Ok, car landed in my shop with parts included (ugg) customer didn't tell me the head was off an 08.. Head has been milled and had a valve job so we're in to it for some $$ at this point. Interchange shows 04-05 only. But I did find a thread where someone used an 05 head on a newer block.
I can tell you the 08 head on a 04 block with a 04 head gasket WILL NOT WORK! well it will, but you have a minor oil leak that turns on to a holly cow the car just puked all it's oil when you shut it off! mess... I can not explain why it does this. it just does.
So I pulled the head and did some head scratching and realized the one head has an extra oil passage at the rear middle of the head. This is exactly where the oil shoots out when you shut the car off. (from gasket area between head/block)
Looking at the block, there IS a hole that would line up, just like the front hole.. I was able to lower a 12" 1/4 drive extension down said hole so it seems to go somewhere (down to the sump? I think it's a drain) Seems like the only thing keeping the oil from going where it wants to go is the head gasket. If I used a newer head gasket and put it back together (With new bolts of course) do you think it would work?
I would hate to have to tell the customer "You have a 500 dollar head you can't use, lets spent another 500+ fixing the one that was on the car"
