v8 engine noise
My 52 flat 8 is some times making a noise,does not sound like a rod,more of a coaking noise,on ocassion,seems to be in the top.I do not hear it at idle,and goes away when revved up.It does not have a deep sound like rods i have heard before.I am not at the point to want to do any serious engine work right now,but do not want to damage either.Experts chime in please.

What about what Josh found in his intake. It's on page 2 of my current thread about an 8ba. I have a very similar sound in my small cummins that's in my '59. Mine makes a lightweight, odd sound for a short duration in mid revs. Not there at idle, not there at speed, just like yours. Josh's picture got me thinking about my diesel, maybe he'll chime in and tell us what that bolt sounded like. It's an amazing photo for sure.

Its a thicket find,has not run in 20 years until about 2 years ago.Exhaust were rusted off at the manifold until i built a crossover this summer.I do not think it is serious,does not have a pattern to it.I have a lot of mechanical experience,just not with flathead v8s.Keep the sugestions coming though,you always can learn.!!
