I have an oil leak where the crankcase cover meets the rest of the engine (forgive my blunt terms due to lack of knowledge) I unattached it and cleaned it up good, even got a new oil seal for the gear change rod, just in case that was it. I put it back together and now it leaks again. Is there any product that can be used to patch it up, such as a sealent? seeing as there is no gasket that goes there Id like to know if there are other alternatives
thanks
Are you POSITIVE that the leak is coming from there? It's very common for chain lube to pile up under the front sprocket and to come out there, making it appear that there is a leak, when it's really excess chain lube.
Clean it really well, put some baby powder on the outside of the cover, then take a ride. The powder will let you see the path of any oil. Because of airflow around the engine, leaks tend to APPEAR somewhere and originate somewhere else. It's hard to find them sometimes.
Im 99% positive its where the crankcase cover goes. I ran the motor without the cover on, and it didn't leak from anywhere though. I have feeling its where the gear shifting fork goes though, thats the only place where oil seems to be coming out of, if i pull it out oil drips out, and it matches up where it leaks out under the bike, wat could i do?

Take the cover off and clean the heck out of that space. If it is anything like mine, it is completely full of all kinds of nasty crud that will take you forever to clean out. Once you've done that, go for a decent ride to get the bike nice and warmed up then pop the cover again and you should be able to see the source of the leak.
You already replaced the seal on the shifter. If it's chain lube it won't leave a puddle on the pavement. If it does, it's engine oil.
On my bike it's chain lube. Not a problem.. unless you like to ride wearing white shoes!
I blew the gasket on the shifter side. It eventually got bad enough that my whole boot would be covered in oil after 10 miles on the freeway.
It was pretty easy for me to tell it was oil and that the gasket was bad after I cleaned everything up. I found that the oil was coming from the front. Replacing that gasket was cheap, but a huge pain in my arm. Gasket remover (spray) will remove EVERYTHING from metal, including paint. So, I scraped as much as I could, sprayed a rag, and wiped the rag on the gasket, repeat, repeat, repeat.
If you ARE leaking oil and it IS your gasket, be very, very careful when you tighten all those little bolts. They need something little like 6 ft lbs. DON'T BREAK THEM!
I figured it out. I'm a hundred percent sure its the hole the gear shifting fork goes in. I haven't got a time to take a pic yet, but its http://www.bikebandit.com/suzuki-motorcycle-gs500ep-1993/o/m6053 (http://www.bikebandit.com/suzuki-motorcycle-gs500ep-1993/o/m6053) its number 4 under gear shifting (if anyone takes the time to look :)) ik thats the source now for sure, but have no clue how to go about stopping it. sometimes when i replace the cranckcase cover Ill run it to see if it leaks and it dosent and ill even ride with no leaking, but then when i turn it on again it will leak again, it is really weird.
Don't you just need to replace the oil seal? Part 29 in this diagram:

i replaced that already but that wasn't it. the oil is leaking out of part 3, where part 4 goes in. I just have no clue how to stop it.
I have never been inside my GS tranny, but if I'm not mistaken those are the shifter forks -- you aren't seeing those unless the tranny is open. That's all INSIDE the oil bath. No possibility of a "leak" to the outside there.

Yeah, that's what I was thinking. Is he thinking of the clutch lifter? Perhaps he needs the oil seal labeled 21 in this diagram:

Im seeing the fork that attaches to the crankcase cover, thats the only part I have open (don't know if that helps...) I'm going to try to put pics up
heres the pics of the rod and of a broken part (there was a same sized washer with it) that i found in the trash inside the crankcase)

im really sorry bout the quality guys
now that i put pics up noone answers? :icon_confused: anyone?
That's your clutch pushrod. The oil seal is part #21 in the diagram fred posted. Fred is right again!

I think mine is leaking too - what's involved changing that little seal ? special seal puller ?
I have done one but it was years ago and cant remember exactly how I did it, dont remember it being difficult or having any problems though.
Drain the oil, the rod pulls out, sprocket comes off, retaining plate comes off, lever the old one out with a seal-remover (Like this one)....

Lube the new seal and drift it in nice and square with a socket.
and that seal connects to the cranckcase cover right?
