Product Description

This complete cylinder head assembly is designed for Mazda RF / RF-T / RF-CX / R2 2.0L and 2.2L SOHC diesel engines, widely used in Mazda Bongo, E-series vans, 323, Capella, Ford Laser, and Kia Besta. Fully assembled and pressure tested, it is a ready-to-install replacement for cracked or worn cylinder heads in both naturally aspirated and turbocharged applications.

Crafted from premium aluminum alloy and machined to OEM specifications, this head ensures long service life, perfect sealing, and efficient combustion for high-performance and fuel economy.

Common Engine Issues Resolved

ProblemCauseOur Solution
Cylinder head cracksOverheating / casting fatigueNew casting, pressure-tested
Valve noise or tickingWorn rockers or lash adjustersNew camshaft, rocker assembly
Oil in coolant / coolant lossCracked oil/coolant passagesLeak-tested head with isolated circuits
Compression lossWarped deck or worn valvesCNC-machined deck, new valves & seats
Excessive smokeValve seal failure or poor compressionNew stem seals & seating surfaces

Installation Tips

  1. Clean block surface and inspect for flatness.
  2. Use correct torque sequence and values (varies by engine generation).
  3. Align timing belt or gear properly.
  4. Bleed coolant system to prevent hot spots.
  5. Change engine oil and prime the lubrication system before startup.
  6. If solid tappets are used, check valve clearance after engine warm-up.
