poncho62 thanks for the tips, will checkinto them. As for did i use moly grease, yes i have done a few cam and lifters for others so i'm familar with the procedure on how to do it, the only reason i replaced my cam and lifters was the fact that i had the top off the engine to replace the heads and had a look at the original lifters and found them to be concaved so thught i might as well replace them and the cam while i had the opertunity. It's just odd that i would have 2 new lifters that would pump up and then go flat on me never had that happen before and was just wondering why.

UPDATE
i have taken the intake off and this is what i found, the one lifter in question not only isn't pumping up but was stuck down in the case, almost as if the spring couldn't psh it back up. I disassembled it and found nothing stuck in it but when i put it back together you now can fell the spring pushing back, so i can now pump it back up, what would make it stick down in the case?
