Timing chain oil slinger

I used a melling tensioner on my 5.9 magnum. Had about 1,000 miles on it when I tore it apart for a cam swap. The chain dug into the guides and sent bits of plastic through the engine. The crank journals were fine but the soft bearings were pretty trashed. I'll get pics when I get home later.

I have a tensioner on my 340. Had to pull the cover after 10k for a leak and no wear. Running a Cloyes timing chain. Had to pull the cover and replace it at 18k and again no wear. Maybe I got lucky. Have heard of this happening before.
