    Well, it might just be the vacuum pipe to the fuel pressure regulator split or come off. Although not on a K series we had this on a pals BMW 525 only last week. It was massively rich simply because the fuel pressure was being set relative to full atmospheric pressure rather than the manifold pressure (this would be OK if you could keep the engine under very high load all the time but the BiB seem to take a dim view of this sort of driving 😬) Edited by - Colin Mill on 21 Jul 2009 08:56:31

    My Younger daughter just phoned to report this sighting!

    There are Archos devices with hard disc storage and others with solid state storage. The 604 can have 30Gb HDD or, I think 10Gb of solid state. My guess is that the HDD versions would need a lot of anti-vibration mounting to work in a Caterham but the solid state ones should be OK. I use a 30Gb 604 for wildlife filming at remote sites and I really like the quality but I have not used it in the Caterham. BTW Archos are quite good at extracting cash from you for the extras you need - the DVR travel adaptor is needed to provide an AV input to the 604, 605 units etc. however the units themselves are pretty good value for money IMO.

    I know I'm an old nit-picker but since the idea is to reduce the amount of dissolved water and gasses in the system the fluid in the reservoir is likely to be the worst of the lot having sat in a partially vented container for years. I avoid pumping this through the system by syphoning the reservoir out and filling it with fresh fluid as a starter - then bleed the system.

    Thanks Jason I'll give them a call.

    I want to do a couple of minor cosmetic repairs to surface cracks in the standard Caterham green wings on my 7. Does anyone please know a source of gelcoat to reasonably match the colour of the original?
  7. Colin Mill
    Yes, I would like to have that explained. Looking at the frontal photograph it looks to me as if a sideways force of about 30% of the weight of the car+ ramps would potentially topple the towers unless the towers are cross-linked. This, of course, is true of axle stands also.

    My guess its the 1-2 selector rod that is not quite in the neutral position that will be stopping the thing. A shove on the selector forks (if you can see them) might get it back in place. With the top off the box I would have thought you would be able to get enough access. Good luck!

    The 'box that came with my kit did something similar. Luckily it was still out of the car at the time and CC swapped it out for me. If it has skipped the detents it can be a real struggle to get it back (I have a Massey Ferguson that does it from time to time)

    What I loved was the first bullet point in the data sheet - Over temperature shutdown. I think it's fair to assume this is not an infallible feature 😬
  11. Colin Mill
    Data sheet for you 😬 here

    If it's an 8 pinner and its used to drive a tachometer there is a reasonable chance it's a 555 timer IC but it would take a bit of circuit tracing to confirm it. Also, charred chips usually mean something else has gone west.

    Being a cheap-skate I modified a 3amp 15v switch-mode supply to output about 13.5v as a maintenance charger that pulls zilch off the mains when lightly loaded and thus far its been great.
  14. Colin Mill
    Sorry to say it but 16.2v sounds like a recipe for an overcharged battery unless it's got some processor in there and is simply using 16.2v as a way of detecting when the battery is connected and backs the voltage off to, say 14.4v for bulk charge and 13.8v for float charge once the battery is connected.

    The intake manifold gasket could be leaking such that water is getting into an intake. A pal did the HG on his Rover 400 only to find his problems were this gasket all along. Worth a look.

    Oh - lets not start that one again 😬 You may be surprised - I thought the fan on my daughter's Cinquecento (don't laugh) was running backwards because air seemed to be blown out of the front but it was actually going the right way (though the rad was rather blocked up so may have had something to do with the illusion) Edited by - Colin Mill on 7 Jul 2008 11:11:25
  17. Colin Mill
    An easy way of checking if the fan is running backwards is to look at the camber of the blades. If, looking at the fan from inside the engine compartment, the side of the blades facing you are concave then the fan must be running backwards as the camber being that way around shows that the fan was designed to pull air through the rad into the engine compartment. Conversely, if you are looking at the convex side of the blades then the fan was designed to be in front of the rad blowing air through the rad. (In short - convex side = input to fan. concave side = output of fan)
  18. Colin Mill
    I would have thought that having the fan blow air forward against the natural flow was not a very good idea. There would be a steady driving speed where the fan and the forward motion of the car would tend to cancel out leading to an overheating situation. Also, at high speed I would have thought the airflow through the rad could stall the fan or even drive it backwards leading to a very high current through the fan motor - possibly burning the motor out.

    You can see why BMW gave up on belts and went back to chains back in the 1980s
  20. Colin Mill
    Good point! It would be a useful sum to do for the Elise so one could keep an eye on any abnormal level changes.
  21. Colin Mill
    The interesting thing about this is that when you do the sums on the expansion of the water (or strictly water/EG mix) it can only be about 200ml. I have confirmed that with my engine and keep the header such that this expansion significantly compresses the air space in the header. This raises the question, if someone is getting a rise in the water level in the header much greater than this what is providing the extra volume? Edited by - Colin Mill on 1 Jul 2008 19:49:02

    I can get hold of 35Watt ones in power transistor type packages (TO220) designed for bolting to a heat sink (like the car 😬) Like Ian, I can't see why it should be constantly under load - sounds like a fault!
  23. Colin Mill
    Interesting - does a diff have oil ways?
  24. Colin Mill
    Sounds like Redline have some diff lube that the old-time car dealers would approve of - see here Does this stuff also magically weld up the hole in the crankcase where the big-end went through? 😬 Edited by - Colin Mill on 27 Jun 2008 13:03:22

    Brazilian Rosewood dust then 😬
