  1. "Lotus Marques" in Australia may well have them. Steve has a range of new track rods.
  2. Most engines irrespective of age like about 5-10 degrees at idle/800-1000 RPM advancing to a max of 30 degrees at at around 2500-3000 RPM. It would seem to me that 20 degrees at 1000 RPM is too much advance.
  3. Thanks Ian, I will see if it will do the job.
  4. Thanks Andy, I am in Australia but will try to contact MT. I purchased a few bits from him when I was in the UK last October. Very knowledgeable and friendly chap. David
  5. I am currently trial assembling my engine. Are there any modifications that I should be making at this stage to ensure longevity or oil-tightness? I am not looking at performance changes, just reliability and oil tightness. Perhaps somebody has done a blog or a thread that would assist me.
  6. I am currently assembling my 907 Elite engine and I recall that there was a modification that could be made to the cam carrier to reduce the chance of the oil leaking onto the exhaust manifold. I have done a quick search of the archives without success. Is anybody able to point me in the right direction?
  7. I am currently assembling my 907 Elite engine. I did not notice it when pulling it apart but the cam carriers appear to have no location dowels into the head. They float quite a bit on the studs when trial fitted. Am I missing something here? If there are no location dowels how can one be certain that the timing drive wheels on the front of the camshaft are truly square to the crankshaft? I guess I can set up a dial gauge mounted on the crank and sweep it across the drive wheel by slowly rotating the crankshaft but that should not be necessary in a properly engineered engine.
  8. Thanks Michael, I have the later loaded lip seal so I clearly do not need to try and locate the missing splash guard.
  9. Fair enough, I guess you will soon know if it is acceptable when the car is presented for an engineers inspection on the modifications ( I presume that such an inspection has to be done in the UK.......certainly here Down Under it would be required).
  10. Nick, I must be missing something in the design, although looking at one of the earlier pictures I see that the bend in the trailing arm is actually braced with a small triangular piece which helps strengthen the corner.. If you removed the trailing arm altogether how would the force of the rotating tyres be transferred to moving the chassis forward. The driveshaft can only locate sideways and not drive the chassis forwards. The bottom arms fundamentally again locate sideways. I can see that given their "T" shape at each end (of each arm) they can apply forward force to the chassis but the loads being fed into the inner points on the chassis would be very large due to the very small distance between them (the inner bearings). I guess if this was the only pathway used by Jaguar it must be strong enough in which case why do you even have the trailing arms?
  11. Constructive comment........... Just looking at the inner end of the trailing arm.......... all of the force needed to drive the car forward (generated by the Lexus V8) is applied through those two links. They have a welded section at the forward end. Are you confident that the weld is strong enough ? I cannot see any bracing on the inside of the corner which would help. Welds in tension like the outer "radius" of that bend are not a good idea. Possibly OK in a low powered light race car but when trying to shift a tonne or more of car with a high torque motor I would think carefully about the integrity of that weld.
  12. Thanks guys, I will not stress about it being missing.
  13. My son started to assemble the 907 engine in his Elite today. One item which has provided us with a query is a missing item. The manual shows a "splash guard" which is located at the rear of the crank. When the engine was pulled down we did not notice that it was missing, only upon assembly did we note the missing item which is shown and mentioned in the manual. We are not sure what it is meant to do. It does not rotate with the crank so cannot act as an "oil slinger". According to the picture in the manual it just sits there. So, can somebody please shed some light on its function and whether or not the engine will leak like a sieve if one is not fitted.
  14. That big lump on the right is not going in is it? The front springs will collapse
