Probably the Ericson Owners Group... See thread here; Oil pressure problem?

Also note that I already checked the valve, and it is clean. I may replace the spring, as pointed out in the Ericson forum.

Because the pressure is better since the oil change, I strongly suspect the viscosity of the oil that I added last fall did not match what the package said.

Another tid-bit to chew on; the engine water temp never went over 180.

...and for the guy in the Ericson forum that couldn't find the relief valve, here it is;

For low rpm check your air intake, the screen or filter may be blocked. You might have a faulty op sender if the alarm didn't go off especially if the temp didn't rise. 10m is fine for the filter, but I'd be looking for something simple first.

That wasn't the thread but the info is the same. Evidently this problem is not uncommon on Universals.

FWIW the C34 tech wiki at c34.org has a lot of good info on these engines.

Re: Oil Scare - Universal M25

If changing to a different oil solved the problem the original oil viscosity must have been WAY off from what was printed on the label?

Re: Oil Scare - Universal M25

Forgot this, if the crankcase was overfilled perhaps the crank was turning the oil into froth?

Re: Oil Scare - Universal M25

E, I don't know where I read it but someone had the wrong oil filter and after installing the right type the oil pressure returned. I'm guessing that happened to you.

Re: Oil Scare - Universal M25

Are you sure the Motorcraft oil was a "C" rated oil not an "S" rated? I know Motorcraft makes one but I know my local Wal*mart does not carry it.

I have one word for diesel oil..... ROTELLA T !!!

That is a great idea, and I shall check the air intake...

However the engine will hit 3K RPM in neutral, but not under load...

I am fairly confident that the oil pressure sender is working as it should.

Yes, I have the C36, C34 and C30 websites bookmarked on my home computer. I am on a business trip this week in Chicago without my personal laptop. (Will I ever be able to retire, and do what I love, instead of having to do what other people want?)

The Ericson owners group is also a good one. A couple of well known posters from this forum used to hang out there.
