Problems:

Oil leaks

The VH45E engine, especially in older models like the 1992 INFINITI Q45, is prone to oil leaks due to aging gaskets and seals.

Timing chain wear

The timing chain can stretch or wear over time, leading to poor engine performance and potential engine damage if not addressed.

Coolant leaks

The cooling system may develop leaks, often at the water pump or radiator, which can cause overheating if not repaired.

Valve cover gasket failure

Valve cover gaskets can deteriorate, leading to oil seepage and potential contamination of spark plugs.

Fuel injector issues

Fuel injectors can become clogged or fail, causing rough idling, poor fuel economy, and engine misfires.

Intake manifold gasket leaks

The intake manifold gaskets may develop leaks, causing vacuum leaks and poor engine performance.

Ignition coil failure

Ignition coils can fail, leading to misfires, rough running, and difficulty starting the engine.

Mass air flow sensor problems

The mass air flow sensor may become dirty or fail, resulting in incorrect air/fuel mixture and poor engine performance.

Throttle body issues

The throttle body can become dirty or malfunction, affecting acceleration and overall engine responsiveness.

Crankshaft position sensor failure

A failing crankshaft position sensor can lead to stalling, no-start conditions, and erratic engine behavior.
