A small brass drift is probably better. |

Put the correct size socket on the end of the oiler and back it out. (Lefty Loosey) The correct size hole in the oiler should be .040" or the same size as a #60 drill bit. Replace the oiler in the block making sure the oiler points to the space pointing between the where the two timing gears meet. A SMALL amount of #2 Permatex wouldn't hurt anything if placed on the oiler threads and NOT in the female threads of the block.

Thanks again SE Kansas! I will remove and check the oiler this evening. Thanks again to everyone who gave their two cents to help me get this done.

If the gasket has a round hole and you want it to be lemon shaped you can trim it with a sharp knife or scissors.

Thanks Oldpappy about the gasket information.
My crankshaft oiler has an orfice size much larger than .040 (#60 bit). It is very close to a #50 (.070). Looks like I need to try to source the correct part.

Or braze that one up and drill a smaller hole.

I appreciate this post. I'm going to change from a pickup truck front motor plate to a 2A plate. I felt through the 2 holes and the flat area the inside puller has to engage is not much. Like 1/8 inch of flat. When the engine is together and you pull one of the timing gears off, there is tension due to valve springs etc. I have ruined cam gears myself since the spiral action against the tension can get quite stiff. I plan on re-checking valves and installing a new copper head gasket that I now use instead of fiber. (I hate the felpro steel one sided SOB). I'm pulling all the valves, head, springs, distributor, and installing a new oil pump. I will pull the cam out and bypass all of your pain. I built this engine and it's on the stand still new. I can flip the engine over and let gravity keep the tappets out of the way of the cam lobes. Much easier to do this all while out. I'll also check my valve face pattern with Dykem and lap if necessary. I sure felt pain seeing all your pictures. Good part is you will win this project.
The other thought is offer BW cookies and a HBR to come and pop the gear off for me-------LOL PS----if you were to pull the valve springs and keepers, on a assembled engine, make sure and stuff rags in all the side chest drain holes so the keepers don't fall down into the camshaft or oil pan. ask me how I know this.

Ok, I'm finally ready (3 months later) to reinstall the oiler and the time has come to deal with the too large of an oiler orifice issue. My only brazing tools are for copper plumbing. I have MAPP gas, not oxy/acetylene. I also have a mig welder. I'd appreciate advice on the best method to fill in the hole, before I drill the correct size hole. Thanks!

You could tap it for a threaded plug and just drill another hole in it or on the next flat. I would probably use the mig and weld it and redrill it.

Screw in an 1/8” pipe plug and forget about it 😎

What? Really? Not needed to oil the cam and crank gears? ... but that's not what the TSM says to do?

My old engine ran for 30 years with none of the above issues, new motor has ran for 4 years with no issues, the old timer that showed me this trick has done it for decades with no issues, not saying it’s right, but it works 😬 Lee |

Some believe that the purpose of the oil filter draining into the front cover is to lubricate the timing gears. While I don’t agree that it’s the primary reason for the drain being there, it probably would do a good enough job.

I am with Bruce on this. I believe that the Willys engineers thought that since the oil has to get back into the sump, why not put it to use? It may as well lubricate the gears on the way to the sump. The oil filter was an option in the early CJs. On the few I have seen that have no oil filter, there is no line feeding a nozzle to lube the gears. Does it make a difference? I doubt that any of us would notice any. However, if it is possible, all of my rigs get an oil filter, since the filter does make a difference, so I will never know.

Just my 2 cents. Somebody ought to say it. The manual says that .040 oil jet fitting is directly related to proper oil pressure (lubrication) for the #1 connecting rod bearing. The oil filter return line has zero to do with that conrod bearing. The .040 jet squirting the crank and cam gears might seem incidental (or overkill with the oil filter return line), but it seems to me the Willys engineers knew what they were doing by putting it there for the conrod bearing in the first place. And if they discovered it wasn't needed, wouldn't there be a service bulletin saying it was ok to plug? Plugging the hole might be good luck for some folks and run for miles and miles and years and years with no trouble, but I'm not one of them. It's a $10 part, not expensive to have it there, and not hard to find one or re-drill the orifice to .040. Plugging it off seems needless for no apparent reason other than lazy? I bet back in the day when the jeep motor was new if you plugged it you'd void the warranty. And if the oil filter was an option not taken (or somebody removed it) --- and the oil jet hole was also plugged --- what would lubricate the crank and cam gears? Good luck? Perhaps the real reason it's there is just for that case, we'll never know. Until then, I believe it's there for the conrod bearing. It'd be interesting to find out if any professional engine builders experienced with Willys motors would say plugging that hole is ok or is something they'd do.
