Im getting a really loud air leak sound. It disappears when I remove the pipe from the top left part of the engine I cant figure out what its called, but its near the airbox. The only thing I can think of was that maybe the seafoam has something to do with it Or the nm discharge pipe that was recently installed.

I pulled codes something on the line of.
P1497
P0100
P113B

Im trying to figure out if these are all related. I havent found anything on the forums with someone experiencing all three codes.

Any ideas?

 

Is it the PCV hose?f yes it may be cracked. I recently found that in mine.

 

I just blocked off the 2nd Pcv valve and added and oilcatch can but I still seem to be getting the cel!. Dealer says its cause " unmetered air" but I said that can't because other people have installed these without problems.

 

post a picture of the pipe you're talking about. it will make it a lot easier for us to tell you what it is.

 

It was that rear pcv valve that connects to the manifold or whatever. I blocked it with audi caps. The hissing has been fixed, but I still keeping pulling CEL's, as soon as the car starts so im at a loss, no idea what it is. Ive checked the forge diverter for leaks nothing. I can only guess its the nm discharge pipe I just recently put on.
