Known issues
Most frequent / serious themes first; amber labels mark year gates.
Cylinder head gasket failure
Often reported
This engine absolutely cannot tolerate overheating, and its thermostat regularly leaks through the housing. Therefore, replacing the gasket with surface grinding is a common procedure.
Valve burnout
Often reported
Another frequent problem is burnout of one or more exhaust valves. The cause is usually oil carbon deposits on the valve head or wear of the valve guide.
Capricious sensors
Often reported
The electrical system causes a lot of trouble in this engine: crankshaft and camshaft position sensors fail, and the oil pressure sensor often leaks.
Other shortcomings
Often reported
Also, there are constant complaints online about malfunctions in the fuel vapor recovery system, as well as the short lifespan of engine mounts, spark plug wires, and the balance shaft chain.
