Enginetech timing cover seals are precision-fit replacement seals engineered to prevent oil leakage at the front crankshaft seal location. Built on over 40 years of engine rebuilding expertise, each seal is designed around the specific engine family it serves - seal material, lip geometry, and dimensional specifications are matched to the crankshaft snout diameter and timing cover bore of that exact application. Seal material selection matters: Nitrile seals are standard for metal covers, Polyacrylate seals deliver improved high-temperature performance and flexibility for plastic covers, Viton seals handle extreme heat and chemical exposure, and PTFE-lip seals with wear sleeves are engineered for high-mileage applications where crankshaft surface wear is a concern. Always verify fitment by year, make, model, VIN code, and engine displacement before ordering - and confirm your timing cover type (metal or plastic) where noted.
