Thanks for the update!
I have a service due this week and will be attending to the inlet system too, although I don't have any major issues showing. I have new gaskets for the inlet pipe to EGR, EGR body etc. and I'll clean out the EGR, the inlet temp sensor (which is rather oily) and anything else I can get to in that area. Along with new oil, oil filter and fuel filter, I'll also do a quick check of the exhaust manifold with a USB inspection camera (making sure I have no cracks - yet).
*edit* I checked it and it IS cracked! -

All of which is required basic servicing needed on these old girls. A little TLC and they just keep giving.
