I am giving my old engine a run over and discoverd that the bearings of my cam shaft did not fit tightly onto the cam itself. So I orderd new bearings thinking the old ones were worn out on the inside. Now I put the new bearings onto the cam only to discover that they still have the same free play on the cam again. Are they supposed to not fit tightly Or has the cam itself worn out where the bearings fit over I am dutch and not a wizard in tecnical jargon. I hope I am clear as to the problem. Who can help out here.
