I just bought this filter from rockauto. I noticed it has some glue "baked" on it in two different locations by the gasket. I wasn't able to scrape it off.
Would you run it? I've never seen this before on a filter...
I would run it-if you can't scrape it off it's unlikely that hot oil would take it off. Plus, if it did break loose, it's on the inlet side, the media would catch it.
I am sure that is the same glue that holds the whole filter together. If you are worried about that coming off, I would worry (not) about the whole filter falling apart.
