Lifter tick (I think)?

I would try some seafood or something... Probably just a hydraulic lifter on its way out.
If you're gonna change the heads I would just put a new cam and lifters in it when that time came...
That's the plan but I was hoping for next year, so for the time being would be nice to quiet then down. Will get valve covers off later too and see if everything is stil tight under there.
Whats the oil pressure after you Get On it?
Predetanation or dieseling?
Oil pressure is exact as picture says regardless of how it's driven.

Don't think predet, initial is at 13 total 33 ish @2800?

I originally had timing at 18 as it seemed happy there but it pinked a bit, but now I'm wondering if the noise I heard was actually the lifter ticking instead.

Drove it around today after topping off the oil (was a tad low) seemed a little healthier.
