25 января 2022 г. 7 Possible Causes Of Low Oil Pressure In Your Heavy Diesel Engine |
So, you notice your oil pressure is low. Your automatic response might be to have your oil pump looked at, or to replace it altogether.
A lot of times this might solve your problem. But what happens if you get a new pump and your pressure is still low?
There are quite a few other reasons that can lead to low oil pressure. As you evaluate your particular problem, you might want to consider some of the following as possible causes of your issue.
7 POSSIBLE CAUSES OF LOW OIL PRESSURE IN YOUR DIESEL ENGINE
1. FAULTY OIL PRESSURE GAUGE
If you've replaced your oil pump, recently changed your oil, and ensured there were no other issues in the system, there is a chance your oil pressure gauge is malfunctioning. You can have your oil pressure tested, and, if it comes back normal, a sensor replacement should solve your issue.
2. PLUGGED OIL FILTER
If your filter is plugged by dirt, debris, or other contaminants, the proper amount of oil won't be able to flow through your engine, decreasing oil pressure. Replacing the clogged filter with a new, clean one should take care of the issue.
3. WORN BEARINGS
Old, worn bearings can create oil pressure issues as well. As your bearings wear, clearance space increases, which increases the amount of oil used. This, in turn, decreases the overall oil pressure.
4. CONTAMINATED OIL
Contaminants in your oil (coolant, fuel, air, etc.) can alter the oil viscosity and how it flows through your engine. If this seems to be what's causing your engine problems, you'll need to identify the source of the contamination to solve the problem.
5. NOT ENOUGH OIL
Make sure you've checked the oil levels in your engine. If your pressure is low, you might simply have to put in more oil.
If your engine is consuming large amounts of oil, you may have a larger engine problem.
6. IMPROPER INSTALL
Even if your oil pump is new, if it wasn't installed correctly, you'll still be experiencing problems.
We have an earlier post that details various ways a poorly installed oil pump can cause you trouble. If you're experiencing low pressure after installing a new pump, verify that it has been installed correctly.
7. ENGINE AGE
Similar to worn bearings, an older engine will consume more oil, leading to a decrease in oil pressure. In some cases, you'll need to completely rebuild your engine.
EXPERIENCING LOW OIL PRESSURE FOLLOWING AN ENGINE REBUILD
Sometimes, we hear operators complain that they're still experiencing poor oil pressure after rebuilding their engine. Ideally, a rebuild would help fix this, but a few factors might prevent it.
Improper break-in, for instance, could cause low oil pressure. Similarly, not following proper oil change procedures could negatively impact your oil pressure.

10 января 2022 г. 4 Signs You Need To Replace Your Diesel Engine Cylinder Head And Causes |
What Is The Function Of A Cylinder Head?
Your cylinder head is a critical part of your diesel engine. Along with the head gasket, it creates the combustion chamber that allows the combustion process to occur properly.
It also lets air in and exhaust out. Coolant and fuel both flow through your cylinder head. This makes its health vitally important to proper engine function.
3 Issues That Can Cause Cylinder Head Failure
You might notice several key symptoms of cylinder head problems, including high oil consumption, bad fuel mileage, and engine overheating.
1. CRACKS
Overheating causes one of the most common cylinder head issues—cracking. These cracks often occur between the valves, but not always.
2. OIL LEAKS
Sometimes, if your engine has high mileage and the valve stems or valve guides are worn out, oil can begin to leak down into the combustion chamber. Improperly sealing valves will negatively affect your combustion, and you won't get the efficiency you're looking for in your engine.
3. CONTAMINATION
Cracks through to your fuel system can allow fuel to infiltrate your engine oil. This contamination can lead to other major engine issues.
These problems, if left unaddressed, could mean serious trouble for your engine. You might even experience a total engine failure.
Often, the best solution is to replace your cylinder head. You have a few options when it comes to replacing your cylinder head. Highway & Heavy Parts can help you find the best solution for your diesel engine problems.
