Common VT365 Problems and What to Check When Buying Used
The VT365's known weak points are the EGR cooler, the oil cooler, the head gaskets and head bolts (studs are the common upgrade), the HEUI high-pressure oil pump and injector sticking, the FICM, and VGT turbo sticking. A properly updated example is regarded as dependable, so condition and prior repairs matter more than the year. Every VT365 we sell is run-tested before it ships.
