Bar oil case leak?

[davidwyby]

Keep noticing this, haven’t messed with it yet. Maybe oil is getting over there from the clutch area…? But I think it’s the case gasket. I’m not about to split the cases just for that, any bandaid ideas?

Looks like the case is cracked? JB weld? I would get a different case half and repair it correctly. If that's J-Red a Husky half will work, painted Red.

Looks like the case gasket is compromised under the muffler. There's not much of a bandaid fix for that. I've seen guys try to patch those with JB Weld and that's usually temporary. If you decide to go that route, I've had better luck with the JB Marine Weld for oil resistance.

Have also seen gasket fail and bar oil gets into crank area. Are case screws loose?

had a tank leak like that on a steel 201.
i emptied the tank,, super cleaned the tank in and out,, ethered it .
then forced permatex ultragrey in the void until i saw it coming inside
let dry for a few days,, been over 2 yrs and so far so good.
Cant hurt to try

I tried chasing a seam crack on a MS 391 (found out later that the guy dropped a tree on the saw) with JB weld. Didn't work, the thing kept leaking, from where I don't know. Spent $30 and got a used case on e-Bay.

Might be worth it to split the case and replace the bearings while you are at it, give it a good once over while all apart.

Just swap over to using grease instead of oil!

Could degrease it, cover with Motoseal and pull a vacuum on the oil line. Can’t hurt for a quick fix.

Worked on JJ’s 066 crank seals

How about taking the time and repairing it correctly, unless the saw is not worth repairing.

You got a spare few hours you could send me? ;-) maybe this summer, indoor season. I think I did check the front case bolts.

It's a 2175 kevin ported for someone else a few years ago I got third hand, not a lot of use on it, runs good, it's sawing season, and holidays, etc.

If it was an old stock saw I'd send it off to rebuild and port...

 

[Wilhelm]

How much is it leaking?

Just run it as is and dump the oil when storing the saw?

It's basically what I do with my pissy Dolmar's, just a couple of the large frame ones actually.

 

[Wilhelm]

Reroute the oil and fuel lines?
That way You won't have no more oil leak!

It still runs out of gas before the oil so that's good. It'll probably wait til summer

He could just run it with the oil tank dry, carry a bucket of oil with him, and dip the bar every other cut.

Could put the oil in this and then run the line to the oil pump problem solved. And your head will be protected from falling objects too...

Plastic tank I just fixed on a 250, cleaned well with rubbing alcohol and plastic welded it with zip ties and a cheap harbor freight soldering iron style plastic welder that was 30$

I did pretty much the same on an Stihl 026 only used, high heat silicone and it worked. Used the saw years and sold it. I did loosen the case screws prior to cleaning and then tightened them back after some drying time.

Every cut. Dry hard dusty wood you know. You come carry the bucket.

If You can clean the tanks inner surface and somewhat well reach the leaky spot from the inside - stick a bandaid on it, something oil resistant like a chainsaw decal.

I bet 3M has something in their offerings that would work.

Super Glue/Bond it?
The liquid one really seeps into crevices and cracks.

@davidwyby
Did you check to see if the case fasteners are tight, especially up front there?
