The morning after the engine was run Andrew found a telltale pool of red oil underneath the car. The inevitable questions: Where had it come from? Will we have to remove the engine and gearbox to fix it? Maybe it was coming from the speedo drive?, which was disconnected, and not blanked off. Monday night Andrew grovelled around underneath the car mopping up oil and trying to find out where the oil was coming from. It seemed to come from high up on the LHS of the gearbox. The strongest possibility was the reversing light switch.

I made another telephone call to Chris Masters at Westfield. Chris thought that it was probable. "There is a seal behind the switch". "Take the switch off and seal it with silicon sealer". said Chris. "The job can be done in situ", which was a relief. "It may be necessary to disconnect the gearbox mountings and push the gearbox to one side".

We had to wait until Thursday before we could attempt the job. We jacked the car up and put it on axle stands. Andrew found that he could get a hand up the side of the 'box. The switch is held in place by a couple of torx screws. Andrew had some short torx bits, courtesy of "Screwfix ", and we had a small ratchet socket in the tool kit. The combination was just right to enable Andrew to undo the screws. Once off, the seal showed signs of wear with and old sealant.

Friday, I went to "Gowerings" our local Ford dealer. By now, the guys in the parts department know me. They are interested in the project and the progress we are making. Fords computer does not show or identify the seal. I called Road & Race Transmissions, who refurbished the 'box. They gave the same advice as Westfield put the seal back and seal it with silicon sealer. They also said check the breather. "It is a trumpet like device on the top of the gearbox". he said. "I did not notice one when the gearbox was fitted". I said. They usually get knocked off when they take them out." was the reply….. I am concerned. He ends with, "It is a TRANSIT isn't it? Phew!!!!

Sunday we refitted the switch, now to see if we have cured the problem. We left the seal to cure for a few days whilst we worked on a permanent solution to the ECU / Tachometer output problem and we completed mounting the ECU. These jobs completed we were ready to start the engine again. All is well, we seem to have found and fixed the oil leak.
