Well, I know a lot of people will say "it's not necessary". But as a dumb guy like me, I felt necessary when I was searching for which "vac line" I should use for 1.8T engine. <p>1. remove the L-shaped hose (orange circle)<br> <IMG SRC="http://lh3.ggpht.com/_PVISQxRxUoc/S52fWLjJWKI/AAAAAAAADtI/pWC15pJveeI/2010-03-14%2009.54.23.jpg" BORDER="0"><p>2. connect a 5/16'' hose (I stole from my lab). I cut one end of the hose with slope, so that I can easily prevent the opening from completely submerging under the liquid. <br> <IMG SRC="http://lh4.ggpht.com/_PVISQxRxUoc/S52fWq9ASJI/AAAAAAAADtM/1qNlgrOoB_w/2010-03-14%2010.13.16.jpg" BORDER="0"> <p>3. Start engine and siphon<br>4. Shut engine off and wait for 5 min<br>5. Start engine and rev it to high rpm<br><IMG SRC="http://lh6.ggpht.com/_PVISQxRxUoc/S52fXkdeMaI/AAAAAAAADtU/uAQtn6ckHA8/2010-03-14%2010.17.19.jpg" BORDER="0"><p>Really no need to take a photo of the smoke. Today is very windy, so the smoke was blown away before the neighbors could discover. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> <p><br>One problem and question:<p>I saw smoke coming from behind the engine, a leak at the exhaust manifold?
