Maybe I missed a previous thread, what issue were you experiencing? Blown head gasket? I replaced some energy cells on a friend’s D19 turbo diesel a few years ago. Any of those leaking?

Previous owner let rain water get in exhaust.

Was just gonna replace 2 damaged pistons and sleeves but found 6 new pistons and sleeves....
It otta run like new now....

Injectors all pattern well...

Tractor had been well maintained as engine had been overhauled in the past...
As well as newer starter, generator and brand new tire....
It did have a steering issues and i belive that's why they parked it...
