Should I be worried or happy?

I dont know whether to be happy or not, I replaced my pcv valve after letting it go for 70000 miles and the inside of it was clean, my truck has 78000 miles ona 3.slo and I hope it is a good sign.

that 3.slo is funny, ever driven a 2.3 of the same vintage? you can run faster.
The mid 90s must have been good years for ranger reliability. Not unusual to get that kind of mileage on the pcv. My 97 got its 1st major tune up @ about 186k...for real. I bought used @ 90k or so and assumed it was gone thru at some point prior because it ran so well. Started getting crappy gas mileage and hard starts so figured it was time to give it a tune up only to discover original factory motocraft wires and plugs (8 mind you, never noticed b4). Plugs were tough to get out but hadnt seized.
Other amazing mileage feats:
orig timing belt: 200k, some cracking but still pliable
water pump: 200k with timing belt
hoses: same
brakes: rear drums still not done, front pads @ about 150k.
shocks: about a month ago @ 210k, orig with factory tags yet. easy off, a little pb. Shocks were basically not functional, nice change to skyjackers.
clutch, flywheel, starter: around the tune up, maybe 190 or so.
This is easily the most reliable, albeit slowest, vehicle I've ever had. Just about 215k now and doesn't even use oil between 4000 mile full synthetic oil change intervals.
Check engine light on intermittently now, think its o2 sensor, wouldnt be surprised if thats original too.

70000 is nothing, emissions related parts are still covered by warrenty to 100,000.

Only in CA, Federal IM warranty is only 80,000 unless the manufacturer or dealer voluntarily extends it.

PCV is pretty simple anyway, it's the blowby that's significant and shows if the PCV is clogged, so congratulations.
