Common signs include visible oil or fluid spots under the vehicle, a burning oil smell, low oil or transmission fluid levels that recur after topping off, and in some cases a warning light for low oil pressure. Leaking seals and gaskets should be addressed promptly — continued operation with low fluid levels can cause serious mechanical damage.

SIMMERRING® is Freudenberg's name for its radial shaft seal design — a type of rotary seal that prevents fluid leakage around a rotating shaft (like a crankshaft or camshaft) while keeping out contaminants. It's the industry-standard technology many OEMs specify, and Corteco is the only aftermarket channel with access to it.

As engines wear, mating surfaces develop imperfections that a like-for-like original gasket design may not fully compensate for. Corteco engineers incorporate design improvements — such as fully coated elastomer gaskets rather than only localized coating — specifically to seal more effectively against the wear and surface imperfections found in used engines.

An engine mount secures the engine (or transmission) to the vehicle's frame while absorbing vibration, preventing that vibration from transferring into the cabin. A bushing is a smaller vibration-dampening component typically used in suspension and other moving joints to reduce noise and control movement. Both wear out over time and can cause vibration, clunking, or excess movement when worn.

Corteco parts are built to OEM standards for fit and finish. Confirm the exact dimensions, material, and application listed for 49357937 match your vehicle before ordering, since seals and gaskets are precision-fit components where even small dimensional differences can cause leaks.

Some gaskets (like a valve cover gasket) are manageable DIY jobs with basic tools. Others — like crankshaft seals, transmission seals, or anything requiring significant disassembly to access — are more involved and often best left to a certified technician, since improper installation can cause the new seal to fail immediately.
