There isn’t much difference really, the head
is more important on a Diesel
, the valves need a better seal at those high compressions, but your better off having a machine shop do any head
anyway unless you can grind valves / seats anyway. I like new bronze
and injectors it’s my opinion those go to a professional shop too.
If you have wet liners, then no boring or even honing, just check ring gap. If you overhaul
before its real bad then most likely the crank can just be polished and go back with standard bearings, most of the time the cam will be fine too as valve spring pressures are low as RPM
Don’t spray bomb paint
though, use a high quality ideally two part paint
, I like white Marine
Replace the oil pump
with new, I don’t even measure the wear, pump is just too important and usually not a great expense.
Timing the injection pump can be difficult or dead easy depending on the motor
, sometimes it’s possible to time 180 out so be sure it’s TDC compression
and not exhaust
Diesels are really, really easy, especially small inline ones, they are simple things really.
