replaced all 5 glow plugs. was able to get the first 3 in without removing injector lines. last 2 no way .. removed the lines and it was still kinda tough to get in there but managed it. total time 2.5 hrs.
the old ones were heavily carboned up, and a couple had pitted tips.
replaced them all due to they were 9 years old, and had some cold start problems.
for info the glow plugs are 12mm and the little nuts that attach the wires to the plugs are 8mm. injector lines are 17mm.
if i had the job to do over i would have removed all the injector lines first.
