Well engine and gearbox are out and on the stand, gearbox removed then engine stripped down. Cylinder head off for skimming at machine shop , couple of extra parts ordered like sump gasket, oil filter, inlet temp sensor. Headgasket was blowing on cylinder 1, not suprised with its condition !! Cam shafts and bearings all in good condition, Starting to think this may make a fairly noticeable difference to the performance More pics to follow
