Boost/Hissing Leak
Ok, let me start from the top. Last night me and a couple buddies turned up my truck, shaved the fuel plate modified the "foot" in the AFC housing and cranked the star wheel. When we were buttoning it back up, the gasket that sits on the grid heater between the heater and the air horn broke, so we put a dab of silicone on the crack and buttoned it up. Truck was fine, then today coming home on the highway, I noticed an "air" noise. I first thought I had the heat on, and I didn't want it on, so I reached for the HVAC controls to shut it off and saw that it was off. Then I gave it some more throttle and the noise got louder as the RPMS climbed. The noise sounds JUST like the heat or air coming through the defrost vent. I thought it was the air horn, so I took it off, and make a brand new gasket with RTV, buttoned it up, waited and hour for the silicone to dry and fired it up. However, still have the same . Where else should I check for boost leaks or what else could be the problem here....?:humm:
---AutoMerged DoublePost--- Oh, I wanted to add. After I sealed it, the first time I started it, the truck started ok, and then the rpms dropped and it studdered a bit for a few seconds and they came back up and everything seemed to be ok...could that be from teh silicone that ran over the edge getting sucked in...? |
check all your intercooler hoses probably a clamp off seat or something happens a lot especially since you had the horn off

I could be wrong but i dont think its the gasket it needs to be there for sure but i dont think a cracked gasket would make it run bad how bout getting some gasket material from parts store and make your own and see if that helps
