Common Effects of a Bad Subaru Outback Valve Cover Gasket
A broken Subaru Outback valve cover gasket can cause low-risk problems, which can lead to serious ones if left unfixed. To prevent your valve cover gasket from giving you a headache, take note of the common effects of a broken gasket and learn these simple and useful troubleshooting tips:
If your valve cover gasket gets cracked or damaged, your engine will surely leak oil and leave drops or puddles of it on the ground. Of course, once the oil leaks, the oil levels will surely drop. And if left unattended, your car may lose large amounts of oil. To avoid getting yourself in this scenario, immediately check your valve cover gasket for any sign of wear once you see puddles of oil underneath your Outback. Keep in mind that the oil leaks when your vehicle is parked and the engine turned off. If your valve cover gasket is already cracked, replace it right away to prevent more oil from leaking.
When you see traces of oil on your valve cover gasket, your vehicle may be experiencing oil seepage only. Always remember that oil seepage is different from oil leakage, so there's no urgent need for you to replace your valve cover gasket. Oil seepage usually happens on vehicles that have traveled more than 30,000 miles. And what happens here is that small amount of oil seeps out from the gasket without leaving oil puddles on the ground. The small seep, however, attracts dust and grit than can buildup around the gasket if not cleaned. So if you have dirt buildup there, this means that you just need to monitor your valve cover gasket in case the oil seepage leads to an oil leak. If so, that's the only time you should replace it.
One way to tell if your valve cover gasket already needs to be replaced is when there is gray smoke fuming from the hood. This usually manifests when your vehicle is idling and when the engine heat burns the oil that leaks out from the valve cover gasket. Turning off your engine and replacing the old, worn-out valve cover gasket will solve this problem.
