Correct oil filter

Re: Correct oil filter

maybe they used a black embossed PF-25 filter on the cars then a white PF-25 filter for over the counter service?

I have only been messing with these old cars since 1962, but I have never seen a black PF 25 installed on an original car. But WTFDIK

Re: Correct oil filter

I have seen a bunch of them, but most were on 89 and newer cars, you must not ever look at later model cars, huh Dick?

Re: Correct oil filter

I looked on ebay & the net for several nights and no PF 25 W/the bottom embossed. Many have the correct look/lettering W/O the embossing. will I loose all the points if it does not have embossing? The technicall manual says "there is no conclusive evidence whether the original assembly line oil filters were embosed or not"

Late C4 (or other Chevrolets of the period) are the only place you're going to find them. I don't think black PF-25's were EVER used on any C3 Corvette----white or blue ONLY.

If you understand the judging process of the 5 or 4 areas that are used in judging an item and then the terminology of the above statement in the judging guide an oil filter that is configured correctly ( embossed or not) correct finish, is complete, installed correctly and is the correctly dated ( that the configuration or finish confirms the date ) Then full points will be awarded.

So after that long statement both the embossed and non-embossed filter would be considered correct at this time.

Re: Correct oil filter

yeah, I was just messing with ol Dick. the black ones only came on Camaros and other chevrolets of th C-3 era.the ones that came on the C-3 Corvettes 68-72 cars looked just like the ones you could get over the counter.

Joe,

It is wise to look at the date the TIM&JG was published. Not the date of the last printing, but the date the text was last revised. The words written in the TIM&JG represent the best knowledge at that time. Since Corvette knowledge is continually evolving what is printed in the TIM&JG may not represent the state of knowledge as one is standing on the judging field. Were it not for this situation we could write "See the applicable TIM&JG" for the answer to every question that is posted here.

Re: Correct oil filter

As Joe Lucia, indicated, the AC Engineering drawings added the "BEST WAY...." embossing on August 6, 1968 and removed the embossing from the drawing on January 3, 1972. There are no records that show the specific date these changes were implemented at the AC manufacturing plant or the vehicle assembly plant. Generally, engineering changes were implemented within weeks following the print change. However, in some cases, the engineering department issued deviation permits to allow a change before the prints were changed to expedite the process. Judges need to consider these conditions in the judging process.

Also, it should be noted that the application information on after market boxes can be misleading. For example, a box that shows the latest model year application to be 1970 could easily have been used in 1971 (or later). This is because outside suppliers printed the boxes ahead and kept them in their warehouse until they received a "release for shipment " from AC. Also, AC did not have a first in first out inventory control discipline at that time. Although generally speaking, the applications on the box were quite accurate, varations occurred.
