When it comes to Ford 7.3 Gas vs 6.7 Diesel comparison, many people may prefer the Ford 7.3L gas engines over the 6.7L Power Stroke diesel engine.
Each one of these engines has its own set of advantages and disadvantages.
We’re going to start this off with a bang. In terms of performance and hauling, the 6.7L diesel is the best option.
Nevertheless, the 6.7L is a $10,000+ engine choice, and not everyone requires more than the 6.7L does.
All the advantages and disadvantages of each vehicle are discussed here, as well as typical issues and possible fixes.
What is Ford 6.7L Powerstroke V8 Turbo Diesel Engine?
One of the most powerful V8 turbocharged diesel engines on the market is the 6.7L Powerstroke engine.
In 2008, Ford Motor Company started developing a revolutionary diesel engine for their Ford Super Duty in-house trucks, starting with a blank slate.
The Scorpion was a codename for this new product during its development, and the 6.7L Powerstroke engine was already in place when Ford unveiled it in 2011.
As an alternative to International Navistar’s 6.4L Power Stroke, Ford developed the 6.7L Powerstroke. After working together as partners for almost 30 years.
6.7L Power Stroke’s cylinder block is comprised of compressed graphite iron, which is lighter and stronger than cast iron (CGI).
6.7L Powerstroke’s nodular iron six-bolt head caps are likewise found on the deep-skirt block. Additionally, to the CGI material, the block layout and the CGI material save a substantial amount of weight.
Steel crankshaft, Mahle powder-metal cracked-cap connect rods, and Federal-Mogul cast aluminum cylinders are also included in the 6.7L Power stroke.
The end caps of the linking rods have been rotated by 45 degrees to improve their strength.
Piston cooling jets were installed in the engine to reduce the temperature of the piston and the combustion chamber.
Engine longevity benefits from this. Tupy, an American foundry company, makes all 6.7L blocks.

6.7 Powerstroke Reliability
Because of its longevity and low maintenance requirements, the 6.7L Powerstroke engine has been in production for many years.
If you follow Ford’s recommended service intervals, this engine should be able to reach 300,000miles with no problems.
The fuel pump needs air and contaminants-free fuel, and the fuel filters of both engines must be changed before or at the manufacturer’s recommended interval.
Failures with the 6.7L emissions system are the largest roadblock to achieving good mileage.
All the emissions-control systems, including the EGR coolers, EGR valves, SCR systems and/or DPF, and different sensors, can require repairs, ranging from simple to catastrophic.
In the oil fields in Texas, and along North American pipelines like the great 7.3L, this engine has proven itself time and time again to be tough and reliable.
Common issues of 6.7 L Powerstroke & Solution
01. Diluting the oil with water
To avoid this problem in the future, make it a habit to check your oil. Replace the oil and filter as soon as you realize you’ve exceeded your maximum oil capacity.
The advice given in the owner’s manual is incorrect. Instead, get your 6.4L Power stroke’s oil and filter changed every 5,000 miles.
02. Radiators leaking
Other than changing the radiator, there isn’t a solution to this problem. The best course of action is to replace your factory radiator even if it has not yet failed.
03. Failure of the Injection Pump
Fuel system metal pollution has the potential to destroy numerous other components. For many, pump difficulties have necessitated the complete replacement of the gasoline system.
Injectors, fuel lines, and regulators may all need to be replaced on the 6.7L Power Stroke.
04. An assortment of pipes with holes in them
If your up-pipes are cracked, your only choice is to change them. If you’re in the market for a new exhaust system, there are several high-quality aftermarket options available.
05. Problems with Fuel-Water Separators
Draining the fuel separator/OEM Water regularly is the best approach to avoid fuel system failure. The more often, the better.
06. Engine Oil Cooler Clogged
Due to its design, the 6.7L oil cooler cannot be cleaned. Instead, you’ll need to get rid of it entirely.
You can either use an alternative engine oil cooler or a Ford Original engine oil cooler to fix the issue for another 50-75,000 miles.
What is 7.3L Powerstroke Engine?
The 7.3L Powerstroke diesel engine was a Ford game-changer in the mid-1990s. It was developed by Navistar and released in 1994.
It took five years for the initial 210 horsepower and 425 pound-feet of torque produced by the electronically/hydraulically fueled (poppet-valve and HPOP injectors) fixed-geometry turbocharged engine to be replaced by the 275 hp and 525 pound-feet of torque produced by the final 7.3L model year in 2003 after a five-year run of upgrades and upgrades.
Ford switched from the 7.3L to the 6.0L Navistar diesel in the middle of 2003.
Designed with four-valve heads, enhanced electronic fueling (higher pressure and spool-valve injectors) as well as an EGR system, the current Power Stroke engine was stronger (325hp/ 560 lb-ft of torque) while complying with more stringent emissions regulations that were expected in 2004 and beyond (lower NOx).
