so buying a used raptor and not 100% on all service history on oil changes and such, is this a pretty easy part to replace just to be on the safe side? Or is this a pretty big job?No. They are only intended to be serviced during an engine repair, such as turbocharger replacement.
They do not filter oil like a conventional oil filter, it’s just an inline mesh screen. If they are contaminated with debris or metal, that’s the result of neglect (poor maintenance) or a larger failure, at which point the screens are the least of your worries.
