Anyone had this problem before? It's starting to drive me crazy . Just redid my gaskets bc they weren't done correct when I purchased the truck . Bought a set of used heads bc mine were cracked to hell. Got them checked out and they were good Togo. Put everything back tg and anything past half throttle looks to me as if it's coming out of the return not the cap of the degas bottle. I did install a new mishimoto coolant filter when I redid the motor I'd if their hoses have had problems or not I have 2 screw clamps on the hose still nogo. Delta's are perfect any help would be appreciated
