94 ranger with reman motor burning oil

[Ewgoetz]

So I’ve been suspecting my motors been burning oil but no signs of smoke.
I did have to add at least 1 quart of oil.
It looks like it’s leaking into cylinder 1, first cylinder on the passengers side front.
Any ideas on what might be causing it?
Head gasket?
Lower intake gasket?
Looking for ideas what to check or how to check things.
I’m thinking it’s unlikely the pcv valve, cause all the other spark plugs are looking ok.

Could be a valve guide seal has popped off on intake valve for #1

Have to pull the valve cover to see if that happened.
You can replace valve guide seals with heads in place

Not a head gasket issue or lower intake gasket

Piston rings can leak oil, need to do a dry and the wet compression test on #1, #2, #3 to determine that.
Need a reference from #2 and #3 to check against #1's numbers
