So my 200tdi disco engine in the defender decided to die.
Basically the cam shaft had been pushed back into the engine and the pulley came loose wrecking the woodruff key.
Belt had slipped and 2 pushrods were bent..... All happened on tickover under no load.
Quick question.. Should the cam shaft move in and out?
I can pull it forward with the bolt in and the pulley/cog will stop it going back in when bolted on.
It turns easy enough by hand and seems smooth but but I'm concerned the horizontal movement shouldn't be there.. Anyone know? Thank you.
Pictures are with shaft back into engine. When it's pulled out it sits levelwith front of pulley.
 
if rollers will have dropped off the lobes you have to removed head and followers and vac pump,which requires the removal of oil filter head to reach its securing screw
 
I really hope that this possible useless bit of information doesn't lead you up the garden path because I'm quoting the camshaft end float data for a 300 TDi engine which is 0.1 to 0.2mm - the float is controlled by a thrust washer/plate which can wear. I don't know if this is true of Defenders but certainly on some of the older Renaults, excessive camshaft end float could lead to lack of brake servo as the drive for the vacuum pump was taken from a gear on the camshaft. The excessive float which was very rare, would allow the vacuum pump and camshaft drive to become disengaged. As I say this is probably a load of guff in your circumstance - but who knows?

Thanks for reply. Data makes sense. Going to explore inside engine on Saturday.....
