Boost leak test concerns...
Yes, another boost leak test thread!
I just got back from getting a boost leak test done. Pretty concerned with the outcome.
We took off the mas/filter and secured the tester. Started up the compressor and began the test. We heard a small leak with the throttle body seals. Very common thing with evos.
One strange thing is, my boost gauge would hold no more than 8psi MAXIUM. We were using a 200 gallon air compressor FYI.
The thing that most concerns me, is you could hear the compressed air flowing out the exhaust. If you'd put your hand down by the muffler tip, you could slightly feel the air coming out.
So, the questions begin:
Anyone experienced this? We're assuming it's possibly bent valves?
We're doing a compression test tomorrow to see what we come up with, but any suggestions/comments are welcome!
Thanks!

Lots of us are having boost leak issues.hehe ( a few threads on here just form today).
I have one as well. When your testing at 8 psi, did you hear a noise, like something manually opening up when it started to leak? Reason I ask is I am in a similar situation as you, but I have that weird noise.
