is all ok at the top end rockers all set up right, all moving ok when you manually rotate the engine.
ive seen them run, but badly, like this with a broken cam.

I haven't actually removed the cam yet. That will be my next job! I have just striped the injectors as they were leaking. Cleaned up and reassembled. Re-clocked the fuel pump and still hard to start. White smoke and hard to rev. Oh checked egr also and all free moving.

I noticed on your Vid that No1 injector was blowing. I would advise you to get a experienced Diesel Mechanic to have a look and listen to your engine, it will probably be more cost effective in the long run rather than guessing and fitting unrequired expensive parts.
Good Luck.

Yes it was.that's why I'm striped them today and sorted all leaks now. One last hit tomorrow where I'm going to take the head off to look for damage.of there is none then none then the engine is getting dropped!

I feel that you are using this vehicle as a learning project(Hobby) It is a very expensive learning curve "hobby" but a lot of hobbies are.
Its your Money.

I have rebuilt many engines and done smoke jobs on diesels like head gaskets and other repairs but I'm not a diesel engineer. There is no one near me that i would trust though. All garages around here rip people off. This cane to me after a garage had fitted a new head!

I'm leaning towards either valve damage or small end/big end rattle.
