So i just redid my head gaskets and put everything back together, all is good, minus a small coolant leak going into the turbo, and now whenever i get over 20psi boost and let off the gas it sounds almost like it is sucking air. Any ideas? Im at a loss and really cant figure it out. I've checked all the boots and everything looks good and tight, all the exhaust is good no leaks. Someone throw something out there.........
