boost leak but where

[windy]

I've noticed a boost leak in my '04.5for about a month. It's getting worse and sounds like it is commingle from the passenger side of the truck. But how do I find out where it is coming from?

Have you checked your boots? There is a link around here somewhere that shows you how to build your own test setup. Maybe AH64ID will drop by and give a hand on the subject.

I would check all your boots and connections. It's an 04.5 so it shouldn't have a plastic end-tanked intercooler, but take a peek to be 100% sure. To build your own tester you need to put a plug on the turbo intake that has a schrader valve in it so you can pressurize the system. Then get out the windex and find the leak.

Another way... Build a boost cap and pressurize the system...

How much pressure should I put to the system?

[jlwelding]

I wouldnt go over 20lbs, but thats me. You shouldnt need but a little pressure 10-15. Your turbo pushes 20+.

I got the system to around 15 psi and found a leak around the boot at intake side of the inter cooler so I tightened up the clamp. But I still have a leak some where and I can't find it. Anyone got any more suggestions.

Isn't this also a "round-a-bout" way to check the condition of the pistons rings and valve seats??? Afterall, that's the area the "air" is supposed to go anyway!!!

Not really going to be able to check valves and seats with this... Because only one cylinder maybe open for air pressure. As for pressure I only used 5-6 PSI because the clamp wasn't strong enough.
