PF48E Oil Filter FAIL ACDelco Ecore

now back when I was turning wrenches at work before I got into the inventory side. we had idiot parts changers in the shop that for the life of me couldn't figure out how they got some of the equipment filters so tight without any sign of dents or crushing on them. them dam things were so tight even driving a bar through the filter making a T handle would only rip it off the base. many times I had to use a hammer and blunt chisel to get the threaded part of the filters off.

I guess they learned their lesson, at least I hope so when the guy who last changed the oil got to pull the filter again on the next change.

shortly after I got into the inventory side, I had the shop manager coming at me for defective filters where we had a string of them blowing out the gaskets. LOL I reminded him of the day he chewed everyon's arse for hulk-ing the filters on, told him now they are leaving them too loose. there is a proceedure out there, make sure there following it. the Fleetguard and Donaldson reps are gonna ask if they are following it, probably gonna want proof too! "you know what you got out there" HAHA he walks out into the shop and gathers everyone up.....
 
Oh yeah a pic. Just can't miss this river.

"And I thought Diesel engines left oil spots you couldn't get off!" That's frame wax on the top: GM dealers will remove the frame wax by the cats and paint the frame.

To close out the question of leaking PF-48 Oil filter: This van went through FOUR oil filters all leaking/loose before one year or an oil change light tripped (generally less than 3000 miles for a leak.) AMSOIL, Wix, AC Delco, brands all leaked. All GM Dealer installed during an oil change or filter replacement after leaking without an oil change. I only supplied AMSOIL once as the dealer supplied and used Wix or trouble vehicles generally with Wix fixing the problem. The GM dealer after a long conversation with the service manager finally replaced the oil pan that has the oil filter mount in it. Didn't keep it long enough to say 100% that it fixed it however it wasn't leaking 1000 miles and time later when the LEMON van finally went away.
