Is there any visual check to tell whether a 6cyl engine has had valve seals upgraded to take unleaded. If not is there a recommended supplement for regular unleaded to prevent excessive wear?
 
to my knowledge you cannot see without taking the head off, as all the conversion is is that seats are fitted where the valves sit in the hed, they just look like washers that fit perfectly if that makes sense. any good motor spares will sell decent additives.
