Because I blasted and sanded the engine block in prep for primer and paint I had sealed off the intake and exhaust ports so before installing the intake manifold I needed to clean up the port surface, take out the paper towels that I had stuffed in the ports and then vacuum out the ports and blow out spark plug holes and give the cylinders another shot of Marviel Mystery Oil before to turn it over again to find cylinder 1’s top dead center. I also need to put some oil back in the pan, run the oil pump to build pressure and then change the oil and filter before I turn it over with the starter and check the compression again.
