The car was running great, cold night, was creeping up to 13 psi. I have 850 primaries so it wasnt a problem. The car was pretty hot so i let it idle in front of a fan after we were done driving. The next morning i am now only hitting 5 psi. I tried doing a pressure test but i think i am doing it wrong. I clamped a capped pipe with a valve stem into the TB elbow and filled it with air, it sounded like it was all coming out of the air filters, do i need to cap them also. all the couplers seem tight, cannot find any loose vacuum hoses.

 

how long did you let it warm up for?

 

when i did the pressure test? i drove from my house to the gas station to use their air, probably 2 or 3 miles.

 

my car is doing the same thing..... pretty much the exact same thing

other **** too.. =[

 

what else is it doing? If i find anything out ill let you know.

 

the low coolant light goes off randomly, and quite frequently. and my water temp spikes and drops (from 50% - 75% then back down) it doesnt gradually go up or down just jumps. and also as of the other day my idle spikes up and down to between 1.5 and 2.7k

 

5 psi throughout the power band? Your sig says you have a cracked apex seal? What's that all about? Are you driving it knowing one of your seals are damaged?

Do a champagne test, sounds like you have exhaust gasses in your coolant.

 

Do you have a real water temp gauge or are you just reading off the stock gauge (that is nearly useless)?

 

i havnt updated my sig yet, i rebuilt teh engine have around 1k miles on it so far. 5-4-5 boost pattern sometimes hit 6 or 7 psi if its cold
