Hi guys i hope you can help me with my problem.
I have a 25/30 setup running a 35/40 turbo 20psi.
i had a cometic head gasket go on me about 5000km ago so i removed the haed and had it checked with no faults found.
I replaced this gasket with a nitto one and have had no problems till last weekend. I was up it for the rent and things were all going good till i got of the power and then about 1 min later i went to get back on it and the car made no boost. first thing i thought was that i had blown a cooler pipe but this was not the case so drove the car home which was about a 90 min drive in last sundays heat (car did not get hot).
when i got home checked turbo intercooler but no problems. i then removed radiator cap to find it had very slight milky warter. i then tested the head gasket with a die tester and it was inconclusive.
so im about to remove the head and check gasket by my biggest problem is where did all my boost go i have had a gasket blow befor and the car still made boost but now i cant even make 2 psi.could there be something more serious i a missing. i have no blow by and car still runs fine of boost. any help on what to look for would be great. i will be testing the head again for warping cracks and all so crack testing the top of the block. just so you know it is all forged,drysump,head drains,vct,all bolts are arp,car is/was making 450kw on pump
Any help would be great
Thanks Neal
