The original oil catch tank was mounted to the engine with a single welded bracket started to crack so I removed it just prior to the Le Mans trip last year. Based on post on the WSCC Forum and Burton Power I decided to fit the new tank to the scuttle. I fabricated a suitable bracket that bolted to the aluminium panel and the front of the scuttle so it so be pretty robust and not suffer from fatigue. I them made the connections using silicone hose that is fluoro lined to prevent oil seeping through.
In order to fit the alternator I first removed the throttle bodies to gain better access, I also took the opportunity to check the oil temperature sensor and tighten it further. The Denso alternator is a completely different shape to the original one and my plan was to make a completely new set of mounts, however, after playing I eventually worked out a way of reusing the Westfield bracket with a series of shims and a new upper adjustable mount originally designed for a Crossflow.
The electrical connection need two additional wires, one to the ignition switch and one to the battery both connected to the alternator by a 3 pin connector that also had the dash warning light wire (I connected this even though the DigiDash2 doesn't use it just in case I ever want to go back to analogue instruments. Before fitting the TBs I installed a thermal block gasket that I'd bought a couple of months back to try and reduce the heat transfer from the head to the IAT sensor. Once everything was reinstalled the alternator was producing 14.1 V at idle with the DRLs on and dropped to 12.7 V when I switched on the heated windscreen, headlights and heater so it looks like the 40A output is enough.
Finally I bought a silvertop cam cover and sprayed it with orange high temp calliper paint before fitting it. How just need Aerodynamix to reopen for business so I can get a carbon fibre cover made. Tricia took some convincing that it needed baking, but I agreed to clean the oven afterwards - it need it anyway! I bought a new cam cover gasket set that included the 10x gromments for the mounting inserts before I fitted it.
