A power system, comprising a turbocharger, an oil sump, a supply passage, a return passage, and a turbocharger bypass passage. The supply passage is positioned fluidly between the turbocharger and the oil sump and is configured to supply oil to the turbocharger. The return passage is positioned fluidly between the turbocharger and the oil sump and is configured to return oil from the turbocharger to the oil sump. The turbocharger bypass passage is positioned fluidly between the supply passage and the return passage. The turbocharger bypass passage comprises a valve that is configured to be in a closed positioned when the turbocharger is in a normal operating mode, and in an open position when the turbocharger is in a failure mode.

1. A power system, comprising: a turbocharger;an oil sump;a supply passage positioned fluidly between the turbocharger and the oil sump, the supply passage configured to supply oil to the turbocharger;a return passage positioned fluidly between the turbocharger and oil sump, the return passage being configured to return oil from the turbocharger to the oil sump; anda turbocharger bypass passage positioned fluidly between the supply passage and the return passage, the turbocharger bypass passage comprising a valve, the valve being configured to be in a closed positioned when the turbocharger is in a normal operating mode, and the valve being configured to be in an open position when the turbocharger is in a failure mode. 2. The power system of claim 1, wherein the turbocharger and the valve are positioned in parallel relative to one another. 3. The power system of claim 1, wherein the turbocharger is positioned such that, when the turbocharger is in the failure mode, gravity urges the oil to flow away from the turbocharger and towards the turbocharger bypass passage and the return passage. 4. The power system of claim 1, wherein the supply passage comprises an oil filter. 5. The power system of claim 1, wherein the supply passage and the return passage and the turbocharger bypass passage are all stainless steel, braided hoses. 6. The power system of claim 1, wherein there is not a valve positioned in the supply passage. 7. The power system of claim 1, wherein the turbocharger bypass passage and the supply passage and the return passage are all rigid tubes. 8. The power system of claim 1, wherein the turbocharger bypass passage is welded to the supply passage and to the return passage. 9. The power system of claim 1, wherein the valve is a check valve, and the check valve is configured to prevent the oil from flowing away from the return passage and towards the supply passage. 10. The power system of claim 9, wherein the check valve is electronically actuated in response to a signal indicating when the turbocharger is in the normal operating mode and to a signal indicating when the turbocharger is in the failure mode. 11. The power system of claim 10, wherein the check valve comprises an electrical connection, the check valve comprises a first side and a second side, the turbocharger bypass passage comprises a first portion and a second portion, the first portion is positioned between the supply passage and the first side of the check valve, the second portion is positioned between the return passage and the second side of the check valve, the electrical connection is positioned on the second side of the check valve. 12. A method for a power system, the power system comprising a turbocharger; an oil sump; a supply passage positioned fluidly between the turbocharger and the oil sump, the supply passage configured to supply oil to the turbocharger; a return passage positioned fluidly between the turbocharger and oil sump, the return passage being configured to return oil from the turbocharger to the oil sump; and a turbocharger bypass passage positioned fluidly between the supply passage and the return passage, the turbocharger bypass passage comprising a valve, the method comprising: detecting when the turbocharger is in a failure mode;producing a signal when the turbocharger is in the failure mode; andopening the valve in response to the signal. 13. The method of claim 12, comprising shutting down the power system after opening the valve in response to the signal.
