It usually works but I'd feel bad if he didn't catch it. Good call, humfrz.

I'm curious as to why the right bank would be different from the left bank ....

Maybe @Nigelr32 can shed some light on that ..??

It was an early method to address uneven oil flow/pressure issues. The heads were redesigned by MY15.

Oh, OK ....... but if the heads are identical (symmetrically opposed), why would the oil flow/pressure be different from one bank to the other ..... ??

I don't know any more than that. Not enough info in the service manual and I have yet to tear into one.

Hi Puma,

I only too pleased to help. The larger hole goes in the left bank on all eight posts. When I say left I mean your drivers side in the USA. Later engines have all sixteen posts with small holes.

thanks, everything i had found so far (which wasn't much) pointed towards that direction so i am happy to have an other confirmation.

thanks a lot everyone.
