GTTuner Posted January 24, 2011 Share Posted January 24, 2011 Hey Guys, Working on a customers car yesterday, replaced a dead oxygen sensor, after replacement STFT was +25% at idle. Removed the top mount and found it leaking at the coupler. Fixed that, still getting +25%. Fixed another post MAF leak along the backside of the intake. Got trims down a couple of percent but I suspect a split or damaged intake tube. Sets a bank 1 lean code after idling a couple of minutes. The MAF scaling seems OK from what I could see (K&N intake). Question is this inlet fits like crap, is it common for these to leak and where? The connection to the turbo looks OK, when I spray carb cleaner down in that area (which you cannot see unless you disassemble) the trims drop down to normal. A leak test was done, I found the first leak quickly. I suspect the hose that goes up to the BOV is leaking under the intake but I cannot get to it easily and another leak test was not showing anything. I told him to get the old intake tube before we rip off the intake and top mount. Any input to this? Link to comment Share on other sites More sharing options...
Dirtrace95 Posted January 24, 2011 Share Posted January 24, 2011 I thought the perrin turbo inlet was supposed be better fitting than others .... Link to comment Share on other sites More sharing options...

Even if there are no issues, which there always are, they do not provide any benefit - all pain, no gain.

GTTuner Posted January 24, 2011 Author Share Posted January 24, 2011 Yeah, it fits in there like a ten pound bag of crap in a five pound container. Link to comment Share on other sites More sharing options...

kirbwrx Posted January 24, 2011 Share Posted January 24, 2011 I only "like" them because my stock one is ripped and I dont feel like removing the manifold to replace with a stock one. Link to comment Share on other sites More sharing options...
underpowerd Posted January 24, 2011 Share Posted January 24, 2011 ^ +1 -- the stock one is a bad joke. GTT, i don't think the bov area would rip though all those plys under any normal circumstances, but a leak is certainly a possibility if the original installer didn't really do it up for keeps the first go-around. personally, i've never had any issues with my inet at all, but i really did up those clamps/hoses/fittings and made certain to angle the gear bolts for occasional tightening access, to make sure i'd never have to get all the way in there again. is the car using the stock bpv hose? it fits the aluminum fitting supplied with the inlet like shit (hose is too small for it). if the installer got fed up, and only lipped it on before clamping, that's likely your culprit. if you can't get in there with an extension to the head of that worm gear to tighten it to a resolve, i'm afraid the whole lot may have to come out to be done up correctly an alternative might be to use a different bpv hose, and try to get it onto the fitting without inlet removal. best luck.

GTTuner Posted January 25, 2011 Author Share Posted January 25, 2011 ^^^ That area is exactly where I suspect the leak is. It has the stock BOV hose in there and I saw the cluster of clamps in the area. Thanks man. Link to comment Share on other sites More sharing options...
GTTuner Posted September 26, 2011 Author Share Posted September 26, 2011 Thread bump. I guess Perrin redesigned the inlet tube? I installed one yesterday and it fits nice! Link to comment Share on other sites More sharing options...
