This does not explain why the pecking subsided when you pushed down on the rocker nut though.

Thanks Boog, that gives me some hope that it’s the fuel pump. But I agree, it is strange the the noise left when messing with the rocker arm nut... That’s one reason I’m leaning towards something to do with exhaust, cuz it was the #2 exhaust valve I thought was tapping. But it also doesn’t seem like an exhaust leak because it doesn’t fade when warmed up like I’ve seen before....and it sounds mechanical. We’re heading out camping this morning so I’ll only be able to ponder it for another 5 days.
