lol waste of time imo

a thorough search while listening to the engine (while its running obviously) has never failed for me and iv had a few

but its true that some can be hidden so well that it takes a while

im thinking i might have to check the breather next to the DV as its really oily - i know there supposed to be oil but mine seems quite bad!!

That's a pretty cool idea.
You'd think you'd hear 7psi escaping somewhere on the road though wouldn't you.
The trouble with checking for leaks when the cars sat still is it's not under load, the pressure isn't in the system.
I'd like to try that on mine just to double check I have no leak anywhere but I don't have an air compressor anyway

ive got one!!!! well not mine but the old man wouldnt mind me using it!

i think my hearing is buggered as i never heard my first boost leak and that was by the n112 valve! -

slightly off topic - the metal pipe the TIP goes on to, should this have a clip on it? and how easily should the TIp come off? as i tried removing mine and it seemed a little tough and had no clip

Now that is bad! When mine went it was so loud

Yes it does have a clip. I took the whole lot out in one go. I didn't bother separating the metal and the rubber parts.

excuse my naiveness (if thats a word) - but from the rubber intake, it goes the the metal cylinder - where does it go after that? and is it a case of removing it by hand -

Im looking to get the samco intake hose, does this go on the metal cylinder ?

cheers

the turbo mate

there is a small bolt holding the metal Tip onto the turbo's inlet

it doesn't require much because in essence the turbo is sucking through the TIP

if you purchased a new silicon TIP such as the forge part, it would replace the metal end and its rubber intake hose

That idea is pretty good. Alot of the American guys on Vortex use that technique - Helps to find leaks that only appear under max boost (like over 15psi) as you can't replicate that kind of pressure whilst revving it in neutral

imght had to purchase me TIP then...has to be in red though! after reading the link above, the guy had a leak by the breather so process of elimination
