6.0 Power Stroke High Pressure Oil Pump Symptoms
If you are an owner of a 6.0 Power Stroke engine, it is important to know the warning signs that your high pressure oil pump may need replacement. When your 6.0 power stroke diesel engine fails due to a failed high pressure oil pump, you will experience many different symptoms including: excessive smoke from the exhaust, low oil pressure or no oil pressure at all, turbocharger failure and more.
For some owners who have had their truck for years and never knew about this issue until they experienced these problems firsthand, it can be extremely frustrating and costly because by then the vehicle’s value has decreased significantly. Keep reading the article and if you notice any of these symptoms on your vehicle we recommend having an experienced mechanic inspect your vehicle immediately.
What is an Oil Pump?
The oil pump is a critical component in the 6.0 Power Stroke diesel engine. The pump circulates engine oil throughout the engine and components, providing lubrication and cooling. If the pump fails, it can result in serious engine damage.
An oil pump is a mechanical device used to circulate engine oil. It is located in the engine block and is driven by the crankshaft. The oil pump circulates oil throughout the engine, carrying heat away from the combustion chambers and returning it to the crankcase. This prevents the engine from seizing and allows it to run smoothly. An oil pump failure can result in extensive damage to the engine.
The high pressure oil pump is located on the drivers side of the engine, just in front of the 6.0 power stroke turbocharger. The high pressure oil pump is responsible for supplying pressurized oil to the entire engine, including the fuel system and turbocharger. It is important to keep this pump in good working condition, as it can affect the performance and longevity of the entire engine.
If the oil pump fails, the engine may experience loss of power, poor performance, or even complete failure. You may also notice a loss of oil pressure, black smoke from the exhaust, or an increase in fuel consumption.

The high pressure oil pump is a critical component of your Ford 6.0 diesel engine, and should never be neglected.
Ford 6.0 diesel high pressure oil pump problems can cause a number of symptoms. If your truck is exhibiting any of the following, it may be time to consider having the pump replaced.
6.0 Power Stroke high pressure oil pump symptoms
So, what are some symptoms of a bad or failing high pressure oil pump?
If you have a 6.0 Power Stroke and are experiencing any of the following symptoms, then you are likely having problems with your high pressure oil pump:
- Your 6.0 liter diesel will not start, even after repeated attempts to do so. You may hear clicks or contact the starter for longer periods of time before it finally starts up. If you have recently replaced the batteries in your truck, then this might be causing issues because your batteries are unable to hold a charge.
- If you turn your engine off after it has been running, then the engine will die as soon as you release your foot from the accelerator pedal. This means that there is not enough pressure coming from the HPOP to keep oil moving through your injectors and into your cylinders.
- You notice that your engine is idling at a very high RPM, but the truck will hardly move when you push down on the accelerator pedal.
- If your 6.0 liter diesel continues to drive for longer periods of time when no one is touching the accelerator pedal, then it is likely that your HPOP has failed or is leaking oil into your cylinders.
- After driving for an extended period of time without issue, you turn the key off and restart your engine within 30 seconds. This time, however; it will not start up because there is no pressure in the system.
- The check engine light comes on and stays on after having recently replaced your high pressure oil pump. It may also be accompanied by other trouble codes such as P0299 or P0300.
- You notice that your oil pressure reading is very low, but your truck will continue to run for extended periods of time.
- Smoke or steam comes out from under the hood in large amounts when you are driving. This means that there is a high amount of pressure in your system and oil is being pushed through your injectors at rapid speeds, which leads to it burning off.
- Your engine makes loud ticking sounds while it is idling, especially when you have recently turned the key off after driving it. The noise may seem excessive if you have an aftermarket turbocharger installed on your diesel engine. Thrashing sounds coming from the top end are also a result of high pressure oil pumps that are failing.
- Your truck has also been consuming large amounts of diesel exhaust fluid (DEF). This is because if your HPOP fails, then it will cause the injectors to become misaligned and spray fuel everywhere throughout the engine bay. The carbon and soot left behind by this combusting fuel will quickly clog up and ruin your emissions system which requires DEF to be injected into the system in order for you to pass an emissions test.
