I suffered a Run away diesel

I did the head gasket about 18 months ago and it went there then.
If you remember at the beginning the timing had slipped a tooth maybe two on the fuel pump. I don't think that would have caused it. I suppose the over reving would. No marks on the pistons from a valve hitting but that doesn't mean it didn't.
Hence why I'm going to strip the head completely and check all the valves aren't sticking out something else. Pointless putting it back without checking.
I think the bent exhaust push rod maybe could cause the smoke? Only one bent is the strange thing.
I will check the others but that one was obvious....lol
Push rods bend before the valves do. You should be fine.
If you are taking the valves out are you doing the stem seals?
