My car keeps blowing the seals out of radiator caps! Yes, i have an overflow tank! It seems to only do it on the bottle though! Could it be that the nitrous is finding a "weak spot" and seaping past the headgaskets into a waterjacket causing the preasure to sky rocket? Im not burning any or losing any coolant at all. Im kinda stumped on what to do? Maybe a higher PSI cap? The car will officially be down for the winter as of sunday (have one last race to attend this saturday)
