Turbochargers offer a significant boost to the performance of small engines, allowing you to get “more bang for your buck.” However, they need a number of components in order to work correctly. The oil return hose ensures that your turbo stays lubricated during operation and that the used oil will return to the engine, where it will be filtered and recirculated. Though some oil return hoses are made of stainless steel or braided stainless steel, most are made of heat resistant rubber. The oil return hose is subject to temperatures well above 600 degrees fahrenheit during normal operation, and this figure is even higher during hard runs. Because temperature-induced wear and tear on the hose is significant, the hose will harden, dry and crack over time. They can be difficult to remove, and brittle hoses can break. If this happens during operation, oil will spray out of the hose, and the turbocharger (not to mention the engine) will be damaged from insufficient lubrication.
For both your engine and your turbocharger to operate correctly, they must be supplied with a constant stream of engine oil. If the engine oil return hose is damaged, serious consequences will result. Work with one of our expert mechanics, capable of keeping an eye on all of the hoses and belts under the hood during normal maintenance, to replace those hoses well before any issues become serious.
Without an operational oil return hose, both your turbocharger and engine will be compromised in the worst-case scenario. The best prevention method is to work with our experienced mechanics, who will provide ongoing maintenance. By conducting regular inspections, the mechanic will detect any signs of degradation on the oil return hose and replace it if necessary. If your hose is cracked, bulging or otherwise damaged, we recommend having it replaced immediately.
