Ok after trying some different search phrases I found some good info. After reading all that, I think I'm gonna wait till I get everything put together and figure out where to put the oil drain. I guess some guys have found that the drain in the block is too high for the lower turbo and causes problems. Makes more sense now. This is a fresh built engine and I really dont want to take any chances of getting metal in it by drilling, tapping, or punching anything. What are you guys using to punch a hole in it anyways? Thanks!
