I have a Poulan Pro 380 that is leaking bar oil.I can fill it with oil and it will leak out during the night.

Is it really leaking or just oozing down the side of the bar and engine block due to a totally crud-filled oil slot in the guide bar?? I'd suggest pulling the chain and bar and inspect the oil port of the pump discharge and the slot in the bar that aligns with that port. Either or both could be impacted with sawdust not allowing oil to enter its proper path.

sounds like the small oil feed pipe inside oil tank as come away from the end. just push it back on you may need a pair of long snout pillers.. good luck

try and run it with the muffler off the build up with carbon and restricted the exhaust flow as for the oil leak mine the screws became loose behind the clutch for the oil pump

Yes, mine does that, too. It's seepage that gets past the oiler mechanism by gravity; not because anything is broken. The easy way to stop it is to store the saw so the gas and oil fill caps are facing down. No more seepage! Of course, you need to ensure that the fill caps are snug.

if its leaking out the bottom were the bar goes in too the chain saw this is normal this is the bar lube oil its thicker that regular oil and sticky U should have a screw plug marked lube for this

The easy fix is to drain the oil tank when not in use. Many saws will leak some oil initially, but should not continue to do so. If it is making a large puddle, oil is getting past the oil pump which may be worn from long use. Make sure the tank vent is not plugged as heat from the engine can increase pressure in the tank thus forcing oil out. Hope this helps!

It is the nature of the beast. Many chainsaws suffer from this malady. I own a bunch.

Try loosening the oil cap prior to bed.

It's a seal somewhere either on the reservoir, or the 'feed' to the bar.
But in the short term, if you must use it, the simplest way of stopping the leak, is to not store it with any oil in it, until you locate the source of the leak.
That should help, but I'll wish you good luck never the less ;)
& plz don't forget to rate, thankyou :)

Hello there. Regarding the bar oil, many loggers plan their work so that they are out of bar oil at the same time that they quit for the day because bar oil has a tendency to leak. Another method that has some success is to mix your bar oil with a heavier oil but the trade off might be less lube getting to the chain when you need it.

Regarding the chain moving in idle, this is another common problem. You can usually slow the idle down until the chain stops, as you indicated, but I too have had chain saws where I finally just decided to live with it and be extra attentive to what was going on.

there is some debris blocking from entering the bar and when sits it seeps out,clean bar and are under chain cover
