Frequently Asked Questions
How do I know if my rear crankshaft oil seal is failing?
Symptoms include oil leaks near the transmission bell housing, low engine oil levels without visible external leaks, and burning oil smell due to leakage onto hot components.
Can I replace the rear crankshaft seal without removing the transmission?
In most BMW models, the transmission must be detached to access the seal. Some vehicles may allow access by only removing the flywheel.
