05' Plastic intercooler... possible leak

[AMassaro]

After installing a 2micron fuel filter setup in the engine compartment, I started the truck to check for leaks. All was good, however I'm hearing what sounds like an air leak. I'm pretty sure I never heard this before and it seems to be coming from the drivers side front radiator area. I've also noticed that producing my normal 42lbs of boost is not happening as of late. I'm thinking I may have a small leak somewhere. I went over all the hoses and snugged them up.



Are there any particular ways I can check for a leak? I was thinking about a spray bottle with some soapy water, looking for bubbles. Any opinions?

Air leak

I guess it is possible to hear a leak at idle. You will definitely know when driving. If you are hitting 42psi and there is a leak, it will be really loud. I replaced my intercooler and had a leak. It make an horrible squeal at about 8psi and up. I had made a fitting to clamp into the tube that comes off of the turbo and put about 5psi on it from an air compressor. I then went around it with soapy water to find the leak. It ended up being the rubber boot between the cooler and tubing. I could not hear the leak at idle with the engine running.

Once I found it, it was easy to fix.

I don't know if what I'm hearing is in fact a leak. Thanks for the replies anyway...
