I think this is broken.

This vehicle has come in to the workshop because it was knocking badly.

The engine has come out and this is what I found warning these pics aren't pretty.



That's the contents of the oil sump after the oil was drained out there is a lot of swarthe there and what appear to be needle rollers. One big end has 2mm of play. but that doesn't explain the rollers so further investigation required.



So off with the cam cover which revealed this. One of the cam followers has disintergrated to the point that its not even there any more. All that is left are chunks of finally ground metal all over the head and likely blocking all the oil ways. The damage to the rocker is severe enough that the valve it operates would not have been opening.



After removing the rocker shaft and seeing the damage to that I expected the cam shaft to be truly destroyed but it isn't. Its not serviceable certainly as there is a chunk of the lobe missing and the lobe is deeply scored, that just shows how hard a cam lobe really is.

I'm in too minds weather its worth attempting to rebuild this engine or not. The head is certainly going to need major work, the crank will need to be reground and the con rods replaced and I haven't even got to the bores yet.
