Cam sprocket bearing oiling question.

[69427]

I've got things mocked up with the block protector roller bearing between the block and the cam sprocket. I've never run one before, so I don't know their durability. I'd sure like to put a bit of oil in there to help things out, but I'm not sure I can get a decent stream of oil there. I was kicking around drilling a small hole in one of the galley plugs, but half the time the oil would just spray through the sprocket slots, and I wonder if the rest of the time the oil would just be flung off the back of the sprocket instead of making its way to the bearing. I tried to see if I could drill the hole at an angle, but as small as these plugs are the angle stays pretty narrow. So, any thoughts?

Drill a hole in the machined face of the cam bore, not in the plug. That will give you oil where you want it. Those torrington rollers don't need a lot of oil but if it were me I'd use a brass thrust washer setup, I don't trust those rollers...if they fail you have a lot of shrapnel floating around.

Do you even need a thrust washer? It was my understanding that the cam sproket to block surface was adequately protected by the oil flowing over it from the lifter valley drains and spray from the chain.

He has an aluminum block so it's more a block saver. With that block I would certainly not run without some sort of scuff plate.

I always drill a #60 hole in the left galley plug. That way the oil catches it going up, and flings it down and around too. It will spray everywhere.
OR:
You can buy the galley plug predrilled from GMP for $10.00. LOL

Some blocks are what we call "Front Walkers", while others are "Back Walkers". Even on iron blocks, it's best to do what's needed to control movement in both directions.
