Fresh carnage!

In reality, the bolt with the hole works OK. We’ve got a 273 with 300,000 miles on it and still runs better than most with 10,000 miles. Built in the 70’s with the bolt with the hole and a Direct Connection double roller timing chain. Car lived from FL to SD. And from the stories was never babied, cruised at 100 mph all day long, and has been up to 140 mph. The 273 is slated to come out this winter, but only to be replaced with either a 330 Desoto hemi or a 340. I am interested to take it apart and see just what the wear looks like after 45 years and 300,000 miles.

I get it works ok. So does no holes in any bolts. Or no drip tray.

Ok isn’t good enough when I have to stand behind it.

Drilling a hole in a bolt isn’t any harder than drilling a hole in the plate.

And it’s not just for gear drives or Chrysler stuff.

I put pressurized oil on Chevy’s too. Splash oiling or relying the oil mist in the engine doesn’t get enough oil where it needs to be.

Even though the cam gear turns half of crank speed there is still centrifugal force throwing oil off the gear and chain.

Where the oil hole in the plate is sprays oil on the backside of the gear and centrifugal force is forcing the oil between the gear and the chain.

And the fuel pump eccentric and pump arm will look better.

Guys are willing to drill a hole in a bolt but not in a plate. Makes zero sense to me.

Old school. I had original bolts with hole and bought a bunch back in the day. Just reporting facts. Never used a gear drive, built plenty of engines, probably not to your level but zero problems.

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.

Obviously you want to make up your own facts. You are wrong about the factory oiling. Is the .040 pressurized hole better, maybe, but not sure how you disregard 300,000 miles without failure and still running fine. Along with all the 340’s with over 100,000 miles with barely worn timing sets.

Yup. The bolt rules. Chrysler figured it out.

I’ll run with that.
