Peter, you make it sound so easy. You should come over and help. The boost leak tester is on the car. Car was running fine after it was all assembled again. He had a boost leak which was the TB before. I fixed and the car was boost leak tested to 20psi fine. Car made a couple pulls at 25psi and all was fine except maybe the HG (pushed coolant on the last pull). I made a BOV recirc tube by soldering some copper elbows together (
) , lowered the boost a little, and took it for a spin to see what it was at. Hoping for ~23 psi, all I could build was around 5 and the car started missing. My air compressor can build only 5psi until it stops building on the boost gauge. The last 5psi does not drain quickly from the system though. Seems as if a gasket may be blown out part way. If any of you haven't checked, it is quite hard to use soap and water on an intake manifold. That is about where the sound is coming from, cannot feel anything however. Strange how one day the car is fine, the other day it has a boost leak and runs like shit. Vaccum is around 14-15 at idle. Nothing but problems on this car...
