Last weekend while fiddling around with the egr pipe I noticed that the egr entry to the intake pipe was about 1/2 blocked. Not a problem in itself as the less egr the better! But thought I would take the intake pipe off for a look see and a clean.
It had maybe up to 5mm of gunk on the walls down stream of the egr, was not blocked nearly as badly as some of the later model inlet manifolds that I have seen on this forum, and possibly not enough to significantly effect performance.
The end of the inlet manifold that I could acces probably also had around 5mm of gunk. Perhaps not that surprising as the Paj has done 180k.
I cleaned the intake pipe (the dirtiest job I have ever done

These are my questions:
Is the inlet manifold likely to be badly gummed up to the extent that it is affecting performance?
Do I risk damaging the injectors by removing the injector pipes to get to the manifold?
Thanks for you input.
