Well,look's as if i join the cracked manifold club on the 5.4L engine.I got my old manifold off and got the new one today.I'm gonna put the new one on tomorrow.Just wanna say thank's to everybody for all of the valuable information regarding this problem.Thing i dont understand is what made Ford decide to use a plastic manifold intake in the first place!
Thank's
Danny
