Default Penberthy Oiler Issue

I just picked up a 1 1/2 hp Stover hit & miss, and it runs great, but I'm having trouble with the Penberthy oiler. The oiler drips just fine, until I start the engine. With the engine running, the oil stops dripping. As soon as I shut the engine down, the oiler starts dripping again.

Do I have some kind of blow-by issue??

Thanks,

- Bill

see attached pics showing the oiler I have.

cylinder oilers have a check ball in the base that keeps the cylinder pressure from blowing the oil back up into the oiler. If yours doesn't have one, then that is more than likely your problem.

Strange, I've had the oiler apart and can't see where a check ball would even fit...make sense what you're suggesting though. Thanks.

Oooops! I just found the ball check -- at the base of the sight glass. Seems to be nice and free. Any other suggestions?

make sure that it is free of any junk that might prevent it from seating. You might even try opening the needle valve a little more when the engine is running, and see if that makes a difference.

It is completely free from junk, but I just noticed that, the ball is resting on a cross-pin, keeping it off-center (see pic below - it is taken straight down the lube tube), which is allowing blow-by. Is that pin normal, or is there supposed to be a real seat of some kind at the bottom of the ball?

I believe it should seat when the compression blows it up against the top.They don't seat in the bottom or the oil can't get past.I take the ball out, and drill 3/16 in the coupling on the down pipe under the oiler..Works fine for me.

Yes, Dick, it seats when compression blows the ball up. However, the ball is not getting blown up. I can barely feel any pressure blowing up the tube when the engine is runnig. Plus, the ball is maybe 1/8" below the upper seat, and I don't think the ball can get blow up that far with such a small amount of pressure. Also, I can see the oil reservoir bubbling as I would expect with the ball not seating.

looks like a home made cylinder oiler. Ball is to far from set & looks like steal witch would make it to heavy, a little copper ball is best for that application, it all so needs a vent tub.

You're right about it being a heavy steel ball, Roger. I'll try to find a smaller copper ball, although I have no idea where to look...

Also, can you tell me more about the vent tube?

Thanks,

Bill

I have several engines with machine oilers on them (no check ball) I do just what Dick said but with the hole drilled on a slight angle upward it helps to keep the oil from dripping out of the coupler into the hopper.

I'm not understanding exactly what you and Dick are suggesting regarding the 3/16" hole drilled in the coupler. Where in the coupler is the hole drilled, and what does it do?

Thanks!

My oiler pipe needs a pipe coupler threaded on it for the oiler to screw into.I drill a hole through the side of the coupler.What it does is let the back pressure or blowby escape instead of blowing up through the oiler.All my engines are set up like this without any problems.

I drilled the "vent" hole, and it worked GREAT! The final question is...what is the recommended drip rate for the oil?

Glad it worked. I set to 3 or 4 drops of # 30 non detergent per min.
