  • Electronic parts: Must be returned with the sealed inspection bag unopened. The clear bag allows full visual inspection before opening. Once opened, electronic parts can only be exchanged for a replacement if defective — no refunds

  • If your part fails within 6 months, we will send a replacement
  • Refunds are only issued if we cannot provide a suitable replacement

Symptoms & Diagnosis

Warning Signs the Cylinder Head is Failing

  • Engine overheating
  • White smoke coming from the exhaust
  • Loss of coolant with no visible leaks
  • Milky or discolored engine oil
  • Rough engine running or misfires
  • Decreased engine power

How to Test If This Part is the Problem

  1. Check for leaks: Look for coolant or oil leaks around the cylinder head.
  2. Perform a compression test: Low compression in one or more cylinders can indicate a cylinder head issue.
  3. Check for combustion leaks: A combustion leak test can identify if combustion gases are leaking into the cooling system.
  4. Inspect the spark plugs: Look for signs of coolant or oil fouling on the spark plugs.
  5. Coolant System Pressure Test: This can reveal leaks in the head gasket or cylinder head itself.

Common Failure Causes for This Part

  • Overheating: Extreme heat can warp or crack the cylinder head.
  • Coolant leaks: Coolant entering the cylinders can cause corrosion and damage.
  • Detonation: Improper combustion can put excessive stress on the cylinder head.
  • Age and wear: Over time, the cylinder head can develop cracks or other damage.
  • Improper installation: Incorrect torque or installation procedures can damage the cylinder head.
