 One of the three types of constant velocity joints used in the jeep during WW2 is the Rzeppa. Rzeppa is pronounced “sheppa”.  For more about the inventor of the Rzeppa constant velocity joints, see http://www.the-crankshaft.info/2009/09/universal-joints.html.

I thank you for your military service. You can obtain copies of your military records...

This post isn’t really about military vehicles but some may still find it helpful.

The vacuum gage can tell you much more then a simple compression check.

See How to Master the Vacuum Gage

You may not have a port on an early manifold. Army Motors told the troops to drill a hole or the vacuum part. And I reckon to tap it for a plug as well. As an alternative you could fashion a spacer with a vacuum port for those jeeps that don’t have a port…and when you don’t want to drill a port.

[1] Make a thorough inspection for leaks. Check all oil lines, and tighten connections or replace as necessary (par 204).
[2] Poor driving practices may be responsible and should be corrected. Speeding the engine will result in excessive oil consumption.
[3] Worn pistons or broken piston rings area common cause. Make the compression test (par 9).
[4] 0verheating may be a cause (par 89).
[5] Clogged crankcase ventilator may be a cause (par 207).
[6] Loose connecting rod or main bearings may be a cause.

Oil bath filters are effective at removing dust and dirt from the air used by the engine.  If the oil bath filter was really effective then why did the automotive industry give it up for most if not all applications? Was it just too messy or not green enough for today’s world? 

Which version you choose  is not really all that important both filters work very well under most situations. It’s a personal choice that has no visible impact on the jeep.   It’s a great idea and can be environmentally friendly for all you tree huggers out there.

Some of these folks that pooh pooh the dry air filter are the same ones that tell you to use silicone in the brakes. One modern idea is bad the other isn’t? Neither one can be seen.

Don't try doing this will an oil bath filter! Your jeep fender will get an oil bath.

Besides if I spill my dry air filter on the fender it doesn’t leave any trace. Trying doing that with a loaded cuppa oil. 

I’ve been running my dry air filter for 25 years and it works great. Why did I do it? Well, because I used to drive my jeep in sub-zero weather. You can’t have oil in the oilbath filter in sub zero weather. You are supposed to drain it and run with it dry. How effective can that be? So I converted and haven’t looked back.

The dry filter cartridge easily goes into the cannistor with the steel adapter.

The adapter I use was made/sold by USM back in the early 1980s.  It’s long out of production.  A friend of mine made a limited production run of adapters made from plastic.  These proved to expensive to sell for a resonable price.  But have no fear some clever folks have figured out how to make an adapter for parts of your toilet!  Yes, the doughnut ring can be used for something else besides a toilet.  The added benefit is that these rings are pretty cheap to as compared to the steel or plastic adapters.

The website 1945.com has an interesting article about using these doughnuts in your oil bath filter.  It’s a great article and worth the read if you think that global warming is caused by using oil.  Hey, every bit helps, right?

People have spotted a lot of issues on my jeep over the years but not one spotted the dry air filter!  Don’t tell the jeep police!
