Was listening to Merle Haggard------------

And I was putting a rebuilt injector pump back on a 4020 Power shift. Every thing was going good. Put in new batteries and cleaned the cables up good. This tractor has been setting for about 9 years. Had the gear shift in PARK. But I could not find anything to wedge in the clutch pedal. So I made a jumper to put in the harness so I could crank it over. Don't call Barney just yet! It cranked over real nice with the new batteries. So I was watching were I had the fuel lines still loose at the injectors as I cranked it over some more. All six had fuel. So I stopped cranking and tightened the lines up. It started right up and ran real smooth for a few seconds. I was between the brake pedals and the right rear tire and all of the sudden I heard a big bang! Oil, antifreeze and fuel went every where. But the engine just kept running and blowing out more fluids. I pulled the throttle knob out and put the lever in the off posistion. But it kept on running at a low idle. I put my finger on the lever on the injector pump and got it to stop. Now I can see parts of the head gasket sticking out of both sides of number six and sticking out of the right side of 5 and 4 as well. I still had the radiator cap off and it blew some out there as well. It does not have a turbo. What could have happened?
 
Listen to Rainbow Stew and tell me that Merle didnt have a hero of eery foreshadowing 40 years ago!
 
I don't know...

It must have been looking for a place to fall apart!

But some day we'll look back and say it was fun. Just not today!

Meanwhile, I think I'd just stay there and drink!
 
A lot can be forgotten in 9 years.

-Did someone have the head off and not torque it up afterwards?

-Bent exhaust pushrod or something else in the valvetrain preventing an exhaust valve from opening?

-Could it have been overheated and hurting before it was parked 9 years ago?
 
Did that 30 years ago. Stood on the ground next to the side of the engine and started it the day after a 2 inch rain. It started and blew the head gasket out from under the head and gave me a bath. Tom

Injectors leaked antifreeze into the combustion chamber would be my guess.
