need some info

[buckle up]

i know this i gonna sound funny comming from me but here i go

trying to look up diffrent points in the engine of a 2000-2003 gsxr 750 where a seal can fail and let the oil mix with the coolant....

ok here is my problem....recently purchased a bike from a person who was running full water in the bike all yr...the used to be a racebike..i know this because of all the saftey wired bolts...

well needless to say the guy left full water in it over winter..

and i am trying to locate where the freezout plugs are in the engine if there are any..i never dealt with the water mixing with my oil

been trying to find a schematic on it but just cant

just wondering if any one knows about this

thank you in advance
