I have a 1969 Kargard tow behind compressor gasoline 4 cylinder Continental Engine.

The engine runs well , but my major problem is that there is compressor oil spewing out of the intake air port on the compressor. I have no idea where to add oil or change the oil or the oil level , there is no sight glass .

I have been looking on line at e bay and found a service manual for the Continental Engine but cannot come up with anything for the Kargard Compressor anywhere. I suppose it is going to be difficult being build in 1969.

But I will continue on until I can figure out the problem !

I would take it to someone but I do not know of anyone in my area that repairs compressors of that vintage !

I will keep calling around !

Spewing oil and how to check oil level ?
by: Anonymous

I tried to add additional photographs and a video of the compressor running and could not do it !

The compressor starts and runs well but it is spewing a lot of oil out of the air intake and getting all over the engine. I did pull the air cleaner off and looked down into the large pipe and could see oil under the open butterfly .

I would appreciate any help I can get to resolve this oil issue !

Thank you in advance for any and all imput !

Kargard additional comments

Thank you Doug for the input .
I will take a couple more photographs to see if what you are talking about exists on my machine .
I am still lost regarding the oil level and where to check it , maybe with the additional photos you can figure it out .
Does the unit look like a rotary compressor to you or a vane compressor ?
Thanks again for any input !

Spewing oil and how to check oil level ?
by: Brian

I very much appreciate you taking the time to comment. So I took a look at what I believe to be the unloader valve on the intake and it does move when I fire up the motor, but I still have lot of oil spewing out of the pipe that sits below the air cleaner intake .
This is a nice machine if I can resolve my oil situation.
When the machine did run , I connected the jack hammer and also had a tone of oil coming out of the hammer !
And we both know what happens when you run anything without oil .
Anyone else have any ideas ?
Thank you in advance for any reply!

Kargard oil
by: Doug in s.d.ca.

I'm guessing a bit, but looks like it's either a screw or vane pump. So, there probably a vessel somewhere after the pump, which serves as the separator - getting oil out of the air. That's usually where the oil goes in as well as the level gauge. If that is there, it doesn't appear in your pix.

As to the oil coming out the intake, that's your load (intake) valve not closing when the pump tries to unload when the pressure gets to the unload setpoint. It's usually two parts - one to stop air getting in, and another one to stop the oil getting out.
