This is what a cam failure looks like

This is what a 3.5/3.9/4.0/4.6L cam/lifter failure (my '96 D1, actually) looks like..... :x
This damage occurred shortly after doing head gaskets and installing new lifters and oil pump. I had cleaned everything and I thought I'd flushed it all enough. I primed it, but maybe some crud in a passage blocked the oil feed for a bit on startup. Doesn't take much to do damage. Block and oil pump look good, all the oil passages are now triple flushed and clear, pan and sump removed and cleaned. One lifter bore is scored a bit so I still have to hone it. Needless to say, new cam and lifters are on order.
I would say "Bloody Land Rovers", except this is likely my fault for not taking enough care on the clean and prime. :roll:
This is the 3rd LR 3.5/3.9/4.0/4.6L motor I've redone, but the first that I really screwed up. Lesson learned.
