Hey guys. I'm rebuilding an '06 450 engine for my neighbor. The front/exhaust side cam chain guide/slipper has chunked out pretty good. I found a good amount of the rubber sitting in the flywheel actually. I was thinking about pouring some kerosene down into the bottom end to flush out any other pieces down there. I have the entire top end, flywheel, and clutch assy. off right now, so it I have clear passages into the case. My concern is floating rubber chunks or debris up into areas they may get caught in and do damage. Possibly lodging in a bearing or oil passage. I'm not going to fill the thing, just enough to slosh around. I guess I just want some reassurance. Btw, my advice to the owner was to split the cases and thoroughly clean, but he doesn't want the extra labor. Thanks.
