Oil filter ? PF970C
So I was looking thru some of the parts I have and found 3 PF970C
#25014155 black oil filters That when installed the label will show upside down. Is this just a mistake.

Re: Oil filter ? PF970C
Thanks Lou,
Does anyone know if there any of these installed new on the LT5? or were they just a replacement filter issue.

Re: Oil filter ? PF970C
I recall all LT5 engines from the factory had black ones. I was able to buy them at the Chevy dealer during the early 2000?s. Then they changed to the blue color, but either the same PF970C label.

Re: Oil filter ? PF970C
The ones you and I have are the ones installed at the factory.

Re: Oil filter ? PF970C
I have several old black PF970C. Are these safe to use when they are 20 + years old?

Re: Oil filter ? PF970C
They are not safe.
Likely could burst into flame at any moment. I can safely dispose of them if you mail them to me. Why risk catastrophe? Happy to help! Better mail them quickly.   Marty p.s. I have observed no degradation of stored filters or their performance. I still offer and use them, although Mystic's method of removing the label from new Black Bosch filters is visually almost as correct except for NCRS and is what I often use on my own car to "save" the originals for what I don't know. |

Are there any photos of them with the label in this manner from the factory? Or were these only the over the counter filters?

Re: Oil filter ? PF970C
We know they were through 93. Next time a low mile 93-94 is up for auction, we can check it out.
