Hey guys i have some sort of leak around my turbo or under it, i can't seem to figure out what it is. I've changed the downpipe gasket and the uppipe also and it's still there. Could it be that my downpipe is cracked? i've also noticed a little bit of power lost and the car spools up later than it normally does, not 100% sure though could be in my head? Do you guys have an idea of what might be the problem?

Thank you

 

Did you change both gaskets on the uppipe?

 

Spray some water with soap it it on all exhaust connections. Try to plug the back of your exhaust with something too.

 

yeah i did, i didn't take the whole uppipe off though, i just wiggled it to slide off the gasket, so i wasn't able to inspect the whole up pipe.

 

i shall try that

 

have you guys ever heard anyone cracking their up pipe? i found out that i'm missing the 2 brackets that hold my turbo.

 

Brackets that hold your turbo?

Are you running an aftermarket or stock uppipe?

 

i'm running an aftermarket, sorry it's the brackets that mount to the uppipe and frame of the car?

 

Hmm I guess mine doesn't have that bracket.

Yes it's possible to crack an uppipe, mine was at the welds.

 

whats mods do you have?

 

yeah i'm just gonna buy a new uppipe and have it installed

 

vf34 and bolt ons

 

When you hit the gas and build boost, what does the leak sound like?

loud high pitch screeching = pre-turbo
sounds much like your normal exhaust, only louder, maybe deeper = post-turbo

screeching is often (in order of likelihood):
- manifold to uppipe (by far the most likely)
- head to manifold
- aftermarket uppipe to turbo flange warped & needs ground flat.

 

+1 to this answer.

Also when my uppipe was leaking from the gaskets it was popping like crazy under the hood..

 

yeah mine pops a lot too!
