Hi Grumpy and Roebuck, have done a compressionand, 115 psi which I think is good. Top crankshaft oil seal is still intact and tight no movement at all. Have rechecked the ventilation compartment and wire filter and hole,all clear. I put about 5ml of oil into filter area and was able to see it drain through ventilation hole, done this 3 times just to be sure.
