Hey guys im having trouble diagnosing this. I have head noise on the intake side on my p72 head b18c engine. sounds to me like maybe a rocker arm or something seems too loud to be lost motion assemblies. it drove fine on the way home from work and the the next morning when i start it i hear this god awful noise. Not sure what it could be. The engine is in time and the valves seem okay. Any help?. please?

Thanks, Logan
