I unfourtunately have a collection of oil coolers that havew seen a little bit of metal in them. I have been looking at it and how it goes with the filter. By looking at the anti flowback flaps it appears that the oil goes through the part that would be contaminated before it goes to the filter and then back down the hollowed bolt back into the motor. IIRC that housing is the first place the oil goes after the pickup and pump. So in theory wouldn't the filter catch anything that would be missed durring a cleanup? If so wouldn't that mean it could reused without much worry (of course cleaned first).
I know throwing it out is a common thing to do and I am just wondering if my thoughts are flawed or not. Those things are hard to come by and a grip at the dealer.
