I have a 4500 Ford Industrial with 3 cyl. diesel. I can run it for any amount of time, and when it sits for a while, I check the oil and it's over full. I even leave the shut off cable pulled out, thinking that might work. Can the injectors leak into the cylinders and into the crankcase over time when the engine is not running? Should I put in new injectors? Thanks.

If it has a supply pump on it, start there.
If not, then it’s the front seal in the injection pump ..
It’s really not a diy project but it can be done if u have the proper tools..
I’m assuming it’s a CAV injection pump.?

Faulty injectors usually fill the cylinder(s) while its running. Filling the crankcase while its not running sounds like bad seals in the injector pump that let the oil into the crankcase via the pump drive-gear housing.
Thannks for the reply. I'll check the pump and look into how much one costs. I know, NOT CHEAP.

Thank for the reply. I'm not much on diesel engine terminology, as far as CAV pump is concerned. It has a pump but don't know what type.
