Is Your Subaru a Victim of Gasket Problems? Find Out which Model Year Are Affected Now!

If you own a Subaru car, you might have heard of the infamous gasket issue that plagues many of their models. The issue has been prevalent for quite some time now and can become a significant problem for the vehicle’s engine if not addressed early on. In this article, we will dive into the details of the Subaru gasket problem and which years of Subaru cars are most affected.

What is a gasket issue in Subaru, and why does it occur?

A head gasket is a seal located between the engine block and the cylinder head that prevents coolant and oil from mixing. The gasket itself is made of layered steel and coated with a rubber-like material. In Subaru cars, the gasket issue occurs when the seal wears off, leading to the coolant and oil mixing and causing engine misfire or overheating.

This happens due to the flat-four engine configuration in most Subaru cars, where the weight of the engine adds stress to the head gasket, which can cause it to fail over time.

What are the signs of having a gasket problem in Subaru cars?

Several signs can indicate that your Subaru car is experiencing a gasket issue. The most common signs include:

  • Overheating engine
  • Engine misfire
  • White smoke coming from the exhaust
  • Milky substance in the oil tank
  • Low coolant levels without any visible leaks
