I recently took the turbo out to swap in a batmowheel and I fired the truck up after installation. After about 5 minutes I shut the truck off when I noticed a huge amount of oil under the truck. I am almost 100% sure it is leaking from the turbo drain tube since the oil was coming down from both sides from the top of the transmission. I did replace the drain gasket. I’m just hoping someone else has had this problem and found a solution. I’m going to be pulling the down pipe and up pipes again tomarrow to check.
