HOw is that even possible to do that cheap?

Lots of non-defenders with the 3.9's out there getting parted out, and older disco's and RRC's are getting pretty cheap.

Low miles Block from a RRC $50
Used 3.9 heads $150
Main and Rod Bearings $60
Gasket and Bolt set from Will $170
Rear Main seal $10

Head rebuild $225
Assemble Engine $200

It can be done. Labor to swap this in for the old will be about $750.

Barry, you don't need to rebuild the motor, just a new gasket.

There are a number of less expensive things you can do while you're at it. I would replace your hoses and score some new stainless hose clamps if yours were old and corroded like mine.

If you haven't already swapped the plastic radiator cap for a brass one (as well as the identical cap that's on the bleeder line), I would do that, too.

Good luck Barry, dont get down about it. Think of it as "improving" your truck mechanically. At least it didnt happen far from home.

So my friend just checked out my truck. We added the coolant back in that the shop drained and we let it run for a bit. It crept up but was very slow. Drove it and it went back to the middle. It never went into the red. Turns out the coolant going in is cooler than going out which would make me think the radiator is clogged. Looking at the front of the radiator it looks like crap. Lots of fins destroyed. I had it cleaned and repaired four years ago but I think I need a new one. Going to call Will and start with that.

Odd that this problem came back a year later. Bringing it back to the shop tomorrow. They were going to do a pressure test over night to see if it loses pressure. So far the coolant didn't have any oil and hydrocarbon test showed no issues.

I would think that if my head gasket was leaking the radiator wouldn't have helped and an issue would have presented itself in the last year.
