The final word in half moon sealant

[chiphead]

As the title states, I'm looking for the final word in an aftermarket sealant I can use on the cam end half moon plugs. The PO grooved the bottom sealing surface on the head of one of the half moon plugs seats. I'd be riding if it wasn't for that. Thanks.

I'd use some Yamabond, or the like. Works good on the rest of the seals. I use it on the cupped portion, and use regular gasket goo on the top where it seals to the cover.

I also use sealer on the curved section, but don't put anything on the flat side.

Threebond 1211. Or yamabond, hondabond, suzibond which are the all pretty much the same thing.

I just fixed up mine with new moons, a realgasket and a little Threebond. No more leaks!

My 2 cents

The official Suzuki Bible says to put a little 'goop' on both sides of the gasket so that's what I do..(It comes off easier that way, too.)

Do whatever you want and if it doesn't leak oil....you've done good!\\/

What is the "official Suzuki Bible"? Factory service manual? And just wondering but what kind of "goop" do you use? My 550 gasket, installed dry, weeps a little. Would have used some sealer but those darn gaskets are pretty expensive.

Manual

I was referring to the factory Suzuki manual. I use the grey silicone 'make a gasket' stuff and put it on uniformly....but very, very thin. It seems to work well and I've noticed that the gaskets don't stick when I remove them. The manual says "A thin film of Suzuki Bond No. 12078 on both sides of the gasket will ensure an oil tight seal". (I don't know what that stuff is or if it's even still available.)

I used a very thin bead of Locktite 518 gasket maker on every surface of the cam cover, half moons, and the top of the head. No leaks anywhere.

[Planecrazy]

I've always found that a light bead of "Form-A-Gasket" works well - I usually use the high temperature version (which is generally a light reddish color).

Thanks for the replies. Looks like any semi drying hi temp gasket goop will work.

I would like to add that many people recomend yamabond or the honda suzi kawi equivilant.

one problem, there are differant versions of yamabond for differant applications.
yamabond 4 was the item of choice but I have heard it is no longer available.
hondabond 4 is still available and is the same stuff.

permatex ultra grey is also the same stuff. a firm setting silicone

you can also get some realy great stuff from Ford (motorcraft) that they use to assemble engines and differentials with. we have many Fords with gas engines in our fleet (thousands) and they don't leak.

one of our customers had four E-350 based box trucks with the 5.4 gas V-8 and all four had between 175-and 190 thousand miles on them when we retired them and none of them had the slightest hint of a oil leak any place.

I'm pretty sure I have a tube of yamabond 4. It's still soft in the tube. Think it is still good after 20 some odd years?

Probably

If it's soft, pliable and doesn't appear to be separated, I'd use it. Lot's of things stay good for more than 20 years (thank goodness!:-D)
