If it is just the case of a washer it will just be a genuine mistake so ano everything will be fine was just bugging me what has happend that's all
the lol and hand on head meant that you said the engine was timed up all ok!
well if you cant see the crank mark then how on earth would you know that as 2 timing marks on cam sprockets means nothing without the bottom mark being in relation to timing pointer
yes is a genuine mistake but one which will cost you bent valves in possibly every cylinder and damaged pistons also plus theres a good chance you have damaged the chain and crank sprocket also as well as the locator being broke off of bottom of oil pump (stops chain dropping)
on top of that you may well have damaged camshafts, rockers, the cylinderhead itself, and snapped shims....even if they are all in one piece now they could well have strss fractures causing them to fail at a later stage.
basically i would trash the whole lump and start from scratch.
ultimately your to blame because if you knew you were 3 washers short then why on earth did you not try to locate all 3 of them before cranking and starting the engine....at least just turn it over by hand to see if it was jamming anywhere in which case you stop and find out where its jamming and remove the gremlin before you destroy your engine.
so very harsh lesson learned there which should never ever have happened
