Laser Problems

[john]

I have the car running but it does not want to idle. I recirculated the bov, installed a stock MAS and the car does not want to idle. I tried a boost leak test but it does not seem that the air is going in. It seems to be going out as quickly as it goes in. I replaced all the vaccum lines and the problem still exists. The ic piping was made and everything is tight. I was told that it could be something with the turbo. I pumped air into the wastegate actuator and the actuator opened. So, it is not stuck open. The other theory is that it could have a couple large cracks in the exhaust housing. Could the cracks leak enough to make the car not idle or hold any boost? I still have to hookup the logger and adjust the throtle cable correctly. The car starts but you have to keep it running with the gas pedal. Whild feathering the gas, the car kind of stumbles like it has boost leaks. Compression is good (160 across) except for cylinder 2 which only gets 70psi. I am pretty sure it is something in the head though. Shouldn't affect the problems I have now. Any ideas as to what the problem is?
