runs down drivers side on to the power steering pump. I think this is the vanos seal that appear to be leaking (lots of dirty oil around them) but hard to see with pipes and stuff in that area. There ~$6 each and two bolts to change so a good starting point.

A side comment would be are you sure its engine oil? Powerstering fluid is common leak on that side of the engine bay. The mounts are also oil filled so the could have just have gone and be leaking their oil.

His oil lines from the remote oil filter canister go to that side of the block.

Well, it's too late now, but pressure-washing a modern engine is a big no-no. You have no doubt forced water into several electrical connectors, that will begin a corrosive process that will cause a plague of electrical malfunctions for years.

Na it's not the vanos seals its nice and dry in the front of the motor.

And no I didn't pressure wash the engine. And it's not ps fluid I replaced all that already.

Jimlev may be right if I shove my hand up I can feel the wetness right in that area.

Is this going to be an easy job or should I leave it be.

I'm looking into building a turbo engine setup. But I do love driving this car so I don't want to take it off the road just yet till winter.

Circuit B is exhaust. It's a 5 min job and only requires a 5mm allen key. It's right under the t-stat behind the expansion tank.
