  1. Overheating fuse but not blowing is the typical symptom of a sustained overload. I wonder are the fans just running for too long a period. Where I am going with this is that the fans might be over worked due to another issue in the cooling circuit. I remember I once had an issue with overheating on my Eclat and after much head scratching I eventually found the the boss that is pressed onto the pump shaft that the pulley wheel is connected to was turning while the pump shaft was not. The tolerance between the impeller and its housing is very small and when the boss moved, the impeller would jam and so stop pumping, then it would move and pump again. Because I had an overheating problem, my runs were short, so it took fooking ages to see this issue. A replacement pump soon after sorted that issue.
  2. Shocking about the chassis. However a timely reminder for us to check our fire extinguishers and fuel lock valves.
  3. Nice car and welcome. The steering is heavy at low speeds and made worse by the lack of ackerman geometry so the outer wheel will scrub whilst making slow low speed turns. That being said, it should lighten up as your speed increases. Its worth checking the universal joints on the steering column (there are 2) in the engine bay as these are prone to seizing.
  4. Hmmm. High temps at motor way driving or fluctuations may point to water pump issues. There is a critical distance that the impeller needs to be from the back plate of the pump to make the flow rates. From memory, the impeller and shaft are just pressed in place so the shaft can move although you would normally expect to see a weep from the tell tale hole.
  5. Can you not just wire a switch in parallel across the thermostatic radiator switch? That would leave you with just 2 wires to run into the cabin to your manual override switch.
  6. Try fuel cut off solenoid. Mine was loose on the chassis (so poor earth). Mine gave me all sorts of spurious loss of power issues until I discovered that. (I also had the vacuum issue in the fuel tank)
  7. Hi Pete, covered 16,340 miles since the drilling of the casting. Some of those miles were in Spa, some in The Alps and some at home in Mondello. I examined the Inlet cam box and saw that it had its drains located so that its orientations allowed most of the oil to drain back to the sump. But the exhaust cam box has the drains in the same location but the orientation of the exhaust cam box meant the oil accumulated in the cover. So I did not see that it was necessary for an oil bath in the exhaust cam box only for startups. However, I stand to be corrected.
  8. Exhaust cam cover leaking is an age old issue with the early style cam covers. The seal slips out of position so easy during fitting and you typically do know about it until the day after your inaugural run. However there is a partial solution. With the inclined engine design, the oil pools in the exhaust cam box and whilst the car is in motion, its not really an issue. The problem starts when the engine is stopped. All the oil collects in the cam box above the cam cover gasket line and hot oil needs not be told twice about a poor seal. Out it leaks all over the hot exhaust manifold. If that does not catch fire, then it will smoke like a train on the next start up until its all burnt away. What I have done to alleviate this issue is to drill out 2 holes in the the cam box in chamber 1 and 4 as per the pictures. This means that the oil will drain away to a much lower level in the cam box, all below the cam cover gasket line. This is how bad it got on my Eclat. You can see the pilot hole drilled in the casting. This was increased to the full size of the casting plug. No. 1 Chamber. No 4 Chamber Only downsize to this modification is that the cam box needs to be removed and its not so easy to do with the engine in the car. Its not impossible but easier with the engine out. Thought I would share this for all to see.
  9. Engine oil - every 5000 miles or after a trackday Gearbox oil - every 5000 miles Diff oil - only once ever Brake Fluid - yearly or after 2 trackdays Coolant - tested yearly After that, its greased yearly on all joints.
  10. My speedo drive sprung a leak so I removed it last week! The speedo cable is connected to an angle drive gearbox which in turn is connected to the speedo drive assembly. My gearbox is a 265 in an early S2 Eclat. Its fiddly as everyone has said but manageable.
  11. Lads, Just loving this thread and the tuning options. I have an Elite that is engine less at the moment. I had 2 options in mind, all electric or Lexus V8. Watching this thread with much interest. Michael
  12. When positioning the grease nipples, make sure they don't foul against the lower arm also.
  13. Some of the earlier BMW and Mercedes used a 12Vdc Water Pump to do exactly this. I retro fitted one such pump to a series 1 Elise that was modified with flowed head and throttle bodies. The head gasket was only lasting 6 months! Now the rover engine was famous for blowing gaskets anyway but still should have been better. We opened up a blank port casting on the head next No. 4 and plumbed the pump between this and an existing connection at No. 1. This ensured a timed flow of coolant around the head once the engine was turned off. This Elise has the same head gasket now, 4 years later. I always had it in the back of my mind to do the same to my Eclat but no amount of hard driving caused me any concern once I had my manual override on the cooling fans.
  14. My car had 2 rusty mild steel pipes for the heater matrix. They both came from the the bulkhead just above the flywheel housing, around by the battery onto the inner wing. 1 terminated at the expansion tank via a small flexible hose and the other just past the expansion tank, connected to a center outlet on the water pump. If I remember correctly, I used 15mm stainless steel pipe with barbs welded on each end.
  15. When I did the partial restoration on my Eclat, I prioritized the following over an alloy radiator: Fit a manual override switch on the fan (s). Replace the rotten mild steel pipework for stainless on the header tank and heater matrix core. Fit isolation valve on heater matrix core piping. (I was not brave enough to remove the dash to replace the matrix) Re-core the radiator.
