Big oil leak after 26 years city use

[Goce]

This car has been in my family since early 2000 and now is been driven by my father. It always has had very small oil leak, drop or two a week, never thought much about it but from january oil leak increase sustasly, it leaked 1 liter of engine oil in less then 30 days so i decided to pull the engine and box out and do a full service and reseal the engine. Removing the engine wasn't too hard, i've grown up with those cars so 5-6 hours it was on the ground and i separated the gearbox from it, biggest disappointed was the flywheel is in much worse state than i thought, is worn 0,12-0,15mm and i can see it wasn't machined straight from the factory, i have couple more flywheels from the spare engines i have but they have 0,02-0,05 mm worn, i'm not sure is that acceptable or should i just chuck it up in my lathe and resurface it? Also the cam oil seal was replaced with the timing belt less than 50 000 km ago and it has failed and soaked the belt in oil, so new timing set as well.

Is it a stepped flywheel?  I'd resurface regardless since you have the equipment to do it either way.

It's easy enough for me to resurface the original flywheel it has no heat spots but i'm concerned with the balance and how straight is it. This car has had a very bad shaking when setting off with 3 different clutch sets. Its is a stepped flywheel with 1 mm of positive pressure against the pressure plate i'll ether reuse an old known good flywheel with a used clutch for go all new and resurfaced flywheel, i've got so many good used parts for those models, its a west to buy new ones and throw away them.

It's been a week since this car is on jack stands but i did managed to buy all the consumatives and do some of the work, did replace all the oil seals and o rings, found out that the vacuum pump mounting flange is bent and the o ring can't seal, lots of hand filing did fix it. As for the flywheel i did decided to use an old known to be good also an old clutch and other components, new suprase come when i went to fit the clutch release bearing, the slave was to beet up that looks like splines, the previous flywheel sure had some issues, it's a lot more effort pulling the whole engine and box out but makes doing more repairs at ones lot easier, this car isn't leaving my family so everything is getting done right.
