Just got my first jeep from my grandpa hasn’t ran in over 20 years any advice on getting started will be greatly appreciated. My plan so far is to see if I can turn the engine by hand if so drain everything put fresh in and see if see will run. I am open to all advice I know very little about these machines

Welcome to the madness Danny. I think you are on track, if it turns over change engine oil & filter and I would also drain the transmission oil. Use GL1 in it. if it was sitting outside the rain water will run down the shifter cane and fill the trans. with water and rust all your gears and bearings. you can just pour a little gas down the carb and if it fires then you will probably need to remove the carb and rebuild it. good luck and let us know how it goes. post some pictures so we can see her.

as said above i would drain the oil. Then buy a quart of Marvel Mystery oil and pour the whole quart down the spark plugs holes in evenly. let it sit for a couple of days. get a 1/2 drive ratchet long extension and a 1 3/8 socket put it on the lower crankshaft nut and start rotating. don't expect to get it to rotate to much unless you are lucky. inch by inch. as you have time drain all fluids . the above service manual is a good one go find it. just general advice, the more you modify the Jeep from original the more you are subtracting vales of the Jeep. best of luck |

X2 on the Marvel Mystery Oil. That stuff works wonders. When I got it home the engine was stuck. First thing I did was divide a bottle of Marvel Oil poured into each cylinder. I let it sit two weeks, and then put a wrench on it and it moved a little. Let it sit a few more days and it moved some more. Another few days and it would turn all the way over with the wrench. While the Jeep was soaking up the Marvel I put a kit in the carburetor. I went out every day and turned it with the wrench until it turned over freely. Then, with the plugs out I tried turning it over with the starter for the first time and it spun over real good pumping out a lot of the excess Marvel oil. Then I drained the crankcase and refilled with a mixture of 30 wt and another bottle of Marvel. I installed new plugs and the carburetor. Hooked up a boat gas tank the the carb and tried to start it. It spun over good but would not fire. So I installed a new set of points, condenser, rotor and cap. Then it showed signs of life. Within a half hour I had it where it would run smooth at idle, and boy did that ole gal smoke, mostly burning off the Marvel oil. For a couple weeks I went out and ran it for about 30 minutes at a time. Each day I did this the smoking would be less. It now runs very good and no longer smokes a bit. I am lucky with this one as it only has 33K miles on it. The previous owner's son said the Jeep was parked due to using oil. I think the only thing wrong with it was the oil rings were stuck due to carbon build up. The Marvel Oil does a good job dissolving the carbon and I have used it for years on engines thought to be in need of a rebuild. It will work wonders. However I have started many simply by taking the top off the carb, spraying some carb cleaner around, cleaning the points and hooking up a boat gas tank to avoid the old gas and crud in the fuel system. You do not want old gas spraying around, so you want to disconnect the fuel line to the pump. A Jeep that has sat a long time will likely need a new gas tank, but if you are lucky the old tank can sometimes be cleaned out. Last year I cleaned the tank on my 47 using "The Works" toilet bowl cleaner and water. The tank cleaned up nicely but the cleaner dissolved all the rust and left pin holes in the bottom of the tank where it was about to rust through. After that I just replace the tank, lines, fuel pump, and do a carburetor rebuild to get it to run right as SOP.

As the cylinders on the Flathead 4-cylinder are not below the spark plug holes, you need to use a tube or something similar to get the MMO to the cylinders

Doesn't hurt anything if some of it gets on the valve heads might even be good if it does. Pouring it into the plug hole will get it into the cylinders. Where else could it go?

Bruce of course is right. I didn't think about that. It will get into the manifolds on the open valves and will smoke like crazy on first fire up, but on the other hand the valve guides may get a little dose of the MMO.
I suppose it would be better to use a hose to get past the valve chambers. The one I was using it on was an F head, so a bit different situation.

Just because you get it turning over doesnt mean you will have enough compression for it to fire up. My 46 was frozen up and I got it rotating but a couple of valves were stuck in the guides and I had zero compression after spinning it over with the plugs out using a gauge. Ended up removing the head to get the valve stems freed up. Turns out the rings were stuck in the pistons and had to be removed... I did an in frame rering to get it running.
