- [122\-Y8J4E\-11](/bulletins/10125195.md), 2017-12-14, Service bulletin: ENGINE AND ENGINE COOLING:ENGINE:GASOLINE:TURBO/SUPERCHARGER. Information: Debris from the production process can cause the check valves in the oil supply and return lines for the turbocharger to stick open. This allows either too much oil to enter or not enough oil to exit the turbocharger and will overwhelm the seal. Action required: DO NOT replace the turbocharger\(s\). Remove the pressure pipes from the turbochargers to determine which side is stuck open. Replace that line.
