Engine sensors fitted

So the instruments have arrived. Now I needed to fit the engine sensors.

First was the oil pressure sensor. Not straight forward! I had to loosen the plenum first so that the sensor would fit. Without this being removed the sensor was too wide at the base. The sensor is fitted in to the M16 to 1/8" NPT adapter. I had to tighten the adapter to the sensor first, before I used grips to gently tighten the sensor in the hole. The wire to the loom was then attached.

Next came the water temperature sensor. This is fitted to the back of the off side head and there is little space! The back spark plug connection was removed to give a little more space. The adapter was again fitted to the sensor, before tightening in the head. Finally the loom wire was attached.

Finally the oil temperature sensor was fitted. For a change this was easy. Accessing the oil filter housing from under the car, the adapter - pre-fitted to the sensor, was screwed in place then tightened and the loom wire attached. NOTE: Do make sure that the sensors are tightened - I hadn't!

Now, whilst in the engine compartment I did a couple of small jobs. First, I am embarrassed to say, was to swap the rocker covers around. I had re-fitted them on the wrong sides. D'oh! Not that it matters that much, but I had decided that it would be easier to fill with oil if the filler was on the off-side. This required the coils and plug lead assembly to be removed from the covers and re-fitted to the correct cover. The fitting of the vacuum pipe had to be modified slightly too.

Next came the washer bottle connection. The water tube was fed through the lower hole in the bulkhead (after fitting a grommet) and connected to the outlet on the washer pump. The two wires were also fed through the hole and connected to the pump.

Just to fill in the time I set up the dash with the steering wheel to check if I could see all the warning lights and gauges - I couldn't, so have moved a few things round. So here is how it looks at present. The GRP panel will need some fettling to avoid the hinges binding and to closely follow the scuttle contour, whilst allowing for the leather trim.
