I always have some leakage and coolant outside the cap and on tank after nunning hard for 100+ miles ( my weekend commute home from work & back ea. way is 150+ miles )...Its not puking it all over the place or dropping coolant level to any questionable level as I'm keeping a close eye on that ..
do these caps go bad seal wise ?? i noticed there is some type of spring in there and looks to be a checkvalve ?? of some sort could this be getting weak or worn ??
