2019 BMW 340i Oil Leak - Valve Cover Gasket or OFHG?

0

Rachel A. · rep 0 · May 22, 4:10 AM · 1 replies · solved · Question

My 2019 BMW 340i (G20) with about 60,000 miles has started showing signs of an oil leak. I'm seeing small drips on my garage floor, and there's a slight burning smell sometimes after driving, especially after the engine warms up.

I've heard the B58 engine can have issues with both the valve cover gasket (VCG) and the oil filter housing gasket (OFHG). I'm trying to figure out which one it might be before I take it to a shop.

Are there any visual cues I can look for to differentiate between the two? Also, what's the typical cost range for these repairs in the US?

Summary: For 2019 BMW 340i Oil Leak - Valve Cover Gasket or OFHG?, work through these steps on your 2016+ vehicle:

  1. Confirm the symptom — note when it happens (cold start, highway, after fuel fill, etc.).
  2. Scan codes — save all pending/stored DTCs; don't clear until you've recorded them.
  3. Check TSBs & recalls — look up your VIN for open campaigns and known fixes.
  4. Inspect the obvious — related fuses, connectors, fluid level, and recent repairs.
  5. Test the common fix — follow model-specific service procedures; one change at a time.
  6. Escalate if needed — burning smell, no brakes, overheating, or stalling in traffic → shop visit.
