    Thanks for the reminder , confirm is - almost 4 turns of camshaft (not crankshaft).  Brain dead just now with sinus infection , can't stay in house popping Paracetamol , may as well kill myself converting pallets into Micky Mouse concrete shuttering ,  now if it were on my drive - I would have to sockets & spanners out in preference  LoL

    Thanks, the coffee and bacon butties are ready, lol will call him tomorrow as he is doing Mother's day

    Try taking off the rocker shaft and remove the pushrods - keep them in order by pushing them through a piece of cardboard and number them. Turn the engine over on the starting handle. If it still locks up the problem is probably with the camshaft/followers. If it now turns freely the problem lies with the valves. A dropped or broken valve could jam the engine if the combustion chamber is small enough, I suppose, but logic suggests it would lock up on one rotation of the crankshaft.

    Many thanks, just need to get time and help from the mechanic

    Remove drive belts from Ancileries just to rule out a problem with them. Does the engine turn with the clutch depressed? I presume 4 turns is the Crankshaft, that would be 2 full turns for the camshaft and fuel pump as they run at 1/2 crankshaft revolutions

    Errrrr, I am sorry cant answer, the breakdown and recovery crew think it might be the oil pump that failed to give the enging freezing

    The fact that you can turn 4 times but not complete the full cyle indicates to me there is no problem at the bottom end or pistons.  I discount a fuel-pump problem (I think it would strip /snap cog-belt).  Being able to bar over just short of the complete 4-stroke cycle , then a brick wall -  that indicates to me a problem on the valve gear for just a single cylinder, if the push rods turn as they should  - then the tappet should be OK .  Of course it could be something far more sinister like a huge chunk of piston skirt unable to fall clear into the sump. On the basis of BIG racket = BIG  £  expensive problem , the noise you describe is not so bad ,  thinking of two failures where I was determined to get home on reduced power , very reduced.  One a valve head had more or less dropped off , the other as a valve hard seat had come loose in a alloy head.   Over 100 miles in first case & 200 miles in second case that I kept the engine running.  After those two experiences - I have held a belief that a mechanical failure is not so bad, that is as long as the engine will cycle.

    It was quite so agree, had a VW Polo, tining belt jumper three teeth grinding was an understaement
