Re: Re: 330 desoto


Some of the early hemi's I worked on years ago did not have seals on the exhaust valves. It seems the factory's logic was the exhaust valve stems were so close to horizontal that any oil on the stems would drip off before flowing into the exhaust guides. While the engine was running, exhaust pressure would keep oil out of the guides. My first hemi, a 241 Red Ram bored out .125 so it could take 259 Plymouth pistons, would blow some smoke only when it was initially cranked. The smoke ended in a few seconds. It had no exhaust seals.

I've always pulled the heads to change seals. I've heard of guys not pulling the heads; they used compressed air in the cylinders to hold the valves shut and various levers to compress the springs.

Have you run a compression check on your cylinders to check for ring wear?
