Just got back my M38A1 motor from a complete rebuild of the motor. Few questions, the shop put the wires back on and from what I think I remember from this site, the sequence is not what you typically find on the web. I can where he put the wires if need be if it helps. 2) The bushings on the starter bracket are dry rotted and going to replace those, any place better that Willy's to get those or any part better than others? 3) Paint, since the motor was cleaned and then reassembled should I paint it. They reassembled it with starter and fuel pump and such. Would it be worth the time to paint it. They stated they seen jeep that the Army just painted everything. Wires and connectors and such... Ideas? Help. Be kind I'm new to putting this together..

M-38A1 motor colors are as follows (Or Close to) - Valve cover is Black with the yellow decal on front corner. Starter is Black. Distributor is black also if I remember. Generally fuel pump and carburetor is natural with a coat of natural paint (Old time Carbs were done in this cannot for the life of me remember the coating) Rest of motor is color of the jeep. I also went one step further and painted the exhaust manifold brown to keep the rust down...
On mine I left all the tubing natural as I used Nickel-Copper alloy lines (look copper colored) Spark plug wires were left black unpainted if original military.
I am not an expert and it is your jeep do with it as you see fit. The above are MY interpretations of the photos found in the manuals and from seeing other jeeps I liked.
Good Luck... _________________ Hal, KB1ZQ

The engine rebuilders that really know the L134's and F134's know how to do the very preliminary basic distributor to oil pump to cam timing set-up. They are also aware of the distributor end of the plug wires occasionally not correctly illustrated in manuals. This distributor to oil pump to cam timing is the key to enjoying your first start up or working your butt off and pulling the rest of your hair out trying to figure why it won't start or runs so terribly. Most engine overhaul shops are more familiar with engines that had distributors driven directly by the cam. The Willys setup is much more un-common . So I suggest you discuss just how the engine shop went about the timing of the distributor during it's installation before you try starting the engine.
