original engine and crankcase ventilation

Two questions: Just got a 1960 3B in need of much restoration. I have many concerns, questions, and little knowledge. There were three owners before me: the military, a railroad, and a man who abused the heck out of the jeep. My two questions, here, are: (1) “Does anyone know, by looking at the photos, if this motor appears to be configured in such a way that it would lead you to believe it could be the original engine installed in this 3B. I have a receipt for a $500 rebuild in 1989, which could account for the unoriginal blue paint. Also, I’ve been told that crankcase ventilation is proper, but I can’t see that is the case. (2) How and where is the crankcase ventillation proper, original? It doesn’t look that way to me. I believe there should be a vent tube on the oil filler, but that’s a guess based on nearly no knowledge.
Thanks,

Greg

Greg,
Oh Lord, where do I start. First and foremost, this website has an incredible amount of information on it. But, if you are going to work on your jeep, you need a Service Manual. It describes how everything works and how to service all components.

Now the engine number should be checked to see if it fits with your year make.

Look at the links and then study the engine photos for your year group.

There are alterations I see concerning your plug wire retainers (they look fabricated) and the throttle linkage spring is not right either. And please get a sturdy battery hold down before you have another problem. Looks like the hood hinge has had a few alterations also. There may be more but that's what I see.

We've covered the PCV systems here several times. Unfortunately, I can't see what you have as the pics don't go down far enough to include the exhaust valve cover.

You can use the Search function up at the top to see some of the other posts concerning PCV set ups or read here:

Study here, read your Service Manual and we'll help where we can.

Can you supply a close up of the upper portion of the oil filler tube ?

The accordion hose from air cleaner to carb horn is collapsed in the middle. Possibly choking the engine for air.

If you're lucky, a temporary fix:
loosen the clamps at both ends of the hose
don't remove the hose from either fitting
just rotate (twist) the hose 180 degrees in its clamps so the collapsed part is now on the outside of the bend - it may stay opened up
if not, replace - but beware, most of the reproduction hoses are rubbish, they either split or collapse as you're trying to install them.

That's not the right carb either

sorry I haven't replied, yet; new to this forum stuff; thought the only time someone responded would be when an email said I had a response.

I'll supply better photos.

As far as me not having the right carb; I know it's not the right carb, but I don't know what the "right" one is. Just saying it's not right isn't a whole lot of help. How about telling me what the "right carb" is.

fixing the accordion hose is a good idea. If you have a good one, where did you get it?

The main way to determine if the engine is original to this particular Jeep is via the engine number.
Please identify the engine number located on the front of the engine block above the water pump and below the head.
If the number is not visable it indicates that the engine block was "decked" (milled for flatness by a machinist)

I don't have one.
The P.O. threw away the hose and air horn, replacing them with a little hot rod air cleaner sitting on top of the carb.
See it here, about half way down the page:

Lame.

I'll do what's suggested and describe the results. Thank you.
