stihl 025 oil leak

[Kenneth F]

My saw leaks oil when turned up on its end(the bar toward the ground) something serious where's the vent/breather at it looks to be from under the muffler close to the bar looks like the vent is back there oil is pouring out of that oil I'm pretty sure that's where all of its coming from

The plug has come out of the end of the oil passageway that leads up from the pump to the bar pad, this is common on the 021, 023 and 025 saws. I have replugged 5 of these saws that I have come across, the plastic plugs just fall out likely from the heat held in this area from the muffler and heat shield. I cannot find a replacement plug part number for them from Stihl so I make my own. The plug cannot be driven in any more than 5/16" or it will block the oil port that delivers oil to the chain bar. If you look down between the muffler and the back side of the bar pad you will see what looks like the open end of a tube facing up, that is where the plug is supposed to be.
The oil tank vent is actually found in the bar mount pad between the two bar studs. Its part number is 1128 690 9100.

That's the plug or vent I was referring to. They're typically orange in color. At least the ones I've seen

 

[Kenneth F]

What are you making them from I'm assuming it'll need to let air to vent

When I get to the shop I will look up the plug part number. It blocks a passage that is left over from the plastic forming that is required to get the details of the casting correct.

Yes they are but they are a solid plug not the tank vent. The tank vent is found in the bar mount pad between the bar studs.

I have checked all through Media Cat and cannot find that plug as a replacement part. I even called my dealer but unfortunately my main parts man is still off on holidays. I tried to find that plug before but came up with nada so I just make one to fit out of aluminum, just turn it with a slight taper and tap it in, very little depth there as it will block the feed passage out to the bar.

The oil plug is located here. It's the orange deal in the middle of the circle. They will sometimes fall out. When they do Stihl recommends using part # 9134 381 1230, which is merely a 6mm allen screw, to fix it. I thought I had some onhand so I could measure the length, but I don't. They recommend coating the screw in Loctite 262 and screwing it into the hole, leaving 1 to 1.5mm of it sticking out. If you go too deep you will block the oil passage. They also recommend that the screw might split the plastic, so tapping with a M6x1 tap is advisable.

I can't find it in media cat anywhere either. I had to go back to one of my training manuals.

I understand that. I shouldn't have used the word "vent", but instead "plug"
I know where the "vent" is.

Thanks for looking,Doug. I have looked more than this one time and don`t see a thing for a replacement. A threaded in plug would work well as long as a sealer is used but again there is little depth there to run a threaded plug down very far, a little metal could be ground off the end sort of like a 45 degree bevel to extend one side of the plug in a little further but the side that was ground out would have to face the bar pad side.

I was attempting to get everyone aligned on the terminology since there is a difference between the two and its quite hard on the network to get the meaning across if everyone is calling the part a different name. One thing I have learned from being on here for some time now is that its better to get as many terms straight before the OP gets really confused and just drops out before we get a good chance to help out.

I just purchased a used 025 and there is oil stained on the muffler and it has let quite a bit on the ground since I took it out of the box. I'm going to go look now to check on this oil plug. Thanks for posted the photo. Very helpful. Has anyone figured out a part number or where we can purchase one?

thanks

On mine, I put a nail into the oil passageway and then epoxied the plug opening shut. I used the nail to keep the epoxy from going deep enough to block the passageway. I let the epoxy dry, removed the nail and went on about my business. Worked great.

Here's the answer (I think). No oil cap on the 025. Bar oil everywhere.

Thanks for the note. If you put epoxy over the nail, how'd you get the nail out?

I don't have the saw anymore, so I can't do a picture. I cleaned out the area where the plug should be with brake cleaner so the epoxy would stick to the plastic. I stuck the nail in the oil port outlet under the clutch cover. I probably sprayed it with WD-40 so it wouldn't stick to the epoxy. I worked some JB-Weld into the plug area making sure not to put in enough to stop up the oil outlet for the chain. I left it overnight for the JB-Weld to set up and then pulled out the nail. I really only used the nail to make sure I didn't do something stupid to block the oil outlet. I was afraid the JB might flow down the tube before it set up.
