Cam Sensor Leaking.

Recommended Posts

I took my 1999 C2 down for it's Tech Inspection for an up coming PCA event this evening, The tech guy placed the car on the rack and inspected the underside of the vehicle, later he called me over to inform me I had a small leak around the base of the cam sensor, he didn't think it was that big of a deal and passed the car anyway. I also spotted a leak around the base of the oil pan in the corner area along the bottom.

However being the Porsche fanatic as we all are, all problems must be immediately addressed.

So my question to the board is

1. Has anyone removed the Cam-sensor ,

2. Is this a big job or something to do at the next oil change along with the Pan gasket? I guess my actual question should be

3. how hard is it to remove the Cam-sensor?

I think you are referring to the cam solenoid cover. The cam sensor is a small sensor (about 3/4") on the opposite side of where the solenoid is. I have not changed the solenoid but it is common that there is a little oil around it's cover. Mine has sweated (not enough to drip) since day 1. Both banks.

would you have a diagram of this sensor cover on the left side of my 3.4 engine. the leak is getting worse, a 12 inch puddle of oil has developed on the floor of the garage. Has anyone had this issue?

Please help

I had the cam solenoid cover seals done by the dealer. it will probably remain leaking I am told although less so because evidently there is another seal inside which is more difficult and more expensive to get to- this is what I was told at least. I had that oilpan leak also and replaced the oilpan as well with the new revised one. You might consider that as I was told because I ehem bottomed it a couple of times that it would affect the sealing- Good luck, don't want to discourage you but that is what I have gathered from my $$$ experiences-

The solenoid cover seems to be the culprit, Its not leaking heavy when I get under the car I dont see any drop's forming. I can see it looks oily in the area around the solenoid cover. Perhaps I'll get a drip pan and be done with it. All car's leak oil, I havent seen one yet that was totaly oil leak free.

Any pics of the cam solenoid cover?

Actually, I think porsche calls it the Cam actuator. There are 2 and each are secured to the engine with 2 10 mm bolts and each has a wire coming out of them that is about 12 inches in length and connects to a connector coming of the main wire harness. Bank 1's is on side of the engine closest to the back seat (driver's side) at the level of the cylinders and bank 2's is at the same level buy at the back of the engine closest to the bumper.

I have not had the guts to remove the solenoid due to the fact that I am unsure is something will be disturbed upon it removal. It is a $180 part.
