I need the length and diameter of the tommy bar that fits the J7 tool.

If you have one I'd be grateful if you could measure it for me.

1. Buy one of these. https://i.postimg.cc/cLdLz1DM/camber-gauge.jpg 2. Using a piece of aluminium angle and a couple of fully threaded 15cm bolts with nuts, make a bracket to allow you to position the gauge accurately on the wheel. The bolt ends go in the groove for the wheel weights. Obviously make...

See below.

The obvious advantage of going to triple Webers rather than triple SUs is that it costs about half as much for a set. The downside is that you will need to find someone who is very experienced in setting them up. This is a complex process, requires a quality dyno and someone with a large selection o...

Yes Peter I can do this of course. But I don't like the "nearly right". I suspect that your distributor drive is incorrectly aligned. This usually happens when on assembly you fail to turn back the drive cog 3 teeth to allow for rotation of the distributor drive shaft as the crank drive cog is tapp...

Cheers Terry...
I have just ordered some additional springs, Not a job for this weekend though as I want to get out in it.

Can you use one of your old springs? Haven't done this for a long time but I do remember it being a difficult job.

Andrew, stop the pump and disconnect a pipe, you will get a flow because of remaining pressure in the circuit. Once the pressure is zero flow will stop, precisely the well respected Poiseuille equation. Only if there is elastance in the circuit, because the liquid is incomprehensible. I suppose the...

Can you fit a 6th spring in?

Of course, with all due respect to the wiser community, I stand to be corrected.

From the Hagen Poiseuille equation, flow is proportional to the pressure differential.

If the pump is stopped there is no flow, and therefore no pressure.

I was not aware that it was possible to modify original front calipers to take larger pistons or wider discs. It may be that what you have at the front currently is not actually original but one of a number of upgrades. A photo of what you have would make that clearer. If you have original S1 front ...

Before the car went away the bonnet would stay up once opened on its own.

I'd be asking then to fix it.

Don‘t the spinners say „offside“ or „passenger side“ or something like that ? Interesting when your car is an LHD....

It's to confuse the Hun.

.i think the easiest way will be to swop the hub/carrier with the drive shaft from one side to the other. Brilliant idea. Take care when removing the outer fulcrum shaft that you don't disturb any shims that might be in there to provide the bearing endfloat. Easiest way to do this is to make up a d...

As Christopher says to improve flow.

I've certainly seen this recommended and done in 6 cylinder oil pumps but I have no experience with V12 ones. I doubt it has done any harm.

What I'd really like to see is a couple of shots of the cover that holds the switch in place.

Just use a sharp cold chisel and a hammer and go gently.

The Jaguar manual says clearances of 4/6 thou for the 420G, but I think that the P31818A cam is the C35556 cam for the S2 E type and also used in the XJ6. So your cams have either been changed at some stage or Jaguar fitted the quieter cams to later 420s.

If you replaced the fuel filter you may well have an air lock. Remove the fuel pipe where it goes to the carb fuel rail and turn the ignition on until you have fuel coming out of the pipe (into a container). Reconnect the pipe. If it still doesn't start check all 3 of your float bowl jets to ensure ...

Are you sure that the "oscillations" you are seeing aren't normal? With the caveat that I don't know anything about how combustion and valve timing affects measured AFR in exhaust gases, I doubt that it is constant throughout the exhaust cycle. It may simply be that you software setup has no damping...
