'49 willys Go-Devil motor

hey guys.. picking up a willys w/ this mill this weekend.. anyone know what weight oil you're suposed to use?
what about gear oil for the diffs (timken axles), TC (ATF i guess??), and the tranny (T-90). what about the fact that it was designed for leaded gas? what do i do about this..

wondering about the synthetic oils and how they would work in the motor once it's rebuilt...


Awwwwwwwwwwww... So he wants to go OFF-ROAD does he????

Ok, I've got my "older than God" manual out.It does'nt list a "Go Devil" motor, however there are only options.The 134" 4cyl "F" head and the 148" 6cyl(also a flat head design).According to the manual 20 wt is recomended, however this manual was printed in 1951,long before ash based multi-gtrade detergent oils were around. On a rebuilt motor with the proper clearances a 15-40 or straight 30wt would be fine. As for synthetics, personaly I don't feel the advantages out weigh the cost for the avarage driver.Your question on the boxes. no ATF here, straight 90WT in everything. As for leaded gas, you can install hardend valve seats if you want, but I don't think there is much of a worry. If you need any engine data,E mail me with your list and I'll give you what I have.

jeepdaddy pretty much covered it.

I am a fan of the 20W-50 oils (I'm sure everyone knows by now, LOL!) or 30W. But, as jeepdaddy mentioned, the 15W-40 would be a good break-in oil at first. Wouldn't recommend synthetics in that motor.

Let's face it, synthetics are OK if you're running a NASCAR or Indy Car, but no daily driver really needs it, LOL. Do the math on the $$$ difference, and it'll blow your mind. Nobody blows motors because they use dino oil instead of synthetic, LOL. Motors go because of poor maintenance, pure and simple. <img border="0" title="" alt="[Wink]" src="wink.gif" />

I think the Go-Devil motor is a cool motor, keep it, and rebuild it, it's a novelty, as is any Jeep! And parts are NOT hard to find, it's a very very common motor, parts availability is fine.

However, as far as the gas goes, rather than spending big money on the good lead substitute, I would use hardened valve seats also, since you will be rebuilding it anyway. They will burn out quicker if you use regular ones and dont use the lead substitute. The substutute is a pain...much easier to pull up, pump, and go

I'll check my book to make sure, but i believe it is the other way around evil....F-Head was the first generation 134 with valves in the block, L-Head was the second generation 134 with valves in the Head. I'll check later in my book to make sure. I have some really good Jeep History Books <img border="0" title="" alt="[Wink]" src="wink.gif" />

yeah.. the go-devil was originally designed by the overland company.. and willys merged with them pretty much to get that engine because it was so reliable. the L-head was the engine in ALL of the original WW2 willys jeeps..

Sorry, I was suffering from a case of lysdexia

Just checked the book, the L-Head WAS the first one. Sorry evil, had to see for myself, I was so convinced the F was first for some reason (F for "First", LOL, I dunno!)! I was having brain-farts! LOL <img border="0" title="" alt="[Wink]" src="wink.gif" />

hehe yeah.. the F-head many people falsely believe that came about due to ford's part in building the GPW durint WW2 as a secondary plant.. f=ford is not true.. F just happened to be what was stamped on the head bolts on the motor... thus "F-Head"

The F-Head was definitely an improvement over the L-Head, for both the 4 and 6.
