Hey guys just had a rebuild done and thought ad run this by you before phonin company on monday. HAd new head with solid lifters etc but thought the tappet noise was due to this. Took my mate out and he said something wrong there he took rocker cover off to discover one of the rockers was vey loose so he sorted it out took it a spin tappet noise was away came back ended up it had come loose again. The bolt in top seems to go back in and not stay at desired clearance level like the others. is there and easier fix or will I have to wait and phone up on monday, not the kinda person to hassle so rather sort it out than have to tral to and forth. any help will be appreciated!!
