Re: A tuning question

Clever detective work, imo does indicate early non ex/em cars did not have thermostatic valves. Not convinced about late cars however, 25.32 does show the thermostatic valve. Unless there was an undocumented late model non ex/em that didn’t? What have you got that plugs the hole where the thermostat...

- if you look at the Parts Manual link, you'll see that Jaguar eventually just connected the retard unit directly to the lower left hand carburettor port.)
I'm not seeing this, if true, totally illogical?

Re: A tuning question

Do you have a gulp valve? This thing (C34018), it is a diaphragm valve that pops open on heavy decel, bypassing the carbs. https://i.postimg.cc/GtdB7Wxm/WP-20180803-09-41-29-Pro.jpg Include it in the things to be disconnected and connection (to the balance pipe) plugged. If its diaphragm is perished...

Re: A tuning question

Sounds like you still have vacuum leaks. This is why the revs don’t follow the throttle, the leak is providing alternative air flow, most noticeable at idle when air requirement is lowest and vacuum is highest. When driving, the problem will be less noticeable, the leak will be an insignificant port...

Re: Overdrive S3

Once open the soleinoid is held open by a very small holding current. The Jag 4 speed is a wide ratio box. If you applied OD in all gears, called “gear-splitting”, this is what you would get: https://i.postimg.cc/bN6tYbJf/Document3.jpg Assumption is that the weakest part of these ODs is the friction...

Re: timing mark

On either bank, when pistons 1 (and 6) are at TDC, all the other pistons (2,3,4,5) are at the same level., 75% of stroke below TDC. I note 2nd photo clearly shows Sven’s harmonic balancer and timing plate are original. I swapped mine for XJ12S3 and for posterity I can report these differences, not S...

Re: timing mark

Sven, it may be that your harmonic balancer and gauge plate are not original; my understanding (?) is that all e-type gauge plates folded around the harmonic balancer and the mark on the harmonic balancer was on the front face, NOT on the circumference. Also that the largest number (angle) stamped o...

Re: What Causes Petrol to Leak from the Exhaust

Not sure what yr agreeing with? George has already explained that he leak was from inside the exhaust? I imagine that the carburetor float chamber vents are where they are so that any emanating petrol should not escape, instead should be evaporated and drawn into the engine via the carburettor/throt...

Re: What Causes Petrol to Leak from the Exhaust

I imagine it is to provide a bit of back pressure, just enough to be confident that the float bowls will always be filled, even around the Nurburgring … If valve is in backwards could be significant back pressure (is positive displacement pump) enough to overpower the float valve? Maybe more so if c...

If it is petrol, maybe a fuel line leak onto the outside of the exhaust, dripping off when it reaches the joint?

Re: Overdrive S3

Is straightforward when yr S3 is manual if you buy an xj6 OD box for the parts, just swap the mainshafts and replace extension housing with the OD, screw on an extra switch, job done. Dave from OD Spares in Rugby is recommended for sourcing parts and refurb. Here is pic of S3 box with OD added, fore...
