Nuisance Bar Oil Leak

Like a Harley it needs to leave it's mark

Ever step in a pile of bar oil on a clean concrete floor? I almost went for a ride!

Having a similar leak problem with a CS2152. Thanks - this is helpful.

a clean concrete floor

What's that?

 

[Duane(Pa)]

Mine would literally drain the tank....

 

[Marshy]

What's that?

Another term for "walk path".

...on a clean concrete floor?

I checked that out on the debunk sites and various science question sites... they all said that there just ain't no such animal.

Common problem. Take the oil pump off, seal the inlet and outlet hose on either side. I also seal the large part of the hose that seals to the case. Be careful not to clog anything. I used black RTV. Everything has to be squeaky clean (oil free)

I'm going to have to give this a shot. The double sided foam tape didnt work. Its pissing oil. I enlarged the bar oil holes thinking if it had less resistance to get into the bar it would help but not the case. Unfortunately I probably wont have time to dive into it before I take it to MI for Buckin Stock. If I do it's going to be a long night.

@Marshy
I have found over time the rtv red seems to bite into clean rubber like rtv black does but seems to adhere better over time. I soaked everything in carb clean or brake clean on used oil lines. Sealed every connection including the case rubber ring on my Stihls behind the pump. Working the silicone on to the clean rubber and waiting till it starts to set. Independently coat every surface and go sparingly! Three years three saws no leaks.
Don't forget the oil line to the case area

I’ve had the issue w my 357. Took everything apart, cleaned very well and used good sealant. It works for a while. Eventually back to weeping. So I replaced the rubber lines. I’ve been using the saw a lot lately and it is completely leak free. I’m chalking it up as a consumable part. Owned the saw since new in ‘11 and that’s the first time I replaced them. I did make sure that bracket squeezes the square part tight. Used OEM parts too.

My 340’s both leaked, took them apart and sealed pump to hose and hose to case, no leaks in several years. Now just to do the 346 and I am done. My two series have never leaked.

Temperature changes create pressure in the oil tank and oil ooz out. Both stihl and husky sips. I dont say leak, but they sips a table spoon or so when stored for months.

Saw kings fix from 4 years ago. New line and sealant.

Um not any of my stihls and they sit in the hall way for 6 months over summer . I have never had a stihl leak now my 2 husky I called them Exxon valdez 1 and 2 (262xp 390xp) they leaked more than a drunken sailor ......

 

[Outback]

The problem there is Stihl's hold their oil so well they won't even leak on the chain when running...... ha ha.

Hm... I own a few low hour stihls, will sip a few drops a month from the adjust screw. My new 462 didn't run in yet and sip like 5 drops from 4 months of ownership. I drain the fuel but not oil, more than half full.

Yeah, that's not the case. I have other saws that will get run time right along side my 2159 and not leak any oil like the 2159 does. All the same environmental conditions too. Its definitely a rubber issue.

My biggest concern is that the oil isn't making it to the bar/chain.

Did you add sealant to the new lines during replacement?

I did not.

I am with Wolverine. Just had to re-visit this. Back at square one: new hoses and no goop. So far, so good, but only a few tanks... piss me off!
