Im on 4lbs making 400whp on a built vq35de using a momentum gt37r kit. When I go into boost my radiators are cracking at the plastic points (oem). Not coolant oil mix, no overheating, no coolant out exhaust yet all my research points to headgaskets. Could it be anything else? Any test I can run before paying someone for a head gasket job?

 

do a test for exhaust gases in the coolent system.

 

^thinking blown turbo seal?

 

Why would exhaust gases be in the coolant? I believe my turbo is fine

 

Auto mechanics 101

Exhaust gases can escape into the coolant via the leak in gasket between the head and block into the coolant passages.
