What would cause the 2014 subaru outback 2.5 engine ticking noise?

There are quite a few things that can cause a ticking noise in the 2.5L engine of Your 2014 Subaru Outback, but the most common is a bad oil pump or low oil level. The first thing You should check is Your oil level, and ensure that it's not broken down. Performing an oil change with the manufacturer's recommend oil weight (SAE 0W-20) may help alleviate Your problem. If this doesn't help, You may need to look to Your valve train components, like the lifters, rockers, camshaft, and cam adjuster. You may also have an issue with Your oil pressure sensor, and therefore aren't getting an acceptable oil pressure. Worn lifters are inconvenient, but if Your Outback is high mileage, it's possible that it's a problem You need to learn to live with.
