I just put a new oil pressure guage on my newly rebuilt 8N today and it pegs the needle at start-up and after warm up. I have read the archives and didnt really find any useful information. Can this excessive pressure harm my engine or other components? Everything is new and clean. Oil pump to lines to guage! Any help is appreciated. Thanks!

Dave

I don't think that the excess pressure is anything to worry about. I have seen some hundreds models blow out the oil filter when the pressure relief valve sticks but have never seen any damage caused by too much oil pressure in the N engine. It's for sure you aren't going to blow the oil filter on the N because it is not a full flow filter and just a bleed off of the oil gallery

Has the oil pressure relief valve been altered or it's spring?

The notch on the side of the relief valve is supposed to be there to allow some oil to always be able to escape the pump.This aids in priming the pump.

Is the gauge designed to read 60 PSI or better?

I have not altered the relief valve or spring and I doubt that the dealer I bought the motor from did either. This guage is the guage the dealer gave me for a replacement, it had a 9N... part number but was aftermarket. I think it reads to 50lbs. Thanks!
