Boost Leak, Where?

92gsTEX · 11-28-2003

As some know i just got a 92 mitsu gsx w/6bolt. I had john, james and james over all lookin and trying to find where the leak was comin from. We KNOW thats its comin from behind the block thinkin its the intake manifold gasket?? the boost cant get anywhere on the aftermarket gauge not even past 1psi. Could there be any leakin hoses behind the block?? where r they?? any help is much help.

its probably something a whole lot bigger than a gasket. try the intercooler pipes

No its not a intercooler pipe. You can here it coming from the intake man. You stick your hand behind it or next to it and you can feel air. Is there any vacum hoses back there or anything to that extent? Its quite a leakin the gasket if it is though. We took his comprssor set it to 25 PSI and tried to feel it after getting frustraded. Only got 1 PSI! The car stil builds boost when driving though. No shaft play on the turbo and it spins fine.
