I have worked on this motor on and off for a couple of months now...I think I am closer to knowing that is stopping it working..I think it is the injector seals...seal no 3 is showing signs of blowby.

I have renewed all the seals again, bled the system, engine floods and locks up...and I get no further. Am very close to the end of my tether on this now...so need outside help.

So - does anybody know of a reliable, knowledgeable local (SE Kent) mechanic who is good with TD5's.

I know you said you have checked it but I still think your cam timing is out. Diesels as we all know work on the compression of the diesel fluid to make them fire. Did you have the engine at TDC NO 1 cylinder and the camshaft sprocket in the correct position when you replaced the timing chain?

Diesels compress air only-when the air is hot and compressed the fuel is pushed in at even higher pressure to start the burn-hence the silly pressures from injection pumps compared to Petrol engines
They do not inject and then compress.

Southcoast garages are good, worth giving them a call. Sorted my Disco for me. Very knowledgeable.

Somewhat pedantic post.

Does'nt change my opinion on his problem.

merely pointing out the inaccuracy of your statement in case others were to believe it and thought that a diesel engine ran that way-yup doesn't help the op at all

Hi there, the timing is spot on and the mark on the pulley lines up exactly between the two coloured links on the chain. I did not remove the timing chain. So that allowed me to insert the two timing pins, one top and one bottom.

Noted, and thank you for your input.
