Down on the farm where I live/work, my boss has a series III lightweight Land Rover, which he plans to get back on the road after a number of years sat on one of the barns, but re-engining it with a slightly more modern 200 series 2.5tdi engine. Over the years the chassis has been patched and had parts replaced, but one of the reasons it has been laid up recently is due to chassis rot again, this time on the main chassis rail on the topside, under the floor panels.
There are at least two ways of gaining access to this area, removal of the rear body tub and, more simply, removal of the rear floor. Since we are not keen on making too much work for ourselves and the floor is corroding through in places, it was decided to lift the floor panel. This was done in an hour or so after drilling out all of the rivets and carefully prising the panel up. With this panel up the chassis can be cleaned up and decisions made on how much to repair it, just need to wait for some steel to be delivered before I start the welding.
Meanwhile, the GT6 has been receiving a bit of attention, with some of the smaller jobs being finished off and tidied up. The wiring under the dash is now, hopefully, complete having added a momentary switch for the screen wash pump and connected the inertia switch to the two fuel pump switches.
In the engine bay, the coolant header tank has been sited in what was the battery box, the two lower connections going through holes cut in the bulkhead support panel and the whole lot given extra support with a small bracket underneath the tank.

Polished rocker
Been doing a bit of maintenance for the saloon and preparation for the GT6 by servicing up a couple of sets of rockers for the six cylinder engines. A problem I had been having with the saloon was accurately setting the valve clearances; this was in part due to a slightly worn rocker shaft, but largely due to the worn faces of the rockers.
New rockers are available, but seeing as I had the time and inclination, I decided to service the ones I had. First off the shaft was stripped down and the components left to soak on paraffin for a couple of hours before being scrubbed clean using a wire brush on a drill and any oil ways cleaned through. The ware face was then carefully polished using WD40 on 600 grade glass paper, taking good are to alter the polishing angle as I went along, to maintain the radius on the face.
The rocker assembly was then re-assembled with copious amounts oil on a new rocker shaft.
Back on the saloon after the clearances were set, the valve train sounds a lot quieter now, so a successful job then, which was then proven with a trip over to Carmarthen to have a look at a MkI GT6, the new owner of which has also started a blog.
