2004 BMW 325xi Engine Parts

The Engine Oil Separator is part of the positive crankcase ventilation (PCV) system. This part is typically located on the valve cover and is designed to trap engine oil vapors in the device and return the vapors back into the engine crankcase. When this part becomes plugged oil vapors will be ingested into the intake air system and cause excessive oil consumption and smoke from the tailpipe.

WARNING: This item cannot be returned for a replacement or refund if opened! Manufactured from high-quality materials, the gaskets are designed to provide excellent performance and reliability. Elring gaskets feature specially designed sealing lips. The overall layout of these lips is of particular importance when it comes to ensuring a high-quality seal and long service life. The same applies to the selection of premium-quality raw materials. All-around safety and reliability: Elring oil seals are manufactured for a wide range of applications. Whether they are installed in camshafts, crankshafts or axles, the high-precision seals are guaranteed to offer outstanding performance. Elring oil seals are made from tailor-made elastomer compounds to ensure excellent functionality and a long service life. They are available in various sizes and are supplied with detailed installation instructions.

Pierburg Pump Technology has mapped out a variety of approaches with a view to ensuring dependable lubrication and reliable regulation of the oil supply system under all operating conditions. The aim is to be able to supply pumps that address all the functional requirements while maintaining maximum efficiency and achieving the slightest possible losses. Pierburg Pump Technology’s design department has highly advanced design and simulation tools as well as extensive expertise in the structural analysis of finite elements (static, modal, spectral and fatigue), computer fluid flow dynamics (CFD) and multi-body simulation. Multi-body analysis were introduced to obtain precise information on the factors affecting moving components. The advantage of vane pumps is that they can be simply and continuously controlled over a large adjustment range with constant efficiency. What’s more, they can be positioned both on the crankshaft and in the oil pan. The solution chosen by Pierburg Pump Technology permits the use of various passive and active forms of control.

TRW Engine Components is a recognized developer of valves and valve train components. A wide range of materials and material combinations are used to meet the engineering requirements in the different engine applications. Materials vary from ferritic martensitic steels (intake valves) and austentic CrMn based steels to extreme heat and corrosion resistant Nickel base super alloy for exhaust valves. To improve wear and corrosion resistance, valves can be chromium plated or nitrided. These coatings are used to improve the compatibility of the valve stem surface to the valve guide material. If necessary, exhaust valves (and in some cases also intake valves) can be hard-faced. In hard-facing, a more heat and wear resistant material is welded to form the valve seat. Seat hard-facing extends the valve life significantly.

Product Features:

• OE Quality
• Optimized for strength
• Heat and corrosion resistant
• Chromium plated or nitrided
• Stem optimized to resist wear
