Yes, but I'd like to use the original part to do it. I had a few leaks last year and not sure the oiler was the issue. Just thought I'd replace it anyway over the winter to eliminate a possible leak. Wondering if the oiler looks good enough to reinstall or best to just plug it with the one I made. If I do use the oiler should I replace the rubber ring? Do the chain oiler's effectively stop the oil from leaking out when turned off or does it still leak a bit anyway? If its going to be a nuisance I'll plug it with the spark plug.
