Porsche Crankshaft Seal - DPH 021105247A

Product Information

The engine crankshaft seal, also known as the main seal, is a critical component that prevents oil from leaking out of the engine around the crankshaft. Your crankshaft seal is positioned where the crankshaft exits the engine block, typically at the front or rear of the engine. It creates a tight barrier between the rotating crankshaft and the stationary engine parts, preventing oil from leaking at this point.

The crankshaft seal helps maintain the proper oil pressure inside the engine, which is essential for lubricating the internal components and ensuring smooth engine operation.

• Oil leaks: One of the most noticeable signs is oil leaking from the front or rear of the engine. This can be seen around the crankshaft pulley (front seal) or near the transmission area (rear seal)
• Burning oil smell: If the oil leak from the seal reaches hot engine components, you may notice a burning oil smell
• Check engine light: In some cases, oil pressure may drop if the crankshaft seal leaks significantly, triggering the check engine light

About Rein

Founded in 2007, CRP Automotive introduced the Rein Automotive line of OE-quality replacement parts to the aftermarket. And in just two short years, Rein Automotive has become very popular among both warehouse distributors and professional repair technicians. Rein is the German word for “pure”, and has come to be synonymous with quality in the automotive aftermarket. A true dealer alternative.

The Rein brand includes a growing number of “better than OE” parts for selected applications. These parts address known weaknesses and premature failures of factory parts. Many of these replacement and service solutions have been developed with the help of our Innovation Council, a hand-picked group of experienced professional repair technicians and shop owners throughout North America.

All Rein Automotive OE-quality parts are backed by the CRP Automotive standard, and are backed with a ISO 9001:2015 quality management system certification. Each year, CRP Automotive ships thousands of Rein Automotive brand products. And with widespread NAFTA market distribution through strategically placed warehouses in Cranbury, New Jersey and Puebla, Mexico - OE-quality products like Rein Automotive are delivered to customers both faster and more cost-effectively than ever before.

In 2017 Rein partnered with FCP Euro in competing a W204 C300 AER car for the 2017 season. The partnership focused FCP Euro to dive deep into the Rein catalog offering, and hundreds of new products were added and integrated into our catalog. Hundreds of new packages were created not only using the full part pine up of Rein products, but also the entire family of CRP products like Pentosin.

Rein is also an innovative brand, winning numerous trade awards — including multiple new product innovation awards at the annual AAPEX trade show.
