m16a223,
Can you relate exactly WHERE oil is coming from on the gas cylinder?? My initial answer to this question would have to be "no, it is not normal". I say this because the there should NOT be enough oil in or on the cylinder to cause a noticeable "leak".
Cleaning-lubing procedure for the gas piston - cylinder is to very LIGHTLY wipe the op-rod and piston with an oily patch. Same for the inside of the gas cylinder. The purpose of lubing these parts is NOT to provide lubrication, but to prevent rust during storage. They are designed to operate in a dry condition.
In any case, there should not be enough oil in there to "leak".
Re loading procedure....
Insert a loaded 8 rd. clip into the clip slot. With the right hand flat along side the action, the back edge of your hand in front of the op-rod handle, press down on the upper cartridge with the thumb. Press the brass between the top edge of the clip and behind the shoulder (DON'T press the edge of the clip or back at the base of the cartridge). Firmly press until it bottoms and you feel the clip "catch" in the mag well. As you release pressure with your thumb, the bolt & op-rod should release and want to fly forward. The edge of your hand is preventing it from closing. Quickly pull the thumb up and clear of the bolt, and at the same time rotate the fingers forward and up, letting the op-rod handle ride under the edge of your hand and close. Don't try to "ride" the handle home as it may not fully close (also, your thumb gets "ridden home" as well. painful). As the handle clears the edge of your hand, let it SLAM the bolt closed. This is how it is designed.
Note: Many Garands, when you remove your thumb and hand, will remain with the bolt open. If so, you probably noticed that the bolt came forward about a 1/4 inch and stopped as you pulled your thumb free. This also, while not the designed operation method, is normal for many rifles. No big deal, and nothing to worry about. If this happens, just firmly whack the back edge of the op-rod handle with the heel of your right hand and it will close.
Also note: I'm no M1 expert, but I does luv'em so....
For advice from the real Garand gurus, go over to the Culver's board. That's where ALL the REAL experts hang out. More info on M1's than you can shake stick at....
