Nice video. Chainsaws don't leak, they mark their territory. 🙂

[@VintageEngineRepairs]

LOL! Thanks mate :)

[@steveriggenbach90]

Very good job of addressing the different problem areas. Unless there is a lot of chip build up I stop running the chain. Less residual. I also crack the cap then tighten.

[@VintageEngineRepairs]

Thanks Steve! Yep, keep it clean, crack the cap and you’re good to go :)

[@spiff1003]

That last one... That was clever. I have struggled with this on a couple of my saws, so maybe this is the reason. Just overpressure in the tank squeezing oil out. Cool deal. Thank you for that advice.

[@VintageEngineRepairs]

You’re welcome :)

[@tinkeringtaylor3053]

Excellent information video Tom well done 👏👏👍

[@VintageEngineRepairs]

Thanks Nev!!

[@fattoamanowoodwork3638]

Thank you for this, really appreciated

[@VintageEngineRepairs]

You’re welcome!

[@KensSmallEngineRepair]

Good vid Tom, I usually recommend draining the oil when not used for extended periods and cracking the cap as you said.

[@VintageEngineRepairs]

Spot on Kenny, me too. If it’s not going to be used for a month I’d suggest tipping it out, but less than that it’s a fiddly mess and not worth it.

[@TheLawnmowerLady]

Great tips Tom!

[@VintageEngineRepairs]

Thanks Stella :)

[@mkl5448]

Very good tips, interesting analysis but quite correct.

[@VintageEngineRepairs]

Thank you 👍

[@almclean4835]

Good info Tom

Thanks Al :)

Since 1984 and a new 024, I always thought that the bigger the puddle the better. Figured it was why saw cases didn't have holes in their bottoms.

[@VintageEngineRepairs]

Haha thanks for sharing

[@chazzmccloud36]

The old 028 Wood Boss that i inherited from my grandpa leaks like, well, like my grandpa probably did. I just figured the old Stihls marked their territory like old Harleys were known to do. My new 661 Magnum doesn't leak at all, yet. It goes through gas and oil like it's got holes in the tanks, but that just because it's such a thirsty beast. I find that if I lay the saws on their side, they don't leak nearly as much.

[@VintageEngineRepairs]

Thanks for sharing Chazz :)

[@Idahoprepper71]

The crankcase is constantly getting oil coming into it. Where does the excess oil not sticking to the parts go? What keeps it from building up inside?

[@VintageEngineRepairs]

Out the muffler! Either burnt or unburnt depending on tube and load

[@Lukedean-fl1lx]

My 036 leaked behind the oil pump , i just put a thin o ring to reseal the join to the oil hose , quik fix and hasn't leaked in years

[@VintageEngineRepairs]

Interesting! Glad it worked :)

[@rickthelian2215]

Bar Oils, using incorrect or a replacement oil that may be cheaper cause a leak if oil is to thin?😊

[@VintageEngineRepairs]

Hmm using a thinner oil shouldn’t cause it to leak no! You’ll pump more of it though :)

[@rickthelian2215]

@@VintageEngineRepairs thanks just a thought for those using other oils or worse used old oils.

[@mr1pearl]

And I thought mine was the only one that piddled like that 😆

[@VintageEngineRepairs]

Haha nope :)

[@patterdalezipsuzilil]

Do one on the dewalt dcmcs575n tentioner cog stripping problems 😂😂😂😂

[@VintageEngineRepairs]

Ah I haven’t heard about them, how frustrating!!

[@petefroud5308]

Good advice Tom . The caps a utter junk.

[@VintageEngineRepairs]

Thanks Pete, yes I much prefer the screw type for a few reasons!

[@chazzmccloud36]

Especially in cold weather, those bar oil caps are very frustrating!

[@aussiehardwood6196]

You do realise pro saws have a tank check valve dont U??

[@VintageEngineRepairs]

Yep, you do realise they’re only a 1 way valve don’t you?
