OIL LEAKING INSIDE DISTRIBUTER

1989 Toyota Corolla • 135,000 miles

There a small amount of oil leaking into the distributor, the pcv was recently replaced, there are some issues with the egr valve, no praessure at all, when oil cap is removed while engine is running. The oil reaches two feet high above valve cover, recently having problems with idle but seems ok now after some adjustments, no noticable loss in power, only one small oil ring seal at bottom of distributor, questions are is the pcv valve connect to a vacumm advance which may not be working, should I have a compression check, if pistons are worn, what parts should be replaced and what would be the average cost

There is no harm in making a compression check but it would be a waste of time and money if you are not going to do anything about it.

Worn pistons requires a a complete overhaul including reboring the cylinders and pistons, bearings and piston rings.
It would cost from 2k up to 4 k depending on what needs to be done.
