I have no idea where it is coming from! Noticed it when I was on the Dyno a couple weeks ago, saw the drip spot on the floor under my car when we were done with my 5th pull. But I could not see where it was coming from. The drip mark was on the passenger side of the engine bay, and seemed to be directly under the farthest side of the bellhousing closest to the passanger side of the car. Any ideas?

 

Have the heads been off the car?
I was having a strange leak after my heads had been sent off. Come to find out the plug on the side of the head was backing out and leaking. Pulled the plug out (it screws in/out), put sealant on the threads and put it back in, no more leaks!!

It is where the temp sensor would go if the Head was on the opposite side....

 

The heads have never been off the car, nor the intake or anything like that, the only thing that has ever been taken off the motor was the fuel rails. I broke the shrader valve off my origional fuel rails , so I had to replace them, also they came off for my injector swap.

 

I would check it. I thought it was a head gasket but without the classic signs. and right before pulling the head I found it...the EWP could push it out just sitting there cold.

I heard it hissing one day and then began seeing the drops. I put it on stands and it continued to leak for a long time. Until it leaked out of the head below the plug. Once i turned on the EWP it would fill the head up and start leaking....

 

I'll check that, any other ideas?
