Hey folks Iíve got a 2012 crafter with engine code ckuc and am trying to fit s new crankshaft oil seal as the old one had the crankshaft sensor stuck in it, only problem is that Iíve got engine locked at TDC but the tool to fit the seal behind the flywheel wonít align properly, Iíve tried moving the locking tool by one tooth on the crank but no joy! Is there any chance that the crank could be twisted? Cheers
