    Yes I think youve demonstrated the problem but by putting the cam in the rocking position you'll be able to see how many degrees away from TDC the crank is. This might even give you an idea of whether youre a tooth, half a tooth or even a quarter of a tooth out on the cam sprocket...

    Follow the manual, its not perfect - there are some minor errors and easier ways to do things but it'll get you there. You almost did it perfectly first time but then deviated at the last minute😁

    The manual is just using the rule of 13 (six cylinder) so you have valve 1 on the back of its cam when valve 12 is fully open. Here though we're then adjusting tappet 1 to 40 thou for the purposes of using the rocking method to set cam timing which, as you know, means valve 1 and 2 cam lobes should be at the same heights at TDC cylinder 1...

    I wonder if the vibration of the loose rocker shaft shook out its end cap pin....
  5. johny
    just another bad sign and I wonder what the head bolts were torqued up to!
  6. johny
    but I can see the end of the rocker shaft (minus its cap) moving as well. Probably just needs the pedestal bolt(s) tightening....
  7. johny
    My emphasis. You set the gaps wide on valves 1 and 2? That are on cylinder no.1? That would be completely wrong! One of these quotes has to be right....

    Its just that in one of the photos the rear seat surround is white and I thought they were usually colour matched but I suppose it could have been changed and never repainted...
  9. johny
    Thats it and there should be some sort of short coil spring with it that pushes back against the rocker and of course a pin that may or may not have ever been used...

    Ah sorry read original post as cylinder 1 so 4 is more understandable. Any chance the rocker shaft end cap fell out as you removed the cover? Could it be in the engine bay or garage?
  11. johny
    Either way (TDC exhaust would have had both valves open) I think theres something wrong with the valve timing so yes drain coolant, rad out, pulley off and then cover. Check chain/sprocket and crank seal ring condition, replace tensioner, gasket and seal? Using manual set valve timing and ensure cover fixings are put back in correct places... Then drive off into the sunset at max power😁

    Not sure you got the procedure quite right as of course theres two TDC positions for piston 1. After setting the gaps I would have turned the engine until valves 1 and 2 are in rocking position and then see where your pulley indication is (TDC firing)....
  13. johny
    yes that was my postulation but why did it wait until then to do it? Ahhhh but was the end cap in place, though loose and held on by the rocker cover, so that then on removing the cover it fell out somewhere and the rocker was free to slide along? However was the prior loss of compression on the same cylinder pure coincidence🤔
  14. johny
    See my previous conjecture although I now see this engine doesnt have collets as such - the spring cap has off centred holes so you put it over the valve stem (spring compressed) and then slide it over to lock. However I think it could still be released as I suggest but what I dont understand is how the engine ran so long with the rocker shaft end cap missing or how the loss of compression (the original problem) is related....

    Two post car lift

    johny replied to Pdv's topic in General

    Also look on ebay for lifts, some including installation...

    I agree with you Dan, engine highly unlikely to be a GE either. All indications point to it being a 1147 (GB?)
  17. johny
    yes and as I say except for the chrome its a bit humble compared with Unkels all singing, all dancing jobbie😊
  18. johny
    I think it might have had a colour change somewhere along the line having been white originally....
  19. johny
    Yes if only they did a chrome version😍
  20. johny
    Triumph are famous for the often poor quality of the stamping of serial numbers on components so I wonder if it isnt GE that looks like an F? Easily done on the production line or maybe the other guy was using the E stamp already....
  21. johny
    Wow Unkel that is a posh one! I was thinking of one of these:
  22. johny
    Hmmm yes some suppliers arent so quick when theres no money in it...
  23. johny
    Ask the supplier?
  24. johny
    yes the good ol days with a wodge of cash! Not the same now waving your phone and saying youll do a bank transfer but a bit safer I suppose😁
  25. johny
    Cant make out how the valve came free! Oh yes I can - without the end cap the rocker moved along the shaft and pushed on the valve spring cap instead of the valve stem so the collets fell out and the valve was free to fall into the cylinder. It might have then been pushed up by the piston against the valve guide so that got forced out of the head🙁
