Had the car seviced a couple of weeks ago and have been using every day since.Noticed that the oil pressure from cold is about 60lb,when driving along at 2500rpm pressure is 40lb.At idle 850-1000rpm pressure is between 28-30.Cars done 32,000 mls.Do i need a new spring relief valve?
Sounds like a new spring is needed, and is easy to fit. Changed mine about a month ago the pressure now is cold 80, warmed up 60 and after abuse55/60. I think there around 4 to 5 pounds.
