heiche Posted June 13, 2014 Share Posted June 13, 2014 ^ this. probably the turbo inlet hose. yes, it's a pain to replace you could try to tighten the clamp, but often the part of the hose that clamps to the turbo deteriorates and tears.

ssbtech Posted June 13, 2014 Author Share Posted June 13, 2014 Do you happen to know if that air duct is similar to the TB hose in that it has those silicone rings on the end that can be removed or does the whole duct have to be replaced? I don't suppose it can simply be loosened and slid forward without lifting the intake manifold? I don't mind lifting the manifold, I just don't want to be mucking about with the fuel lines that are attached to it Link to comment Share on other sites More sharing options...

Scubaru03 Posted June 13, 2014 Share Posted June 13, 2014 There wasn't one of those rings on my inlet when swapped it. I had similar issue and swapped my inlet thinking it was my problem but ended up being the intake gaskets. Those reading are looking a lot better. I know being closest to 0 is the goal but I've heard people say +5/-5 is healthy. Have you cleaned your maf sensor? Link to comment Share on other sites More sharing options...
ssbtech Posted June 13, 2014 Author Share Posted June 13, 2014 Yeh, I cleaned it a few weeks ago. I wonder what's causing that little bit of knock there... Link to comment Share on other sites More sharing options...
heiche Posted June 14, 2014 Share Posted June 14, 2014 Right - the turbo inlet hose is effectively one piece (no gaskets). When you did your most recent boost test that successfully held pressure, was the turbo inlet hose included in the test? Where did you block off the intake? The orange intake manifold gaskets can definitely be a source of vac/boost leaks too. However, they usually are only a problem when the engine is cold, and once it warms up they seal ok.

ssbtech Posted June 14, 2014 Author Share Posted June 14, 2014 I stuck a bottle right into the tube where it attaches to the air box. I'll have to see if they used new intake manifold gaskets when the engine was reassembled in late 2012 after a valve job. Link to comment Share on other sites More sharing options...
heiche Posted June 14, 2014 Share Posted June 14, 2014 ok. it's possible that there is no vac leak if your last test held pressure the way you described. 5% isn't *that* much of a correction really.
