hey all I'm new to the forum and thought I could er some help. I'm restoring a 87 650sx.. engine is complete and needed a carb, motor mounts and cradle, however I noticed that whoever had it before me broke the nipple off flush with the hose that runs from the exhaust Chanel to the back of the engine compartment.. I believe that this hose line feeds into the pump to expel water coming out of the head after cooling... seeing that it's broke off flush.. what are my options? Hole saw and cut around it to re attached and then seal it up with silicone or some sealer?
