Thanks for the update Jeff. Most of the wheel bolts had a good covering of copper grease on their threads and tapers. I'm in favour of doing that. Liberal use could affect torque ratings. Apart from that one wheel's very tight bolts, the three others felt about right undoing them using my hand tools including the heavyweight 3/4" Breaker bar..
I was able to successfully remove all four McGuard style Locking Wheel Bolts but, due to tightness and some abuse of the Locking Key, a five minute job took an hour of careful work. They were tight. These were discarded and a different set fitted along with the refurbished Hairpin style alloy wheels.
Progress is slow in these cold weather conditions. Some sunshine as I write this is encouraging. The hard frost late last night was gone by daylight from the slighter milder breeze which sprung up overnight. Might get a an hour on the car today after other chores.
Chores included stripping my relatively little used Rockworth 240v electric drill which expired in a shower of sparks out of the cooling slots last time I used it. One of the carbon brushes has completely worn away. Web search turned up a carbon brush specialist on ebay who will fit new carbon inserts to the old housings as brushes for this model are no longer available. Be good to revive that drill as it has a hammer action facility which is useful.
Next job on the ZT-T is to reassemble the in-tank fuel filter after checking if an Orange Clip is fitted. I have a clip on standby if it does not. Jeff removed it to access and remove fuel in the tank as he was thinking of disposing of the car. Most folks including myself would do the same.
The first "project" ZT I bought had a near full tank of fuel. Along with suspect head gasket, the engine was a non-starter. Needed open and refit the in tank fuel filter after slot the Orange Clip in place. Immediate start which soon confirmed damage head gasket. Not an easy job with fuel brimming the tank. Must have used five pairs of gloves for that job..
I need to make up a couple of small blanking plates from some stout alloy sheet I have. There are a couple of places on the MG6 engine where features will not be used and need to be blanked off. Speaking to one of my son's friends who works for MG up at Longbridge, he told me the Chinese had destroyed all the original low pressure engine casting stuff and manufactured new ones designed for high pressure casting. Looking at some areas of the MG6 engine, you can clearly see many differences owing to new castings being tooled up.
I shall shop around for a new clutch release bearing assembly as several folks advised doing this with the engine and gearbox seperated. Good advice on a stitch in time basis.
