Changing Glow Plugs

I have to r&r the glow plugs, I think there shot. Is changeing the Glow plugs a simple job? Do I just take the valve covers off and simply remove the glow plugs and put the covers back on , or is there more to the job than that? Anyone have a pic of the heads with the valve cover off? How many hours would you think it would take to r&r 8 plugs?

Thanks Jaaaaaaaack

Thanks Plowhand ,that thread makes it seem easy. I guess the worst that can happen is a glow plug get stuck snd snap off in the head. When I do this job I will snap some pics with my new digi camera, I do not know how to post pics but if someone is intrested I will e mail the pics and they can post them for the benifit for others.

Before you get into the valve covers I'd check out the easy stuff first, it might be as simple as cleaning the four connections on the gpr. I jumped he gun and replaced them and still no cold starts. Ended up just needing to remove each of the connections and sanding them to remove some surface corrosion. The glowplug replacement took me about 4 for both sides (a couple of bolts are a real pain) and a lot of skinned knuckles also a fair amount of cussin.

I hear ya Bridgeman, no since over looking the small stuff. I just took out the batterys and will take them over to AutoZone for load testing, got my fingers crossed that maybe the batterys are just getting old, there dated August 2000 so maybe thats the problem. I will also scrub the gpr terminels like you suggested.

Thanks Jack

Hey Jaaaaaaackman,
Don't do what I did if you happen to snap one of the glow plugs off. I had one that would not come out and ended up leaving it in the head and put the VC back on and ran the engine. Well, it came out. Right through the VC and stuck into the insulation on the hood. Scared the snot out of me. I thought it dropped down inside and maybe punched a hole in the piston or got stuck in the valve port cause it was misfiring. I was actually relieved to see the hole in the VC. When you do the job check the wiring harnesses under the VC and the VC gaskets. When the glow plugs fail they sometimes melt the harness conns due to high restistance and heat. Good luck.
