200tdi cut out and will not restart

@dag019 if you remove the rocker gear from the head then turn the engine with the starter motor and you find the engine turns hard and evenly, (even compression with no "chuffing" from exhaust or inlet manifolds) then that would indicate the valve timing was out due to the "shock shearing" of the camshaft sprocket key.
If "chuffing" persists with rockers removed you will have a bent valve or more to deal with.
Turning the engine over with no rocker gear means you will have two cylinders compressing every half a revolution of the crank so don't work the starter like this for too long, just long enough to detect if a valve or two is leaking past. After seeing you photo of 8 bent pushrods I imagine that the cam key had a bit of stress applied.
Good luck.

What do you mean the cam key? Are you suggesting the cam timing cog has slipped on the shaft? I will check that in the morning.
I will also check the valves and redo the timing again as see if that makes a differance. I agree is sounds like a valve is positively open which is what lead me to think the timing was still out.

Did this and I still get chuffing (same as previous video) out the intake manifold so I am assuming I will need to take the head off to investigate. It does not appear to be a bent valve as all of the valves are level when a straight edge is applied. I am guessing once the head is removed it should be more obvious what the problem is?

Thank you @jamesmartin for the cam sprocket torque, I will still check the keyway when I get a chance.

As I now know that the intake valves are leaking do I need to purchase a compression tester and carry out a test before pulling the head or should it be nice and obvious what the problem is once it is removed?

id just pull head off and take plenty of pics and drain the block before by removing the brass drain on the lhs of block

Not taken the head off before. What do you mean by drain the block? What am I draining, I will see if I can find the brass drain when it is light tomorrow. And hopefully get the head off in the evening.

Before you pull the head off, have you as yet made the time to confirm if the cam sprocket is still in time with the camshaft?
Remove the retaining bolt and check if the woodruff key is still in line with the keyways.

I haven’t done that yet. I will do it tomorrow as well as removing the head. I have checked the the valves are the problem by removing the rocker shaft and “starting” the engine and still get “chuffing” out of the intake manifold despite all valves being closed.
 
I've never had any luck getting that drain plug out on 3 engines I've reconned. It's never been much of a biggy though.

One of the write ups I have read on how to do it didn't mention the drain plug and just removed the lower hose form the water pump. I will try the drain plug but it is good to know if it doesn't come out it is not the end of the world.

I am not going to remove the exhaust manifold I am just going to unbolt it and move it out of the way, I know this is possible because I have replaced the manifold gasket recently without removing it.

Do I need to remove the glow plugs and injectors? It looks like some do and some don't. I will need to buy the required tools first if I need to remove the injectors.

Finally, is it worth rebuilding (after checking the cam sprocket, and assuming it is fine) the timing belt/cover/front end, before removing the head. This way I have less to risk going missing and there is no connection between the two jobs?
