Hey guys, I'm new to this site but it looks like a great one!
I have an 05 grizzly 660 that started to have a problem with coolant getting into the crankcase. I tore it down expecting to find a head gasket problem, but instead found a bad mechanical seal on the water pump. I replaced it and all the gaskets and put it all back together. Now I have a noise in the engine. I know the timing is right, I've checked the valve clearances, eliminated any rattles from heat shields etc, but I still can't find the noise. It really sounds like a valve clearance noise but they're set properly. Any ideas???
