Stopped for a coffee tonight left my truck running and noticed it had a knock. Sounds like it is coming from the area in which the turbo is. Still builds boost, no oil coming out exhaust, not smoking. Nursed it home and noticed sound progresses with rpm and now has a squeaky sound added to it. when I shut it off the sound continuess to come from the turbo area as the turbo spools down. Truck has 6200 miles on it, spartan warhammer added , dpf delete, and egr delete done at 4000 miles. No check engine lights or codes thrown. Going to take to dealer on monday, my guess is the turbo is on its way out
