Re: Oil Scare - Universal M25

Good to hear you got it fixed and it was the inexpensive option.

UPDATE: The solution to this puzzle was the SENDER, as TQA pointed out in post 2.

Re: Oil Scare - Universal M25

After you worked for an owner of a LARGE sport fishing boat and HUGE Mega Yacht who has MIRRORS installed under the engines in the engine rooms, and you wear latex gloves when working in there, like a surgery room, everything else seems dirty, including my engine...

I would have been fired if the engines on the boat I worked on in College looked like my engine... We're talking Pebble Beach Concourse clean......

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

Top End Rotella T Exclusively Since New:

And the hours when the pic was taken:
Agree with Maine on the ROtella T. That is all that goes in my engine. But mine hasn't turned red yet. Mine is still silver and grey. Hey Maine, how long before my engine turns red and shiny like yours and not black and greasy like it is now???

Is it just me, or does everyone else here feel inadequate when Maine shows picures of his shiny engine???

Is the pressure sensor electric and functioning properly?Pressure line to real pressure gauge tells the truth.

Maine - Rotella T it will be for the next oil change - probably next week!

BTW - do you eat off of that engine? You could!

Thanks D-

I read that post as well... However, IIRC, that poster had consistent low (no) oil pressure with 3 non OEM filters. (S)he then tried a genuine Universal (gold plated) $30 filter, and the pressure magically returned.

My symptom is that the oil pressure dropped as the engine heated up.

The symptom seems to be gone, now that I have changed the oil and Filter (I really like the Bosch filter) but I won't really know until I try motoring for about 2.5 hours.

Good idea, but no. The crankcase oil level was spot on.

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

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.
