Valve Cover - The "black" one?

[Un-Hemi]

FWIW, these are part numbers that were given to me for the various covers:



Black- 3937121

Plain- 3941775

Red- 3943668



I believe these are DC part numbers.



Confirm before ordering!

DC or Cummins Part numbers... either way I gave the parts guy at Cummins NW in Renton, WA the PN for for the Red valve cover (3943668) and he found it right away in their system... had 1 in stock in Portland, OR. -Ken

Bill, Cummins NW (Renton) should have been able to find it... they have sold an absolute minimum of four of these that I know of (myself, Rob Hanson, Sam a. k. a. DAWG-1 and Evan Beck). BTW, when you receive it don't be alarmed by its looks... the gray color is really a soft plastic type coating they spray on as a means of protection.