4 COMMON CYLINDER HEAD FAILURE SYMPTOMS
1. OVERHEATING
As we mentioned, cylinder head cracking is a common issue, and it can lead to other problems. Excessive heat causes the head to expand and contract, which leads to cracking. Depending on the model, the head is sometimes made of a different material, which can make this problem worse.
If you have a crack in your diesel engine's cylinder head, it could reach your coolant passages, allowing compression gases from the combustion cycle to fill those passages. This displaces the coolant, which causes the head to overheat in certain areas.
This overheating tends to crack the head even worse.
2. POOR FUEL ECONOMY
You might also notice a decrease in your diesel engine's fuel economy. This could be caused by improperly sealing valves, leading to incorrect pressure in the combustion cycle.
In cases like this, you'd be putting significantly more fuel in the engine to get the same amount of power.
3. EXCESSIVE OIL CONSUMPTION
Sometimes the valves and valve guides will wear, or seals will come off or get dislodged (knocked or forced out of position), allowing oil to enter the intake or exhaust ports, which causes high oil consumption.
4. WHITE SMOKE
White smoke can also be an indicator of cylinder head problems. In extreme situations, white smoke can come from the diesel engine itself, indicating that coolant has contaminated your oil due to a cracked or damaged head.
It could also indicate exhaust gases escaping through the cylinder head, which signals the need to replace it.
It's important not to ignore these warning signs. While these symptoms might indicate issues other than your cylinder head, don't assume it's not your head. Be sure to evaluate the health of your head to try and prevent catastrophic engine failure from costing you even more time and money.

27 декабря 2021 г. When Does Your Cummins N14 Need A Rebuild? N14 Inframe Kit Overview |
We know that rebuilding your engine is a time consuming and expensive process. And that's not even mentioning the profits you lose when your engine is out of commission.
WHEN DOES YOUR N14 NEED A REBUILD?
Like with any engine, there are a few things that indicate it's time for a rebuild. You might notice oil consumption, lack of power, or you just might have a million miles on the engine.
There are some things to watch out for on the N14, specifically. This engine was first produced in 1991, and they've been one of the most popular engines for years.
Some of these engines now have 20-30 years on them, and we're starting to see some common problems pop up.
FIRE RINGS ON YOUR N14
With the N14, a lot of times we see a blown head gasket causing issues. It's important to know, though, that in many cases you can't just replace the head gasket and call it good. It's likely that the fire rings are also bad.
A fire ring is a small groove machined into the cylinder head around each combustion chamber. A stainless steel ring is inserted into the groove.
This ring acts as an additional seal around the combustion chamber, and ensures greater reliability when operating under stressful conditions.
CHECK THE CLEARANCES AROUND YOUR BEARINGS
When you're overhauling your N14, it's important to check the clearances around your bearings. If you don't, you can not only lose the overhaul you just did, but you also risk failure in your crankshaft and your block.
You can check these clearances by using a plastic gauge, which is a small piece of plastic that you lay across the bearing journal. Then, you bolt everything together with the bearing on the crank.
That piece of plastic is going to squish down when you tighten everything. When you take it apart, you measure how wide the plastic squished—the wider it is, the less clearance there is.
If you don't measure your oil clearance, you run the risk of putting the wrong size bearings in your engine. This can lead to excessive oil clearance and problems in your N14 down the road.
REPLACE YOUR PISTON COOLING NOZZLES DURING AN OVERHAUL
While you're overhauling your engine, it's also a good idea to take a look at your piston cooling nozzles. We recommend that you replace them every time.
They're made out of plastic and are fairly inexpensive components, but they're critical in keeping the bottom of the piston cool.
If you have a failure with a broken piston nozzle, you might notice low oil pressure or an overheating piston.

25 декабря 2021 г. When Can I Reuse My Cylinder Head Bolts? How To Clean, And Inspect |
Head bolts might seem like a minor or unimportant part, but without them, combustion wouldn't be possible and your diesel engine wouldn't work. They hold your cylinder head to the engine block and help the head gasket to seal properly.
