OutdoorKing Repair Forum Forums Restoring, Customising and Modifying Tech Talk how do I fix my mower

Thanks for clearing that up, charmaine. Now, you can replace both those gaskets, but the crankcase cover one in particular is a fair amount of work. Also, you may not be able to get spare parts from Rover, and we have reason to suspect that those parts may not be top quality anyway. Furthermore we can't be sure at this point that Honda parts will fit. I've already referred to the way I would proceed with this. I would remove the cylinder head, clean up the joint faces, take the cylinder head to a Honda dealer to check whether a Honda GXV160 head gasket was a perfect fit, and if it did fit, I'd use one of those. I wouldn't actually reinstall the cylinder head at that point though. I'd remove the engine from the mower, then unbolt the crankcase cover from underneath the engine, clean up the joint faces, and take the cover to the Honda dealer to see if the GXV160 crankcase cover gasket would fit. If it did fit, I would reassemble the engine with both Honda gaskets and refit it to the mower.

If you decide to make the repairs, I can help you along the way with details from the Honda service manual for the GXV160. I don't think there are any service manuals for chonda engines, including the Rover one, especially in English rather than Chinese, but I could be wrong about that.
