finding codes #401 and #0068. Help please.

Had Ford in Corning Ca. run a diag yesterday ad these codes came up. What I am experiencing is a loss of power and a loud "wooshing of air" sound coming into the cab under increased rpms.

Would you think that there could be a hole in the turbo hoses? What else could it be with this rush of air sound?

Could it be a P006b instead of 8??? EGR insufficient flow and loud whooshing of air screams y-pipe leak to me, but check all your turbo pipes. If it is a y-pipe you might see smoke coming from the back of the motor when you rev it.

The y-pipe is the whole pipe assy that #1 in this pic is pointing to not just the expansion joints: http://www.backglass.org/duncan/ps60...l/ps60_011.jpg however it is usually one of the expansion joints that fails.

P0068 must be a new code for a diesel so I'll have to let someone else weigh in on that. The Ford master list says it isn't used on a diesel and P006B is an exhaust related code for a diesel.
