hi i change oil and filter iam get 50 plus oil pressure and than after eng warms up it goes back to around 42 psi i think one or more holes in eng.or lines are plugged i seen cd2 a oil treatment stuff and i wonder if it will unplug the eng thanks hoppy

 

50-60 psi under acceleration or cruising is normal, 30-55 psi while idling is fine. Don't worry.

 

Yup, nothing to worry about. As oil gets older, it will thin out. It is normal to have higher oil pressure on new oil.
