Read with interest lots of posts on the dreaded CDi injector removal problems. I have just removed the rear-most (No. 6) injector due to blow-by of the sealing washer. Fortunately for me it could only have been blowing for 150 miles as I replaced a glow plug last Sunday and it definately wasn't blowing then so the gunk build up was minimal. It still took a lot of persuasion to remove and found that cleaning thoroughly around the base of the injector first then liberal soaking with diesel & WD40 did the trick to free it up so it could be rotated a bit at a time then lifted a bit, then pushed back in etc. etc. Anyways the copper washer is stuck at the bottom of the hole - any tips to remove? I have a good selection of large diameter drills and an air compressor to pressuris the cylinder but would need to accurately grind the correct angle on the drill or run the real risk of mucking up the sealing face if I drill down too far. This is to be avoided at all costs so would prefer something less invasive.
