Massey Ferguson 135
I have a 135 Massey Ferguson diesel that acted like it ran out of fuel and quit and won’t start back off starter but will if you pull start it but then it blow oil out of dip stick tube. So we took crank case breather tube off valve pan and it was not stopped up so we tore it on down and the head and piston also the sleeves all look good what else could it be it runs great and sounds good when you pull start it just blows to much oil out of dip stick tube to run it

Sounds like you've got some serious blowby, did you check the head gasket..?? Could be blown between cylinder and oil return ports.

Did you pull the dipstick to see how much oil is in it..?? Injector pump may have put a lot of diesel fuel in the crankcase, and running pushes it out. That much the oil should smell like diesel.
