PF-25 Oil Filter Judging

Re: PF-25 Oil Filter Judging

You are right at the change over. IMO, a non embossed would be OK as would an embossed. An embossed is more expensive. You would want to get Paul's opinion on this. Now, as for finish, that's a whole 'nuther discussion. I'm sure the finish on this one would work just fine for judging. The one from Paragon will result in a points deduction. It isn't accurate.

Disclosure: this is not mine and I do now know (as far as I know) the seller.

I have paged back and forth between the ebay example you were kind enough to send and the Paragon part # 2137. My unpracticed eye did not detect any variances in finish, color or lettering. In the interest of assisting me escape from rank amateur status, what differences did you detect? Many thanks...Clark

Clark,
The reproductions have a painted bead at the top. Of course that is easily removeable. My best description of the two is that the reproduction will look "over restored" The white is shiney and the silkscreen is well painted with very crisp edges. The originals are not. In addition the bottom 'flutes" can be different also.

No problem, Clark

First, look at the bottom of the repop and look at the flat circle on the bottom. Look at the circumference. After that, compare it to the same area on the real one. The real one's diameter is, at least, double.

Clark, to help you see the difference in the filters that others have described I attached a picture of a currently available reproduction and a reproduction from the late 90's. Note that both have painted beads. The difference in overall lenght, fluting and gloss of paint is evident. I don't have an original to include in the photo.

As in most cases photo can lie to your eye seeing it in person and the picture comes into focus. Paragon has the white filter in a white back ground so the details are nonexistent. As the others stated look at the configuration differences. The current reproduction filter losses 5 or 60% of the 8 originality points due to Configuration, Date and Finish the only credit is it is Complete and Installed. I know it is 62.5% but 4 = 50% I give more credit for original ones.

Re: PF-25 Oil Filter Judging

Got it! Taking a second look at the photos after your collective comments causes the variances in the filters to really jump out. Many thanks for hanging in with me on this...Clark

Re: PF-25 Oil Filter Judging

Terry, on the filter, just like this thread talks of Chevelle having vastly larger production numbers, same applies for factory installed 212's.

The evidence is very well substantiated, forget about those horizontal jobs on Corvette's, there are NCRS members here that still have their original C3 Corvette's and pictures new that show diamond's.

I didn't think diamond was the 212 air filter issue for early C3s. Expanded metal or wire mesh is the debate, I thought. I would be happy if there was a solution, but I suspect that a difference betwen over-the-counter and factory installed existes for air filters as it does for oil filters. But that is just my 2 cents.

Re: PF-25 Oil Filter Judging

Terry, expanded metal in the form of diamonds. One thing a lot of folks need to understand about high volume manufacturing is that you would not be generally making these one way for service and another for the factory, other than...there is one part number for the filter, and in bulk, 20 packs, or a tote they go to the factory, when you put them in a box, material control buys the filter, they buy a box, they put the filter in the box and it goes to the customer.

That has been pretty well substantiated for air filters, oil filters, pcv valves, for oil filters the printing gets in the mix, mostly for Brand Image, I doubt warranty for blown engines had anything to do with it because I was there with blown engines and we easily could tell if someone ran the car w/o oil change past the point of no return. Its easy to tell and the subject of other threads. There again the base oil filter construction to the point of a white filter would have been the same. There are people out there with the documents too, time for a little sharing.

That one exception is the CX filters and associated Performance Parts they sold as a specialty line.

Re: PF-25 Oil Filter Judging

I was not aware that we agree ont he expanded metal for early C3 212 filters. I am glad we can agree on something.

Same product, but different packaging, is not the story I get from the folks who worked in dealerships back when -- but their voices are getting fewer and weaker. No doubt the packaging was different for the factory (as it was for so many items on the car), but I can absolutely prove to you the filters for both my 2008 Corvette and my daughters 2006 Malibu Max are different between the assembly line and over the counter equivalent in minor ways. I did the first oil change on both and have the original filters for both, and both have minor differences from the same OEM filter in bulk packaging. The differences are in labeling, and not the basic construction, so we may be saying the same thing in different terms. I am pretty sure I posted the pictures of the Corvette oil filter on here in the past, and can do it again from home but C6s are a long way from the topic of this thread. I believe that the basic principle was the same regardless the reason or the generation of the car. It would indeed be nice to see the documentation you reference so we could have a definitive answer rather than speculation.

Terry, the English language morphed a bit from its continental origins to the throne and the islands to the north, let alone the colonies so its a pretty close alignment.

Anytime you're in MI, your 4 hour limit within state lines permits, or the phobia of same is over ridden and you stay longer, given my phobia of same has me there at the same time
