Weeping oil from cam rubbers

[Guest]

My 83 Gs750e has 8500 miles on it, it sat in some guys garage for 17 years. The seals dried out and some oil weeps out of the rubber camshaft cover on the rear left. I've ordered new ones. Will I need to pull the valve cover to replace them?

Very difficult to lift the cover and sneak some pliers in, without disturbing a gasket which has been sitting confortably for almost two decades. More so, what better occasion to check valve clearances...

Agreed. Valve clearance and valve cover gasket are on the list. Also engine side cover gaskets probably need changing. I haven't seen these rubber plugs yet and so wasnt sure how they were installed. That helps me a lot! Thanks!

I have spent two hours scraping those valve cover gaskets off. Sometimes it comes off perfectly, other times it goes south.

I have been very happy with the permatex grey (high torque) rtv for the plugs, no more weeping, even with old plugs. Also doesn't stick out as bad against natural aluminum.

Yeah, two hours minimum for a petrified gasket. I just did mine last weekend. Carbide gasket scraping tools work great ($15 at O'Reilly's) , as long as you're careful to avoid gouging the surface.

Got around to pulling mine a couple days ago. Has an o ring! Easy street.

Those end plugs, jeez. I replaced on both my bikes recently, meticulously cleaned the surfaces, used a thin layer of Yamabond, new OEM rubbers, and boom, out they came, spewing oil on. Did the job over 2x to try to fix and no joy. I have no obstructions in my breathers or any other factor that would cause high internal pressure, they just wouldn't stay put. I put them in with the lip inwards and have no problems whatsoever. There seems to be plenty of clearance, will find out if any chafing at next valve cover removal, for now I'm happy to not have leaks.

As you can see from my first post, this is my first time messing with them, they seem like one of those things that would have been nice to invite a mechanic to sit in on the day the engineers were designing that particular part, but its great we can still buy new ones!

Isn't joint bonding goo made for metal on metal?
This is superb

I've never had a leak after using it. Nor seepage. Soluble in alcohol.

It's not weeping oil. It's sweating horsepower.

I've fitted mine inside out since one came adrift 100 miles from home and left me stranded. It's a serious design flaw, that could have been totally prevented by making the inserts double-lipped.

Yes so call alibabs and have some made

[oldGSfan]

Heck I even have that on hand, and yeah it'll stick to everything. I use it very sparingly, a little dab'll do ya. Reversing worked a treat so I'm OK with that. I think I read up to use Yamabond or equivalent but it wasn't right for the job. I wonder what was used by Suzuki new.

Personally I try not to use rtv on those rubber plugs, I use a small amount of blue hylomar smeared on the rubbers let it flash off for 10 minutes before fitting never had a problem with them. Don't try to fit them before you let it flash off as they can slide out when fitting the cam cover I suspect that also happens with rtv.
As for the camcover gasket smear high temperature grease on the camcover and cylinder head mating face before fitting the gasket and you will never have a problem when you next take off the camcover.
