So a while back there was a lot of talk on here about the Intake Camshaft Sensor on our engines leaking oil. I know a lot of people, myself included, got the sensor replaced under warranty. I know a lot of people's have begun leaking again. I checked mine today and it's as wet, if not more, than it originally was with oil.

Does anybody know if GM has come out with a permanent fix for this yet? Anybody on here a GM tech with some better info? Im planning on bringing mine back into my dealer just so its on record that its still a problem. Its really saturated with oil and thats ridiculous for a new car.

 

i had mine replacedin like the early part of april but when it was done my friend who just happens to be a tech put a little RTV on it...so far so good

 

im a tech at gm. i also have the cobalt t/c. mine was leaking as well but its not the sensor thats leaking. its the gasket and seal from the high pressure fuel pump. replaced mine which was on back order by the way and havnt had a problem since. that was about 3000 miles ago

 

So what did you replace? The gasket and seal? Supposedly my dealer replaced the sensor....its been probably 3-4mos and now its leaking again.

 

the high pressure fuel pump is rite above the camshaft sensor. where that bolts in is a gasket and inside is like an O-ring seal. thats what you need to tell your dealer to replace. it leaks from there down to the camshaft sensor

 

i am always checking this and no GM has yet to send us any info on the other 3 i have replaced

 

i need some pics, where do u look for the fuel pump and cam sensor, i wanna check mine. tried to find it once, have no idea where it is

 

So youre saying its actually the fuel pump gasket leaking?

 

Can we get a part number?

 

No there is no news from GM, and YES it is the Intake Cam Position sensor on probably 95% of cars, RTV fixes it.

 

My high pressre fuel pump gasket was leaking too. I used black RTV on it and it no longer leaks. I also did my cam sensor too. Finally, no more oil leaks on this thing.
