They seem to be evenly worn. No other lifters are chewed up like the #4 exhaust was.

I’m actually happy to hear that. I have no basis for comparison but I was just expecting the lobe in question to be noticeably (to me) worn down. However maybe this was enough to not actuate the exhaust valve and cause the miss on #4. I’m just hopeful that by getting everything cleaned up and new parts put back together that it will run.
The good news is it had to come out, so it isn't work in vain. Occam would say there is a pretty high probability the lifter (and damage it did to the cam lobe) was causing your miss.

True. It’s more than coincidence that the miss was on the same cylinder that had the lifter damage.
Let's hope so, although fixing a miss should be pretty straight forward if you know the mechanicals are all straighten out.
Did you decide to have your injectors tested and cleaned?

I called around to a few local shops and no one did injector testing. I bought a rebuild kit with new injector screens and o rings.

I didn't know they could be taken apart. Do you have a link to that site?

Did you get anything else for the disassembly and cleaning? Saw these products underneath.
Tony did you get flooding from Henri? I’m watching the news and they said Jersey got hit.

Not in my neighborhood luckily.
A few miles away got flooded really bad. People were being rescued by boat.
Lucky, that’s great.

I know. We got caught in Sandy. My gf and mother had to get rescued by boat. Boat came right up to the front door. I hope we never go through anything like that ever again.
Is that why some of the houses around there look like they have a serious lift kit?

No. Sounded like I just needed a screw to remove the old screens

Ahhh, you noticed. Yup, that's exactly the reason. Where I live now, basically down the street over a house is an inlet that feeds into the ocean, so water is pretty close to me. I wasn't living here during Sandy, I lived in Lake Como, which was 3 blocks from the ocean. Flooding was so bad only the very top of Stop signs were showing. Everything was under water.
