Cummins keeps turning after I shut it off
 

Today and yesterday I noticed that when I shut off my truck the motor continues to turn. It's not getting any diesel or still "running" it's been doing some heavy hauling lately . And just recently had its head rebuilt with a new head gasket. Any ideas? It doesn't seem to have less power or smoking more then usual

Can you be more specific on the symtoms. THis is rather vague & Im not sure where to go with this. More info.....:humm:

That's al I know. I shut the truck off and the motor cuntinues to turn but is not firing. Pervious to this it would shut off and stop turning immediately

All I can think of, right now, is a possible leaking injector or motor oil somehow leaking into a cylinder or a few. Just tossing it out there.:humm:

It stopped doing if for a bit but it came back , could it be from cold weather or timing ? Is only seems to do it when it's cold like -30 Celsius . It also seems to start strange when it's doing this . It turns over more before it fires up

Mine did exactly that a few months back, starter was stickin and wouldn't shutoff. Couldn't disconnect the batt cable quickly so I smacked the starter with a hammer and it quit. About a week of that nonsense it was a little colder and it just went out.

All I could figure is the starter gear hung up on the flywheel and the constant turning with the engine runnin screwed it up? But that sounds like it could b ur problem
