Looking at My Bro's recently aquired 1.9d 6n, I can see that the front grills do let an awful lot of air in- def worth bringing the grillblock back!
on an aside- any hints or tips re the Glowplugs? got 1 and 2 done- but fingers too fat to get into 3 and 4- and I dont want to have to take fuel system or throttle system off...
Much appreciated
