I have a 1974 Chevy Monte Carlo 350 rebuilt motor. It has been sitting for over two years. Well I decided to use it and I just adjusted the lifters and I made a tool to prime the distributor to get the oil to come to the lifter. Well only one side is getting oil one whole side doesn't get any oil what so ever. I ran my drill for 10 minutes and still not one drop on one side. But it comes out fine on the other side. Please help me with some suggestions.
