Whilst this is obviously a fundamentally good idea, I can’t see the sense in taking the groove across the bridge at the rear which is not a leak path. Would it not make more sense to continue in a smooth route around the oil containing chambers without any need for joints?
Some viewers have emailed asking who did the machining of the groove. Sadly, the gentleman that did it has now retired so there's no way he can do any more cam covers. The only solution is to find a suitable machine shop that has the necessary machines and a skilled operator I'm afraid…
If you're dealing with an earlier style of engine cover it's a good idea to "flat off" the tops of the stud holes on the top exterior of the engine cover to enable the Dowty Washers to seal to a nice clean flat surface. This wasn't required on the Elan Sprint example shown in the video as it already has nice flat surfaces which come as standard on these later engine covers.
A top tip is that when applying the Blue Hylomar sparingly, only apply the Blue Hylomar onto the rubber seal itself and onto the outside of the seal only so as to avoid excess Blue Hylomar being squeezed into the cylinder head interior, as it will begin to be loosened off and might enter into the oil system which is really what you don't want to happen!

Brilliant, New ones should come like this..
