gerry,
New York
So its been a while since ive done a boost leak test, so I thought id give it a shot tonight and here is what I found. tested to 28 psi.
LEAKS FROM:
TB seals (very loud leak)
BISS screw
meth injection nozzle (where its threaded in intake)
very small leak from a coupler (bubbled with soapy water)
and a pretty good leak from compressor cover housing.
would all these together add up to a large leak that would affect my MAF calibration in DSMlink. Should I redo my base tunes to get maf calibrated again after fixing leaks?
I rebuilt the TB with new seals and BISS "O" riing, tightend my clamps on IC piping and put an o ring on my injection nozzle. put some silicone around compressor cover and reinstalled. Tested again to 30 psi and it bled down about 1 psi per 30 secs, then when it hit 15 psi it stayed for a long time, so should be leak free now.
