What do you look for in an oil filter? One that isn't glued together?

 

Faulty one way value....IMO most paper filters that I was talking about has the end caps glued on to the paper..There are an differents I was just giving my experince with the problems I have had...Thats all....

 

I'm working on an engine now... dumping kerosene in and draining over and over trying to get all the aluminum shavings out. I'm surprised to see big hunks of black plastic coming out along with along other unidentifiable pieces of stuff. What a chore, but beats cracking the cases open.
