No more Permatex Motoseal for me.

[Zombiechopper]

Indian Head, you putthies....

idot!!

permatex aviation gasket maker is the real deal. We used to call it the 'black ####'. Got some on my finger once. Now I just say it's an ugly mole cuz it's easier to explain

Permatex Ultra-Grey. I have modded a few saws.

This was copied right off the instructions for Ultra Grey:
NOTE: Not recommended for use on head gaskets or parts in contact with gasoline.


Threebond 1194 for me.

Not sayin its the best ,but this is what I use.

that's the stuff I was talking about. Smells yummy.

I use that Aviation Forma Gasket alot on big equipment, but it's just too darn nasty for me on saws! I only like using it in places that I can clean up with a polishing disc on a 90* die grinder! It will work though.

 

[wkeev]

Dirko . IMHO

 

[dflippin08]

Use Dirko

 

[PogoInTheWoods]

Dirko.

 

[Miles86]

I like Hylomar Universal (racing formula), or Loctite or Permatex anaerobic gasket maker, especially for machined flanges with precise uniform gap.

 

[Vintage Engine Repairs]

Dirko

Could running a high ethanol fuel have made any difference?

 

[sean donato]

Nope, when we raced unlimited offshore dad used motoseal on that, alcohol, nitromethane. Never was an issue.

 

[farmguywithasaw]

Dirko or pactan equivalent you get from stihl. Or loctight 515 I think would work as well

 

[Jasent]

With moto seal you do not want it to skin up before assembly. Dosent stick as well. Apply and assemble right away. It cures up fast. 5 min is too long ime

515 or 510 work just fine.

MotoSeal Ultra Grey certainly has its place and can be used many ways. Applied to both surfaces and smoothed to set for 1 minute prior to assembly it dries in 20 minutes. Good stuff, but needs to be used correctly. Solvent based. I rely on it it for certain applications -- McCulloch 10 series fuel tank seams immediately come to mind. LOL.

Many people think DirkoHT Red is a Stihl product and reject it out of hand as Stihl haters. It is actually made by another European company called Elring and has been used in the Euro auto industry for years. Exceptionally suited to high temp fuel resistant saw applications. Much more forgiving than MotoSeal during application and disassembly. Superior to most of the other similar products in my opinion. Silicon based. My preference.

Three Bond 1184 is essentially the main (insert whatever **** Bond here) product of this family of sealant/gasket makers. Fine, high quality product used by many. Also solvent based. It's my Dirko backup for base gasket deletes and sealing clamshells. Application can be a little sloppy, but the end result is a dependable seal.

Loctite 515 is an aerobic sealer and needs to be used the right way for the right application. Surface prep and component conditions often determine the success of the application as it basically remains a liquid until the absence of air -- which then allows it to 'set' as a semi-flexible sealant. May or may not be a long term solution depending on any number of variables. I've read of disappointing results with 515. No reason to chance failure (unless experienced using it or it's all you have) when the other products are readily available and proven to be dependable solutions..., at least IMHO.

And finally, bear in mind Permatex makes several 'MotoSeal' products. Ultra Grey 29132 is the one to use. Using a different version may not yield the desired results for typical chainsaw applications.

My response is from personal experience. No issues. Plenty of my ported saws out there running just fine.

 

[PogoInTheWoods]

Works for you. Great. Didn't say it doesn't. Just wouldn't be my first choice given equal availability of the other products.

 

[Yotaismygame]

"didn't say it doesn't" oooookay sure you didn't.

Real world experience > speculation. Sorry.

 

[PogoInTheWoods]

Apology accepted. LOL
