What Makes a 12-Valve Cummins Engine So Popular?
The 12-valve Cummins, specifically the 6BT series, earned its legendary status for good reason.

Unlike their electronically-injected counterparts, these engines are relatively easy to maintain and repair, often with readily available parts. This simplicity makes them a favorite among mechanics and DIY enthusiasts. Their power output, suitable for various applications from trucks to boats, further adds to their appeal.
Where to Find a 12-Valve Cummins Engine for Sale?
Several avenues exist for sourcing a 12-valve Cummins:
