What about a fan blowing the hot air out? Instead of sucking ambient air in? I'm not sure what would happen if the fan ran whilst the car was at speed..... |

The fan does run at speed, it did today on the motorway. I don't think under bonnet temps are too much of an issue but just as an experiment I measured them using a temp probe zip tied to the air inlet for the heater so it was pointing at potentially the hottest area in the bay, up top and high! Engine cold in the sun it was 30 degrees under the bonnet, on a run it was about 40 degrees and stationary it stabilised at 62 degs then when moving again it quickly dropped. On the motorway at constant speed in traffic it was around 35 degrees all of this was done with the bonnet closed. So I don't believe a standard car need louvres at anything under 30 degrees ambient. Then the power loss thing happened again, under load and going up hill. It doesn't misfire it just cuts out, if you put your foot on the throttle then the engine just dies. Got it to the hard shoulder and waited for 5 minutes and got it started again and off the motorway, it then did the same on the Odiham bypass and this time it would not run properly. It would just start then as you revved it would just cut, missfire and die. Plenty of fuel, 1/2 a tank (I checked inside the tank!). Coil was very hot, 70 degrees with the infra red thermometer. Then after about 15-20 minutes I got it started and in my frustration gave it a really good rev, that seemed to sort it out. It does only seem to happen on the motorway. In the meantime I will switch back to points and carry a spare coil and see if it happens again, if it does then I can quickly swap the coil and see if that is the issue. I know I said that it may not be a fuel issue (I don't believe it is a vaporisation issue at all as it happens whist the car is moving.) but I wonder if the pump is bad and not supplying enough under load causing an air lock. It is new but that doesn't necessarily mean it's any good. |

Lecky ignition or coil or both. Your planned switch to points will determine...classic electronic ignition failure. |

Your next job is remove tank and swill out? I'm surprised it ran at all with that muck in the filter. |

Yes, I had a look in the tank and there is some sediment but with 1/2 a tank of fuel in there I'll wait until its a bit lower first! The tank was spotless when it went in so that sediment must have come from the fuel station. |

Time to change fuel station? Surely they have filters?

I have only used the Shell station on Fleet Road, the same place I fill up the Land Rover. When I pull the tank I'll have a good look in it, there is the possibility that there is an unseen area with some surface rust. If there is I can throw some Bilt Hamber in to get rid of it. |
