No, not the newsreader, the force which inexorably sucks little bits of engine down and behind other bits of engine in impossible-to-get-at places while you're busy spannering. Grr.
Plagued by ping-fuckits too. That'll teach me to be greedy and try and replace all 4 glowplugs - should have left the last one alone rather than taking bits off to gain access. Still, I appear to have won for now. The winning move seems to have been to have started browsing autotrader for a replacement - obviously the car noticed, and decided to start playing nice again rather than be sent to the heap.
