I got my suffolk engine running well after over six months of trying, turned out the oil splasher had broken off and was lying in the sump, i removed it and solved the problem. I have now noticed an oil leak from the sump, not the gasket! It is from a hole/bore that im not sure what it is for but it is supposed to be there. I havent had a good look at it yet. The leak is near the draining plug, Any suggestions on fixing this problem or is a new sump the best idea?
