Boost leak = Loose Couper

Check all pipe connections

801nismo104 · 04-13-2013, 10:21 PM

should be simple. you have a leak somewhere

irun240sx · 04-13-2013, 10:26 PM

i think the couplers should be fine.. they are all as tight as they can go. anything else?

Recheck all your work. You have to have a leak somewhere. Make sure nothing is open and everything is hooked up and tight.

Yea 'tight' doesn't mean they don't leak. Build a boost leak tester and test it. Search how to do it.

I got a leaky coupler that I can't get to seal. It's fucking garbage.

SOo, i'm pretty sure its has something to do with the wastegate... i pulled the line connected to the Wastegate and was able to get boost but i didnt attempt to hit my full boost because i read that it could have negative effects on the engine. what do i do now?

irun240sx · 04-16-2013, 03:54 PM

ALSO, when i hit 3100 rpms or above, there's a loud whoosing sound (someone said its my wastegate staying open?) should i just replace my wastegate? or can i do something about it?

Hey,

irun240sx, where are you getting your vacuum pressure from for the wastegate? On the hot side pipe?

irun240sx · 04-16-2013, 06:29 PM

its connected to a line running to my brake booster
