How Do I Find A Hot Side Leak?

[MrStabby]

EDIT: Hot side is not the right terminology - i mean post compressor

Symptoms;

- suddenly no boost after a track lap

- stalling after throttle blip or pulling up at the lights

No smoke so I assume that means its not a turbo (they're 5000km old rebuilds), so i'm looking for a leak.

I've checked the four rubber pipes and they all look fine. I took off the two pipes in the engine bay to check them, they looked ok, replaced them but no change. So what now?

can you hear the exhaust leaking anywhere? or are you just guessing its a hot side leak?

Hot side leak means it leaking after the engine on the exhaust side so you should be able to hear the leak.

to me it sounds like there is a leak on the cold side / intercooler pipes etc etc

try spraying some brake cleaner or start ya bastard or something around where you think it might be leaking

I have no idea where it is, so do i just spray along the whole length until i hear the idle lift? I think i have a can or aerostart somewhere which i assume is similar stuff.

yer thats what i'd do, not sure what the idle do as i've only run a car solely on brake cleaner, never sprayed it in with the car running off fuel.

You could try blocking up the tailpipe for a second or two when its running. Becomes pretty clear!

blocking tail pipe, or loading it up in st with the handbreak

i had get mine on a dyno to be able to locate it....
