What should I look to fix concerning lifters and oil pressure?
Same thing. Change your oil a little more frequently and use the correct weight oil.

Substitute a qt.of Marvel Mystery Oil, in place of a qt. of oil next oil change. MMO cleans parts, and makes things seal off, as they should. Read the directions. It works both in your oil and with your fuel too! See some of these in this link
Mechanical wear, as well as "build-up" can keep your Tappets (hydraulic lifters) from sealing correctly.
See this one too
Let me know if you see a difference
