I looked at your site and couldn't find any pictures of your 68. Might you post a link for me/us to see your Imperials?

During that time, it has always run on unleaded gasoline without use of lead or octane boosters. Earlier this year I opened the engine to perform a valve job. I saw the hardened exhaust valve seats, and no valve recession. My DeSoto went back on the road within the last three weeks. It has about a tank and half of low-grade Sunoco, and is running the best it ever has. Once I get new tires installed, the DeSoto will be taking even longer, faster trips. The only additive I will take along is Chemtool, which will help with carbon deposits. Dave Duricy 1950 DeSoto Custom club coupe 1968 Imperial Crown covnertible 1973 Imperial LeBaron desotoland.com >
