there have been many simalar threads, but I am going to step out and ask. what do you use for sealant on side cover gaskets and valve cover gaskets of the cardboard variety.
thanks pat
 
Take that tube of sealant and deposit it directly in the trash, being careful to make sure it does not EVER go within 20 feet of your GS.

Seriously.

Install gaskets dry or with a light coat of oil.

I agree, avoid using sealant. It can clog/block oil passages.
A light coat of grease or oil is ideal to prevent gaskets baking onto the ali surfaces.
 
You know, as a LICENSED motorcycle mechanic & ex-Suzuki dealer mechanic, I am really amused at some of the STUPID things I see on this sight posted by people that apparently have NO idea what they are talking about. Just because some of you don't know how little sealer is enough on these bikes doesn't mean you tell everyone to just throw their's away! If you will READ your Suzuki factory manuals you will see there are places that CALL for sealer of some kind. There is a REASON!! Learn how to use your chemicals CORRECTLY & you will be happier & trouble FREE! By the way, Gasgacinch the paper gasket to the valve cover & LIGHTLY grease the other side where it contacts the head & you will be able to use that gasket for a LONG time. But, you still have to put sealer on the half moons where they go into the head. I use Threebond 1207B. Ray.
 
Sealant

Sealant

I've always used a little sealant successfully......but I use very, very little of it.:|
 
NO SEALANT light coat of oil

Disagree (sorry Lynn)

Yahtzee!

If there was a "beating a dead horse" emoticon available, I would use it here.
 
I don't recall exactly on all Suzuki gaskets but many OEM factory gaskets have a light coat of sealer on them already - activated when baking. These gaskets should be installed dry to get the best seal. If you grease them the sealer will not work.

I choose not to use sealants for most applications. That doesnt make me stupid OR uninformed.

On the specific gaskets mentioned in the original post, no sealer is required.

I will be the first to admit that throwing your sealer in the trash is an oversimplification, but it is a useful one in this case. Perhaps I'm making an assumption, but if the original poster had a manual, he would have seen for himself that there are certain specific uses for small amounts of sealer.

Maybe I'm a little harsh, but there's a lovely GS850 engine sitting under my workbench with a seized crank caused by the PO's slovenly habits with sealing goop.

Of course not Earl! Certainly there are many other reasons for that!

:razz:
 
None is needed. If you're having trouble keeping it postioned while fitting the cover, a small amount of grease will work as a temp "adhesive".

E.

what kind of sealant is recommended for the clutch cover???
 
Hylomar is what I've used for years.

No leaks, no silicone. It is a chemical seal, not "goop." It helps in the positioning, but it also allows you to re-use your gaskets the next time you need to remove the cover.

Hylomar is great when you have dinged up metal surfaces, and it won't clog things up inside the engine.

For those who haven't encountered this stuff, it's a bright blue, extremely thick, very sticky goo that never hardens, never liquifies, and isn't affected by heat, oil, or gas.

If you use it wisely, Hylomar is quite useful when dealing with elderly, less than perfect machinery.

no sealant is recommended for the clutch cover, If you need some thing to hold it in place for installation, a little grease or a couple of dabs of 3m super weatherstrip adhesive works well. If you use adhesive, stick the gasket to the cover, so it is easier to clean off the next time.
Generally, use gaskets or sealant, not both at the same time.
 
i dunno but...

i dunno but...

loctite #515 is a purple very thick and similarly sticky substance which is said not to harden be affected by solvency of oil, gas, deterioration caused by heat, etc, etc. maybe the same stuff as hylomar in a different package. maybe easier to find.

i know for a fact that john deere calls for loctite #515 on the rear differentials on the new series of construction dozers. loctite #515 and only loctite #515-- no gasket. just beveled flange faces like a pipe union and the chemecal sealant.

my source is my old man's-- a field mechanic for Yellowhouse in Amarillo, Tx.

Thanks for the info -- that does indeed sound very similar to Hylomar (which is a Permatex product, I think).

And purple goo is way cooler than blue.
