Permatex form a gasket sealant question?

[pablovent]

Hi;

In my local store sale two Permatex form a gasket sealant alternatives.......What is recommended for seal the case?

1.- Fast-drying, hard-setting sealant

2.- Slow-drying, non-hardening sealant

Thanks

[mark tucker]

neither but if you just have to use that crap... the non hardning.well either will do for a little while..... curlyt or 518 gellseal or halomar or...... something a little more modern that has bee updated and works and last.

Yep, if there's no other choice get the #2, but there's far better products that will prevent future problems available now.

ok, In my last engine rebuilts used Yamabond, but no longer sold in my city, I think anyway use Permatex 2 are better to RTV silicone?

Depends how it is applied. If you follow the directions on the tube, it won't work worth a hoot. Even putting a bead down and torquing the case isn't great. That said, I did use Permatex ultra copper on my case halves, but I had a different method of applying it that raygreenwood taught me. If you really want to know what that was all about I can put up some pictures if you want.

If you can get Permatex products, see if you can get their motoseal. It is made for motorcycles, etc, where precision metal to metal contact is present. It is very similar to the Yamabond you were using.

gell seal. = locktight 518. or OMC ( outboard motor corpration) case sealent. yamaha has thise own yamaha bond, I think we used #4 but not sure. it too can get messy and starts skining over as soon as it's out of the tube.
the locktight says messy untill it has no air as in between two peices and torqued down. so you can apply it and torque the case then wipe off the exsess withen the next year or so...., just dont do a partial torque then come back the next day to do the rest as it will of setup and your bearing clearances will be off!! and loose in the case and possiable case warpage! so make sure you want to finaly seal it up and do it.
silocone is good for exhaust and cylinder base&cylinder base shims. thats about all it should be used for on a vw.. never over apply any sealent as it will just squish out and in and then clog your oil pickup and kill your motor. Ive pulled motors appart that had the crank gallys packed with silycone , no way for oil to get to the bearings. so whatever sealer you choose to use use it sparingly.

Permatex #2, #3, 300, and "aviation sealant"
are all the same thing, but slightly thicker or thinner.

To seal the case split, use permatex 300 or permatex aviation, or hylomar blue.

Permatex rtv black ultra oil resistance?

[raygreenwood]

RTV is the wrong product to use to seal case halfs.

Yamabond/Hondabond etc.... are RTV's too aren't they? As Ray says RTV will work but it has to go on in a thin even coat, and don't let it harden fully before closing up the halves or it'll keep them from fully mating up.

One way I apply it to some things is with a squeegee with small notches filed in it (like a miniature linoleum adhesive spreader), that way it's a consistant thickness and has room to squish between the rows. A bit of coarse tooth hackswaw blade would work too if you weren't afraid of scratching things.

I like Gasgacinch for the case halves, for a leak proof seal.
