Turbo Leak

I've looked and looked for some insight on this...

Just got done putting studs in, prior to I didn't have any issues other than a HPO leak, replaced all o-rings and turbo has been taken on and off several times for egr delete, HPO system tests and so forth. We did get the heads resurfaced and put everything back together. Now I have a leak under the hood that sounds like I have my a/c on high while its under boost. I unplug the vgt and it goes away. I've checked where the exhaust manifolds mount to up/y pipes and both have mounted correctly and are as tight as I can get them with the stubby wrench and 3/8 ratchet due to tight quarters. I have a perfect seal from the y-pipe to the turbo and my exhaust is the same. I can't find this DA@# leak... any ideas?? it's definitely from the back of the motor and not the intercoolers and so forth, but just to be sure I'm going to rule out the CAC system with a leak test this weekend.

It only builds to 20# of boost under WOT and tuned so idk....im about to take it to a stealership and tell them to fix the dang thang and pay the money. I'll take the KY with me...just about fed up with it.

Re: Turbo Leak

It could be the y pipe bellows just rotted out I just replaced mine and that cleared up my leak in a hurry make sure there is no black residue around them if there is that could be the culprit, Id recommend strokers unlimited for a new on really great quality and great price about 150 for a ceramic coated one

Ok, I found the leak. It was actually a cracked intake manifold gasket. I replaced it and in the process broke the nipple off of the MAP sensor. I tried to redneck repair it until I could get to FORD on mon to get a new one but now my truck won't boost at all with no leaks, i can hear the turbo spooling just no vgt pressure, I tried to relearn the vgt cycle with no avail and my truck wont get over about 30 mph and is throwing cylinder 2,3,8 ckt low codes.

Does this sound like a typical MAP sensor failure?

Circuit low codes are related to the FICM and you might also have a cylinder 5 low error as well... Those are all common to the middle connector on the FICM and probably just wasn't seated correctly. Get that middle connector snapped back onto the FICM and see what she does. Keep us posted.

That's a turbo code, so it's unlikely FICM related. Double check your VGT solenoid wiring (two wires plugged into the front of the turbo on the passenger side). Sometimes that connector get brittle and can break or it could indicate your turbo vanes are stuck and need to be cleaned.
