I am getting quite a bit of sump oil coming up from the crankcase breather tube. The engine has had new rings fitted and the compression when hot are Ok at 100 psi for each of the cylinders. I hope this improves with a bit more running, but the oil is actually building up inside the fibre glass air cleaner fitting. So far the engine has probably done 15 hours running. It seems to drain most of the oil back down the tube again but there is a layer of oil in the housing that cannot escape. Reading Judsons comment on blow by it seems to be a documented problem, but I am surprised how much oil is getting blown up. Has anyone else had this problem with a fresh engine? Thanks Tony H.
