The Absolute Worst Used Diesel Trucks Ever Made

worst diesel trucks

These are the rigs to avoid if you’re looking for a used diesel truck.
Everyone’s seen a Ford with a bumper sticker of Calvin Hobbes taking a whiz on the Cummins emblem. Diesel truck owners are a proud bunch that swears their trucks are the best. But not all vehicles are created equal. There are some real junkers out there– even if the owners don’t want to admit it. Before you get conned into buying someone else’s compression-ignited nightmare, check out this list. These are the rigs you’ll want to avoid truck challenges if you’re looking for a used diesel truck.

Chevy and GMC C/K pickup 5.7 L (1978-1981)

GM’s 5.7 L diesel can be found in your grandpa’s Oldsmobile, and it can also be found in Chevy and GMC pickup trucks. The 5.7 L diesel was a gas 5.7 L converted into diesel. This sounds like a bad idea– and it is. All kinds of problems plague this old oil burner, including faulty head bolts. Weak torque to yield bolts paired with an extremely high compression ratio, cause the cylinder heads to lift off the block. And levitating cylinder heads are bad business. Sure, vintage diesel trucks can be cool, but stay away from 5.7 L diesel-equipped rigs.

Chevy and GMC C/K pickup 6.2 L (1982-1993)

After the 5.7 L diesel debacle, GM realized it should get out of the diesel-building business. So, it hired engine maker, Detroit, to build its next diesel power plant. The result was the uneconomical and anemic 6.2 L diesel. Although it’s the size of a VW bug, the huge naturally aspirated engine makes very little power. The original 6.2 L makes 130 HP, which is only 40 more ponies than a modern Smart car. The 6.2 L also tends to dump oil from its rear main seal– a costly repair that involves removing the transmission.

Chevy and GMC C/K pickup 6.5 L (1994-2001)

Most 6.5 L engines are turbocharged, which gives them an edge over the feeble 6.2 L. Even so, the Detroit built 6.5 L can’t compete with the same era Cummins and Powerstroke engines. While the other diesel engines were being fitted with direct injection, the 6.5 L hobbled along with indirect injection. At its best, the 6.5 L makes 180 HP and 360 lb-ft.

Compare that with a Powerstroke-equipped Ford of the same vintage, making up to 275 HP, and it’s easy to see the GM 6.5 L is outclassed.
Besides the glaring lack of power, the 6.5 L is riddled with mechanical problems. One of the most common issues is the failure of the pump-mounted driver. This unit is used to supply power to the fuel solenoid. When it fails, it can cause all kinds of problems. From a no-start condition to stalling. The lesson; save your pennies and buy a Duramax.

Ford Super Duty 6.0 L (2003-2007)

Introduced mid-2003, the Ford 6.0 L turbo is by far the worst modern diesel engine and really bad rig truck. It’s so bad that Navistar (Powerstroke’s parent company) and Ford had a legal battle over it. The list of issues ranges from head gasket problems to catastrophic fuel system failures. And the best part is, most of these problems require removal of the cab for repair. Once a vehicle has been ravaged to the point of having its crew cab removed, do you want it? Probably not. Buy a Ford with a 7.3 L Powerstroke, instead.
