[QUOTE="Tazza, post: 3597, member: 82"] That test will tell you if the plugs are burnt out or not, but unfortunatly they won't tell you if they are lazy or not. I had a set that tested just fine, BUT when i pulled them from the engine they were fat at the base and tapered to the end! I tested them on a battery and the base went red hot but the tip just stayed black. I was told they should start glowing from tip to base. You may have the same problem? The machine started with glows of 60+ seconds, anything less and it just puffed white smoke and it would splutter then stop. When warm, 1 flick of the key and it was away. The plugs just screw in, very simple. 3 out of the 4 plus are easy to get out, the last one is a total pig. Get a deep 12mm socket and you can easily get the 3 out. The one at the front i had to remove one of the injector lines to gain access to it. Ge hold of a 17mm flare nut spanner for this, getting in there with a standard spanner is really quite hard. You may even have to loosen the inlet manifold nuts to twist it to get the socket over the glow plug. Unfortunatly i dont have the part numbers of the plugs. I paid like $20 AUD for a set of 4, it made a HUGE difference in starting. [/QUOTE]
