Sorry guys, just got back into town about an hour ago. The oil drain line for the turbo is an area i must have overlooked and never even considered, I'll have to take a look and see about a solution tomorrow. Haven't quite finished the tach, but I did get it wired to a point where I think it should work. I'll post a couple of pics for that in the AM as well. However I won;t be able to say for sure whether or not it works until it's running. I also reused the Mitsubishi oil pressure sensor, but you need a fitting for it to thread into the diesel block. More pics and stuff tomorrow.
