Telling someone not to worry about oil pressure is quite possibly THEE worst tractor advice I have ever heard.(quoted from post at 22:38:38 02/09/15) Don't worry about it. As long as it Picks up oil and makes pressure and don't knock. These oil gauges today aren't a quality control item. Its low cost slam bam get it out the door and get paid type thing. I had an 8n and with 3 different gauges had 3 different pressures. Take ur pick.
(quoted from post at 09:42:16 02/10/15) "There are 1000's of these out on the ranch or farm running 12-25 psi."
This statement I would agree with, and, if that were hot oil pressure it would be acceptable. Great at hot idle.
But we don't know whether the tractor was hot or at idle or
cold and at full throttle. Big difference.

Well - I would say, IMO, telling someone to pull using the top link rather than a draw bar to be worse advice - but that is another matter. (grin)
To the question at hand - 18 psi at idle either hot or cold is darn good for this low RPM flathead 4 cylinder engine. I did a very complete engine rebuild 48 8N and palsti-gauged every bearing, rebuilt the oil pump (including new bushing), and replaced the oil gauge and I am getting about that reading now (was at about 5 psi before the rebuild). I completely agree with TOH, but my threshold on when to really worry is 5 psi at idle. Your mileage may vary.

Possibly, but even though I've seen it done, I've never heard that(quoted from post at 10:35:55 02/10/15)Telling someone not to worry about oil pressure is quite possibly THEE worst tractor advice I have ever heard.

For hot oil pressure that would be acceptable.(quoted from post at 08:27:41 02/11/15)(quoted from post at 06:42:16 02/10/15) "There are 1000's of these out on the ranch or farm running 12-25 psi."

after 1hr of working it is around 18 to 20 this is a hot engine even a fast throttle still the same maybe 1 or2 more psi
