sweet! did you ream out the bores?

i guess strategy of replacing only a few makes sense being that you didnt have to remove intake. Might as well save some $ for other stuff

I need an SDL !

I found it a pain to do my 5 cyl without removing the hard metal injection lines.
I also decided to change all 5 at once.Bosh and beru are good plugs.
stay away from champion and autolite plugs or you will be doing the job again soon.

I have been reading your posts on this topic. As I bought this model about 4 months ago and its my first diesel I have no tools as yet and I need to change my GPs as 5 of 6 are bad (ohms test). what size wrenchs do I need to remove intake manifold and GPs and wire nuts? not ready to buy a full box of tools yet. have 1/4 & 3/8 drive ratchet set for US sockets.
thanks for any help and any links to how-to wit pics
suprised it still runs (when temp is over 40f) with 1 GP good?

If you're going to replace only #5 and #6, I suggest you leave the intake manifold in place and instead remove the cruise control actuator for access. I don't remember all the tools involved but you'll need a 5mm hex bit for the cruise actuator and a flathead screwdriver to pry off the ball-and-socket linkages.

edit - Oops, I read that as #5 and #6 are bad. For the manifold, get long ball tip hex bits. The intake manifold bolts take a 6mm bit but you'll need 5mm for the job and 8mm, 10mm and short 12mm elsewhere in the engine. Note how many fuel injector line clips need replacement.
