Friggin rocker arms clacking
Ever since I put my engine in I have had this clacking problem. Hes a long story short.
Engine- from a friends car, ran flawlessly, I put it in my car now. Specs- supposed to have an F303 I think otherwise. Comp cam hardened pushrods (elcheapos) stock length and stock rocker arms supposed 600lift springs also. E7 heads , stock style lifters. No shims under rockers cept the factory "U" shape shim. Problem no matter what I do the rockers on bank 2 seem to rattle and tap. Yesterday I pulled one rocker arm and where the fulcrum sets in the rocker looked a little scared so I replaced with a spare to see what happened. Results that one tapped louder. Today I pull the comp pushrods out and replace with stockers and put everything together and torque rocker bolts to 28ftlbs. Result still ticking and tapping like it always did. I do not suspect lifters bleed down cause they are hard to push in with rocker arm or pushrod manually by hand. So now I am grabbing at straws here. Should I remove the stock style rocker shim? I have never heard of someone doing that. |
