Most Common Problems with D16Z6 Engine
The D16Z6 engine is generally known for being a reliable and durable engine, but there are a few common issues that can arise with it. Some of these issues include:
Timing belt failure
The timing belt is responsible for keeping the camshaft and crankshaft in sync, and if it breaks or slips, it can cause major engine damage. It’s important to replace the timing belt at the recommended intervals to avoid this issue.
Oil pump failure
The oil pump is responsible for circulating oil throughout the engine, and if it fails, the engine can experience a lack of lubrication and seizing.
Head gasket failure
The head gasket seals the combustion chamber and prevents coolant and oil from mixing. If it fails, it can cause coolant to leak into the oil and cause low compression, resulting in a loss of power and possible engine damage.
Valve stem seals
The valve stem seals are responsible for preventing oil from leaking into the combustion chamber. If they fail, it can cause the engine to burn oil and produce blue smoke from the exhaust.
The distributor is a mechanical component and it can wear out over time. This can cause misfiring and poor performance of the engine.
It’s worth noting that many of these issues can be caused by poor maintenance or neglect, so it’s important to keep up with regular oil changes and other routine maintenance to keep your D16Z6 engine running smoothly.
