Cam plate question?

No, either get the bolt with the drilled hole in the top passenger hole, or leave the bolt out all together... The timing chain gets its oil from that hole...

How to Assemble the Front of a Small Block
I just went and cracked another 318 apart and it's the same no hole in the bolt and 3 bolts with a slinger , that one I know it untouched it came outta a 79 van . That hole isn't under pressure it's just a drip hole . So I'm wondering if its plugged or must get oil from elsewhere. Like the 2 larger holes directly above them
