oil pressure and adjustable hydraulic valve adjustment
If I did wipe a cam lobe. Does the engine need a complete tear down and rebuild. (i.e. new cam, rod and main bearings and de-glaze cylinders?
yes. not "complete" that makes it sound like more than it really is.
bearings are cheap, and if you do it now you are much safer. main and rod bearings are probably still ok. chances are they were getting enough lubrication, but could just be replaced at this point, that's up to you.
cam bearings will take some work to replace. cylinders & rings are probably fine & dont need to be touched. but like moper (dave) said you should pull the intake and inspect what you can.
however, if you continue running it, without digging deeper, then you could be in for a lot more work.
if you wiped a lobe that metal had to go some place...
what work you have now is not too bad... consider that some racers pull their engines down after every week of racing :D
right now the big thing to worry about is the cam bearings and whether the cam lobe is gone. it could just be a bad lifter on that one valve.
