I broke this green and red vacuum? hose related to the turbo. I assume I need new unit since it sure doesn't look repairable. Can anyone tell me the part name? I cannot find it in schematics on Ebay.

 

Wastegate solenoid. The part number can be found by searching here. I am on my phone and cannot look for you, otherwise I would get it for you.

 

I'd just disconnect it, but that's just me.

 

Thx guys. Found it. F81Z-6C673-AA, solenoid.

You can't leave this unplugged can you?

 

Yep, mine was disconnected when I got it and many disconnect it. The wastegate releases boots in the event it gets too high but...I don't believe that boost can get too high.

 

No kidding?! I wouldn't dare do that with my gasoline turbo vehicles. Is this unique to diesel engines or just the 7.3l?

 

Mine has been plugged laying in the valley since my kid was 7. She's 28 now. Haven't seen it for awhile. Fill your holes and drive it.

7.3's are dogged. They don't ever see boost that would require a drop unless your VERY heavily modified. In fact, all the rednecks I run with just reach in and pull it and leave them unplugged. I see them often, still driving the same rigs.

Denny, it doesn't generate a check engine light?

 

No check engine light unless you exceed 22 lbs of boost or so. I don't know about other engines but this one it doesn't seem to be essential. I'd plug up the holes though.

 

Plug the green line where it connects at the intake boot and remove the lines. The is also a connection at the intake spider. Remove and plug that nipple. Leave the solenoid valve wires plugged in or you will get a check engine light.

 

Thx much guys. Much obliged..

 

 

 

A gasser being over boosted can run lean and blow, diesels don't care about air/fuel ratios for the most part. Gassers always operate in a fairly tight range of A/F ratio which is why they need something to throttle down the air flow, a throttle body or carburetor butterflies. Diesels don't use a throttle body, the air intake is usually wide open. They idle really lean and power/RPM is controlled solely by controlling the fuel. It would probably be impossible to damage a diesel engine by disabling the waste gate. For sure a 7.3 can't be damaged by it and I don't know of any that can.

 

Boost numbers north of 40psi required head studs. Unless you are running something like 238/100 injectors or larger, you aren't going to get there. Your stock turbo won't do it anyway. About the most you'll ever get from your stock turbo is 28psi.
