Tapping Noise
Hello from England
I am hoping you guy's may have an idea what is wrong with my Jensen Interceptors engine, it is has a big block 440 engine. The problem is when I start the engine from cold I get a loud tapping noise which gets quieter when the engine is warmed up but never really goes away. Most people have suggested it is exhaust manifold leak or hydraulic lifters, I have replaced the manifold gaskets and all 16 hydraulic lifters but no change. I have now ordered from Mad Dog in the USA a set of adjustable rockers which I hope will be here soon but as you guy's know these engines better than anyone else I thought it was worth asking you. The engine was rebuilt a few years ago and has only done 12000 miles since then, the oil pressure is good and there are no other symptoms. Any help please Michael |
did you check for cracks in the manifolds? or at the collector of the manifold? i have a hard time thinking the rocker shaft being that worn, i think i would try lash caps b4 buying new rockers, thats just me tho,

Hi Bob
Thank you for the advise but what are lash caps :D I'm from England so we I guess have another name for it. |
lash caps go over the valve stem to make up any unwanted play at the rocker. they go ontop of the valvestem under where the rocker contacts
