Hi guys, the engine shop building up my new head has said there are 3 of the rocker shaft springs which are shorter than the rest. I ordered three new ones of part number 11 33 0 634 125 but the builder says these are short also - did BMW change the springs at some stage so the shorter ones are the right ones now?
