Hi guys, I decided not to install the external oiler and I just finished disassembling, cleaning and reassembling my rocker arms and ready to install as suggested by everyone. I looked at the oil hole that feeds the rocker shaft and it looks clear. I inserted a wire that went in about 5 inches straight and hit something solid. Is this normal. I thought that there was an offset channel in the head that connected to another hole which would of not allowed me to insert a wire 5". What am I missing.

Thank you- AR
