Right if it is the 4.0. if it is the 5.0 those are really good and worth the repairs. I had my Mountaineer, that is just a fancy Explorer, over 200K and it had the 5.0

The only reason oil is getting on plugs is when the vehicle overheated that made the oil loose its viscosity and made it thin like water once you change oil and get the right viscosity back the oil will stop leaking.

I have to disagree whit Firebird on this... If oil is thin for some reason a properly sealing gasket will contain it. Also getting the oil very hot will not likely reduce it's viscosity all that much. More than likely the engine got so hot it cooked the gasket and ruined it. The heat required to ruin the gasket may have caused engine damage. Which engine do you have? How many miles on the vehicle?

157000 & 4.0. Vehicle starts drives but misses at idle. I figured because visible oil coming from head dropping on # 5&6 plugs. Considering using new bolts to re-torque head to see if that fixes if not then thinking about replacing head. Anybody got misgivings about plan of attack?

157K on a 4.0, you are lucky you got that on the 4.0, most of those in my area have usually went between 90 and 110K. Re- torquing the heads even with new bolt rarely ever works, it usually makes it worse cause the torque is reduced then reapplied causing more separations in the gaskets. You may not need to have the head replaced, have it checked by a machine shop once it is off, it might just need to be milled to make it flat again. When the head is off make sure you inspect the cylinders look for any scouring or cracking and the tops of the pistons for burning, if you find any of that then you need to make a decision on if it should be pulled and overhauled or replace the entire engine.

If it is a 4.0.... I am pretty sure the engine needs to come out due to the additional cam timing chain located at the rear of the engine. I would get a service manual if you are going to attempt this yourself.
