Need help fast.
Need help fast. Ok Readers Digest version.. New motor almost 3k miles. Runs great Park it one night next day oil leak???? Well Look at valve covers..No leak look around and oil is all over front of motor and on Engine Covers etc... So I pull Intake manifold off and sure enough Puddle of oil under manifold on top off valley cover, but car still runs strong and doesnt seem to have an power issues or anything. So I pull valley cover and one of the seal for the knock sensors is broken could this be where all the oil is coming from? There is oil on inside of intake manifold and intake ports on heads as well? Any one have this happen before any ideas??
It sounds like you found the problem to me. Not sure if there is a seal + sensor, or if it is built into the sensor itself, but you should get it replaced. Was it coming out all around the manifold? Leaking anywhere else?
I know there is a bunch of oil and its making a mess. I just can't see all that oil coming from that one place. Im hoping its not coming from a cylinder. It would seem to me though that the car would run different and the car would be constantly smoking from the tail pipes which it is not.
You can get the seal by itself. The lower seal (the one that goes around the knock sensors) is PN 12558177, THe upper seal isn't sold by itelf but both come withthe knock sensor wire that is PN 15372170. These part numbers are the same for the LS1 & LS6 Valley cover area. I've heard that you should seal the upper seal/covers with permatex. I did, but Im not running yet.
