My truck runs like new with 202000 miles/started leaking oil from both ? seals

If you mean front and rear crank seals the crankshaft (main bearings) needs to be tested for wear, can see how much crank moves up/down after teardown. If excessive, seal will leak again. Also piston ring blowby can cause leaking. Check pcv system and have a mechanic check it out to give you a 'hands-on' answer/recommendiation!
