Hey guys, I just replaced all 6 of my valve cover gaskets and when I started it to make sure everything was kosher I noticed a hissing sound coming from what sounds like under the injection pump. I don't think it's coming from the valve covers because I put my head near them and couldn't hear it. The sound pulsates too with the chug of the engine.

Hopefully this makes sense, if not just let me know and I'll try to clarify.

 

maybe in the vacuum pump it's under the injection pump

 

Lower inter cooler boot loose or leaking.

 

ok cool, I'll check those 2 things when I get home. Thanks guys!

 

Find something out??

 

What's the good word??
