No rollover here, just curious. I always see pull the injectors or the glow plugs. On my tractor it’s indirect injection so I don’t see that helping. Do the glow plugs screw directly into the head normally?

I suspect what is normal is determined by the individual engine design. As I recall they did screw into the head on my old Mitsubishi tractor. They were above the intake manifold. I can't speak for other tractors.

On direct injected engine the injector screws into the head similar to spark plugs on a gasoline engine.

indirect injection. I suspect some port available for performing compression test but am not familiar with where it is located though.

I believe with indirect injection,the injector and glow plug thread into a pre-combustion chamber,which is open to the combustion chamber.
So,in advent of a rollover,either could be removed to allow turning over the engine and avoiding hydro lock.
Or wait until tomorrow and carefully bar the engine over to be sure nothing will hit.
Cheers!

In all honesty it’s just something the crosses my mind every time I read about a roll over. I did not roll mine and I’m not asking for a friend.
