Well its been quiet on here for a little while now but there's been lots going on in the background. The car has been and still is in with Iain at Passion Engineering who has been working his magic on bringing the car up to spec, I'm still keeping my fingers crossed for the LMC next week. It's safe to say if everything falls into place then it will be one hell of a road test!
The car has been significantly stripped down to accommodate all of the work, the engine was opened up to check tolerances and make some adjustments when it was noted there was some slack in the timing chain when rotated backwards so it was decided to install a new kit. The broken water pump bolt has been resolved and new carbs installed and adjusted ready for tuning. The new radiator, coolant system filter, rocker cover and hardware will be following shortly. The steering rack lower UJ has been replaced which I'm keeping my fingers crossed will eliminate the play that was previously in the steering to really sharpen up the response with the newly fitted adjustable suspension.

The bulk of the work has been transmission related with several surprises rearing their heads yesterday giving me a bit of a shock and stark reminder of the cars age and unknown history. Below you will see what remains of the clutch pivot pin and the nice 'round' hole that it was located in. Safe to say that was an utter disaster waiting to happen and could have been a mess had we lost the clutch in France or anywhere else for that matter. I've been oblivious to the pending disaster all of this time. I've never been happy with the clutch but assumed it was a worn release bearing causing my trepidation. Fortunately Iain is fabricating a new pivot pin and has completely fixed the mounting hole so it looks factory fresh. His fabrication skills never cease to amaze me and remind me why I don't attempt the bigger jobs at home on the driveway...

Moving onto the gearbox mount itself we were surprised to find it looked nothing like we expected given the age of the car and after some investigation and confirmation from Richie appears to be an automatic transmission gearbox mount. Looking further into it there are no manual mounting points so I'm assuming that the car was more than likely an automatic from the factory that was converted in the US during its lifetime? This being the case I wonder whether the pedal box has also been swapped to accommodate the clutch and center console non original due to the auto transmission shifter? I'd love to hear from the Z aficionados who will likely be able to advise. I believe we are now proceeding with a full custom mount to suit purpose.

There's even silly little things like the new clutch master cylinder rod being too short for unknown reasons causing more work!

I can't praise Iain enough at this point for the time he is putting into getting the car finished and most importantly to the very high standards which he works to. I really shouldn't be shocked by some of the things that rear their heads now given all that we've found in the last couple of years but it still does shock me. This is a car with a past that I do not fully understand and would love to know more about. I'm at least now thinking that the car had the gearbox replaced as well as the engine which really makes me want to check the rear diff ratio as well.
It's safe to say it should drive impeccably well when finished, the car will have had all of the suspension, power train and drive train overhauled with very few exceptions. It will be far from the spec that it left Japan with back in September 1970 when it rolled off of the production line.
Hopefully more and positive news to follow very shortly
