Ford 7.8 Diesel Engine Overview
The Ford 7.8L diesels used in Ford medium duty vehicles are based on the naturally aspirated engines that New Holland Machine Company made in the 1960s.
After Ford bought New Holland, they would use a turbocharged version of the 7.8L in their Ford B-Series buses and other medium-duty vehicles.
The official names of the engines are the Ford-New Holland 6.6L and the Ford-New Holland 7.8L. People often call them “Brazilian” Ford diesels because they were made at New Holland factories in Brazil.
Both of Ford’s inline 6-cylinder diesels were well received, and the engines have been praised for being durable and reliable, even if they aren’t very powerful.
The 6.6L could be ordered with up to 170 horsepower and 402 lb-ft of torque. The 7.8L, on the other hand, could be ordered with 240 horsepower and 606 lb-ft of torque.
The bore-to-stroke ratio of 6.6L engines was square, while 7.8L engines had the same bore but a longer stroke. The Brazilian Fords are not very fast and won’t win any races.
But many people will say that they are good engines that did the jobs they were made for and were on par with other engines in terms of how long they last and how reliable they are.

Ford-New Holland 7.8 History
New Holland has a long history and strong roots in the farming business. In 1895, the company began in New Holland, Pennsylvania.
In 1986, Ford bought the company for real and turned it into Ford New Holland Inc. Since the 1960s, New Holland had been making 6.6L and 7.8L diesel engines that ran on air.
They kept making these engines after the Ford-New Holland brand, but they changed them to be turbodiesels. The engines were made at New Holland plants in Brazil, which is how they got the name “Ford Brazilian diesel.”
In medium-duty trucks, Ford also sold engines made by Cummins, Caterpillar, and Detroit in addition to engines made by Ford-New Holland.
After 1994, the 6.6 and 7.8 diesels were replaced with engines that were more powerful and more advanced.
Ford 7.8 Diesel Engine Problems
The Ford 6.6 and 7.8 diesel engines have been around for more than 28–35 years. Few of them are still in use, and when something is that old, it can start to break down.
So, most of the problems with the Brazilian 6.6L and 7.8L diesels have to do with their age and the fact that they are hard to find. In the next few paragraphs, we’ll talk about the following:
- Complex maintenance / costly parts
- Oil Leaks
Overall, these diesel engines have a good reputation and are thought to be durable and reliable. We haven’t seen too many big or common problems with the Ford 7.8L. But because they are old, they will need a little extra care to keep going (or farm).
1) 6.6 & 7.8 Complex Maintenance / Costly Parts
Another common complaint about these diesels is that they have more than one part. Some people complain that maintenance and repairs are harder to do than with other diesel engines that are similar.
One problem is that the Brazilian 7.8 don’t have wet sleeves, which makes rebuilding a bit harder. If not, it might be harder to get to and replace certain parts.
The next part was about how these engines were made in Brazil for a short amount of time. When it comes to engines like the 5.9 Cummins, parts can be harder to find. But there were a lot of Ford 7.8L diesels on the road, so it shouldn’t be too hard to find replacement parts.
Still, the engines are more than 25 years old, which makes it harder to find parts. There are still some parts that you can find online at places like JenSales. If not, local junkyards might have some spare parts or engines.
2) Ford 6.6 and 7.8 Diesel Oil Leaks
Last, the Ford 6.6 diesel and 7.8 diesel both leak oil. Twenty years ago, it might not have been fair to say that oil leaks were a common problem.
There aren’t really any problems with the way the car was made that cause oil leaks. But because these engines are old, there are probably a lot of worn gaskets, o-rings, seals, etc. that can leak.
Oil leaks seem to happen most often where the oil pan gasket is. Also check the oil cooler for the Ford 6.6 diesel, as these can sometimes leak too.
In the end, this section was meant to show that these older engines need a little bit more care. Rubber parts, gaskets, seals, and other similar parts tend to break down as they get older and get more miles on them.
