found some leaks

[jdmser]

I'm in the process of hunting down my poor idle/ ignition signal code and found a few small boost leaks. Click here to watch boost-leaks Anyone know what vaccum during idle should be at with tomie cams in a rb20?

my vac on a good day is -7psi, no idea what that is in mmHg tho.

that's about 14.25 inHg and I've only been pulling around 10

wow so every weld on your piping is leaking? who welded it? its hard to tell in the video but how did you hook up the piping to an air source to check for leaks?

-7psi = -362 mmHg

I did. It didn't surprise me that they leaked. It was my first attempt at welding with oxygen/acetylene. It's more brazing then welding. To pressure test it all I did was get two 2" pvc plugs and an air nipple. Put one plug in one end and clamped it down and tapped the other for the nipple and clamped it down. I had the compressor set at 20 psi, that's as low as it gets. Last night I started to grid off the welds. When it's all cleaned up I'll be taking to a guys that works for me and he'll be doing it right, mig or tig ftw. BTW I did check it before I painted and put it on. I guess it couldn't hold up to the extra heat and vibration.
