I bought my truck (a 1993 F250 IDIT with a ZF5 Transmission) last year. The truck has been repainted and has obviously had the engine out at some point to paint the firewall. The Vin on the truck is M (which if not mistaken is a N/A truck) but has a factory turbo on the truck. When I bought the truck there was no history on the truck. This is all to say I have no idea what internals it has, if it has been rebuilt, or the mileage on the motor.
Recently the truck has been losing coolant. I haven't seen any coolant in the oil, haven't been making oil and haven't seen oil in the coolant. I haven't had any smoke. I have started to see coolant on the driver side back of the block around the head gasket. There is obvious coolant in the area and dried coolant immediately under the head gasket. I don't see any coolant leaking when sitting or when at idle so I'm guessing its leaking under pressure.
If i'm going to have to replace head gaskets, I would rather pull the motor and stud the heads. Here is where the questions come in. What all should I accomplish while the motor is out? Currently Im not in a rush to get it done because oil coolant don't seem to be mixing; however, over a 300 mile trip from Eastern NC to Va mountains I lost about a half gallon of coolant.
At a minimum I plan on having the machine shop go through the heads and I will stud them. If the cylinders look ok and the rings are good should I just leave the block alone? Should I pressure test the motor before pulling it to see if I should start planning on more repairs or just see what how it looks when I pull it? Ideally if everything looks good when pulled I would like to spend my money on the following
Headgaskets
Valley Pan
Studs
Downpipe
Exhaust
Oil Cooler seals
Turbo Seals
Camshaft
Wicked wheel
