-
Cylinder Head & Block Separation: Disassemble engine to access crankshaft and cylinders.
-
Piston Extraction: Remove old pistons and rings carefully to avoid cylinder damage.
-
Cylinder Inspection: Measure and hone cylinders to specification; verify correct bore size.
-
Ring Installation: Install new rings onto each piston, ensuring correct orientation and gap.
-
Piston Installation: Fit pistons into cylinders with ring compressor; hand-tighten connecting rod bolts.
-
Torque & Timing: Torque all fasteners to OEM spec; set ignition timing and fuel injection.
-
Engine Test: Prime engine, check for leaks, perform cold and hot start tests.
⚠️ Critical: Verify your exact engine variant and cylinder bore size before purchasing. Incorrect piston size will cause severe engine damage. If unsure, submit your VIN or engine block photographs to our support team before checkout.
