Ok thanks for all the help and ideas. The rear plugs were leaking even after the jb weld. We used a longer plug with red loctite and it seemed to stop the big puddles. Now this 69 428 has a PCV on one side and a regular cheapy breather fill cap twist on type on the other valve cover. When I really get on it the dipstick blows out a few inches and it shoots off like old faithful. I assume the dipstick is just not the right one and it doesn't fit well so I have a nice one coming. Does anybody think we need to put anything elsd other than the cheap breatrher cap on the other side or remove the PCV and let it breath better? Problem is nobody makes that nice K & N filter in a twist in style.
