Coolant leaking past lifter, onto camshaft and into crankcase-yeah, that' what I said

Jeeper
84 CJ7 AMC 258 i6 / 4.2l motor- I dropped my oil pan to replace the rear main seal since it had been leaking pretty bad. Was not having any issues with coolant in the oil or running hot,etc., just need to replace the rear seal.
The next morning I walk out to the garage to reinstall the pan and there are drops of coolant under the block
I was trying to figure out where it was coming from(it's not coming from outside, it's leaking internally, so I pressurized the radiator to about 30psi. The coolant is dripping from above the cam, intake lobe. It looks like somehow it is leaking past the lifter!!!
When I bought it a month ago, PO said he had replaced the head gasket(it was obvious up above that it was done, new gaskets) because he had found coolant in the crankcase-supposedly he had the head milled before reinstalling. The Jeep was running fine but I noticed in the last few days that a lifter was making noise after it had sat for awhile(maybe it was the coolant) I don't know if the head gasket blew out again or what-not sure how good of a job the PO did-he seemed pretty inexperienced.
I've talked to a couple engine shops and a Jeep shop that's been here in Tucson for 40 years and they were stumped. Basically just said pull the head and go from there.
I was just wondering if anyone had ever had this problem? I'm hoping the block isn't cracked. If it's the head at least I can fix that, the block becomes a boat anchor if it's cracked.
Coolant is the red Toyota type-I have gallons of the stuff. So you'll see oil on the lobe to the right and red coolant on the left lobe-
Thanks for any ideas or suggestions you might have??