When you take apart or replace these components, you shouldn't ignore your head bolts. Doing so could increase your risk of serious failure down the road.
The initial temptation might be to just reuse your old head bolts. I mean, how bad could it really be? At times, this might be completely fine, but as we'll go on to discuss, it may not be in your engine's best interest to put old bolts back in.
So, just how do you tell when it's safe to reuse your bolts? We're taking you through when you might want to consider replacing your head bolts.
INSPECTING AND CLEANING YOUR HEAD BOLTS
After you remove your head bolts, you'll want to give them a solid inspection before deciding whether or not to reuse them.
WHAT TO LOOK FOR WHEN INSPECTING YOUR HEAD BOLTS
First, check for any obvious signs of wear or damage to your bolts. Especially pay attention to the threads. Worn or damaged bolts stand a much higher chance of failure.
Check the length of your bolts as well—if your bolts have been too stretched, they will have lengthened. They will likely display some visible distortions because of this.
You should also always check the length of new bolts, as depending on your engine model, different bolt holes require different length bolts. The wrong length bolts won't clamp down with the correct force, which affects the seal and allows for leaks.
THINGS TO KEEP IN MIND WHEN CLEANING YOUR HEAD BOLTS
The bolts and bolt holes need to be completely cleaned before reinstallation to ensure proper clamp and torque measurements. Lubricate the bolts in engine oil as part of the cleaning process.
3 SIGNS YOUR HEAD BOLTS CAN'T BE REUSED
1. DAMAGED HEAD BOLTS
Bolts with any signs of damage, no matter how slight, should never be reused. Not only will the bolts eventually fail, but when they do, there is the potential for them to cause damage to your cylinder head. This results in a much more expensive repair than simply replacing the bolts in the first place.
2. STRETCHED HEAD BOLTS
Bolts are designed to stretch as you torque them into place, and when you remove them, they snap back to their original position. Because of this, many standard head bolts are okay to use more than once, as long as they have not been stretched past their spring back point. Once this occurs, they should no longer be used in the engine, as they won't clamp properly.
3. TORQUE-TO-YIELD HEAD BOLTS
Torque-to-Yield bolts (TTY), should not be used more than once, because, by design, they are stretched past their spring back point the first time they are installed. This allows for a more even load, and is especially useful for some of the gaskets and cylinder heads made out of less forgiving materials.
Because they are stretched out the first time, though, it's highly likely that they will fail if reinstalled, due to overstretching and improper clamping. If you're unsure whether or not you have TTY bolts in your engine, check the specifications in your engine manual, which should tell you.
PROBLEMS WITH REUSING HEAD BOLTS
An old head bolt that doesn't allow for proper clamping can lead to leaks in your engine. Coolant will be able to leak through the bolt hole and cause more issues for your engine.
One of the largest issues with reusing old head bolts that are past their prime is the risk it creates for your gasket. If a head bolt breaks or fails to maintain torque, you can blow the head gasket, which in turn leads to a whole host of other issues for your engine—and an expensive repair.
Similarly, you won't be able to install worn or damaged bolts correctly, which impacts how the gasket is installed. A poorly installed gasket leaks and can damage other engine components.
All in all, it's often best to install new head bolts when you work on your cylinder head or head gasket, unless you can be absolutely sure the age and condition of your current ones. It will save you headaches and cash in the future.

15 декабря 2021 г. What Caused A Crack In My Diesel Engine Cylinder Head? |
We know how frustrating it can be when your cylinder head cracks. You're losing coolant, have compression in your cooling system, or seeing excessive smoke, and you're looking at lost time and money and an expensive repair.
One of the keys to saving yourself this frustration is trying to prevent cylinder head failure before it happens.
In this post, we're taking you through why your cylinder head may be cracked and how you can help prevent it in the future. We're here to help you get back up and running, fast, and prevent a repeat failure.
