Loud Hissing Noise

[DCREDNECK1]

I have started noticing a hissing noise that is higher pitched than the turbo and has a consistant increase while turbo is spooling, any thoughts?

I know the answero this one. I would venture to guess that you have a cracked flex tube and the reason that I know this is because I have had it happen to me. The fun part is going to be finding out which one is cracked.

Wow granny, your so smart.

Terri is one smart girl.. Terri is correct, you have a cracked turbo up pipe. they blow in the flex section. I have replaced my passanger side twice and my driver side is blown now. I am going to replace this time with a crack proof aftermarket pipe from liberator performance.

Not too shabby for an old lady! LOL That noise can be scary the first time you hear it! I have fixed that problem now. There are a couple of vendors out there who have products to help in this area.

Thanks for the help, i'll have a look in the morning. Anyone with a link to a good aftermarket distributor?

We have an nice Solid up pipe that blocks off the Exhaust gases from entering the EGR cooler, (AKA EGR BLOCKOFF) which is an added benefit to the fact that the flex section is removed from that pipe. It will fix your problems. You can find more info here:

For the record, I just got my truck back from the Ford House on Wed., take a guess what for.............

EGR Cooler and Oil Cooler ($2900), luckly no head gaskets. They also replaced the EGR Valve due to carbon build up. The only reason for not deleting the EGR then was the dealer met me 1/2 way on the cost of the repairs. I've only owned the truck for 1 month, but it's out of warranty by 2 months come to find out.

Sounds like a fantastic dealership! Do you mind sharing who it was, and where?
