Review on 🔧 Genuine Subaru 803916010 Gasket, 1 Pack for Enhanced SEO by Alejandro Dabney

Compressible washer is required for the oil drain plug and is used to relieve stress on the oil pan and drain plug threads. When you squeeze the crush washer, the washer takes the load, not the threads. If you reuse a crush disk, compression cannot occur and therefore thread tension will occur. Pay attention to the thickness of the used crush washer compared to the new one. Failure to do so could result in loss of oil, plugs or (in the worst case) engine.
