Well, I've decided to re-paint the engine on the Nash over the winter. Because I have limited space, I would like to leave the engine in the car for repainting. So here's what I'm thinking... The valve covers, intake, exhaust manifolds and distributor can be removed, along with the water pump. That will give me more room in the engine compartment. But, before I do that I figure I better degrease the engine with some parts still on so I don't get water in the engine. The engine doesn't have any caked on grease, but it is dirty and oily from normal wear. I do have the dizzy already out along with the exhaust manifolds. I can put them back on for degreasing, but would prefer to cover the holes somehow instead. Any suggestions there on what would work best for a seal? I'm thinking about spraying down with Simple Green, using a toothbrush to scrub and then spray off with water. Not sure what to use for final wipedown before paint. Any suggestions on the process from beginning to end would be appreciated. The paint on it now is in pretty good shape so I will probably need to scuff that too???
