- Also buy 2 crankcase hoses, Toyota part number 12263-46010 & 12264-46010 (if needed), if you have not replaced your hoses in a long time, chances are you going to have a hardened crankcase hoses that will get damaged on removal, its always a good idea to save new ones just in case you need them one day.
Remove the two crankcase vent hoses that run between the valve covers. if they are hard to come off, clamp them in the middle with pliers and twist the hose.
I had to use a knife to cut the hoses off. New hoses cost £14.14 and use the pliers bit, works a treat.
