New modified oil slinger
Chrysler didn't put the slinger there to oil the chain, oil slung off from it misses the chain entirely. For decades the front main seal was simply a rubber washer glued into the metal seal shell. The engineers knew the rubber washer stretched over the dampener nose would develop splits in less than five years and used the slinger to keep the seal as dry as possible. After the introduction of the radial sprung double lip seal the slinger was found to no longer be necessary. I haven't installed slingers since 1985, no seal leaks and no chain/sprocket problems. The chain and sprockets get all the oil they need from the front cam and front main bearings, and a bit of dribble from the lifter galley during stops. The sprockets themselves act as slingers to oil the chain. The dribbler tab and drilled bolt were deemed useful in taxi cabs and cop cars or when perpetually driving in stop and go rush hour traffic where lots of low rpm/low oil pressure idle time tended to "dry out" the chain. Most of our driving of these cars today doesn't fit that description, thank goodness!
