Changed all the hoses. I didn't take the valves out of the heads, they were pretty much mint looking. I didn't want to get into relapping them and valve seals. it only has 2800 hours on it. I wasn't going to even pull the head but the gasket kits came with head gaskets so I figured what the heck. I set the valve lash. There was almost zero wear on the sleeves.

I'm Rebuilding the turbos also.
I caused this mess myself by running too much oil in it.
The specs call for 2.6 gallons I have been running 3 gallons even. Because that's where it reads full on the dipstick.

The dipstick is marked wrong on these.
There is a short stubby dipstick on one side and a flat one on the other side. I have going by the flat one. Big mistake. Too much oil blew out the rear main. That plus the running angle of the motor.
You can see these two stick give totally different readings
