lI will update the thread with what I find, but I agree with Hotrod Lincoln and 52Carl that a full overhaul is needed. The magnetic drain plug had a bunch of stuff stuck to it, and the small amount of sludge in the bottom of the pan looks like metallic paint. There are some fairly large bearing chunks as well.
I dont know why the difference in compression exists, but I agree it should be addressed, and at a minimum I will hone it and put new rings in it. I will have the head checked out as well.
The sad part is that this was rebuilt only 3 years ago and has less that 10k miles on it. Oil got changed religiously with Brad Penn 20-50.
I haul things quite often, I was delivering some large trees when my engine failure happened, but not super heavy things.
