Cylinder Head Resurfacing Cost

a. Importance of Cylinder Head Maintenance

Over time, the movement of a car engine’s components, particularly the pistons, generates friction. This friction can wear down the cylinders, eventually leading to engine failure.

b. Cost of Cylinder Head Resurfacing

Replacing cylinder heads regularly can prevent this catastrophe and keep the engine within normal operating parameters. Cylinder head resurfacing costs vary depending on the engine’s build and can potentially reach up to $700. For a typical “shave and seal” procedure, involving cleaning, resurfacing the deck, and reseating all valves, the cost might range between $150 and $200. Additional charges may apply if parts like valves, seats, or springs need replacement.

c. Camshafts’ Role in Resurfacing

When taking the engine head for milling and a valve job, it’s necessary to bring the camshafts. During milling, properly tensioning the cams to specified torque ensures a flat head. Neglecting this step might lead to slight casting adjustments after flattening, potentially requiring adjustments when reinstalling the cams.

Maintaining cylinder heads is crucial for engine longevity and performance. Understanding the process involved in resurfacing and valve jobs can help ensure optimal engine functionality and prevent costly issues in the future.

Signs That Your Car’s Cylinder Heads Need Resurfacing:

Car engine cylinder heads are generally quite durable. You don’t need to be worried about them because regular engine maintenance will keep them smooth and leak-free.

Expert Insight

Cars Direct estimates that a four-cylinder engine rebuild will cost between $400 and $500. As the number of cylinders increases, the price tag goes up. A six-cylinder vehicle will cost between $500 and $600, while an eight-cylinder will cost you between $600 to $700.

The usual procedure for milling the engine cylinder heads is part a larger repair known as an engine rebuild. The engine block’s lower section is removed, cleaned and inspected. The cylinder heads are then resurfaced so that the rings and pistons can be properly seated within the cylinder’s body.

Resurfacing of Cylinder Heads is Required

Wear and tear are signs you should have your cylinder heads resurfaced. The cylinder head can crack due to engine overheating. This can also happen if there is too much coolant in the cooling system. Coolant can boil and cause head damage.

If you notice oil or coolant leakage, or if your engine is not running as it should, it is a good idea to have your cylinder head checked by a professional.

Are you unsure how to tell if your cylinder heads need to be resurfaced? These are the top three signs that your cylinder head needs to be resurfaced. Also, what should you do if you’ve experienced them?

  1. Head Gasket Failure. You run the risk that an uneven surface could compromise the head gasket sealing between the cylinder head and the head. This can lead to head gasket failure. The cylinder head can be resurfaced to create a secure, even seal between the components.
  2. Uneven Surface Finish. For your cylinder head to function properly, it must have an even surface. You may experience problems with other parts or the engine if your cylinder head has an uneven surface. To determine if the cylinder head is in the right range, you can use a comparator gauge.
