Engine Refurb
The back of the head on the M50 engine has an outlet for the cabin heater. I'm not going to be having one so needed to blank it off. I made a template with a piece of paper and cut out a rough shape from 3mm aluminium. A bit of filing, sanding, polishing and two 5mm holes with some cut down M5 screws finished the job. I ran some RTV silicone underneath in lieu of a gasket and as the cooling system is not under high pressure, this should be fine
[EDIT] I've since put the outlet back on and plumbed it in as I was worried about not getting the correct coolant flow near the back of the head. May revert back again at some point though
