Might as well change the vent filter. I think I will go with the big one. Will see if I can replacement fuel lines.

I think the tank is in finally. Just need to figure out how to connect the fuel level sensor to the “new” harness

I found it was pretty easy to disconnect the sender on top, attach different wiring.

 

[coldtaco]

I replaced the cab back main wiring harness with a “new “ takeoff harness. Had to incorporate the old wiring into the new harness. I think I got it all to work, tail lights, rear tank sender, and trailer lights.

Pulled the head off today can’t see anything obvious to cause signs of a head gasket leak. Pre-cups show signs of cracks, and the gasket part over the Pre-cups are cracked.

Any idea of the milage since new, or sinse last overhaul. Just trying to baseline my Hz with 260KM's on the clock??

Also, is that a fibre or metal head gasket??

Guessing 15-20k miles since overhaul. Factory/fiber type gasket

 

[coldtaco]

Is it normal for head bolts to get rusty and/or pitted?

 

[coldtaco]

Dropped head off at machine shop to see if all is good.

 

[Reinhardtius]

Good luck, she looks ready otherwise

 

[coldtaco]

Head has a crack so now it’s just a lawn ornament

 

[cruiserdan]

Bummer.

 

[tmarx]

Eish ! Sorry to hear

 

[coldtaco]

The bigger of 3 cracks, went through the valve seat

Wasn’t this engine recently rebuilt? That’s bummer news indeed.

I’d be making a cost benefit analysis on an engine swap if I was in your boots.
