I see this type of failure on early
2.0 fsi engines flat tappet for high
pressure fuel pump. Intake cam has 4 lobes on the end. Destroys
The Cam and tappet, similar fail
pattern to a standard v8. Moly disulfide is a good additive, reasonable. Diesel oil non synthetic is a good solution for older engines, has better amounts of zddp and phosphorus. Never had problems until dexos, attribute most hard surface failures to lack of solid film lube, just my 2 cents
