Cylinder Heads: HHP Buying Guide

When's the last time you thought about your cylinder head? If you've noticed a decrease in fuel economy or your engine has been overheating, you might want to take a look at your head—it could be time to replace it.

 

Cylinder Heads Explained

Your cylinder head serves a vital function in your engine. Without it, combustion couldn't occur. Not only does the cylinder head let air in and exhaust out, both coolant and fuel move through it. Damage to the cylinder head can cause severe problems for the rest of your engine, so it's important to diagnose and address issues as soon as you can.

Signs You Need to Replace Your Cylinder Head

There are a few symptoms you can look for that might indicate an issue with your cylinder head:

High Oil Consumption

Worn or broken valve stems or guides can cause a poor seal. This allows oil to enter the intake or exhaust ports, leading to high oil consumption.

Poor Fuel Economy

Similarly, improperly sealing valves affect the pressure during combustion. This causes more fuel to be used to achieve the same amount of power.

Overheating

Overheating leads to cracks in the cylinder head. These cracks spell trouble for the rest of your engine. If left unaddressed, the cracks could worsen and allow combustion gas to infiltrate the coolant, or for coolant to contaminate your oil.

White Smoke

White smoke can point to a cylinder head issue. Sometimes, it indicates oil contamination caused by a cracked head, especially if the smoke is coming from under the hood.

 

What to Look for When Purchasing a Cylinder Head

Not sure what you're looking for? Here's some things you might consider:

Remanufactured or New

One decision you'll have to make is whether you want a new cylinder head or a remanufactured one. Our remanned cylinder heads are professionally rebuilt, with any wear or cracks repaired to run like new, all the while saving you cash. And we've done the research! We know which cylinder heads can be sold remanufactured and which are better sold new. For more information on the remanufacturing process, check out our past blog, Rebuilt Cylinder Head vs. Remanufactured Cylinder Head.

While a new cylinder head will cost you a little more money, you'll also know that there haven’t been any previous issues with it. A new cylinder head from us includes all new components as well, so you're getting the additional peace of mind knowing that you should be ready to run for another million miles.

Engine Type

It's important that you purchase a cylinder head that is compatible with your engine model, otherwise you'll find yourself facing even more down time as you look for the proper part. Having your engine serial number handy while you shop can help with this.

OEM vs. Aftermarket Cylinder Heads

Why buy quality aftermarket over OEM? Let us show you!

No Used Components!

With a cylinder head from HHP, whether remanufactured or new, you'll get all brand new components—valves, guides, springs, keepers, retainers, injector cups, and cam bearings (if they're used). Most places, including the OEM, will try to reuse as many parts as possible. We put new components in our heads because we know that's what you need to keep your engine running for another million miles. Why would you trust the health of your engine to used parts? We don't think you should have to!

Better Prices

Do you like to spend more than you have to? If you're like us, the answer is no. With a quality aftermarket supplier like HHP, you'll get parts that meet or exceed OEM specifications, for a lot less money. But if you go with the OEM, you'll be paying as much as 50% more for the same part. And, for the most part, with OEM parts, you're paying for their name on the box more than anything.

Great Quality

Don't believe everything you hear about the poor quality of aftermarket parts. Some aftermarket suppliers may stuff scrap metal in a box and pass it off as a cylinder head, but that's not something you'll have to worry about with HHP. We spend the time to make sure you get the best possible quality parts—sometimes even exceeding OEM standards.

In fact, a lot of times the manufacturers whose parts we sell also make the same parts for the OEMs. That's right, the OEMs don't even make their own parts any more. So while you may think you're getting genuine OEM parts, those no longer actually exist. With a quality aftermarket supplier like HHP, you'll get the same caliber parts for less. And, our warranties are often double what the OEMs offer.


Questions for Your Mechanic

If you've noticed any of the signs of cylinder head problems, you probably want to talk to your mechanic. Consider asking the following questions to better understand what exactly is going wrong in your engine.

  • Am I better off purchasing a new or remanned head, or can mine be rebuilt?
  • Could my poor fuel economy or high oil consumption be caused by an issue with my cylinder head?
  • Do you see any signs of oil or coolant contamination?
  • What could have caused the damage to my cylinder head?

You can also feel free to give us a call at 844-215-3406 to speak with one of our certified techs regarding any questions you have about cylinder heads, or any of the other diesel engine parts we sell.
