Was told oil relief valve in vehicle might be open after noise from car after oil change,will it shut on its own or does it need replacement
Hello - usually engine vibration will release a stuck oil pressure relief valve stuck in the "open" position. Sometimes tapping the engine block area with a small hammer will allow the spring-loaded piston to release from it’s stuck position. In a "worst case scenario", a mechanic can remove the access plug, physically extract the spring and free the piston from the stuck position. I would pursue this with the oil change folks, then my own mechanic if I trust them. For a trusted 2nd opinion, I recommend an engine inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.
