Do the easy fixes, dipstick o-ring (it's literally one 10mm bolt and the whole thing wiggles out) tighten down the valve covers if they are leaking or replace.
Changing the crankshaft seal is not a simple job. Also, that oil leak is not hurting anything at all and does not affect the reliability or drivability of the vehicle and is a common leak point. Some even leak from the oil pan, which requires either the engine to be pulled or the entire front end taken off just to drop the pan. If you want another opinion, do the easy stuff and things you were going to change anyway and leave that leak alone.

another small part, if replacing valve cover gaskets, is the oil fill cap has a rubber gasket as well. When I did my last vc gaskets, I replaced that gasket as well as the dipstick o ring. Both are not major leak makers, but figured Id replace them anyway while I was in it. The old oil fill one was hard as a rock and at first I thought it was plastic and part of the molded plastic cap. I dont have the part # handy.

I have to change the timing belt soon and am debating if I should do the extra work to change the crankshaft/cam seals since I will be in there, plus it will come with the timing belt kit......

Old engines leak. It's probably the crank seal and dipstick o-ring. The o-ring can be done now, but the crank seal will need to wait until your next timing belt job. Once you get in there then I highly recommend doing the cam seals too.

I agree with above. I know a lot of people dont change them till they leak. My rig uses no oil yet its hard for me to imagine they are not seeping a little right now. My next belt is due in about 20k miles, which is also at 295k. It will get it done sooner. It will get new seals Will also do oil cooler and the hoses related, as the parts are now 20+ years old and nearly 300k miles.
Similar, when doing upcoming vc gasket job and all that is opened up, any water hose under intake etc, ( hard to get to) is getting replaced, as those too are very old.

Just from personal experience, I can tell everyone that 20+ years and the crank seal leak will take a toll on the harmonic balancer.

once i fix my fuel tank issue im gonna tear into the motor do vc gaskets and tb/wp job with some help from a mechanic friend. I already bought the crank and cam seals+plugs a couple weeks ago so ill get a dipstick tube o ring and we'll be good to go. Gonna do some serious engine cleaning when we get some good weather before we get to work on it.

where is this oil coming from?
I had a dipstick tube o-ring leak. Here’s what mine looked like. There’s plenty of people who say if it’s not leaking, don’t touch it, but these cam and crank seals are 20ish years old and easy to replace. Just use OEM and you’ll never have to do them again.
