I have an '01 v70 t5 w/77k miles, and a AT that hasn't failed(yet, hehehe)<br>today i checked the spark plugs to see if any of them were fouled, as I have been driving on a bad Mass Air Flow sensor for about 2-3k miles now. <p>What I found when disconnecting the air charge pipe was disgusting black sticky tar-like goo that seemed to have oozed along the bottom of the pipe and down into the connecting hose that connects the plastic over-the-engine pipe into the intercooler. <p>What should I do? replace the air charge plumbing and see if more oozes down? I want to say that because this ooze was so thick, that its not accumulating very quickly. My oil consumtion is near-zero in-between oil changes.<p>Any ideas or suspicions? I would appreciate anything, voice even your gut feelings, justified or not! Thanks

Re: Goop in Turbo charge pipe (skindiving)

What you are experiencing or seeing is refered to as "Blow By" all turbochargers do it to some extent... You seem to be one of the more fortunate ones that have a minimal amount. Vovlo has a catch can design that trys to put the oil back in the engine successful for the most part but a good catch can help some cars... Nothing to worry about... Just clean it out and reinstall... The best thing you can do is ensure clean oil and not pushing the car hard before you shut down the engine... This can cause a situation refered to as coking, which is oil that cooks in the turbo cause the oil is no longer circulating... So in short you are good to go. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">
