Symptoms of Faulty Head Gasket

  1. When the head gasket is developing problems, there are slight gaps that let oil leak underneath the engine. If you discover oil is leaking from your Subaru car, that might be a symptom that the oil gasket is getting faulty.
  2. The head gasket is a passageway for coolant to flow appropriately. When there is no more coolant in the vehicle, it makes the engine hot thereby causing the temperature gauge on the dashboard to go up. It can make the engine overheat which will cause a problem for the Subaru.
  3. When you go for a long drive, more heat will be produced in the vehicle. Since there isn’t any coolant regulating because of the faulty head gasket, there will be more friction and heat.

A final thought

If you notice some symptoms that your Subaru head gasket is damaged, you need to take it to a professional mechanic. It needs a high level of expertise to repair, and unless you have the skills required, you may actually make it worse.
