My current plan if oil does not make it to the cam journal is to press the bearing in and cross my fingers that the oil holes align. If they don't align then I will have to press the bearing out (towards the cam) enough to verify where the oil hole is on the block, align a new bearing and press it in until the holes align, then cut the dangling old bearing off the cam with a Dremel tool cut off wheel. I'm just hoping that the remaining three cam bearings have their oil holes aligned properly...