WHAT CAUSED A CRACK IN MY CYLINDER HEAD?
In a failed cylinder head, the most common symptom people see is a cracked head.
If your head is cracked, you're probably wondering what caused it. Traditionally, a cracked cylinder head is a result of temperature and pressure.
In other words, extreme temperatures and pressure inside the cylinder produce an environment that the cylinder head can't withstand. The material will begin to weaken over time and you'll get a crack or multiple cracks in your cylinder head.
YOUR VALVES CAN SUFFER TOO
Your valves suffer in this same environment, they'll likely end up stretching, breaking, or a common failure is a chordal fracture. We've also seen situations where valves “grow”.
This extreme temperature causes the stretch in the valve and reduces the clearance between the valves and rocker arms. You'll see a reduction in overhead lash and accelerated wear.
By putting in stronger or more durable valves like inconel valves you can help solve the valve problem, but it won't necessarily stop the cylinder head from cracking. You'll be treating a symptom rather than the cause of the problem.
If you have liner protrusion problems or a blown head gasket, for example, you'll still end up with a crack in the head. You're not going to get around that unless you fix the base engine problem.
It is very unlikely that a crack in the cylinder head is a result of defective material. There is more likely an underlying issue that needs to be addressed to help the life of your head.
ENGINE DELETIONS CAN CAUSE CYLINDER HEAD ISSUES
If you've changed your emissions status or horsepower, you've probably affected your engine timing, which might be the cause of cracking in your cylinder head.
Engine deletions can create an environment that makes the head more susceptible to cracking, especially with twin turbos. If these engines have been deleted, you're more likely to see cylinder head cracks from the higher compression ratio pistons, timing and fuel air ratios that are now out of balance.
It's important to note that engine deletions are illegal, and we don't participate in or condone the practice. But, if you're running into problems with your cylinder head on a deleted engine, there's a few things to note.
HOW DELETIONS AFFECT YOUR ENGINE
First, people will commonly choose to delete their engines because of problems with the aftertreatment system and poor fuel mileage. And while these problems might be fixed after the deletion, it does create other problems in your engine.
It can inadvertently cause the cracks in your cylinder head because the cylinder pressures are raised. This means the timing is off and the temperatures are hotter.
PREVENTING CYLINDER HEAD CRACKS
We don't handle the calibrations with the timing on deleted engines, but there are some things you can do to help prevent your cylinder head from cracking.
First, you can reduce the cylinder pressure and temperature. There are multiple ways to accomplish this, but if you want to stop the head cracks and gasket leaks this needs to be done.
It's also become common, on 3406's and C15's, to change the horsepower calibrations on them to try and get all the horsepower out of them as possible. Sometimes, though, not everything works together and you might start to see issues.
OTHER ISSUES THAT CAN CAUSE CYLINDER HEADS TO OVERHEAT
You might be having issues because the counterbores weren't cut, the liner protrusion is off, and you blow a head gasket. This causes compression in the cooling system resulting in air pockets, which overheat the cylinder head.
Driving conditions can also cause cracks in your cylinder head. If you're driving through mountainous areas, you have long pulls that put the engine under a duty cycle for a longer period of time.
This can be counteracted by the driver, how they shift, and what RPM ranges they run, keeping boost a little lower and RPMs a bit higher. Just because you don’t have to shift to crest a hill doesn't mean you shouldn’t downshift.
Many drivers have the desire to not downshift as they go over a hill. This will bring the engine RPMs down and result in higher engine temperatures.
The faster the piston spins, the more air comes in the engine, and the more exhaust and heat goes out. Faster RPMs mean you're getting more exhaust out of the engine, which lowers the temperature. This will help your cylinder head last longer.
One unique thing about diagnosing cylinder head issues is that you can't really measure the cylinder pressure and temperature. Unlike your oil pressure, there isn't a gauge that tells you what your cylinder pressure is.
So, it's really a hidden enemy, causing problems every day. Boost pressure is an indicator, so sometimes less is better!
