... I don't see how they got around the problem of advancing the ignition under acceleration without a vacuum....!

The opposite applies, in that light cruise vacuum advance is *abolished* under hard acceleration.

Probably wide angle heads for starters, plus billet crank and dry sump. That’s £25-30K in parts alone.

Yup.Flange only, sealed with copper/asbestos flat gasket. At a pinch you can fit XK downpipes to E manifolds but not vice versa. Look on the bright side - you won’t make that mistake twice :-)

I agree ‘Death Valley’ gets very hot, especially if an AC compressor is fitted. It eventually proves too much for 1970s components in the Opus amp, which do better up front on the picture frame. I assumed you were talking about the smaller cigarette-packet black amplifier fitted to XJ6/ XJ 12 and XJ...

I didn’t when I used vented cap, formerly used on the petrol tank of Matchless scrambles bikd.

The RB14 (same as XJ6 amp) needs a heat sink as well as an earth. Originally the inlet manifold served both purposes but placing for airflow may mean heat sink effect is forgotten, leading to shortened life.

The Jag situation is different in that the cars are as new as a current showroom model and therefore incapable of passing any of today’s crash, safety or emissions standards etc. Just because it’s identical to a 50-70 year old car from the same company (ish) and has an ancient VIN doesn’t mean it on...

How is it that countless replicas from Lynx to Challenger, or Realm to Suffolk, Proteus et al don’t have Q plates? Some are based on 4-door Jag donors, some on Es, but all are more altered than a decapitated 2+2?

The whole Trunnion is removed from the shafts.
This applies to all Makes and Models, not just Jaguar.

It doesn'y apply to all E-types, never mind Jags. Some Series 1 cars have the top yoke of the lower UJ lntegral with the column forging

Everything under the sun can be argued Peter, if you have a mind to. And just about no sealant is fuel proof, as I discovered when I tried to stop my SNGB 3.8 fuel pump from leaking a few years ago. I agree Andrew, which is why I only said ‘arguable’. As gasket dressing it’s OK as the fuel should n...

RTV silicone is not fuelproof, ergo use on the intake side is arguable. Hylomar or Hermetite would work for coolant and fuel.

My timing is too advanced, as I have three engines on the go right now. Too early for this bit of kit, and probably only ever one or two more in my future. Pity. On Friday I took the stripped 3.4 D block for boring to 3.8. Yesterday I had to take the 4.8 off the stand to do the rear seal. and the fu...

Just had a quick look at XJ jack's- I think the price of chips may have gone up recently... ;-)

PM me if hungry...

Looked on Fleabay and like the look of the electric jack (cause i'm bone idol). Could someone tell me if item 163554080937 £35 ish would suit my S3 Roadster as i have no clue. Your item number didn’t come up but nobody with any 2+2 or V12 can use the square pad SWB jacks in this thread. Instead the...

One would hope the contacts are.not plain steel! They should be at the very least copper and ideally copper base with a proper contact material on top to prevent them welding together :bigrin: Steel rusts and is not as good a conductor as copper...important in high current applications. Pure copper...

The moving solenoid is fine by the sound of it and the motor part must be OK if it ever spins. What I think you’ll find wrong is the internal connection where the solenoid pulls two crude steel parts into contact. I’ve dismantled a few and from memory the iron core pulls a big washer against two ste...

Not essential really..It’s a simple brass stamping to keep the base of the big soggy spring concentric with the damper tube. I assume it prevents the base of the spring skidding sideways and the spring becoming fractionally less linear if it skews and rubs the casting, but most carbs either no longe...

Agree Clive. Didn’t know the numbers.

You doubtless gave them but my sight is a bit blurry, due to meds given in ER where they are fishing a bit of alloy grit out of my eye. Shoulda worn goggles drilling under the D :-(

Mahwah/Mike Cook were always a bit chesper than UK but I believe they have lost the ability to issue certificates in USA / CAN / MEX at the same time as the UK has raised prices.

I took the answer to mean they switched supplier some time ago but after you bought your stud 18 months ago? The waisting is a bit like the collet groove in a valve stem - it’s a weak point but not necessarily critical if the diameter is the same or larger than, say, the minor thread diameter. I nev...
