So incredibly frustrated

Got a new CPU from Mazdatrix
Got the engine to manifold gasket replaced
Got the mainifold to turbo gasket replaced
Have the efan wired properly...though I may go back and put larger gauge wires in

Started the car up tonight and it's got a horrible vacuum leak. It whistles and stalls. I was too worn out from helping a coworker with a surveillance system install to mess with it. Guess I'll start taking things apart tomorrow and find the leak.

If the leak is that bad I wouldnt take things apart. Instead, pull the AFM and fab up a cap/plug with PVC fittings from HD or Lowes. Then pressurize the system with your compressor.

Here's a vid we shot of our test setup.

It includes an TMIC bypass pipe so we could get at all the potential leakpoints in the rat's nest and intake manifolds.

We also made this vid showing how we used dry ice in a watering can to make seeing the source of a leak easier to find. If you smoke that'll work too. Unless you have a pulsation damper leak in which case you might blow up!

Hope those help.

Interesting idea....though I don't own a compressor. I'm actually thinking of paying someone to finish this up and work out the bugs. I simply don't have the time to work on it and when I do find time I find myself rushing to get as much done as possible and I start making mistakes and missing things......like great big vacuum leaks.
