The first & easiest thing to do is a compression test. Check each cylinder dry & record the results then check each cylinder after squirting about a tablespoon of oil into the plug hole. If you see a big difference in one or more cyl.'s you're going to want to pull that head to find out why. If all cyl.'s are close & you get better with the oil but still close, you're just worn out & probably need a rebuild. Worn or cracked rings could cause enough blow-by to fill your intake with oil through your pcv valve. My son just had his#4 wrist pin shift on him that gouged cyl. wall beyond repair. The rebuild only had about 2k miles on it. He's pretty pissed at the guy that installed them for him. Now it's either resleeve it or throw it out. The oil only being in the #2 port seems a little odd but could just be a bad valve stem seal. This only a theory but bear with me. As the piston nears the bottom of the stroke it slows down. The air is still moving fast & when the valve closes it dead-heads against the valve, builds pressure, & then reverses direction, possibly taking some oil off of the valve stem with it. That may sound like a stretch but it would be easy enough to check out. After 15 yrs. you're probably due for seals anyway. Again theory but you're #2 seeming a little hotter may be due to the crack in the manifold causing reduced back-pressure. Good luck. Let us know how you make out.
