No oil in filter

[Fuddy Duddy]

My 861 runs good. Show around 40 pounds of oil pressure. Burns a little oil. But not much. Starter went out. Ordered a replacement. Got delayed in the mail. That seems pretty common these days. So it been sitting for over a month by the time the starter came in. Went out there to pull the old one. Course you have to remove the oil filter to get it out. I put a little tub under it to catch the oil run out from pulling the filter. But I was surprised. None came out. Once off I put it up side down in the tub as you would to drain it. Not a drop of oil came out. Looking inside the filter you could see it had had some oil in it at one time. Once I got the starter back on I cranked it up without the filter on for just a second. Shot out a good stream of oil. So what's going on?

Is it a spin-on filter? There should be a valve built into the filter to prevent drain back so that the filter stays full of oil when the engine isn't running. It sounds like the anti-drain-back valve in that filter is bad, or it has an incorrect filter that doesn't have that valve.

Must be the wrong filter then. It's a WIX 51189. It spins on to the side. Most filters I deal with are straight up and down. So once I pull them I turn them up to drain them. The ones that should be used are not suppose to drain at all?

You should be using a WIX filter.

You should be using a WIX filter.

Wix 51189 is the stubby filter used on some Ford tractor applications and the WIX specs say it has an anti-drain back valve. The valve may not be holding and slowly allowing it to drain over an extended time of non-use.

 

[Fuddy Duddy]

Filter must just be bad then. I don't know how long it's been since the last oil change. The oil still looks good. It was showing right at the full level. But I always check it cold. Guess the thing to do is check it. Run the engine a few minutes. Then check it again. With the check valve not working it should then be a quart low right after running? I just put the old one back on. Guess I'll go get a new filter and change the oil too. I can save the used oil to put in my 2N. It has the self changing oil feature built into it.

I have seen filters with anti-drain valves drain down over time. It may not be perfect, but I don't think it is unusual. That short filter won't hold a quart.

Why are you running that stubby filter that won’t hold 1/2 qrt
The standard filter for those tractors is the 51515

They should drain when you remove them. They shouldn't drain back into the engine when the engine is turned off while they are installed.

It seams the filter would also need an anti-siphon valve.
3 ways for a horizontal filter to be dry.
The anti drain back valve is bad or missing
The anti siphon valve is bad or missing.
The bypass valve was activated and the oil is bypassing the filter.

Then again a small seepage from the valves would manifest itself over a month from sitting that would be no problem for a motor used more often.

That happened to me too on my Jubilee.
I went to O'reillys and bought the smallest spin on filter I could find.
Now it takes less time to fill the oil filter and I get oil pressure much faster.
I don't remember what filter I buy. It's about half the size of a wix filter.
For some reason the filter sitting on it's side seems to drain down regardless what filter I used

I believe both the Motorcraft FL-1A and Fram PH8A filters have anti-drainback valves. At least that's what AutoZone says.

 

[Sean in PA]

I always use the Motorcraft PH8A on my '73 4000, and sometimes it sits for weeks, and it has always had oil in the filters when I've removed them. But I usually remove them for an oil & filter change, in which case I warm it up beforehand so the oil drains faster. But the oil pressure light has always gone out as soon as I turn the key to start it even if it doesn't actually start right away. As long as the engine is turning it has enough pressure to shut off the light within one revolution of the engine.

I buy this line: Then again a small seepage from the valves would manifest itself over a month from sitting that would be no problem for a motor used more often. Why, because that anti-drain back "valve" is no precision unit,but just a flap.

 

[Jim.ME]

You have a very good engine if it builds the 7 psi (+/-) to turn the oil pressure light off in one revolution. It is not unusual for an engine to have to crank over or run for several seconds to lift a gauge needle.

Also, with the filter mounted horizontally there isn't a lot of pressure to hold it closed.
