66 Chevy C10 with LS motor & Afco radiator. Installed Afco 80094 cap on Afco radiator. Cap leaks from underside of cap. Replaced 3 times, same Afco cap 80094. All 3 leaked same. Installed cheap Murray cay, same psi 16, it does not leak. Do you think Afco caps all bad ?
Would like nice looking cap on show truck. Any suggestions to try ?

Any pictures of the engine bay, thinking of going LS3 in my 83 C10. ;)

It might be worth calling AFCO. Maybe they had a bad run on caps/seals and will solve the problem for you. Or, as others said, just use a different brand.
