Hi all, just joined this great forum, I have a problem with my p38. Itis a 4.01 Ltr model with gas conversion. Lately it has developed a ticking noise, it seems to be coming from the right cylinder bank and sounds like a noisy tappet. Starts on the button, no smoke, no misfires runs sweet just this really annoying ticking that seems to be getting louder. Any ideas please?

Welcome!
