lol, i was told long ago that if these old cars are not leaking/dripping then time to add oil :)

no gushers but a drop here and there for me.

also make sure the levels are correct and NOT overfull. overfill trans, leaks into the u-joint then down the tube to rear end then down the shafts out the ends onto brakes and all :!

not really many seals on these old cars
