I was wondering if someone could help me, I need to know what holes are for what on the back of the block I see on hole that accepts a m12x1.25 drain plug I believe that is the mivec oil supply but I see another larger threaded hole below it, I have no idea what its for. Does anyone have anypictures of a assembled 9 block?

 

that is a access hole for cleaning up the oil galley on the motor it should be blocked off

 

I think he's right, the upper one is the Mivec feed line outlet. It's the same location as the oil pressure sensor hole on the 8 block, but it's much larger on the 9. I just did this swap in my 8last month. The lower hole should have a plug in it, but I have no idea what the thread would be.

 

NICE!!! Im sure I can figure out the thread size....I was just worried something was supposed to go ther.....Thank very much!!!

 

I ordered the plug from the dealer thanks again people!!!
