Hi I have a 1992 f.150 with the 302. We recently installed a brand new engine block that has a knock in the top end. I suspected rocker arms or lifters. Removed intake manifold and valve pan and rockers seemed tight. If i proceed and take off the intake, what exactly do I look for when looking for a noisy lifter? If I have to re-install the rocker or rockers during the job on the 1992 stock 302 do i have adjust or just torque them down tight? Appeciate any help thanks.

 

If it's new, it has warranty.
I'd be turning around and demanding a new one. Had the same issue but the wrist pin in cylinders 6 & 8 walked on me

 

Yeah thats the down side of it. My brother installed it two or three years ago and ended up buying another truck after the job. Suspected a wrist pin knock but never had time to bother with it. The truck was than layed up. I just got it out again and exhausts done over on it so i can actually hear the engine and it definatley had a knock. Pulled plug wires one by one but no change.

 

i think warranty was 12 or 18 months
