81 GS850G leaking again

I have had the worst luck when it comes to my GS850G, and trying to keep it from leaking. I have replaced the base gasket 3 times and now one of the oval shaped o-rings has failed and oil is pushing out through the gasket. No this o-ring was not OEM. I am planning on tearing the motor apart again. Obviously this will involve replacing the head gasket, base gasket, o-rings for the cam chain tunnel and the head studs where the oil travels.

So here is my question; when I replace the base gasket, does it go on dry, or should I use Copper Coat or Gasgacinch type compounds? Also I have a multilayer head gasket with very few miles. Could I possibly use the Copper Coat type stuff and re-seal it?

Just to let you know I put a straight edge to the base and to the cylinders and there was no warping at all. I am at the end of my rope and need all the best input I can get. PLEASE, PLEASE HELP!

Thanks,
Scott
 
Sorry to hear the crappy imitation base o-rings collected another victim.

This time, use OEM gaskets and o-rings and you'll be fine. They cost a little bit more, but they're worth every penny.

The head gasket will not be reusable -- buy a new one.

Don't use sealer on the base gasket or the head gasket. (use a VERY thin layer of Hylomar -- NOT RTV silicone -- on any gouges or damaged areas).

Gaskets all go on dry. The exception is the clutch cover, stator, and valve cover gaskets -- a layer of grease or oil will make these much easier to remove without tearing later on.
 
I've seen Hylomar in Harbor Freight, believe it or not, but you should be able to dig it up at any decent auto parts store or order it online. If you have any racing-oriented shoppes nearby (car, snowmobile, motorcycle, etc.) they should be able to point you in the right direction or sell you some.

Purely for edumacational purposes... Why the Hylomar instead of RTV? Is it because Hylomar universal never sets, or is it a temperature thing, or what?

RTV likes to make little crumblies that break off inside the engine and plug important things (DAMHIK :mad:). It also sets up firm, and between the time it takes to put the block on and torque the head bolts, it will set up permanently and then create problems with the gasket seal.

Hylomar stays flexible forever and stays in place at high temperatures -- it's basically a super-viscous liquid that's not affected much by chemicals and temperature, and bits of it in the engine won't break off and hurt anything.

It's great for dinged-up cases because it helps seal imperfect surfaces without interfering at all with the function of the gaskets.
 
Is there a difference between Hylomar and Hylomar-Permatex? I did a Google search for Hylomar and got results for both.

As much as I like my GS, I won't go through that much trouble or expense. I'll stick a for sale sign on it first.
 
It doesn't cost that much to do. If you have it apart just do it.
I just had the head and cylinder milled, pitted head welded and cleaned, four valves recut and the cylinder honed for $200.
