Re: gearbox soundproofing
In my case I was able to reuse the original piece of foam but given the amount of oil it was impregnated with I very much doubt it would much difference if it was fire retardant foam or not. If your proposed piece of foam has come from a sofa meeting current regulations, would it not be fire retarda...

Re: Insurance and old cars
I've been in a similar situation myself so I have some understanding and appreciate the rules over taxation and insurance have some perversities but why didn't you just declare SORN??? Given we don't have to pay any road tax for a classic car it's easy to switch between taxed and SORN at the click o...

Re: Headlamp scoops series 2
As they left the factory, no, no sealant but in today's world in the fight against corrosion you'd be mad not to refit the scoops without a thin layer of sealant to keep moisture out of the inevitable mismatches between the scoops and bonnet.

Re: Sports exhaust
There's definitely wadding inside, can't recall over baffles, so you're left with more than just a straight through pipe would be. Somewhere I've seen a drawing/image of the standard centre box cut open but can't find it.

Re: Sports exhaust
I have the same arrangement as RFS1957 describes above created by taking the standard mild steel system bought from Jaguar and then drilling out the two baffles. Sound is as he describes and for me is the perfect balance given the standard system with the baffles left in the centre boxes is just too...

Re: Otter switch earth?
Yes, but that's not the point. Allrand said the header tank had to be earthed because it is rubber mounted and that is simply not true.

Re: Otter switch earth?
Yes but the header tank itself needs to be earthed because, as the OP mentioned, it's rubber mounted. No, Andrew is correct, the header tank doesn't need to be earthed, it's the body of the Otter switch that needs be earthed and it's connected to earth by the lucar under the bolt head as shown in t...

Re: Thinner than usual valve pads
You certainly can shorten the valve stems by a certain amount - when I had a late large valve head rebuilt recently, they removed the same amount from the end of the valve stem to equal the amount the valve face lapping had moved the valve up by to save finding new shims - but I doubt you could shav...

Re: Voltage across coil terminals
Steve, this is just not correct. If you measure a voltage without any current flowing you will get zero voltage drop and hence it's pointless. If you do what the other Steve has suggested and disconnect the wire at the coil +ve and measure the voltage what you're actually doing is measuring the volt...

Re: Voltage across coil terminals
Once you disconnect the wire to the coil +ve all voltage measurements are meaningless because you've broken the circuit and no current can flow. It's not the normal operating condition. It's why Tom added his caveat in post #5 because you need the points closed for current to flow.

Re: Voltage across coil terminals
No, Steve's test tells you nothing except that you've got continuity between the coil +ve terminal and the battery +ve terminal - and you knew that already because the car starts and runs. There's a long length of wire with several connectors in it between the coli +ve terminal and the battery +ve w...

Re: Voltage across coil terminals
It may be fine but I'd also measure from the coil negative to ground and from coil positive to battery positive to understand where the nearly 2 volts is going.
Once you know where and how much all the voltage drops are in the circuit can you make a better judgement on what's alright and what isn't.

Re: 2+2 windscreen seals
Based on my experience, you need both. The main seal comes (from COH Baines) to a set length with the ends welded/glued together which is what you need to prevent leaks. The second seal is the locking strip which is sold by the meter. Here you need to make sure you have enough because you want your ...

Re: Washer jet replacement..
Use jets from a 2+2 that have two jets each. Use silicon rather than PVC washer hose. Find someone with small hands to help. Connect the hose to the jet and feed the hose in from outside the car. Slide the nut back up along the hose from the inside so the hose guides the nut onto the end of the jet....

Re: SU fuel pump circuit breaker spark
Varistor or capacitor, both will do a similar job in this application. If you were to use a large non polarised capacitor such as those across the input to a power supply your pump would remain polarity insensitive. A capacitor would be a better choice for suppressing RF radiation so would be my cho...

Re: Cylinder Head Woes
That story has been around for a few years now. Whilst there are undoubtably fakes around I'm more dubious that the major suppliers have been taken in, in any significant way. There are videos out there comparing fakes with originals and in the ones I've seen the fakes are pretty obvious with errors...
