I've heard it faintly when cold for a month or so now, but driving back from Willow Springs road course I could hear it when warm and it's louder now. The engine is running fine, but it has a noise that I have narrowed down to the area under the valve cover of cylinder #7 using a stethescope type device. I believe it is in the valve train. It is not an excessive valve lash sound...it has a different sound. The valve lash sounds normal...there is just another sound coming from the head on that cylinder. The cam is a 282S Comp solid lifter flat tappet. The engine has about 4000 miles on it now.

Like I said, the engine is running fine so I don't think it's a wiped lobe. I'm thinking worn valve guide or bad pro magnum rocker or a busted spring damper (unlikely) or ?? When I started it back up again after being home for a while it was not very loud even after warming back up so it seems to be inconsistent.

I'll get around to taking the valve cover off this weekend.

Any other guesstimates of what it could be?

Pull the cover off, if its a rocker, you'll see it, maybe lucky.

If not, guides dont usually make noise

Backed off rocker nut/poly lock?

Pull the cover, its easy to do and will let you rule it out.
