Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Quick Question: Oil tank cap gasket

Bu66er. I now have rubber floating around the engine. They splinter when they go.

Is taking the optimistic decision that if you don't do more than about 1500 miles a year (between oil changes) then you don't need to look in the tank between services a safer strategy than I had thought?

No... its all my fault for over tightening.
hopefully it will be ok with an oil and filter change. I think I got 99.9% of it. My new bicycle tyre gasket is better becuase it produces less of a pinch.

Charles, the oil tank cap is 'Malvern' quality, had the same issue... ...Easyest fix: go to a rubber shop and ask for oil resistend rubber (which the Malverns obviously wasn't) in 3mm thikness and let them stamp out a disk with 5 cm diameter(+2 on reserve). cost about 3 €

Oups, just saw on the picture that you already have

I made one out of three layers of bicycle rubber. I dont think ot will work tho as the pressure is probably too high. I cant tighten it too much.

Better that you reach out for the 3mm oil resistant rubber...no problem since.

Thanks yes. Nitrile looks like the best material. I think I will cut up some of these gloves as they have cotton for strength

Hmmm... still to soft in my opinion

Mine went the same way but I found it before it broke up. I made a temporary gasket out of 2 layers of gasket paper till I got a replacement from Morgan.
