    think i would buzz through the tappets again to loose some of the sewing machine noises 

    thermostat 82C    needs  air bleed jiggle pin in the rim to aid refilling by letting the air out when closed 

    but you can just drill a 3mm hole in the rim ,thats works well enough 

    so those are call ed moving iron gauges , dont need a voltage stabiliser the gauge workings balance 

    any voltage changes . s

    these use a very different sender unit is 121997     very different to the one for stabilised gauges if you mix them up and get some daft hot readings 

    £3,25 from james paddocks stock them if you think the gauge is misbehaving 

    Pete

    I'll get the thermostat and see how the gauge behaves. It's always made sense in the past

    check the earth connection in the distributor, the small wire that goes to the plate that holds the points electronic ignition. If you dont have that wire the plate is earthed thru the rotating parts of the plate and this can start to fail when it gets hot.
    Had a GT6 that had this problem....

    I re did this connection to make sure.

    Thanks

     

  3. Ok.

    Stand by for some classic "Paula" 

    I cleaned the plugs up and got him running again. Sounds pretty noisey i think. Like there's more low end noise. Like a grumble.
    Anyway.

    Went for a drive avoiding traffic and he runs fine. There was a point where i heard what sounded like something was clunking around in the engine. I thought i had maybe left a spanner on the engine or something, but it sounded bad. I turned around and came home. The noise didn't come back. 

    I got home and got my IR thermometer out and checked the top of the thermostat housing. 85'c

    Then i checked the radiator 30'c 

    So i guess that's the thermostat not opening. I swear i checked it, but i did boil it in a pan. So maybe it isn't opening early enough.
    I'll get a replacement and then check again. I am a little worried about the weird noises. Tappets are a bit noisy too, but i can adjust them.
    I took 2 videos so you can hear it (should you be inclined!). One before i set off and the other is from me accidently leaving the phone recording in my pocket. It does pick up the clunking sound though

    Oh and Sorry @Pete Lewis The gauge is a fast type one.
    Any tips on the best thermostat to get?




     

  4. It's a slow meter. It does seem to drop down quite a bit once i get moving again, but by then the plugs are fouled up.
    The traffic around me at the moment is much worse than normal. Lots of temporary traffic lights. You seem to go from one to the next. It's almost like they are doing a coordinated attack!
    Maybe it's just that?
    I've adjusted the carbs so they are slightly lean. 
    I'll try all the things mentioned and report back!

    Paula,

    I don't trust temperature senders!    Especially modern replicas, that go off in months.  They can under and overread. 

     Check with an IR 'gun' what the actual temp is at the thermostat, or take out the sender and  calibrate it, in a pan of water, over a camp stove,  with the IR gun, or a cooking thermometer:

    Extend wires to the sensor in the bath to the loom and a good earth, so you can read what the gauge says on the dash.    Then you KNOW what "3/4" hot means!

    John

    So I might be overheating. I’ll look into it

  6. Dammit. Spoke too soon i think. 
    He's running lovely even when left idling for a good time. But after about 30mins in traffic he starts to run lumpy and eventually only runs on 4 or 5 Cylinders.

    One of the plugs is wet and most of the rest are sooty.

    I've checked the carbs and they are not running rich as far as i can tell. I've replaced the coil and the electronic ignition. I've also put new plugs distributer capo and rotor in.
    I'm starting to think something else may be wrong. Maybe valves seals?

    It's a shame because he's running like a dream up until the long time in traffic. 

    He's overheating a little maybe but hardly at all over halfway on the gauge and that's after a long time in traffic.

  7. Well here i am again.
    This one's stumped me.
    It's running very well and keeping cool until i've been stuck in traffic for a long time or i'm giving it the beans on the motorway. It runs fine until i put my foot down and it runs lumpy and starts to lose power.
    This gets worse until i'm limping home and breaking down outside sainsbury's (where you see everyone you know!)
    I have to let him cool down and then limp home. It doesn't recover until it's completely cooled. Then it's all good again.
    The plugs are very sooted up. Changed 4 of the plugs (all i had in the boot) I've flushed and cleaned out the cooling system and checked the carbs. When i push the little button to raise the carb damper piston the revs rise slightly and then settle down to idle.

    I've changed the distributor cap and rotor that was badly corroded. (when i saw that i gave a hurrah that i later had to withdraw)
    I've checked the thermostat. I've changed the air filters. Put a new fuel filter on.

    I'd like to check the fuel pump, but it seems to be fine when i remove a pipe it has a good squirt.

    Any ideas?

    but that depends on your age and outlook .

    just something a guy taught me all those years ago  Ha 

    pete

     

    I'd take 38 for sure!

    I'm all good.
    Feargal is being a right pain in the bum at the moment though. I'll post on my own thread all about it

     

  9. All back together and he’s refusing to start. Just turning over slowly. I’ve tried jumping from the van but that’s not making any difference.

    I can turn the engine over fine with the fan. There’s fuel as I’ve also flooded the carbs and they are now dripping.

    I feel like it would start if I could get a good crank on it.

    weird how the jump doesn’t work from the van though.

  10. The head and block are all lovely and flat. I checked with a brand new steel ruler.
    I wonder if the whole problem was the lack of little hole in the thermostat all along!
    I'm waiting for my Stud and Wellseal to arrive before putting it back together so i got the paint out.

    Do i just do a very thing smear of the Wellseal on both sides of the gasket when it finally arrives?

    well the easy job is add a 3mm drilled hole in the stat  rim.

    if you remove the studs and use a hard block to sand the face clean you will soon see if any hole has a raised periphery it will shine up before the main face 

    things like a step drill/cone cutter are good for adding a shallow countersink to an exitisting hole 

    and lots of other odd jobs

    I have a new thermostat coming too.

    I do have some step drills. That is slightly terrifying though!
