I picked up a full PBM package for my engine that I've built and so far everything is working great except for the heater core bypass valve exploding on me half way trough my cam break in.... nice souvenir on my arm from that but back to the topic, both my valve covers are leaking and it apears that the overhang lip of the cover is not clearing the aluminium heads. has anybody encountered this issue? they are perimeter mount covers and they came with the top end kit that I bought, you'd think they would fit :s with the ac still in the vehicle is there a trick to removing the cover on the passenger side short of pulling the engine out? and to make it that much more fun I have a supper ram on the engine and edelbrock shorty headers with the air tubes ..... I dont want to pull an engine for a simple valve cover modification!!!!
