engine 617 ''dieseling"?
Was looking for any info about but no luck.....
Im new to this diesel engine (617.931 non turbo) i have it in my 300GD after i turn key off in ignition engine stops but after ...like 5 seconds .
Is this normal for those engines ? is that why they call dieseling in gas cars becouse older diesels dont stop right away? Just wanted to make sure if this is normal .Thanks for any input

You have a vacuum leak. The engine should shut down immediately.
I am in the same boat. As I noted in a previous thread I have a similar problem with my new 617.
The engine used to stop if I had the driver door locked.
Now I have noticed It will occasionally stop but, the standard is for the motor to continue to run until I press the manual shut off.
My related question is if the occasional shutoff by key is a sign that that shutoff valve may still be functional.
I mean, can it sometimes work and sometimes not? Or if it's dead it's dead.
not to jack your thread but...

Pump it with a handheld vacuum pump or suck on it.

If it has the m-pump (actuator on top), its about as easy as easy can get.

once you get it out you could see if it will work under vacuum. That bit costs like $150. Maybe you could seal it up with new gaskets and save $ ???
here is how to replace it.

Force, my vacuum hose goes to plastic housing directly on top of inj pump .Is this M pump you were saying is very easy to change valve?
Im not sure if have M pump .my vacuum hose goes vertically to plastic housing not on side like M pump has.
Another question what coolant type is recomended for 617 engines and what %(50/50?)
appreciate feedback
