What is the consensus now on these PF 25 oil filters that have come off these low mileage carmaros that are supposed to be assembly line filters that are silk screened black/ if one shows up now with one on the judging field , how would that filter judge compared to the white ones with red lettering?

The addition of those filters is a work in progress. What was installed on a Camaro may not have been installed at the Corvette St. Louis plant. We at this time have no proof those filter were or were not installed and as judges we work from typical factory production. So it would work out as not typical factory production at this time for finish or a 20% deduction or until we have proof that would change the standards.
So Dickie does know something.

so, no matter what else turns up on other low mileage car lines, unless a documented corvette with one will not be acceptable. since the eighties, I have always felt that the filter on the car was different than what one could buy over the counter.- Top

It would take more then 1 car from another line to make a change at this point. You maybe right on your conclusions but we need hard evidence which we do not have at this point and time. We do need someone to do the research would you be willing to take this on.

You all know, that they used a different filter for warranty purposes and not a over the counter service one. Several cars basically time capsules show up but you are not willing to accept them. Just because they are not corvettes , there is your smoking gun. Look at all the other items on those cars, one can tell they have never been touched since GM screwed them together. And lot of times we forget and think our old corvettes are something so special, when in fact they are just a massed produced Chevrolet , that especially during that time period shared a lot of components, a lot of times from Trucks!
It is really ridiculous now not to accept those filters as OEM assembly line installed.
Just like the over the counter battery, have one on EBay for like 999 dollars. We all know that battery is not close to looking like what was installed, the painting of the script ect..
I believe its time to accept the filter we been fooling ourselves to long, now it seems like we are in denial.
Need to update the old manual to reflect the black AC Delco embossed filters as OEM assembly line.- Top

I do not know that. I do know that this was done during part of the C4 era but I do not know it was done anytime during the C3 era. It's possible it was but I have seen no evidence of it.In Appreciation of John Hinckley- Top

As Joe stated we have no evidence they were installed on any 69 and later Corvette. If you have evidence to prove other wise bring it forward so we can update information that can be proven. We just can not assume that what occurred at one plant happen at all plants. So the burden of proof falls on you and any other member wanting changes to a judging guide. We all want the correct information on the assembly of these cars but with out evidence no changes will occur.

Your in denial also, then if you take the C4 evidence and not the camaros filters then. They would have needed a way to prove oil changes during that same time frame for the warranty. That is not something that started during the C4 era.- Top

I have no Idea why you think that is a ridiculous statement, when in fact if they could show you had abused a engine during the warranty period with out ever changing the oil, so they could get out of paying for a warranty is not ridiculous.
