Ahhh, I had forgotten about the plastic coolant elbows I will order aluminum ones right now. And all the radiator hoses have been replaced (somewhat) recently and appear to be in good shape but thanks If it does turn out that i have a leaky injector I will go ahead and order all new, any suggestions? ZZP has a unreal amount of options and I'm unsure if going an bigger would really give me any benefit without upgrading fuel pump as well? And I will do that test tomorrow thanks for the suggestion
