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.
1. remove the L-shaped hose (orange circle)
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.
3. Start engine and siphon
4. Shut engine off and wait for 5 min
5. Start engine and rev it to high rpm
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.
One problem and question:
I saw smoke coming from behind the engine, a leak at the exhaust manifold?
