On my restoration I put a 1725 in unknown condition into my Series III. The motor was thought to have been a re-fresh and I did pull a couple of freeze plugs to find the insides to be looking like new. I've had the motor running now several months and things run great. The motor was bought in a large Rootes parts sell off that was then pasted through several hands before it came to rest with me so there is no way of knowing what I have.
What I noticed is that in gear and with a load on the motor say third or fourth gear going up hill or at higher RPM I will hit 75 pounds of oil pressure. Normal running in third or fourth in the 35 to 55 MPH range it will run around 50 pounds of pressure and at idle could drop to 25 pounds of pressure when good and hot. Should I have concerns with the 75 pounds of pressure? In past Alpines I'd be thrilled with 50 pounds and at idle 25 would be good too but I have not seen 75 pounds before.
