  1. yes 5% was always allowed to be mixed in any petrol even without advising the customer as its deemed not to have any effect. Over that does have to be labelled.

    The good side is that ethanol actually raises the octane level, the bad, the manufacturers take that into account and lower the octane of the rest of the mix to compensate☹️

  2. I got a thin sheet of rubber (petrol resistant) and cut my own gasket using a paper hole punch to do the screw holes. Worked a treat without sealant and has allowed me to remove the sender multiple times while I try to get it reading more accurately!

  3. ah fan mystery resolved and things are looking better - definitely a case of a picture is worth a 1000 words! No expert on viscous couplings but would imagine that with the engine off and cold the fan should turn easily by hand but with the engine just turned off hot after a good run, the fan will be harder to turn by hand. This is important as believe these couplings can fail and then affect cooling at slow speeds....

    Hi. I think my door seals are not fitting great (correct profile ones, bought from Bill Davis) and water coming in. I was wondering if to slide a piece of paper in between seal/door, to find any tight/loose areas, then to bend the seal flange a bit, to correct, as the door fit appears not bad in general.

    Do you think this would work.

    Cheers, Dave   

    Thats exactly what you do Dave. Obviously its a combination of getting the door sitting correctly and the seal compressed the right amount all the way round. You could almost remove the seal completely to get the door position correct then refit the seal and tap the flange in or out to ensure it seals well without interfering with its closing. Dont forget that the quarterlight frame is also adjustable (and bendable) to get a good seal on the front edge (and roof on a saloon) which is important as a lot of wind noise can come from this area.

    I think Universities should offer a degree qualification just in door fitting......

  5. yes its quite a fiddly job but worth spending time on as you want the rubber seal making a good contact (but not too much) with the door all the way round, the door gap the same all the way round, the door line matching the body plus the door flush fitting and latching smoothly....

  6. well one correct arrangement would be a fused supply to an adjustable thermo switch measuring coolant temperature and controlling a fan. However there could be a relay, different types of fan controllers (or none), manual overide switch, indication light etc 

  7. sounds like you have an electric fan which isnt standard fitment. This makes it more complicated because you dont know how its been wired up so I would first work out how this has been done and do a drawing. Once you know this you can work out if its been connected correctly and where the fault might be....

  8. Yes car designed has improved a bit in 50 odd years! Your Spit unlike modern cars hasnt got a closed radiator system so as the engine warms up water is pushed out of that overflow pipe into a reservoir bottle. This bottle should be kept about 50% full when cold and the overflow pipe must must always be well submerged in the coolant so that when the engine cools liquid can be drawn back into the radiator.

    Dont know about the dipstick but it surprises me that its that difficult to access!

  9. Also you can get quite a good look inside the tank in situ from the level gauge. Obviously you have to get the level low enough beforehand but then with a torch you can get an idea of the state of the tank interior and fuel contamination.

    I agree with Dave about not overhauling the pump unnecessarily. You can check the diaphragm visually and the valves by blowing/sucking through each one as appropriate.....
