Literally sick over this. I've done the trouble shooting and have info and pics.

Those numbers don't have me suspecting a head gasket. Is it ~using~ coolant?

If ALL the oil looked milky like that, I would be concerned.

If it's just gooey under the valve cover, my first question is "do you take lots of short trips that don't get the engine up to temperature for at least 15 minutes?"

Short trips don't burn off the condensation that collects inside the motor when it cools. Not good for the oil, not good for your motor. Creates sludge.

No short trips i am 15 miles from work. Something has happened it has never had the oil cap and valve cover with this mess.

Coolant level drop even sitting not running if I check it the next day. Yes loosing coolant. No external leaks and no leaks on heater core.

The oil will all look like chocolate milk if its leaking into the oil.

Drain your oil. If it looks like the stuff on your fingers, probably not good.

As a test, change your oil and filter, using some low cost oil. Make a note of the oil level. Let it sit a couple of nights. If you loose coolant and your oil level goes up, you have your answer. Drive it normally a few days and drain the fresh oil. If there is coolant in the oil, should be fairly obvious.

BTW - if those plug electrodes are as rounded as they appear in the pics, might be time for a change, once you get the leak question resolved.

Compression is good. No signs of a head gaskets issue.

When my truck had a bad head gasket it:

Was loosing coolant
White smoke poured out exhaust if truck sat for a while and then drove it
One cylinder was 100 psi more than all others.

Borrow, rent, or buy a cooling system pressure tester, pump it up to about 15 psi and see if the gauge holds. If it does not, you have problems.

That would be a real quick way to check. I know O'Reilly's rents them (former work experience), for whatever that's worth. The deposit is high (like, actually buying the tool), but it all gets refunded.

If it holds, breath a sigh of relief and move on from there.
