How to Know If You Need a New Cylinder Head?

Every engine is due for repairs from time to time. Among the most important pieces of most engines is the cylinder head, which, if damaged, can prove increasingly perilous the longer it goes unrepaired. Here are some warning signs and symptoms which may be caused by cylinder head damage.

Weak Engine

Cylinder heads are responsible for containing and directing the internal combustion of an engine’s cylinders, meaning if that ability is hindered, the engine’s efficiency and power may take a hit. This can be seen in lower gas mileage, sluggish acceleration, and difficulty getting up steep inclines.

The Verdict: This is most often among the first signs of a cracked cylinder head, and usually can be repaired if caught in its early stage.

Oil Leakage

Oil is responsible for lubricating the engine’s mechanical parts, including the cylinder head. A cracked cylinder head can cause this to leak, which can be most noticed by a puddle of oil forming on the ground when the vehicle is parked for a long enough time. Such a sign can be a cause for concern, as oil or coolant may also back up into the engine’s internal chambers if the crack is large enough.

The Verdict: Usually, unless oil has backed up into the engine and caused any damage to other parts, a leaking cylinder head can still be repaired and may not require replacement.

Magnaflux Test Cylinder Heads - Clearwater Cylinder HeadCoolant Leakage

Coolant is responsible for cooling the engine, cylinder head, and many other processes. Similarly to oil, a cracked cylinder head can cause coolant to leak. This can be noticed by either a puddle forming beneath the car when parked or an overheating warning lighting up on the vehicle’s dashboard. Coolant can potentially contaminate the oil, and therefore the cylinder head should be repaired as soon as possible.

The Verdict: Unless the coolant has contaminated the oil due to a large enough crack in the cylinder head, at this stage the head can usually be repaired, not replaced.

Engine Misfires

Within an engine’s cylinders, air and gas form a pressurized mixture which explodes upon ignition, creating power. A cracked cylinder head may be unable to create the required atmosphere for proper combustion within those cylinders, leading to failures to combust, or engine misfires. The engine may die repeatedly during use, or fail to start at all.

The Verdict: This is a more severe sign, and usually is indicative of serious damage. It’s always better to take a cylinder head in for repairs or replacement if it starts to show signs of wear, to avoid even higher repair bills when the cylinder head’s failure leads to damages elsewhere in the vehicle.

Smoke

White smoke coming from the engine can indicate a catastrophic failure of the cylinder head, in which exhaust gases are vented directly into the engine space. This is the last stage of total cylinder head failure, and should be avoided by simply going in for repairs at the first signs of damage.

The Verdict: A cylinder head at this stage must be replaced as soon as possible, as it’s either venting exhaust gases or causing coolant to contaminate the oil, neither of which are healthy for any vehicle’s systems.

The cylinder head is one of the most vital parts to your car’s mechanics; your gas-powered car could not work without it. The cylinder head and head gasket sit atop the engine block over the cylinders. The head covers and protects the engine components and creates the correct vacuum for the engine to work. The cylinder head works along with the camshaft, induction and exhaust systems to process the fuel, air, and exhaust to provide your car’s horsepower. Damage, such as, leaks or cracks, in your cylinder head can cause monumental damage to your engine. The correct shape, size, quality, and use of your cylinder head can make all the difference in how your car runs and can help avoid costly engine repairs. To choose the best cylinder head for your specific needs follow these tips for “5 Things to Check Before Buying a Cylinder Head” when choosing a rebuilt, remanufactured, or new cylinder head…

  1. Choose a Compatible Head – Only choose from cylinder heads designed for your car’s specific make, model, year, engine size, and engine enhancements (turbo, supercharger, etc.). Choose a cylinder head metal (aluminum or cast iron) that is compatible with what your engine block is made of as the metals contract and expand at different rates; mismatched cylinder heads are prone to cracking. Choose a cylinder head with right hardware (bolts) for the engine block to ensure your head will fit correctly.
  2. Consider Intake and Exhaust Port Volumes – Bigger intake port volumes are not always necessarily better; depending on engine size and/or application, smaller intake ports may be more suitable. Smaller intake ports often provide better performance for street application as they produce more low-end torque and crisper throttle response, while larger intake ports are more beneficial for larger or higher-revving engines as they allow for more air flow. Choose a good-flowing exhaust port that is the correct size, by comparing to stock exhaust port volume and valve size for your specific engine.
  3. Determine the Combustion Chamber Size and Design needed for Your Engine – Choose a combustion chamber size that raises the compression ratio to maximize your engines efficiency, while matching the components of your specific engine, such as, bore, stroke, head gasket, and piston shape, as well as, deck clearance and ring location.
  4. Consider Application – Whether you are using your car for street or off-road driving or drag, circle track, or road racing, deciding the primary application for your engine is important is picking out the cylinder head to best fit your needs. Valve lift, air flow, and duration can be altered to provide the best performance for your car’s specific application.
