Hi All!
I`ve bought used oil filer housing with cooler. Found pretty much shavings in deep of cooler and housing valves holes. Shavings seems is copper.
Is this from journal bearings?
Is it possible to clean cooler or I should to buy new one?
86 the cooler. Safest route. Every diesel engine I have ever worked on if the engine has a failure and gets solid contaminants through the oil, most manufacturers recommend to replace the cooler too.
