Bmw 335Xi Engine Oil Filter Covers

Bmw 335Xi Engine oil filter covers

Engine oil filter covers for your Bmw 335Xi start at $40.95. We stock 3 options from URO and Dorman. The oil filter cover seals and houses the oil filter cartridge, keeping pressurized oil directed through the filter and away from leaks. A cracked or stripped cover causes oil loss, pressure drops, and engine damage if ignored.

Signs your Bmw 335Xi needs a new engine oil filter cover

  • Visible oil puddle or wet residue directly beneath the oil filter housing area
  • Oil level drops between changes with no obvious external leak elsewhere
  • Oil pressure warning light illuminates at idle or under load
  • Burning oil smell from the engine bay caused by oil dripping onto hot exhaust components
  • Cracked, chipped, or cross-threaded plastic visible on the cover itself
  • Oil filter cartridge fails to seat or seal properly even with a new filter installed

Which engine oil filter cover should you buy for your Bmw 335Xi?

The main decision is material and fitment precision. OEM-spec covers match factory thread pitch and sealing surfaces exactly, while aftermarket options vary in durability and include or exclude the drain valve and O-ring. Confirm whether your Bmw 335Xi uses a top-mount cartridge-style housing or a spin-on cap before ordering.

Replacing the engine oil filter cover on a Bmw 335Xi

Easy⏱ 30–60 minutesOil filter cap wrench (correct size for your Bmw 335Xi)Torque wrenchDrain pan and shop ragsPick or O-ring removal toolClean lint-free cloth for wiping the housing seat

Drain or partially drain the engine oil, then use the correct cap wrench to remove the old cover and discard the used filter cartridge and O-ring. Clean the housing seating surface thoroughly, install the new O-ring with a light coat of fresh oil, seat the new filter cartridge, and thread the new cover on by hand before finishing with a torque wrench per the cover manufacturer's specification. Refill oil, run the engine briefly, and check for leaks before returning the Bmw 335Xi to service.

Frequently asked questions

How much does it cost to replace engine oil filter covers on a Bmw 335Xi?
Parts alone start at $40.95 for a Bmw 335Xi engine oil filter cover. Labor is typically one of the lower-cost oil system repairs because access is usually straightforward. Budget roughly 15–30 minutes of shop time unless the housing is deeply recessed or requires intake component removal.
Can I drive my Bmw 335Xi with a leaking oil filter cover?
No. Even a slow oil filter cover leak on a Bmw 335Xi can accelerate into rapid oil loss, especially under highway driving where pressure spikes. Low oil pressure causes accelerated wear on bearings and camshafts within minutes. If you see an active drip or the oil light comes on, stop and address it before driving further.
What causes an engine oil filter cover to crack or fail on a Bmw 335Xi?
The most common causes are overtightening during an oil change, which strips or splits the plastic threads, and heat cycling over time that makes the material brittle. Using an impact wrench instead of a torque wrench is a frequent culprit. Age and UV exposure to underhood heat also degrade plastic covers on older Bmw 335Xi models.
Does replacing the engine oil filter cover on a Bmw 335Xi require draining the oil?
Yes, in most cases. Removing the cover on a Bmw 335Xi exposes the oil filter cartridge cavity, which holds residual oil. Draining the engine oil first — or at minimum having rags and a drain pan ready — prevents a significant spill. Some covers include a built-in drain valve that lets oil drain before removal.
Do I need to replace the O-ring when I replace the oil filter cover on my Bmw 335Xi?
Yes, always. The O-ring is the primary seal between the cover and the housing on a Bmw 335Xi. Reusing the old, compressed O-ring is the leading cause of leaks after a new cover is installed. Many covers sold for the Bmw 335Xi include a replacement O-ring in the package — confirm before you order.
How often should the engine oil filter cover be replaced on a Bmw 335Xi?
The cover itself has no fixed replacement interval on a Bmw 335Xi — it is replaced on condition, not mileage. Inspect it at every oil change for hairline cracks, stripped threads, or a deformed sealing surface. Plastic covers on high-mileage Bmw 335Xi engines are worth proactive replacement if they show any brittleness or thread wear.
