jay-d Posted August 11, 2013 Share Posted August 11, 2013 I'm eliminating all vacuum leaks using a smoke machine (I've hooked up the smoke machine to the BOV vacuum line that goes to the engine, the little tiny one without the clamp) and I've come across this little piece of metal. It's under the intake manifold, on the driver side. Here's a reference picture and a zoomed in picture. What is this metal pipe? It's smoking like crazy and covered in oil!

jay-d Posted August 11, 2013 Author Share Posted August 11, 2013 Upon further inspection.. it doesn't look like it's coming from that pipe. It looks like it's coming from above the pipe, but underneath the intake manifold. These images are from leaning over the driver side fender.

Code Posted August 11, 2013 Share Posted August 11, 2013 Intake manifold gaskets can leak from the factory. It has been seen before on the 4th gen platform. "Striving to better, oft we mar what's well." - Bill Shakespeare - car modder Link to comment Share on other sites More sharing options...
jay-d Posted August 11, 2013 Author Share Posted August 11, 2013 Yes, but this is coming from the underside.. not where the intake seats with the TGV.. Link to comment Share on other sites More sharing options...
DarkSideGT Posted August 12, 2013 Share Posted August 12, 2013 did you check the throttle body to inter cooler hose? Link to comment Share on other sites More sharing options...
jay-d Posted August 12, 2013 Author Share Posted August 12, 2013 did you check the throttle body to inter cooler hose? I believe this is it.. I will have a look tonight. With the new turbo and the bulletproof mod on my TMIC, I had to wiggle and move it around a lot to get it all to line up. I think I might have moved the TB hose.. makes complete sense! Didn't even think of that, thanks! Link to comment Share on other sites More sharing options...
