ej20 which banjo for oil/water
Hi guy's made a little boo boo, on the rear of the rh cylinder head there's a water feed for turbo and an oil one, annoyingly both have same thread! Among the 20 banjo bolts lying round from previous engine builds, there's a lot of different sizes, can anyone clarify weather or not there the same size hole in the side of the bolt or are they different??? Don't want to over feed or under feed either water way or oil!! Any help much appreciated

Water is not critical, hole size about 3-4mm from memory and not actually measuring it. Oil has a restrictor in the banjo on the turbo and hence doesn't require a restriction at the head (head not block). the oil banjo therefore can have similar sized hole 3-4mm.
