Have heard a few differnt methods when installing a new valve cover gasket ...
Spray gasket with wd-40 ?
Apply small amount of gasket sealant ???
Or nothing put gasket in dry with just a little gasket silicone around half moons ?
Which is best ?
 
In my manual it sais to apply a thin film of suzuki bond #1215 or equivalent to both sides of a new cam cover gasket ...
So which is it ? Some gasket silicone or none ?
 
no sealant to the gasket. You can put some on the under the half moons as they can tend to leak sometimes. You can spray the gasket with wd-40 in an attempt to have it come off the bike easier the never valve adjustment, it might even come off in one piece and be reused. Some people also use a form of grease, I think, don't quote me on that.
 
I've done a "Valve Adjustment" and "Oil Pan Replacement" and did not apply any products to either gasket and I have "Zero" leaks.

A surgical razor or equivalent tool and some patience and you'll get the remnants off any replaced gasket.

I use grease, or anti-sieze compound, and I can always use a gasket eight or ten times before they break, stick, or leak. Can do a lot more valve adjustments without breaking out the razor blade to scrape it off and when it does finally need to be replaced, it all comes off very easily.

Yeah, a dab of Yamabond, Suzuki bond, or three bond under the half moons if they leaked last time, but not where it wil stick to the paper gasket.

Seems like a no brainer to me. I would never use RTV or any silicone sealer anywhere like a Suzuki valve cover or anywhere on any engine that could possibly get it into the oil gallery. When a little string of RTV squeezes out inside the gasket it will never dissolve, when it finds it's way to the oil pump it will go through, either in one piece or several. This string will certainly be pumped around in there until it enters the first small oil passage it comes to, which it will block completely, and which will always be the one which lubricates the most expensive part of the engine.

edit, I tried using WD-Douche last time, it popped off fine a week later but I haven't had it on there a year cooking and then had it come off, so I don't really now.

What just a thin layer to each side of the gasket using some heavy duty wheel bearing grease ?
Spent all of last night approx 5 hrs carefully scraping and removing the old gasket , using gasket remover .. unfortunately for me the gasket stuck to the engine side and didnt come off with the cover ... and there was silicone all over it !!
Just checked the gasket and one hole in the gasket isnt where its sapose to be !!!
Every there hole lines up perfect ... wtf :mad:
 
If this is the gs650, there are two cam cover gaskets available depending on engine # ; later models had extra bolt hole for extra cover bolt.
 
New gasket .... wtf no its not oem that was going to take 3 weeks to get here ..
Do you think if I carefully trim where the one bolt goes through off the edge of the gasket it will hold until the new gasket comes in ?
 
Damn you know your stuff Tom !! Lol im guessing this is exactly the case ...
New gasket doesnt have ahole where one ofthebolts go through , mind you gasket material isnt covering hole , the hole I am concerned about is the one where idhave to trim a little gasket material !! Ordering oem today , so my question is do you think this gasket will hold for3 weeks ??
 
Since all the other holes line up, I'd use gasket as is- and skip that cover bolt for now. if you grease it, should come off with no damage when you get correct gasket.
Beware tach drive when you put cover back on- make sure gears mesh nicely before bolting down.

Edit; mine has no extra bolt and no sign of leakage
 
If you take a quick look at the pic Tom one hole in the gasket isnt where it should be ...thats the area im concerned about ...????
 
Skip that cover bolt ? Realy ? Not just trim a smidge off the gasket so the bolt can be put in ?
 
Grease it, trim it, ride it. You have the right one coming... It looks like you have 2 to trim. One by the cam chain and the other... Then again it could be my eyes...

I brush on a very thin layer of light grease on the engine side metal surface, position the gasket on the engine, then brush a very thin layer of grease on the exposed gasket surface.

Works great, you can take the cover off in one piece numerous times for valve adjustments & the like.

Under the half moons, I clean the metal very well & make sure there's no gouges or rasied metal, lightly clean up the metal with 800 grit paper, then apply a thin layer of black Permatex gasket goop to the metal only. Push in the half-moons & you're good to go.

Also, lots of members here put the half-moons in backwards, so the lip is on the inside of the cam cavity - keeps them from popping out, as well as minimizing any cam end float.

BTW - don't know if you are re-using the old half-moons or getting new ones. Z1 Enterprises sells a set of aftermarket half-moons that work quite nicely for a lot less than OEM ones. I've used several sets & have never had an issue.

I agree with you Tom . As for the shop that sold me the gasket , he wont take the gasket back , cuzz it was removed from the ziplock bag it was in !! Dick ... and hes the one who ordered it for me !!
 
Yeah the old half moons look to be in fine shape .so I eill re use them !! Dont want to rebuild the bike , just want to keep it running while I get my 78 gs 1000 running good ... plan on selling this bike soon !!
 
Thanks all for your tips tricks and support !! Leaving work now , heading home to get this bike put pack together ....
