I took the turbo completely off and ran straight manifold and got no coolant to come out. I pressurized the coolant lines on the turbo and cant hear it leaking....maybe the turbo needs to be warm to leak??

well crap.....brought the turbo to work and hooked it up to a smoke machine to see if it would leak....nada.....CRAP!!! I am going to go home again tonite and get a new radiator cap and see if i can get the engine to leak. This is freaking weird.....

Does that smoke machine pressurize the smoke? Maybe you can try hooking it up to a compressed air source (with the outlet plugged) and listen for any whistling sounds ......

SH*T!!!!! OOOOkay soooo i just came home and let the fan cycle TWICE and no coolant. I pressurized the turbo with 60psi of air. PLENTY of presure. HOW MUCH MOISTURE do you think is in an exhaust system???

Maybe its one of those ghost in the machine problems - i guess all you can do now is to make sure all the fittings are ok and watch it closely - unless you have a spare turbo lying around ......

It could just be that one of the seals leaked some coolant and then got seated properly (due to the pressure/temperature) after some time.....

Im thinking the engine needs to see the pressure of the turbo to leak? I am gonna put it allll back together again tonite WITH the turbo unhooked from the coolant and start from there.....
