Engine colors?

What colors were the engines?  I thought I read where replacement engines were all one color, maybe grey?  Mine is rust primer color with a red water pump.  Just trying to figure out which way to go.  Thanks.

OK, thanks for the info.  Anyone want to post a picture on this thread of your engine bay with your traditional or non-traditional color choice?  I should paint my engine red as I am sure it is not original, but I am more partial to orange or grey.  Help me make my decision.

  If your engine is not original to your jeep but not a 4LR, it likely came out of another jeep in a wrecking yard or other source. In that case it would likely have been black, as it was the original to the jeep it came out of. But guys like you who like another color may have painted it at the time of installation. Also, lots of independent rebuilders had their own favorite color that they put on everything that left their shop.

Nice. The engine in my red jeep is primer gray. It is a replacement and I don't like the gray, I think I'll go red.

Did the GPW engines have Ford script on the head?

The Pueblo Army Depot didn't care what kind of head when back with what kind of block, and vice versa. Yours could be a GPW Block with a Willys head.

And what does it say?  SE Kansas 46 CJ-2A is correct the depots did not care about matching MB and GPW parts during rebuilds.  At the end of the war to help Germany and the other European countries get back on their feet the US set up rebuild facilities, hiring the local civilians to rebuild the various soft skinned military vehicles.  I recall seeing pictures of piles -- literily piles of axles and other drive train components that were awaiting rebuilding and re-installation during the rebuild process.   I suspect that if the block was a depot rebuild the serial number would be behind the oil filter.  If it is, does it start with a GPW or an MB?  The MB engines were painted OD.  It is my understanding that the reason the Ford engines were painted gray was that Ford built them in the same factory that made the engines for the Ford 9N tractor, that were also painted gray and when the started building the GPW engine they just painting the gray.  Hope this helps.
