Had to make a crankshaft sprocket holder out of some 6mm flat steel I had in stock... Done the job combined with a couple of offcuts of 4x2 despite the bolt being the tightest bolt I've ever removed in my life! Manufacturer spec is 180nm + 135°. On reversing the tool to tighten it after replacing the wee belt an refitting a used oil seal I didn't have enough clearance for the breaker bar so did it up as tight as I could get it with the jack handle over a T bar.... I doubt it's even got the 180nm nevermind the 135° as it is. Still, my neighbour is back and getting me the gun for tomorrow (hopefully, he loaned it to someone) and the bolt head is still accessible with everything bar the wheel arch liner replaced... which is where I'm at as far as the front of the engine is concerned, just the sump to refit now which I hope to do in the next day or two, weather permitting... with a view to buzzing the crankshaft pulley bolt as tight as the gun will go in due course. However, the timing belt tensioner pulley is a bit dodgy (not springing as freely as it should) and ought to be replaced but the cheapest kit in Ireland is c.€160 which I can't justify without knowing that the engine is still capable of running. I've already spent €52 on parts and €56 on tools so no point in throwing good money after bad. I'm kinda thinking/hoping that it'll probably hold long enough to determine whether the engine is still a runner in which (however unlikely) case I can reassess the options, I guess!
