The ball is for regulating the engine oil pressure and should not come out. You may have too much oil in the engine.

I have a 91 heritage softtail thats been sitting 4 a couple of i tryed to get it started as it cranks over im getting oil comming out of the carb???

Hi, Joe it's called "WET SUMPING" most Harley's with external oil pumps if left sitting for weeks or months will eventually let the oil tank contents drain pass the oil pump check ball and fill up the bottom end of the crankcase when the bike is started the excess oil will gush out of the breather vent and if routed to the air cleaner will also flood the filter. This messy condition will continue until the bottom end is forcibly emptied by the flywheels or manually drained if there is a plug. There are 3 options you may want to consider:
1. Drain the oil tank before storing the bike.
2. Replace check ball and resurface seat in the oil pump.
3. Install inline ball valve shut off in the feed line to the pump.

I have a 1990 harley fxr and when you start the engine oil starts leaking out of the crankcase breather what would cause this

This is a common problem with the older bikes. The reason is the position of the oil tank and the type of oil pump the engine is equipped with. With the tank being higher than the engine, oil will seep past the check ball in the oil pump and into the engine. When you fire the engine up, the oil pump cannot pump the excess oil back into the tank quickly enough and some gets blown out of the crankcase vent. If you allow the bike to sit for extended periods of time, this problem is worse. It's commonly called "oil sumping" around here. When you hear an old Shovelhead rider talking about his bike "puking", that's what he's talking about. I've seen those bikes puke nearly a quart of oil after sitting a few months. I've seen Ironhead Sportsters completely drain the oil tank into the engine. This is normal to a degree but if it gets too bad, you can "reseat" the check ball by removing the plug above the check ball on the oil pump and use a small hammer and punch to gently tap the ball into the seat in the pump. Then, remove the old ball and drop in a new one.

Good Luck

The oil dip-stick is blown out of its seat when the compressor runs

Without knowing what make or model you have, check the following:

1. Some, not all, compressor dip sticks have venting holes for the crankcase. If the vent holes are plugged or the check ball is stuck the dip stick will get forced out when the piston comes down.
2. Make sure the oil level is where it's supposed to be. Too much oil in the crankcase will cause the motor to work harder and the excess oil being splashed around the crank case can overwhelm the vents in the case or dip stick and again blow the dip stick out.
3. Worst case, you have worn or broken rings on the piston(s), a hole in a piston or a badly scored cylinder(s) and air is leaking past the piston and creating pressure in the crank case and blowing the dip stick out.

Have oil comeing out of a line that is not hooked up to anything

If you look directly behind the oil pump, you'll see a line of three holes where hoses run to the engine on your Shovelhead. The top hose just above and behind the pump is the breather hose for the primary and oil tank. The next one down is the return hose for the oil that collects in the pirmary to be sucked back into the engine by crankcase vacuum. The lowest hose, and probably the one you are talking about is the crankcase vent hose.

This hose vents the crankcase pressure out of the engine. When the bike is allowed to sit for an extended period of time, oil seeps past the check ball in the oil pump and goes into the engine. This is because the oil tank is higher in the frame than the engine and the ball cannot make a complete seal. Now, the oil builds up in the engine cases. When the engine is started, the scavenger side of the oil pump cannot pump all the oil out of the cases fast enough and it's blown out of the crankcase vent. I've seen as much as a quart of oil pumped out of the cases before it stops. We call this condition "oil sumping".

Put a pan or something under the engine when you start it up. After running the engine for a while, the oil should stop. It makes a terrrible mess though. If the oil does not stop after about ten minutes of running or you get more than a quart of oil out of the vent hose, you may have a problem with your oil pump.

The best way to prevent this is to ride or at least start the engine up at least once a week. You can try reseating the check ball in the pump. Sometimes this works, sometimes it doesn't. Let me know if you need any more information.

Where is check ball valve on my 1982 electaglide

The check ball valve is in the oil pump. When you look at the top of the oil pump, the check ball is under the innermost threaded plug, the low one, not the high one. You will have to drain the oil tank before you remove this ball. Take out the plug, the sping, and use a magnet to remove the ball. Buy two new balls, they aren't expensive.
Now, drop on of the new balls into the hole. Take a brass drift and a hammer and gently tap on the ball. This will reform the seat that the ball sits in. Remove this ball and install the other new ball, spring, and threaded plug. Refill the oil tank.
Then, remove the crankcase breather line from the rear of the air cleaner. Plug the hole in the rear plate of the air cleaner. Purchase one of the small breather filters (/V-Twin #40-0352) and put it in the end of the crankcase breather hose and relocate the breather underneath the bike.
