....pipe, does the oil feed come from the block as standard??

i know that on a 2wd the feed is under the inlet manifold in the block, along with the pressure switch

but a mate rang me today saying his head was cracked around the oil feed hole???

he sent me a pic of it and it looks like it is coming from the head,on the exhaust side.



i thought that the feed came from the exhaust side of the block,in a similar position to the 2wd (opposite side obviously)

Anyone wanna clear this up for me
