I do not think it is listed anywhere but as it is M10 sized like the pulley bolt I uses the same value.

The terminals look like the ones used in Littel ATO 868 Series fuse holders. The terminal part no. is 09130900Z but it's listed as obsolete on the Littel website.

Could you shim the ball joint so it sits away from its usual mounting face to allow enough room to fit the washer? e.g. move the pod ball joints towards to outside of the car.

M10 x 1.5 No idea how I managed to type 10, that would be a bit coarse!

The likelihood of the exhaust manifold to head studs working loose is very low if you install them with the recommended Permabond A025 high temperature retainer adhesive. The exhaust manifold to head studs are M8 x 1.25 thread and the exhaust manifold studs for the turbo are M10 x 10 thread.

The 'remedy' is C-12 not S-12. The Opel documentation says to check fuse FV4 which supplies the power to pins 2 and 3 of the ABS ECU. The Lotus wiring diagram surprisingly does not show a fuse on the supply to pins 2 & 3.

It was the throttle plate stop screw that needed adjusting on Shaun's engine a few weeks ago to fix the idle problem. The butterflies were open too far at closed throttle resulting in the IAC valve being fully closed (IAC counts = 0) and thus preventing the desired idle RPM being reached. When the engine is at operating temperature, the ECU is in closed loop fuelling and all electrical accessories are off the IAC counts should be about 30 - 35 to give the desired idle RPM at closed throttle.

Travis, the catalogue is the Bosch 'Fuel Supply and Control' catalogue dated 2013 / 2014

Ian, you cannot rely on Freescan to show whether it's going lean under load because you will be in open loop fuelling and the narrowband lambda sensor is not able to give the ECU feedback on the A/F ratio. Looking through a Bosch fuel pump catalogue the highest BHP engine I could find the 0 580 453 477 pump listed for is rated at 220 bhp. I personally wouldn't be happy with that pump. Travis, I am dubious about what Lotus state is the fuel flow for the stock fuel pump but it's what they give and I cannot find a verified OEM part number for the pump to check it. Regarding the fitment of di

Are you sure the Bosch 0 580 453 477 is suitable? Bosch lists its flow rate as 105 l/hr at 3 bar. Lotus state the OE pump is capable of delivering 4 - 5 times the maximum fuel required at 3.8 bar.

The fuel pump relay is controlled by the ECU. The simplest way to see if the ECU is the problem is to remove the relay and jumper pins 30 to 87 together in the relay socket and the pump should run. If it doesn't then you need to investigate the fuse, inertia switch, pump and associated wiring. Your aftermarket immobiliser could be wired into the circuit too.

I do not know the grade or thread but the bolt for the later radius arm is M12 x 120 mm.

Sorry Brett, I was looking in the wrong section of the Service Notes and the two thermal valves I described are for the '87 onwards engines. Does your engine have a throttle jack and/or air pump with divertor valve?

There appears to be a shortage according to this article https://www.pulsetoday.co.uk/news/clinical-areas/immunology-and-vaccines/nhs-england-set-to-stand-down-multiple-mass-vaccination-centres-in-april/ I guess whether you consider this to be a shortage depends on your point of view; have the manufacturers delivered in accordance with their agreements or has the vaccination programme been too ambitious in the the numbers expected to be vaccinated by a certain date?

I doubt many people will distinguish between the government and an executive agency, especially as their staff are still civil servants. You will note I never said they have run out nationally. You seem determined to pick an argument and I guess the sarcasm in your various posts sums up your attitude to reasoned debate so I'm done with this thread.
