Why Is Dave's Stihl Chainsaw Leaking So Much Bar Oil?

[@donyboy73]

Fix 90% Of Chainsaw Bar Oil Leaks With This Simple Repair! kzbin.info/www/bejne/qJ2QaoOkjbJ3gZY

[@thinkingimpaired5663]

Thanks for the suggestion because my 193T leaks so much oil that I only fill chain lube just before I use my saw. I remember seeing your oil line replacement video and have been avoiding doing that repair. I'm hoping the o ring is the defect. I thought my leaks could possibly be from the high temperatures where I store my chainsaws.

[@stuffbywoody5497]

Hi Don, I just did a bit of a binge watch/catch up of some of your videos. Always good. I'm in Australia 🇦🇺 and enjoy your videos quite a bit. I have had a stihl ms170 for a few years now and I'm wondering if there's any upgrades I could do to it to make it a better saw? I prefer the old style oil and fuel caps that are on it, so don't want to change that. But any other suggestions would be appreciated. Thanks Don.

Hello, I have a Stihl MS362 and I do not see the Screw Adjustment Limiting Pin, but I found it on my MS661 and made the mod to increase the movement farther to the right of the screw. I could not find the same Limit Pin on the Oil Adjustment Screw on my MS362. Does the MS362 have an Oil Limit Pin on it? The whole around the adjustment screw on the MS362 is very small, the same size as the head of the screw. I do not see the Limit Pin. Do you know how I can access the pin? What do I have to take apart to access it? If there is no Limit Pin, do you know the part number for a high volume/high output Oil Assembly for my MS362?

[@johndimech8945]

Another informative video. At 5:34 Dave put the oil cap on with the saw in the upright position which tells me that the oil level was below the point that his oil would leak if the cap were the problem. I have a 180MS which leaked from day one. I took it back to the dealer and they told me that all saws leaked some oil. I challenge that response as I have had saws for 30 plus years that never leaked and a Makita that leaked from a worn oilline. I thought, since I had a 2 year warranty I wound see if the the problem persist over time. My cap is a screw on cap that you finish tightening with the slotted screw driver end of he spark plug wrench. I found the screw driver end to be a sloppy fit. So, one day I ground the tip down to a thickness from 1/16" to about 1/8" thickness. The tip then fit into the cap snug and I was able to tighten the cap without chewing up the slot in the cap. That problem was solved and I realized that I had inadvertently stopped the oil leak as I was able to tighten the cap properly with out fear of messing up the cap tightening slot. It has never leaked since. That was 4 years ago.

Dony awesome videos!! I have a new stihl farm boss with 2hrs work time after sitting in the case for more than a week there was quite a bit of bar oil. it's not coming from the cap, I took the bar off & it seems to be coming from the oil outlet area. Any help would be appreciated thanks Rob....

The last tip about revving the chainsaw without actually cutting anything was my problem. Bought my first chainsaw and tested it without cutting anything, ran inside with it to only notice that it was dripping oil like crazy. My chainsaw doens't have an oil adjuster knob so i was allready panicking my chainsaw came with a defect out of the box. After some time the dripping stopped so it was just all that oil from the revving dripping out. Thanks!

[@aguertin3846]

Maybe the oil was to light for the outside temp. Maybe the oil dispenser is not well ajusted if this model have this option. I own 2 Echo chainsaws and it is the case for both of them. Could be a good idea to unmount the clutch and bar area and clean them before diagnose the problem?

I've also got the MS 260.... It leaks oil like a barrel full of holes.... 'Steve' has done a vid pointing out that right next to the muffler is an oil hole which needs to be blocked. And this is exactly where mine seems to be pouring out. The muffler needs to be removed to see the spot and since I've already got an exhaust gasket on order, I'll wait till then before I take another look here..... Stihl part No. for the set screw to block the leak is 0000 953 1001. Maybe check his video out too as what he has pointed out might just finally be a 'light bulb' moment for me after so many years of working with a motorized sump. Great machine otherwise.

Bar oil always leaks after use if not cutting wood. If after cutting wood, the excess oil leak is apparent, you must investigate a problem.

[@KM-os4be]

Seems like all chainsaws leak a little bar oil. Some things I have noticed over the years is my Echo saws leak less bar oil than my Stihls. I've found that after running the chainsaws before puting away I crack open the oil cap than tighten it back up and let sit in the oil pan a few hours to let the residual oil drain off around the bar/sprocket area.
