I recently had a fuel leak, while looking at the top of the engine I found a rubber hose which went to no where. One end was attached to the "Y" pipe which comes off of the intakes on both sides and connects to the turbo. The rubber hose was attached to the top back side of the "Y" pipe. Where does the other end go to? I looked everywhere except where it is supposed to be.
I would appreciate the help!!

 

Look for something like a MAP sensor .That hose could have come off of that sensor.

Also check the waste gate control valve which should have a vacuum hose connected to it.

 

Thanks Ill look into that today. The turbo seems to be not kicking in when I accelerate from a dead stop. I'm going to look at the waste gate first.

 

I checked the waste gate and there is no hose barb connection there, I believe the waste gate works electrically. I,m still searching if you have any ideas please let me know.
Thanks

 

I gave you the wrong info. The info I gave you was for the F series not the E series.
My apologies !

 

That's ok no worries!! Still searching, if you have any thoughts on this let know!

 

The E-vans don't have a waste gate on the turbo. At least my 2000 E-450 7.3l doesn't. You may be looking at the exhaust back pressure valve that's mounted just after the turbo. It closes in cold weather to warm up the engine faster. The actuator in the pedestal is also a common spot for oil leaks.

 

While researching this I agree the "E" series 7.3 doesn't have a waste gate. It is a Exhaust back pressure valve. The original issue I have is there's a rubber hose on the top back of the "Y" pipe which comes off of both sides of the intakes and then connects to the turbo. The rubber hose is connected to the top back side of the "Y" but isn't connected to anything on the other end. I can't figure out where the other end goes. Originally I thought it had to connect to the pedestal for what I thought was a waste gate. So I need to find out where it connects to. If you have any info on that I would appreciate any help!
Thanks

 

Have you found the MAP sensor yet ? There has to be one ! That hose could be off the MAP sensor.

 

I'll find it.
Thanks!
