Are you sure you aren't talking about the chain oiler system? There is to be a small amount of oil to lubricate the bar and chain.

My Craftsman chainsaw model 316.380200 20" 46cc automatic oiler system does not appear to be working when saw is operating. Also, all oil leaks out of saw when not in use.

take the bar off and remove the chain you will see 2 holes at the base of the bar near the sprocket end
the oil is pumped into a slot that one of those holes cover
from there it moves up a very small slot that is in the base of the groove that the chain runs in
that slot gets blocked by saw dust and prevents the oil from being picked up by the chain guide teeth and lubricating the bar
how to fix
get something like a small paint scraper and using a corner edge clean out the groove around that hole and use compressed air to blow out the debris

My stihl ms390 chainsaw leaks bar oil, so i put a threaded plug in the hole, and when i get the plug far enough in, it impedes the oil flow to the bar.

Take the bar off and clean all the pieces and parts where the bar mates to the motor. Make sure the hole on the side of the bar, where the oil gets onto the chain drivers, is not plugged. Make sure there are no burrs, on the edge of the bar from chain wear, which will push the bar away from the chainsaw body leaving a gap for oil to leak. If your bar is worn, most bars can be flipped over and used either way. If it is made to be used in on either side it will have a hole for the oil to get into the bar on both sides. Alternating or flipping the bar will make it last a lot longer.
Something else to check is if your saw has a breather hole and if that is what is leaking or it is plugged and is not allowing the tank to breath. Not all saws have this feature.
When you store your saw it is best not to store it on its side with the bar hanging down as these position will cause more oil to leak.
Even if you have a perfect fit/seal, between saw and bar, oil will still leak if it is stored in a place with temperature fluctuations. This happens from the oil expands, when it warms up, creating pressure in the tank causing oil to leak out. I always put a piece of cloth on top of a plastic base to prevent seepage onto any surface. I run chainsaws professionally for over 35 years and they all will leak when stored in place with temperature changes. Some are worst than others. Hope this helped.

I have a husqvarna 55 rancher oil comes out the oil hole when bar is not on it but i put bar and chain on and it dosent get enough oil on chain just a small amount between teeth, ive cleaned bar and chain,...

The hole in the bar pad is the breather, it is quite normal for it to leak if the bar is removed, it consist of a role pipe and pipe inside the oil tank, there is nothing to worry about

Bar oil leaks when not running. Why?

Why worry about it? It is much more important that it oils than that is leaks.
Just empty it when not in use.
Bar oil is free if like most people, you just use old engine oil.
The chain may have rubbed and enlarged the opening, but if it does not drain too fast, more oil is much better than too little.
There usually is no mechanism involves, just a small hole.

It would appear that you must 'go under the cover'. Look for a damaged oil line or split oil tank. The oil pump may have come loose from it's mounting. Be sure to check the oil filter for plugging. Hope this helps!

I have a poulan pro chaisaw leaking bar oil from the bottom

Remove the bar and chain. Clean the oil port on the side of the engine and inspect any seals for damage. Start the engine without the bar--it should ooze out oil when engine is running fairly fast. If ok, clean the oil passages in the drive end of the bar--particularly the small passages that lead from the large holes into the chain groove. Clean the entire groove and make sure the end sprocket (if equipped) turns freely. Reassemble the bar and chain--tighten the tension until the chain does not droop from the bar bottom (chain cuts toward you on the bottom run), and yet moves freely by hand. Hope this helps!

Oil is leaking and burning when chainsaw is on

Hello Jimmy;
On an electric I cannot visualize anything getting hot enough to burn oli except the bar and chain. I am hesitant to get 2 deep into any repair, I fear it may be used to negate your warrenty. Try The first part of this and reply (below) about oil seepage with bar removed please. Is the model number a ZR10926?
Oil System Plugged:
  1. Remove the clutch cover, bar, and chain, clean the bar groove, any holes and passages on the rear of the bar (both sides, consider rotating the bar), if equipped with a sprocket nose ensure it rotates easily at least one complete revolution. Clean the saw oiler hole and channel. Insert a blunted, hooked piece of wire through the oil filler hole and pull the hose in the oil tank out. Pay attention to the screen or filter on the free end (clean or replace, difficult to determine serviceability). Start the saw and see if it oils when revved up (oozes down side of saw). If yes reassemble your saw. If no, continue with 2.
  2. Work your way through the linkage (use IPL to identify components and locations) cleaning and replacing any defective parts as you go. Carefully check the hoses for cracks especially at bends and connections. If equipped with an oil pump it is usually behind the clutch (clutch is a left handed thread). Please make extensive notes & some digital pictures will help during reassembly.

Please see your manual for bar and chain installation.

Flymo 2200 chain oil leak when machine is running

That chainsaw should leak oil off the bar. A small amount of oil flipping off the chain is how it is suppose to work. If it is a large amount of oil dripping from near the sprocket then you probably need to do some cleaning.

Remove the housing that covers that bar and sprocket. There are two plates on each side of the bar that set over the studs.They may be identical or slightly different depending on the saw but at least one of them will have a hole in it for the oiler. If you remove the bar and both plates you will see the oiler hole on the saw housing. This oiler injects oil through the plate and into a small hole in the bar where the chain picks it up and carries it around the saw. If this hole becomes plugged with sawdust it will keep your saw from oiling the bar proplerly. This hole should be cleaned out periodically. It's not a bad idea to remove the whole chain periodically and clean the chain guide all the way around the bar and get any sawdust buildup out so the oil can flow better.
