off side mag chain cover VH

[charvey]

Hi All
Just got back from a run and noticed a small amount of oil below mag chain cover renewed washers round rocker feed and pressure valve but still had a small amount of oil at the bottom of the cover got a feeler gauge and found that I could slide the feeler gauge under the cover gasket,
Took of the cover to find that one of the two centre screw bosses was above the height of the two outer case rims checked with a straight edge.
took the whole case down flattened it on some wet and dry on a flat surface new gasket including gasket washers on the centre bolts all tight and no leak and cannot push the feeler gauge in any more should have checked before but there you go, I have checked another cover and have found the same thing so easy to miss, Clive.
