Why you should resurface your cylinder head
Surfacing a cylinder head is an essential step in engine maintenance or repair for several reasons. At M&Y Machine Shop we can resurface your cylinder head with our latest Rottler CNC technology
1. Restore a Flat Sealing Surface
The cylinder head must form a perfect seal with the engine block and the head gasket. Over time, heat, pressure, and wear can warp or damage the head's surface. Surfacing ensures the head is flat, preventing leaks of coolant, oil, or combustion gases.
2. Improve Compression
A warped or uneven cylinder head can cause a loss of compression, leading to poor engine performance, reduced power, and inefficiency. Surfacing restores the head’s ability to maintain proper compression.
3. Fix Damage or Wear
The cylinder head surface may develop pitting, scratches, or other imperfections due to overheating, corrosion, or improper handling. Surfacing removes these defects to provide a clean, smooth surface.
4. Ensure Proper Gasket Seating
A damaged or uneven surface can cause the head gasket to fail prematurely. Surfacing provides a uniform contact area, ensuring the gasket functions as designed and prolonging its life.
5. Address Overheating Issues
Overheating can warp the cylinder head, making resurfacing necessary to restore the proper fit and function. Ignoring this issue can lead to repeated overheating and further damage.
6. Optimize Engine Performance
A properly surfaced cylinder head contributes to efficient combustion and smooth engine operation, improving overall performance and fuel efficiency.
When Should You Surface a Cylinder Head?
- After overheating or a blown head gasket.
- If the head has visible warping or damage.
- As part of an engine rebuild.
- When recommended by a mechanic during routine inspections.
Resurfacing ensures the longevity and reliability of the engine. It’s a precise process and should be performed by a professional machine shop using specialized equipment. We can supply you with high quality AFA head gaskets backed by a 2 year warranty.
