what is normal oil pressure?
I have a 70 LT1 that is very original, Lately the oil pressure goes to 70 lbs . I checked with a different gauge, and the pressure showed 75 lbs.
after warm up at idle, it will drop to 45 plus, but goes right back up when when giving it some throttle.
What would cause this?
Oil is 10w 30 Joe gibbs driven oil
Would a motor flush help?
