Removal
WARNING: Do not smoke, carry lighted tobacco or have an open flame of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Before working on or disconnecting any of the fuel tubes or fuel system components, relieve the fuel system pressure to prevent accidental spraying of fuel. Fuel in the fuel system remains under high pressure, even when the engine is not running. Failure to follow this instruction may result in serious personal injury.
WARNING: Do not carry personal electronic devices such as cell phones, pagers or audio equipment of any type when working on or near any fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Always disconnect the battery ground cable at the battery when working on an evaporative emission (EVAP) system or fuel-related component. Highly flammable mixtures are always present and may be ignited. Failure to follow these instructions may result in serious personal injury.
WARNING: Clean all fuel residue from the engine compartment. If not removed, fuel residue may ignite when the engine is returned to operation. Failure to follow this instruction may result in serious personal injury.
NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including any material created while cleaning gasket surfaces that enters the oil passages, coolant passages or the oil pan, may cause engine failure.
NOTE: If the cylinder head is replaced, a new secondary timing chain tensioner will need to be installed.
1.Release the fuel pressure.
2.Remove the RH turbocharger.
3.Remove the RH camshafts. For additional information, refer to Camshaft RH.
4.Remove the fuel rail.
5.NOTICE: Do not use power tools to remove the bolts or damage to the RH primary timing chain guide may occur.
Remove the 2 bolts and the RH upper primary timing chain guide.
6.Remove the nut, bolt and the Camshaft Position (CMP) heat shield.
7.Disconnect the 2 RH CMP sensor and the Cylinder Head Temperature (CHT) sensor electrical connectors. Remove the ground stud bolt.
8.Remove the 2 bolts and the 2 RH CMP sensors. Remove and discard CHT sensor.
9.Remove the bolt and position aside the ground strap.
10.NOTE: If the components are to be reinstalled, they must be installed in the same positions. Mark the components for installation into their original positions.
Remove the valve tappets form the cylinder head.
11.Inspect the valve tappets.
12.Remove and discard the M6 bolt.
13.NOTICE: Place clean, lint-free shop towels over exposed engine cavities. Carefully remove the towels so foreign material is not dropped into the engine. Any foreign material (including any material created while cleaning gasket surfaces) that enters the oil passages or the oil pan, may cause engine failure
NOTICE: Aluminum surfaces are soft and may be scratched easily. Never place the cylinder head gasket surface, unprotected, on a bench surface.
NOTE: The cylinder head bolts must be discarded and new bolts must be installed. They are a tighten-to-yield design and cannot be reused.
Remove and discard the 8 bolts from the cylinder head.
Remove the cylinder head.
Discard the cylinder head gasket.
14.NOTICE: Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These tools cause scratches and gouges that make leak paths. Use a plastic scraping tool to remove all traces of the head gasket.
NOTE: Observe all warnings or cautions and follow all application directions contained on the packaging of the silicone gasket remover and the metal surface prep.
NOTE: If there is no residual gasket material present, metal surface prep can be used to clean and prepare the surfaces.
Clean the cylinder head-to-cylinder block mating surfaces of both the cylinder heads and the cylinder block in the following sequence.
1.Remove any large deposits of silicone or gasket material with a plastic scraper.
2.Apply silicone gasket remover, following package directions, and allow to set for several minutes.
3.Remove the silicone gasket remover with a plastic scraper. A second application of silicone gasket remover may be required if residual traces of silicone or gasket material remain.
4.Apply metal surface prep, following package directions, to remove any remaining traces of oil or coolant and to prepare the surfaces to bond with the new gasket. Do not attempt to make the metal shiny. Some staining of the metal surfaces is normal
15Support the cylinder head on a bench with the head gasket side up. Check the cylinder head distortion and the cylinder block distortion.
