I keep hearing people say Dirko is fuel resistant - it’s not..

[bwalker]

Hehe... I looked it up, the price gave me a really good and healthy laugh

It's not cheap.

You guys talk about airplanes, why exactly is not the car or motorcycle automotive stuff not the most common, likely and easy to get?
Quite sure there is lots of really good products around for those of us that don't need your chainsaws to get airborne, and that dont keep diamonds in our pockets.

There is. It’s called Motoseal, available at most all auto parts stores for about $8 per tube. That tube is good for about 100 gasket deletes

Yep, that's the one I use mostly. Available at our local Oreilly's.

I checked, and the Permatex Motoseal is not available on my side of the pond.
So I don't get the Motoseal and you don't get the MS241cm, I guess thats a fair trade.
I do get the bottle with a brush version in case I want my chainsaw to get airborne, but not the fast curing tube stuff.
I did find a Loctite on tube but it was 3 or 4 times the cost, I think I might go aeronautic.

I did find a Loctite on tube but it was 3 times the cost, I think I might go aeronautic with a brush.

Where are you going to be sealing with it ?

You send me a 241 and I’ll send you a tube or 3 of Motoseal.
Not certain if it has another name across the pond or not. And I don’t really know anything about it, other than it’s a case sealant made by Permatex

Well I use this kind of stuff here and there, when mounting the crank seals if the sockets is not perfect for example, or under the cylinder gasket towards the crankcase if I worry the crankcase split gasket pose a problem at the cylinder seat, or if I wanted to do a base gasket delete.
I probably won't be able to do a base gasket delete with the cylinder I have at hand now, but I would like to be able to if applicable.
Also I am to put together a 025 pretty soon that don't have a base gasket.

3 tubes seems pretty tempting, only one would be unfair.

Never had a problem with yamabond.. available at any Yamaha store.

But it is silicone based and only "oil and vater resistant" is it not, I've never had any problems with my gasket silicone either.
But I do like the idea of it being fuel resistant as well.

 

[a. palmer jr.]

I think maybe a lot of us are confusing "fuel resistant" with "fuel proof." Many of the sealers are fuel resistant up to a point, especially when they have dried. I think that might include Dirko, but after time and being constantly exposed to fuel, it will break down and leak.

 

[Chevboy0167]

^^^^^ Yup. And for the record, I was not advising anyone to buy and use the airplane tank sealant.... more of a joke at the sticker price!!! Plus it looks like it goes bad after opening and still has a shelf life when even still sealed. No thanks!

Motoseal claims it's fuel resistant. I'm sure it would work fine.

Given the work involved and the results if the gasket fails I would think that buying the best sealant money can buy is the prudent choice. It's not like you use a lot per gasket.

Well Yamabond or Hondabond will work there.

Yes, its a mix once, apply, and rivet up, tho it is structural too (going by memory), lots of work getting everything sorted, then one shot to put it all together, (Cleco city) and yes it can be messy, pain to clean up or remove from old tanks too.

I still have a tube of it somewhere, I think its more about using in a certain time frame to ensure its going to do the job, but if your not using it for aircraft, then use at your discresion, makes awesome thermostat housing gasket sealer hehe.

 

[Chevboy0167]

Yeppers. I bought into the Dirko bandwagon for a tube to seal up 2 Stihls at $25 for a big tube. But after looking deeper, it's just regular high temp silicone. Realized that after checking the website. Oh well.......

Motoseal does work fine, I have several saws that I've used it on years ago and still working fine..

I also believe it is not a silicone based product.
