It has nothing to do with gear drives. I’ve seen more junk timing chains from lack of oil than anything else.
I know you want to defend Chrysler for doing stupid **** and you like feel good solutions but I don’t have that desire.
Chrysler only cares about getting through warranty so they did dumb **** like a bolt with a hole in it.
I mean how much oil do you think gravity feeds through that hole?
And what happens to the oil that does DRIBBLE out of it?
That’s right, it slobbers down the front of the block and end ms up back in the pan.
I’m done trying to convince people that slobber oiling the timing set doesn’t do ****.
A tomato can grasp the difference.
