A few weeks ago I dropped my 570 in three feet of water and pulled dirty water into the intake and engine. After the bike was submerged, the engine immediately died, and was not turned over at any point until the engine was partially disassembled. Upon draining the oil it was very milky, so I obviosly pulled water into the crank case. I pulled the engine, pulled the cylinder head, and sure enough there was a small amount of water on top of the piston. The valves were in their closed position. There was no visible damage. Other than the water, everything looked very good. I compressed the valve springs and cleaned between the valves and the seats to make sure there was no dirt in the seal area. After thoroughly cleaning the head with the valves in place and lubricating everything with motor oil, I sprayed some WD-40 on top of the valves and let the head sit upright for a few days. I noticed after a day or more, that some of the WD-40 had leaked past the valve(s), but am not sure which - exhaust or intake. I have the new head gasket ready to install and everything has been cleaned out and is ready for re-assembly. My only concern, and question is: should the valves create a water-tight seal? I don't know how I would have caused any valve damage, but if I did, I'd prefer to address it now.
Any thoughts on this would be appreciated. The bike is a 2010 with maybe 1800 miles on it.
Thanks in advance,
