Removal and Installation: Removal

WARNING: This page is about a different car, the 2018 Nissan Titan XD. However, it is still accessible from the selected car via links, so may be relevant.

WARNING:

Diesel fuel and diesel fuel vapor is flammable. To avoid risk of fire or burns, never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.
The fuel system (fuel pump, high-pressure fuel lines, fuel rail, injectors) contain very high pressure fuel. To avoid the risk of personal injury or fire:
- Never loosen any fittings while the engine is running.
- Wait at least 10 minutes after shutting down the engine before loosening any fittings in the high-pressure fuel system to allow pressure to decrease to a lower level.
- Wear appropriate eye protection and protective equipment as high-pressure fuel spray can penetrate the skin.
- Never smoke or allow sparks or flames (such as pilot lights, electrical switches, or welding equipment) in the work area. Never allow diesel fuel to spill onto a hot exhaust manifold which can cause a fire.

CAUTION: Do not reuse the front cover gaskets.
NOTE:
- Check for gasket material on the cylinder block or heads.
- If there is a lack of tension on the fuel pump or camshaft timing chains after removing the front cover, this does not indicate chain tensioner failure. The chain tensioners are fed oil pressure to keep tension on the chains. During removal, the chains may not be under full tension, this does not warrant replacement.
Drain all engine coolant and oil from front cover and clean after removal.
CAUTION: If replacement of the front cover is necessary, the oil filter bypass valve must be installed new. Oil filter bypass valve does not come with new front cover and is available separately. If engine is operated without the oil filter bypass valve, engine damage could result.
