There will be a small oil hole in the rear of the distributor just above the input shaft. Oil cup in the front of the distributor. Lubricate both with clean engine oil about 3 drops into the cup and 5 drops at the rear. Once installed the rear oil hole will be lubricated by the engine pumping oil, so it needs no other attention.
If you can get Marvel Mystery Oil (MMO) add the correct amount to the engine oil,it may help with compression. Both with valve movement and piston rings. Compression may also increase after driving the car more.
