      no there was the normal amount of oil in it when i banged a hole in it. i realized there was no oil then mext day when i started driving down the hill and my oil light popped on. turned right around back home and turned her off till i got the pan welded.

      any advice on what my options are? ( look at my last posts)

            have you been pushing pushing it to 7100 alot and for a long period of time?
            i only ask because if the head wasnt getting oil up to the bearing and it spun then it would be messed up and get worse from that point on. And an M42 has cam carriers you can try replacing along with that cam and see what happens.

                I would still pull that bottom oil pan and check for metal chunks. This is very typical of M42s. The metal chunks could also be from the chain or guides deteriorating. They could be blocking the oil pump pickup.

                I think it's more likely that you killed it from no oil pressure. You said you saw the light and you turned around and went home. It only takes a little bit of no oil pressure to foul things up.

No oil pressure in the motor. Or a clogged port to the front journal. The fronts always wear out first cause they have the timing chain ripping down on them. Make sure you have oil pressure or it will happen to the new head.
                  what overhead cam head have you ever seen with actual "bearings" like a crank? I don't think even old school pushrod motors have that.

                      so would pulling the oil pan off to check solve anything? i mean, sure i might find some metal chunks, but doesnt it mean its already been sucked up into the head and clogged up there? or are you saying its jammed right in the tube that dips into the oilpan....

                        none overhead cam but pretty much every car that doesnt have an overhead cam has bearings you hammer out. Seems a lot cheeper then changing the entire block. The cam cradle is a good compromise though. I was unaware the m42 had one

                          I think you might have screwed up the cam when you ran out of oil. It can happen that fast

                                Yep, you do not want to go through the trouble of replacing the cam carrier and cam and putting all back together only to find out that you have low flow from the pickup tube being clogged. It is cheap insurance. I've lost count of the people who have toasted their engine because of the oil pan bolts had come undone, too. Check out M42club to see more. Either way I would thoroughly clean whatever you can reach. The pickup tube can be pulled out and cleaned, too.
