Oil Leak!

[Turboryan]

With in the last month or so my 99' GS has started leaking oil.... Originally i thought it was coming from the oil filter cover or oil drain plug. Last weekend i changed the oil/filter/gaskets.  ITS still leaking...

I think i have the leak tracked down to the bottom of the right side crank case...

My question being, can i simply remove the crank case cover (drain oil first of course), remove old gasket, insert new gasket, then put the cover back on?  Or will it be more serious, such as having gears, parts, etc. falling out?

Any suggestions/tips to fix the oil leak are appreciated!

For what it costs, and for what is involved, I would replace the crank seal that sits behind the ignition advancer at the same time as the case gasket...if you dont you can bet in a fortnight it will start leaking and you will be doing the whole job again

Overall is it a difficult process?  I have done all the mantainance/repairs on the gs so far, so i would say i'm decent at wrenching. I'm just hesitant to open up the crank case...

Its not difficult at all....get stuck in, you will get a buzz when its done

It is really easy. The hardest part when I did it was to get the old gasket off. It was totally stuck to the cover and I had to scrape it off with a razor blade. It took forever. Besides that, it was a very easy operation and I've had no leaks since (from that gasket).

I need to do this too.  Just want to make sure if #12 here is the correct seal to replace.

Is there any easier way to remove the old gasket?  I thought using a razor blade was bad for the mating surface?

How about spraying to remover in a chemical safe dish (glass) and using an old toothbrush or small paint brush to apply it precisely on the gasket.   A plastic paint scraper would save you from gouging the mating surfaces.

If  you have any large caliber brass cartridge casings laying around, smash the bullet end  (of the EMPTY case) flat with a hammer....makes a pretty good scraper that won't scratch your covers.

Old Credit Cards (and the like) also work as a scraper (to an extent) and don't cut aluminum. The thread with pictures mentions gasket remover, and also mentions that it eats paint, but not too badly if you know it eats paint and clean up any that gets on paint as soon as it does.

I had a huge amount of trouble removing the gasket from my case cover when it started failing. I a can of one brand of gasket remover and half a can of another with little success. I finally resorted to a razor blade. It isn't that you can't use one, it is that you have to be super super careful not to mess up the mating surface. They don't have to be perfect, that's the whole point of the gasket, but they have to be pretty darn close. I also used a brass brush, which helped but wouldn't get the gasket all the way off in the places where it was super stuck. It took me a solid hour of scraping to get the old gasket off of the cover. Just take your time and be very careful.
