Guys, they built the DC back when they put enough lead in the gas to kill the grass along the roadside. Have any of you had problems burning valves with the no-lead gas? Do any of you use/recommend an additive??

Ted. The worst problem that results from no lead in the gas is exhaust valve seat recession, the intakes are happy with lead or no lead. The auto makers made improvements by hardening the exhaust seats and in some engines, installing rotaters on the exhaust valves. Your Case DC has the hardened seats and if its new enough, also has exhaust rotaters. I see no need for an additive. Buick V6 engines in in the mid 70's to the mid 80's never hardened the seats and always ran on unleaded fuel. Bruce

I'm not sure about the use of valve rotators on engines using unleaded fuel. I have a friend that worked for a shop that converted trucks to propane and they always removed the valve rotators because the propane had no lubrication qualities and caused the valves and seats wear.

Having run propane dc's thousands of hours your friend is wrong about rotors on case tractors....now making a cold manifold is a plus.
