AC Delco PF-25 Embossed Oil Filter

Re: AC Delco PF-25 Embossed Oil Filter

Remember when quoting these prices that people can ask whatever they want for an item. Its value is determined by what the average selling price is. Even one item selling at an astronomical price does not make the market.

To amplify on what Patrick stated about points per dollar: All you need to do is gain 10% of the originality points in order to garner all the condition points. You would have to work very hard not to get Installation points and that should be 20% of the available originality points. Go to your local FLAPS or big box store automotive section. Ignore the orange painted filters and find an AC Delco filter. You will lose configuration, date and finish, but should get Complete and installation. You have 40% originality and should have all the condition points. All for less than $10.

Now if you want to show off to a few (a very few, because who is going to go under the car to admire an oil filter) then spend the big bucks. But then there are those who would spend the big bucks to test the judges. Who would do that? Don't answer Dave S.

No one drives an L-88 on the road, but the owner wanted zero chance of failure!

I tried swapping oil filters at a meet once. That was a real mess.

Patrick------

Well, there may be a few L-88's that are other than "trailer queens". However, I was not directing my response at the original poster but rather to the "broader market" for restoration in which cars are used on the road.

It's very messy to change an oil filter, especially if the engine has been recently running. However, one does not have to change the filter on the judging field. The change can be made before taking the car to judging. Even if it has to be used on the road and a 50 year old filter is used, that's not going to harm the engine in any way, especially if the oil is fresh (as it likely will be in a rarely driven car).

One can even do better than the standard blue AC Delco filter (which, incidentally, is no longer offered in PF-25 size in the regular product line). Simply obtain an AC Delco "Classic" PF-25, GM #19187300. It's PF-25 size and painted white with red and blue silk screening. About 20 bucks. Of course, it won't have the bottom embossments but it will be an AC filter, as-original, and will have most of the appearance of the originals.

Also, keep in mind that all 1968 Corvettes as well as many/most 1969's did not use the PF-25 filter. They used the PF-29 which was longer than the PF-25 and had no bottom embossments.

Terry,
As noted you have put all this in proper perspective as usual. Many of us like to chase the details. I have lots of company. Names withheld.!!!!!

The 84-91 PF-25's had a black -silver decal on them. What is the decal on the 70?

John
No decal on the 1970.

It was coated (I am not sure if it was paint or powder) white. The labeling around the middle was red & blue ( some believe the assembly line filter had black lettering). For part of 1970 production the bottom of the filter was embossed as James G has illustrated._tr0f-PQ.jpg

This is the best I can find at the moment, but it shows just part of the blue lettered instructions. The red AC logo is around facing the engine in this image. Full disclosure: This is actually a reproduction filter, but one can't tell that from this image.

I found this in my basement and I don’t remember how I got it. It’s embossed. I always thought it was a reproduction. We’re embossed ones ever reproduced or is this an original?

I would opine that this is an original. I don't think the embossed style filter was ever reproduced.

Re: AC Delco PF-25 Embossed Oil Filter

IMHO That is an original embossed, I have never seen any repro with the lip unpainted.

Joe - The reproduction PF25 has a "dime" sized impression on the bottom of the filter... which lost me 3-5 points IIRC.

The Blue A/C delco PF25 filter with the business card sized label from the late 70's-80's has the correct sized circular impression(approx silver dollar sized) on the bottom and can be had for $10-$20 on ebay. Paint it white and label it. ZERO point deduct.

Here with the tape removed and lightly sanded on the mating line.

This this next edge view is from the 5 o'clock position in above photo - the differing colors grey/black make the mating appear uneven, it's smooth, the excess epoxy was knocked off with a quick hit from a 2" DA.

A little smoothing and blending with a coat of primer on the sanded areas then white paint...

All in I will probably have 2 hours in this finished filter plus 20-30 materials. My labor rate makes that a $350 oil filter.

Not exactly EASY however given their price and the actual ability to function as a filter due to age I see no other choice for myself.
