Valve chest cover leaks - again!
#4
I found that if you fill the grove , normally used for a cork gasket , with silicon and leave for a couple of days to fully cure. (get the surface as smooth and level as possible  which may take a couple of coats ) Then cut out a card gasket , which should be a full cover not just edge type, cut holes for the securing knurled studs  and  drain holes at the lower edge to return any oil to the tappet chest, smear the cover sealing edge with fresh silicon and do the same to the block face , ( note, just a smear) assemble  and tighten securely , all should remain oil tight . As an extra precaution I have drilled a small hole in each knurled nut and wire them together to prevent unscrewing.  You may still have some  oil misting but no leaks.
