Hi all
I recently changed oil and filter in the MH33D and now when I start it, it leaks oil from around the nut that holds the top onto the oil filter housing.  IS there suppose to be a rubber gasket under this nut?  
Any help would be appreciated.
Thanks, Glenn

Hope you have found the solution by now Glenn and stopped your oil leak, if not try a fibre or cork washer under the nut and do not 'over tighten' the nut in trying to seal it.
