Re: Does My Coil Look Big In This ?

Hi Rory,

How did you mount the trigger wheel on the back face of the crank pulley? That looks very neat.

Re: pre-programmed curves on 123 ignition - help please?

It’s a bit disappointing that none of them match the factory curve. More worrying, if it doesn’t do what it says it’s supposed to do. I wonder if they all show the same variance to the instructions, or whether it’s different from one 123 to the next.

Re: E SI with XJ6 SIII oil filter housing-filter bypass?

I’ve just looked on a genuine XJ6 filter I have in my stock. No maker’s name, but it does say made in Italy.

Re: E SI with XJ6 SIII oil filter housing-filter bypass?

I don’t know who makes the genuine Jaguar filter, but it will be made to a controlled specification and meet a set of performance requirements that are appropriate to the engine.

It may well be possible to buy a superior filter, but the Jaguar one will be good enough.

Re: E SI with XJ6 SIII oil filter housing-filter bypass?

If you have a genuine XJ6 filter head, there’s 2 bypasses in the system, and the pressure relief valve. One bypass is internal to the filter element, assuming you use a genuine Jaguar filter. This protects the engine if the filter is clogged, and limits the pressure drop across the filter. The 2nd b...

Re: what to do

Tricky. The car will drive a lot better as a manual. The original auto will be dim witted compared to a modern auto, whereas the all synchro manual stands up well. Being a 2+2, you could convert to a manual overdrive. However, to convert, there’s lots of extra parts to source. Whereas restoring what...

Re: Cooling fan removal

They will come out without removing the rad. It’s a while since I did it, but I think it was with the top hose disconnected, and the radiator tie brackets removed so the radiator can be tipped forward.

Re: oscillating idle and lack of power

Hi Peter, the tool you’re referring to is a set of feeler gauges. Your ignition map looks like you don’t have any vacuum advance programmed in yet. That shouldn’t be the cause of your problem though. Somethings not quite right if you need to set the floats differently to get the same fuel level. It ...

Re: Eagle Lightweight GT

I wonder how much of these limited edition Eagle cars came out of the Jaguar factory originally, or are even new manufactured parts to Jaguar specs? None of the major components, by the sound of how they’re all upgraded. I generally like the look of it, but the low angle photos they insist on using ...

Re: Radiator fluid change.

Do you have a photo of your engine bay, so we can see whether you have the series 1 style or series 2 style of cooling system. The process is essentially the same for both though. There’s a drain point on the bottom of the radiator, and one on the LHS of the block, towards the back under the exhaust...

Re: STARTING CAR WITH FUEL SYSTEM COMPLETELY DRY...

The fuel pump is electric. If you turn the ignition on, the fuel pump will run and self prime the system. When it stops ticking, the float bowls are full.

However, if the car hasn’t been run in years, things may be gummed up. If the needle valves are not sealing, you’ll risk fuel overflowing.

Re: 4000 rpm limit 123 distributor

If it’s the slave cylinder that’s gone, it will have dumped all the fluid on the road. If it’s the master cylinder, it will either leak into the footwell, or fails internally so it just pumps fluid back and forth between the cylinder and reservoir. The flexi pipe from the reservoir can break up inte...

Re: 4000 rpm limit 123 distributor

Hi Grant,

The factory distributor curve is also in the electrical section of the genuine workshop manual.

Unfortunate about the clutch. Which cylinder has failed?

Re: Does My Coil Look Big In This ?

A couple of points to consider. Later cars have a mud shield in that area, which protects the air intake. It wasn’t on the early cars as built, but I think it was suggested as a potential retrofit by the factory. With the coil pack there, you won’t be able to fit it. Fitting the coil pack so low als...

That hole looks too precise to be someone’s bodge. Is your car new enough to be of the era when US cars got a 2 way switch on the driver’s door?

Re: pre-programmed curves on 123 ignition - help please?

That’s not ideal. The cap on mine is an allen head plug. I guess in the interim, any short section of bolt of the correct thread, or even some tape over the hole will suffice. You should be able to rotate the distributor 180 degrees so the access hole is facing outwards. It’s still awkward to get to...

Re: pre-programmed curves on 123 ignition - help please?

True, but it depends how you quote the curves. The different 123 manuals do it different ways, confusingly. It’s either: “With the LED set to X degrees, crankshaft advance is Y degrees at Z rpm. Or it’s: At X rpm, the advance is Y degrees beyond idle, at the crankshaft. The latter is closer to what ...
