That's what NAPA specs for a 7.3L Powerstroke. I believe that's the filter I run on my '00 PSD. Will it fit an '86 6.9 IDI? I've read stuff about Fleetgaurd filters posted by Dave S., but don't know where to buy them. NAPA seems to be made by Wix and Wix is good stuff.

 

PSD filters will fit just add 1 qt.........however the info below is the best there is.

Oil consumption, and the proper checking of the oil levels in Ford diesels comes up periodically. Ford dipsticks are calibrated for hot oil. The 10 quarts in the IDI engines expand about 1/2 to 3/4 of a quart as the oil heats up, and contracts the same amout after cooling. If you check the oil first thing in the morning ( which I grew up doing ) the engines will all indicate oils level below full, but when checked hot, will ( after a 10 minute drain time ) the oil level is usually at full. If you are checking the oil cold, and keeping the level at full, you are actually over filling the engine which will burn of the extra rapidly.

Suggestion: Check oil hot after 10 minute drain time.
Don't add until level reaches add line ( 2 quarts ).

In my days at Ford this often cured, or at least improved, the apparent oil consumption complaints.

 

I've read issues with PSD filter threads. Just trying to get a confirmation of the NAPA filter actually working. Do you not suggest running a larger filter?

When I change the oil in my PSD, I fill it up 1-1.5 qts. shy of the capacity spec., start the motor and let it warm up a bit, shut it off, let it sit for a couple of minutes and then check it.

I've checked the oil in the IDI after a long run. It was about halfway in the hatching. I added a half quart or so.

Is there supposed to be a copper washer between the oil drain plug and oil pan?

 

I use the stroke filter on mine it adds a quart per oil change.

 

Yes Napa 1734 or Wix 51734 or Motorcraft FL1995($10 @ Wallmart)

 

It was a tight fit, but the 1734 fit in there.

 

i have the copper washer.

 

I took off the weirdest washer I've ever seen. I forgot to get pics. It's a steel washer with a viton style oil seal pressed into it. I've never seen something like this before. It's hard to describe. I replaced it with a copper one. NAPA tried to sell me a plastic one.

 

Those seals were originally GM, and work fine, and are available at any parts store.

 

I am running the nylon washer on mine, works fine.

 

Do you poke a hole in your filters before removing them? The filter on this motor is cocked at an angle. I will be poking drain holes from now on.

 

When I crawl under an auto punch is one of the tools I bring. I loosen the filter first alittle bit then punch a hole in the lowest point and let it drain.
