Hi All,

So I finally replaced the valve cover gasket along with the injectors seals that where leaking diesel onto the valve cover. I took it for a test drive and its smoking down from by the DPF, exactly the same as before, but as I never had any engine degreaser I didn't clean up the oil from before so I think (hope) it's just the residual oil, but how long should I expect it to continue for before taking another look just on the off chance there's another reason for it.

Here's a video of the valve cover removed and the oil residue from what appeared to have started from the back corner of the valve cover onto the manifold and further down.

And here's how it's smoking after replacing the valve cover
