I've fitted a blanking plate (not really 'blanking' as it is the one with a 10mm hole in it) to my 2009 Focus 1.8 TDCI.
I can't say I've noticed any effects - good or bad but I'm a bit nervous about it. Am I in the long term doing more bad than good for the engine?
What has been your experience? Have you fitted this plate and if so have there been any bad effects and if so what were they and after what mileage?
I get nervous when I read this: http://www.wynnoil.c...atured-egr3.htm
Is there any good guide, with photos, on cleaning the manifold and egr on this car. The plate is fitted at the point where the pipe from the cooler attaches to the inlet manifold/EGR system (see attached photo). Would there be any merit in spraying EGR cleaner in here and letting it have a good soak occassionally? Does this get at the part of the valve that sticks?
