So I'm trying to swap out my lsj block for an lk9 block that I purchased. I've came across one issue that's puzzling me. The lk9 block has an oil return hole on the side of the block, and i'm sure it has to be plugged, I just don't know what to plug it with. If anyone might have some experience with this swap, and is willing to shed some light I would really appreciate it.

 

thread it with a pipe tap and put a pipe plug in it.

 

Thank you

 

dnt tap the hole you will induce metal into the pan measure the hole and go get a freeze plug and dirve it in the turbo drain back hole
