250-500cc Wr300 help

So I just picked up a rekluse from a fellow member and rushed home to put it in. I removed my clutch cover and to my surprise I found what looks like gray paint where my oil should be. Googled the situation and also asked a fellow member to see if this is normal. Coolant level was low so I'm thinking that's the cause. Member told me that it's a common issue for the water pump impeller seal to leak. What coolant it had in it is oil free. My question is while I have this apart should I replace anything else that's a common issue? I want the bike to be 110% when I take it out next.

Also if anyone had any gaskets for this situation I'd be more then happy to pick them up off you.
Looks like I would need :
Impeller seal
Impeller o ring
Impeller spacer
Engine case gasket
Clutch cover gasket


Thanks for the help in advance guys! Pics to come soon

That's water or coolant in the Oil, I had the same problem... Thought that the problem was the impeller seal but as it seems it was not, the little plastic 'L' from the crankcase breather hose was.. I sealed it well with some joint-former and now I have much less moisture in, still a little milky, I think I need to re-route that breather hose as I sometimes cross rivers above that plastic 'L' and moisture could get in.. I plan to route that hose over to the gas tank or something like that...

Regards.

WRs will do that if you cross peg deep water with a warm engine. the water rapidly cools the engine cases and the trans vent will suck creek water using the vent hose like a straw. You can reroute the vent hose to a higher location to avoid this. If you're not losing radiator fluid then change the oil and don't worry about it.

hey man,

Will do man! And thanks for all the help
