Timing chain oil slinger

Almost sounds like the material varies. I would not be surprised if the factory used one type and the replacement parts makers use something different.

I've worked on 3 engines that I used for racing that had good guides and tensioners with double roller chains, not silent chains:
Mitsu 1.6L and 2.6L and Opel 1.9L. All lasted well..... but the 2.6 and 1.9 used oil pressure tensioners, not simple spring tensioners, and all made much better provisions for directly oiling the chains than the LA design.
