I started the car after sitting for 3-4 weeks. It ran fine for a few minutes but then this started. The noise does go away for a few seconds intermittently but comes back. I think it's a stuck valve hitting a piston.
Maybe a lifter loosing its oil? May be a dumb question, but how is the oil level in the engine?
Coming from the wrong part of the engine for that though, least according to the OP....??Go buy a new fuel pump push rod.. You have an apparent clicking from the worn rod. I have changed 2 rods out in as many months. The Comp Cams rods are ****. If you can find a NOS one you are miles ahead. The after marked rods are all junk.
Here is a post that shows just how much these new push rods wear out. And it does it fairly quick.

When the GTX my friend owns started tapping it sounded like a lifter. I thought it was until I pulled the fuel pump to look at it. ANd it was worn down. Not saying this is his issue but it is worth looking at.Coming from the wrong part of the engine for that though, least according to the OP....??
Go down the row and see if you can push any of the pushrods down by handi took off the driver side valve cover and everything looks fine. Rockers all stable, nothing weird with pushrods. Maybe I should start the engine with the covers off and see what happens...?
Interesting thing about the fuel pump, I see about 4-5psi of pressure. It used to be around 7. But the noise definitely seems to be from the top driver's side of the engine.
It does look like the flexplate is hitting something.Not a lifter....too fast at idle. Sounds like all the flex plate bolts hitting. Check the inspection cover.