If you are experiencing any of these symptoms, then it is important to get your truck to a qualified mechanic as soon as possible for diagnosis and repair. The high pressure oil pump is a vital component in your 6.0 liter diesel engine and should be kept in good condition at all times. Failing to do so can lead to costly repairs and down time.
How to find high pressure oil leak 6.0 Power Stroke
The 6.0 Power Stroke is a great engine and has a lot of potential if properly maintained. On the other hand, it can turn into a money pit quickly if it develops an oil leak or some other issue that causes you to have to pull the engine apart just to fix it – such as a high pressure oil pump failure.
The first step in finding a high pressure oil leak is to check the engine oil level. If it’s low, there’s a good chance you have a leak somewhere in the system. However, this isn’t always the case – so don’t rule out other potential causes of low oil pressure just yet.
After checking the oil level, start your truck and let it run for a few minutes. Then, stop the engine and check the dipstick again. If the level has gone down since you last checked it, there’s a good chance you have an oil leak.
Now that you’ve narrowed it down to a high pressure oil leak, it’s time to start inspecting some of the most likely culprits. The first place to start is by checking the hoses and fittings that connect the high pressure oil pump to the engine. If any of these are loose or cracked, they could be leaking oil.
Another common source of high pressure oil leaks is the oil filter. If the gasket on the filter is damaged or worn out, it can allow oil to seep out. Be sure to check the seal on the filter housing as well – if it’s damaged, it could be causing a leak.
Finally, take a look at the high pressure oil pump itself. If it’s damaged or leaking, you’ll need to replace it.
By following these tips, you should be able to locate the source of your high pressure oil leak 6. Power Stroke and get your truck back up and running in no time.
How to replace a pressure oil pump Ford 6.0 Power Stroke
Here’s what you’ll need:
- A socket set
- Breaker bar
- Torque wrench
- New HPOP
- A new gasket for the old pump
- Oil pan to catch oil
- Thread sealant tape
- An extra person to assist with oil removal and reinstallation
- Drain the oil from the engine by removing the drain plug on the side of the engine. It is located near the bell housing and has a magnet attached to it in order to catch any metal shavings that may be in your oil pan. Be sure that this plug does not have any other foreign material stuck in it such as a washer or by catching something solid like a bolt (which shouldn’t be there anyway).
- Assuming you are putting in an upgraded/modified pump, do not use Ford’s special TTY bolts on the 6.0 Powerstroke high pressure oil pump repair kit; install 4 3/8″ socket head cap screws – grade 8 – 1/4 20 thread with Loctite 271. 3 of these screws go into the pump housing and 1 goes into the timing gear cover.
- Remove the serpentine belt by releasing the tensioner and sliding the belt off of the pulleys.
- Disconnect the oil cooler lines by loosening the hose clamps and pulling them off of the fittings – there is one on each side of the engine.
- Disconnect the wiring harness from the HPOP (high pressure oil pump) by pressing in on the locking tab and pulling it free from its connector – there is one on each side of engine.
- Remove 4 bolts that hold the high pressure oil pump to the timing gear cover – 2 at front and 2 at rear using a ratcheting box end wrench. Also remove the bolts that hold the oil pan to the engine block.
- Remove the high pressure oil pump in one of two ways:
- Place a shallow pan under the HPOP, loosen inlet fitting (female thread) and outlet fitting (male thread). Turn each retainer knob 1/4 turn clockwise and pull assembly out of housing – this is for when you are replacing only one gasket. Do not mix up which gasket goes where if both are being replaced!
- Place shallow pan under HPOP and then use air or electric impact gun to remove oil pump – this is for when you are reusing either or both gets. The reason that it is easier to remove the pump with the air or electric impact gun is that you can get a better grip on the pump.
- Install new high pressure oil pump using either installation method in step 7. Be sure to install new o-rings on fittings and apply a light coat of oil to them before installing – these will help prevent leaks.
- Reinstall HPOP in reverse order of removal and be sure to torque all bolts – except the 4 TTY bolts from Ford’s special kit – to specs listed in the 6.0 Powerstroke shop manual.
- Reconnect wiring harnesses, oil cooler lines, serpentine belt, and battery cables. Start engine and check for leaks.
