Well a funny thing happened this morning... I started my truck, got out to throw some trash away, and while i was walking back to my truck, it made the exact sound, pretty loud too, of a blow off valve, just the perfect little pshhewww sound. No idea what it was, but it didnt idle up or down, just kept on like nothing happened, kinda weird, any ideas?

 

HI!... Your truck's trying to give you a hint! Hurry up and get that TURBO set-up on!

 

lol I thought the same thing! Its driving me crazy!

 

I'll bet your AC doesn't work anymore......

Steve

 

Yeah that's what happens when you forget to replace the summer air in your tires with winter air.

I thought everybody new that

The only things I can think of,

AC compressor or line leak, radiator cap leak, or some vaccum part leaking

 

Hi.

Was there a smell? Check your shorts

My vote's on the A/C ...

 

well the A/C works just fine...

 

It is pretty cold outside afterall... you sure?

 

yeah, its 40* here today, i turned the vent on, then turned the a/c on max, it bogged down, then the air got really cold

 

My truck makes that type of noise when I am driving and it shifts between first and second. It is coming from the driver's side. I think it is my EGR gasket leaking, since that is the last thing I changed on my truck and I used some of that gasket maker stuff instead of just buying a gasket.

 

Maybe your truck had gas.

 

yeah mine does the same thing.... if you let off the pedal at the right moment after WOT when it shifts the fan belt will squal... boost blow off baby.. LOL

 

lol, mine did that after I put the shift kit in, so i put a gatorback belt on, and no more squeal...

 

Any neighbors cat's missing

Onetime a cat was up in the radiator and when the truck started it made one hell of a noise. The cat made it out alive but it was shaved in places I've never seen before

 

lol wasnt a cat...
