Yesterday i finished replacing the drivers side head gasket due to what i thought was an internal head gasket leak.
Internal Head Gasket Leak
I have the same exact problem after HG replacement. Coolant burning out of exhaust, P1507 Code. Irregular idle, Struggles to run at low rpm, above 2 or 3k is strong.
I'm looking for input as to how to go about checking the turbo for internal coolant leaks.
