Looks like valve stem orings. You shouldn't here one cyl clatter above the rest. If you are using actual 6.2 long body injectors,they won't work very well. Especially combined with diamond precups ,which are very unforgiving to wrong timing and or coarse spray patterns .

I would back the timing down alot,and pop test all the injectors.

Don't forget to plug the little hole near the top of the cyl.

Could be a clogged lifter,or broken valve spring. A bent valve is not likely. If you got too carried away with valve lapping,lifter preload can be excesive.

You might need a stronger spring. It must be opening while driving.

Yes, it has a pinch bolt holding it to the throttle shaft. This will adjust idle and part throttle advance. There is also adjustment at the bottom of the arm,got to be careful with that one , it changes timing everywhere.

Does it still rattle at 10 psi boost ?

There is a timing retard cam on the pass side of the pump. Somebody may have adjusted it to far onto the retard ramp.

Leaking metering valve, or air in the fuel. Sometimes more internal timing advance helps .

Mostly small adjustments .

I run a modified injector pump,and a charge pressure gauge.

I got them on Ebay. I've been running Holley pumps,but they hate thick fuel. Have it set around 20 psi.

They are Bosch. I do miss having the pop psi @ 3850 . Now that its winter, they would work fine.

I used kerosene or diesel fuel a few times.

Your head and rotor are worn. Thin fuel will just leak through at cranking speed. I had to lower my pop psi from 3800 psi down to 2000 psi so it would start hot. To run high pop psi injectors you must have a very good head and rotor. Or run waste oil with a worn pump.

For more charge psi at full throttle and load.

I always use indian head shellac to glue them in place. After it dries scrap the excess off with a razor.

It would set a code . The fuel mixture should be fine.

Just get a factory blockoff plate at the junkyard .

Iv'e tried it,didn't work and fried the heat gun from leaving it on way to long. Was one of my motors with a very low compression ratio,and a cam with overlap. Put new glow plugs in and it started fine.
