Well i decided to pop the cap and look at the rotor and such for the 84
retro van with now just 20,010 miles. thinking this is a good
maintenance interval you know 20 years/ 20,000 miles.  i was in the
process of R/R the fuel filter and all the fuel lines due to age. (BTW
how do you get to the cross over fuel lines on the top of the fuel
tank? do you need to pull the filler neck 1st then the tank? so back to
the tune up stuff. this van still had the original cap, rotor, wires,
plugs, fuel filter etc.etc.etc. till last night that is. the wire ends
were crusty but came off with no problem and was housing for many
spider populations over the years. the service ends of the original
plugs were still looking good but the corrosion around the plug was
ugly so out they came. the air filter is original also so thats on my
shopping list. i should have just known to pick one up for good
measure.  so i guess im good for another 20 years. c-ya Jonce
