I think that you'll find that only electrical faults will give rise to fault codes, not physical faults. It's quite a big job to remove injectors, i.e. camshaft, cam belt out etc but it will give you the opportunity to replace some well-worn camshaft shells (particularly the upper ones)!

Yes, because of the upward pressure on the cam from the injectors. Even if you use all the correct oils and at the correct service intervals!

@RAB those shells are big b****rs, never seen them so big before. If I have to replace injectors it will be interesting to see how large and worn they are.
Today's progress, if nothing else I will have fixed a long standing oil leak. I bodged it several years ago with engine silicone:
New harness fitted:
Oil leak cleaned up:

Will do, that is the reason the EGR valve is off (perhaps not caught in the pictures). That way I can get a torque wrench over the rear screws.

This is the manual page I am talking about for sealant and torque proceedure...

Been really unlucky Albert has just finished his days as my daily. Two of the cam cover screws stripped out before 10Nm clicked on the wrench.
Even worse it is two of the rear ones so I can't see any way of coiling them without taking the head off. I'm going to nip it all up so that I can get him into storage until I have time to tackle the head.

I can re-thread it but I need the head off first. They will need drilling out and at least 2D coiling. I'll probably do them all.
It is definitely the female threads, a tap just collects the stripped threads and rattles around in there. I assume the problem was fatigue?

It wasn't me; mixed up Nm and lbf ft in the past, not this time:

At least it will give you the opportunity to change the camshaft shells!

I've cleaned the inlet manifold and EGR valve, they were dirty rather than restricted. Otherwise I have only replaced the injector harness. This is cold start idling; It sounds better than it did so ? for smooth reliable running on the road.

So, to sum up, the new injector loom sorted the rough running?

I think I see what I’m looking at. It has worn through two coatings and is wearing out the white metal? Still very smooth though.
