Taking the TB off to be rebuilt and could not help but notice that the under side is covered with oily dirt. 20,000 miles since I put it all together, but this area has, by far, the worst build up.
The boot seems pretty stiff but no obvious cracks of holes. 1. I assume the oil is coming from the oil tower filler neck. But why would it blow out with air sucking in? 1st thought the stiff boot did not make a good seal and this is my vacuum leak. But again shouldn't it suck in? But the btm clamp screw on the boot was very tight. 2. is this normal? 3. are the "S" boots available new? |

PCV valve not functioning correctly? Where would that be? I don't think i have one. A 1" pipe is in the funnel. That leads to the btm of the intake boot. The funnel tower is open to the case and the intake is open to the pipe. Not sure on the 1.8. But it would seem if you are pulling directly from the case with no filter or valve you would have to be pulling oil out. |

I assume when the engine is off the mist stops flowing, cools off and settles til the next engine start. In the mean time i believe it had found a way out. I gotta get a better seal between the TB and the intake boot. |
