Vac Leak.. Where though??

[99GsxMD]

I have a boost leak tester but i am unsure of how to use it. Thats what i have been reading about on here, and thats what some people say to do. I am unsure how to do a boost leak test though, i have never done one. I need some advice on how to do it. Also i need any idea's of what else and where else thise vac leak could be. I did just put a new ets 10.5" race intercooler on it, i am guessing that it could be coming from somewhere within the new piping that i put on. Any idea's would be great!

clamp the test the inlet of the turbo and push 15psi to it

it that easy?

Yep pretty much. Just lisen for hissing sounds. One thing that I use for vacuum leaks is a arificial smoke they use to test fire alarms and systems. You put some in your intake and it goes through the turbo and seeps out where any leaks are. saves a ton of time.

what about soap and water?

Yeah a homemade intake leak tester works awesome for identifying leaks and you may find some you'd otherwise never have noticed Home Depot will have the pieces you need to make one. Get a rubber plumbing connector in the diameter of the turbo inlet with the clamps on both ends. Find a plastic plumbing endcap to clamp into one end. Drill and tap a bicycle tire valve stem into the plastic endcap and you're done. Attach one end to the turbo inlet with the intake system out of the way, and connect the other to an air compressor. Have someone watch your boost gauge while you listen in the engine bay. Leaks will be blatantly obvious so you won't need to strain to hear them

Or, while it's running, chase the lines with WD-40. When the engine speeds up, there's your leak.

What do you mean by chasing the lines with wd-40. What is the proces i have to go through?

 

[5spdFTW]

im guessing he means just coat your lines with wd40. whent he wd40 enters the leak the flammable spray will act like adding more fuel to the engine and speed it up.

im having some idling probs also on a 95 eagle n/t, i know of atleast one disconnected line and im looking for a way to test for more leaks, would the above method (with the air compressor) work for non-turbo cars? or is there a better/easier way to test for n/t engines? what is this smoke test business?? how do i do that?

didnt mean to jack your thread.

Soapy water's always worked for me. If your running more than 15lbs. of boost then I'd test it at whatever your running for boost. While your testing just search around for hissing sounds as was stated. Make sure to check where the injectors go into the head. Ive had that lower seal leak a couple times on me.

 

[Aphix]

As stated above the injector seals are a common leak. But since you did just put on an intercooler I would really check your hoses. It doesn't take much for a leak. You best bet is to go around and tighten all the clamps, also you can find ways to make a leak down tester in the tech articles.

Do a proper boost leak test. These instructions helped me a lot - http://www.dsmtuners.com/forums/art...-boost-leak-test-how-boostpro-net-tester.html
