how to smoke test a compression leak

neat youtube video, pretty easy to follow, they do it on a truck, but the theory should be the same (mods yes no?)

Thats just a genious idea, lets you know right away where the issue lies.

For you, the process is going to be slightly different. You'd be hooking it up to the intake, and checking around the engine bay to see where any smoke is coming out of any piping.

yup for sure, i just found this video while looking for different ones, seemed postworthy
once the temp here gets above 0C again i'll rent the smoke machine

Are you trying to track down a vacuum leak?

i've got a boost leak
i posted this video for people looking for a different kind of leak, my compression is good

Well dude, awesome video and good luck finding your leak!

thanks, once it warms out outside a bit in a few days, maybe next weekend, i'll rent that smoke machine and maybe take a bunch of pics to go with it and post up a how-to .. assuming it works *lol* i can barely hold enough pressure to fire the BOVs
(prays that it's not a turbo gasket)
i've had a hardpipe coupler pop on me once (the band wasn't tightened) so i know what it feels like to have no pressure at all and zero boost, .. i'm still boosting, i can hear the turbos spooling, just not quite 100% ya know? gut feeling
