The 'E' Type Forum

The situation at the filler cap is not quite the same as deep inside the tank (above the fuel). At the filler neck (and who knows how far in), the air to fuel ratio must surely be a lot more favourable for combustion than deep inside, with a lot more oxygen being present. I can accept that once the ...

This has puzzled me as well!! My explanation (not that it IS the correct one...) is that the wiper arm is a "make before break" type contact, ie, it makes contact with the next winding before breaks with the one it is departing from. Also quite likely that it makes contact with several windings at t...

my actual VW van from 1989 the workshop manual show 2 different values for valve clearance. One is for a "warm" engine, one for cold. Fortunately it's too cold in my garage at the moment so I will not proceed at the moment. I will adjust when we have reached 20°C again. :santa: There is NO WAY you ...

By the way, does anyone have experience with the ambient temperature the Jaguar workshop manual refers to for tappet clearance adjustment?? Sven Sven, I recon you can ignore temperature. According to https://www.engineeringtoolbox.com/linear-thermal-expansion-d_1379.html , steel's linear expansion ...

when you mention metal pipes you actually mean to say steel pipes Quite correct. Those fuel lines ARE mild steel pipes mostly aren't they? With some kind of anodizing on the outside - on my restored car anyway. I doubt the same treatment was applied originally on the inside correct? Thus exposure t...

Frank We HAVE to assume there is rust inside ALL metal fuel pipes. On that basis I suggest as follows: 1) Fit an inline fuel filter between the tank and fuel pump (NOT AFTER the fuel pump) - this is to secure fuel pump operation; and IF there is a metal pipe transporting fuel from the glass fuel fil...

Here is a picture of the scoring I referred to (from the jag-lovers site):
Particles that can cause this kind of scoring can easily jam a fuel feed valve needle wide open or perhaps jam a fuel pump or block a fuel orifice?

There has been a bit of focus on the choke mechanism on the V12 in a few S3 threads. I noticed that many of these choke mechanisms show severe signs of scoring where two flat plates slide over each other and I wondered WHY that would be, given that the fuel reaching the carbs OUGHT to be rather free...

Is the timing chain tensioner retracting tool necessary? You don't need it to get the cam sprockets off, I suppose, but you surely will need it , or something like it to release the tension on the chain to be able to get the sprockets back on. Be sure to release the locking catch on the tensioner B...

"Vacuum advance (vacuum direct from intake manifold)" This is WRONG. It is NOT wrong . I still want to verify this statement but I believe that just about every Series 1 and 2 E-type runs on manifold vacuum advance. A '68 S1 4.2 I recently worked on certainly did have manifold vacuum advance. I cha...

Hi Sven To leave 5 out of 24 valves, will save some labour, but not much really. Ideally, you should have a large selection of shims to choose from. I would therefore encourage you to set them all to .013/0.14 as recommended. Also note the thickness of the shims that you remove from each tappet. Non...

Jérôme The only ways OVERfilling can result (that I can think of now) is if: 1) the fuel pump pressure is WAY too high - so high that it can push fuel THROUGH the needle and seat. It is rather unlikely that a non-EFI fuel pump can do this; 2) the needle does not close fully (floats not set correctly...

Went for a good run, plugs all perfect and no flat spot.

If this success continues what will I do with my spare time!

Randomly tune them out and then start again?

Nice to hear its sorted!

Hi JC

Open road 6-6.5 km/L (I mostly do open road with her)
Town : 5-5.5 km/L

These figures are actual, no BS, after correction for the 3.31 diff. My car is auto.

There is another benefit I forgot about:

Lubricates the exhaust valve stem - reduces valve stem and guide wear.

Philip, I get all of the above except the addition of 2-stroke oil. Can you explain ? FYI, I once accidentally put petrol for a 2-stroke moped (~4% oil) in my car and experienced that it ran smoother. I BELIEVE (no hard evidence..) there to be the following advantages of using 2-SO in our old cars:...

Here's an example of my car 's plugs, which I recon is one of the best tuned S3's in South Africa - IMHO. Inner ones #2 on each bank, outer ones, #6 on each bank: tn_20181103_132041.jpg Relevant info; The carbs on my car are perfectly balanced; fueling set as good as I can; needles changed to reduce...

Even with unleaded spark plugs can still tell something. (I'm certainly no spark plug whisperer...) It most certainly will tell you if the piston is running rich = very black Too lean = too white and clean I can not see how a spark plug can tell much about timing. Maybe there's something when the en...

B Bank 1. White/light grey 2. White/light grey 3. White/light grey From this info, it seems there is a problem with the front carb on the B-bank. Seems to be running lean almost as if its not feeding any fuel (or way too little). I would remove that air filter, and while looking into that carb (wit...
