6.0 y pipe leaking

6.0 y pipe leaking how much power am I losing and how hard to repair?

Depending on how bad the leak is will determine how much power loss.

To replace, remove turbo, loosen up-pipe at exhaust manifold, remove bolts from up-pipe to y-pipe, remove bolts from y-pipe to exhaust manifold. Remove old y-pipe, place new y-pipe in place and re-install bolts and leave loose to allow movement and adjustment for when you install turbo. After turbo is installed and y-pipe to turbo has made a tight seal, bolt the turbo to pedestal, then tighten down the y-pipe to exhaust manifold and up-pipe connections.

Where is it leaking? Have you checked the connections?

If the turbo has been on for a while and the leak recently started, I would kind of doubt that its leaking at a connection, probably a blown bellow.

I have a good used one sitting in my garage if you need/want. A lot cheaper than a new one

Hello and thank for your info and interest in my predicament, everything is tight. From outside the truck it all sounds good but inside it sounds like there’s a chopper under the hood.
It’s leaving black soot on the firewall and an exhaust smell in the cab. The Tech at the dealership thinks it’s a crack in the tubing
The turbo had been hanging up a lot when pulling, and I read on a post to start driving it a lot harder than I usually do to maybe clean it out but this Tech also said you had to pull the motor to fix it, and at another dealer the Tech said that you drop the transmission. Its camping season, so time to start pulling my trailer and need the ponies. Thanks.

Pulling the motor???Dropping the trans??? for a y-pipe??
That's just ridiculous. I just did an EGR delete in my driveway pulled everything apart including turbo and y-pipe and passenger up-pipe, not to bad a job at all. Do it yourself if you have the time and tools

Appreciation to all! This is why I joined the forum; I would rather ask a stupid question than make stupid a mistake. I am no dummy but they have stuffed this 6slow so far up under the dash if you told I needed a leprechaun to climb up to get a to bolt I my believe you.
