Alright so I got her running and she ran for about 20 minutes total before she fouled out the plugs. Cylinders 1,2,5,6 all had oil on the plugs where cylinders 3,4 were both black soot covered. Not sure what that tells me. What are you guys thinking

Ok so if I had water filling 1256 would that mixed with unburt gas make an oil consistent mix? Could it just be that? Or do I have a ring issue? And what is causing the coloring of 2,3 plugs? I dont know how to upload photos

I would guess your rings are shot. Do that test where you wipe your finger in the tail pipe I described. It doesn't sound like water/coolant.

Do a compression test. Then repeat it putting a teaspoon of oil in each cylinder through the plug hole.

Even if it were leaking coolant, you'd be pulling the head anyway to do the cylinders. Depending on the condition, it might be cheaper to find a good motor to swap.

Fresh gas.

Blown head gasket
Air blown from radiator with cap off
Bad valve guide seals
Blow by from valve cover vent

Sound right?

I get no blow by from dipstick at all but will from the vent.

I also think my #1 injector is sticking since I pulled the intake and have about an ounce of gas sitting in intake port 1
