How to Drain Engine Oil?

Engine Oil Won't Drain

If your engine oil is refusing to drain properly, there are a few methods you can try. One is pumping some of the oil out through your dipstick hole; another involves taking out the filter and allowing some excess oil to drain before refilling with new oil.

If that doesn’t work, you could try using a drain plug to pull the oil out. However, this method may be more complex and require some expertise.

If you decide to do this, make sure the oil pan is placed underneath the drain plug so all of the oil can drain into it. You may use an approved catch pan or simply a bucket, but make sure it’s large enough so that it can hold all of the oil from your car.

What Cause Engine Oil Not to Drain?

Your car’s oil is the lifeblood of its engine. Not only does it lubricate moving parts and keep things running cool inside the engine, but low oil levels can lead to serious issues as well.

One of the most frequent reasons your engine oil won’t drain is a faulty gasket or seal. Your car has various types of gaskets, such as those in the valve cover and oil pan, that form a seal around your engine to prevent leaks.

Most often, the problem lies with a gasket that has worn out or been damaged. This can happen when driving over bumps and potholes that scrape against it, or when your engine is heavily used and its parts undergo prolonged temperature exposure.

Another possible reason your engine oil may not drain properly is if your engine drain plug isn’t tightened properly. This issue can easily be rectified; just make sure not to overtighten when taking it out of the oil pan.

Let’s not forget that, oil filter and drain plug are essential elements in your vehicle’s engine, so it’s essential that they both remain in optimal condition.
