How to test boost boots for leaks

[silentsoul]

Alright, long story short. I installed a custom tune and was having trouble with it shifting right. The pickup was running around 30 psi of boost for a full minute or so. I heard a loud wooshing sound under the hood, and now have trouble building boost. Is there any way to test the boost boots/intercooler tubes? Anybody have any other ideas?

no need to test, take a look at them, it shouldn't be too hard to find. you could have blown your CAC too, when that happens you'll find the seal hanging out from a side of the tank

I looked at them, and they look ok, I was just wondering if it was possible for them to get a small split that only shows up with pressure applied to the boot. By CAC do you mean the intercooler? What do you mean by the seal hanging out of the tank?

yes the intercooler. the core is aluminum and the end tanks (sides) are plastic. Sometimes the rubber gasket that sandwich the tanks to the core blow out causing a boost leak. Usually you can find the gasket hanging out somewhere.

what year is your truck? if it's an 05+ and it has a black plastic cold side duct those can fail at the bottom bellows. it would be very hard to see without removing the air filter assembly

Mine is a 2006. Cool thanks for the advice. I will pull the air filter assembly tomorrow. Is it going to be the connection made onto the intercooler, or the rubber bellows in bwtween?

He's talking about replacing the black plastic duct with a factory metal piece.

6C3Z-6C640-AA is the part number. Sunrise ford is apparently a sponsor on here.

Under the air filter assembly is the cold side connection to the intercooler. You'll see the accordian on black cac tube straight off the intercooler. you may have have someone run the engine while you feel and listen for leaks.

Thanks for all of the help guys, it is a blown plastic cac tube, right in the bellows part!

Order that part number I posted. It will be a metal duct with 2 rubber boots, similar to the hot side cac tube. I don't like that black tube they put on these trucks.
