So I have ran into a problem...

I'm currently repairing a leaking head gasket on my Land Rover Discovery 2 TD5, most things have been going well; I checked the cylinder head for any warping and it is well within the tolerance, I have been deep cleaning the valve ports and the intake/exhaust manifolds. However, when I removed the glow plug connectors the rubber boots just disintergrated and in one case one of the connectors has completely broken off the wires. The wires are in good condition where they connected and it appears the connection just came off the ends.

Does anyone know what type of connection is used on the end? My research so far has led me to believe that female bullet connectors may be a suitable replacement, but I wanted to double check to be certain.

Any advice would be greatly appreciated. I am intending to remove, clean and then re-wrap the entire harness with cloth tape and braided wiring sleeve as the original plastic stuff has just disintegrated in alot of places.

I believe the part number for the harness is ERR6066. Not sure about fixing the plugs. Seems like it could be ok, but the TD5 ECU is a little, err, sensitive... Personally, I'd have a go.

My nephew recently had the same issue. Doing HG and found all glow plug wires failed or close to it.

He and his dad just repaired each wire as required. That is, the failed connectors were soldered onto the wire, any dodgy looking wire got a sheath of heatshrink.

I saw online(maybe youtube??) someone used a VW glow plug loom. The spacing is close to identical. I tried to find the video for nephew to see it too, but for the life of me can't find it.

ERR6066 should be available from UK I was able to fix mine with heat shrink. Regards PhilipAhttps://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTgI7ttRN_1bFAPVNRZ3z6FxDlhwe1GZ oMKJESkML68FZ3qzUmP_Jn_-Rs&s

ERR6066 is the glow plug's p/n, there are many glow plug harness repair connectors available, they are quite common and the same for a huge variety of engines, for the Td5 is good a connector which works for any of the vehicles shown in the compatibility list here Just a moment...

This is not really helpful in regards to repairing your problem, but, I don't think the glow plugs worked in our old 01 D2 for the entire time we owned it. Our mechanic at the time said, I can fixed them, but you don't really need to unless it becomes hard to start, which never happened.
