Not easily finding leaded gas and wanting to avoid adding lead additive every tankful, I was wondering if anyone knows if my 318/auto had the hardened valve seats. This was just about when manufacturers were making changes to allow engines to accept that new unleaded stuff.
Even if it does have the soft seats, will I realistically be doing damage to the engine if I run unleaded (I put less than 5K/yr on the truck).
If the advise is put in hardened seats, what is involved? Is this what a person of modest :) mechanical aptitude can do, or is this a bigger deal?
Thanks,
