then the metric factor means new tools.
Well all you really need are 8,10,13,15 mm 3/8 drive (shallow and deep), 18 & 27mm deep 1/2" drive sockets and the same in combo wrenches.. nothing a $50 bill at Sears won't take care of with change to get lunch.. so its not a huge outlay.. 90% of all the bolts on the engine are 10, 13 or 15mm head size. Unless your rebuilding one the 18 and 27 mm can be left off.
