BMW N54 Lifter Replacement

I'm working through hydraulic lifter replacement on a BMW N54. The project follows a ticking-noise concern and takes us into the engine's valvetrain, a much more involved job than swapping an external sensor or gasket. This is a useful look at the work before deciding whether to tackle it yourself.

What you’ll see in this one

A ticking N54 doesn't automatically mean bad lifters. This is the lifter repair on this particular engine, not a diagnosis for every engine noise.

A closer look at this job

This N54 video concerns hydraulic valve lifters and the valvetrain work associated with replacing them. People searching for a 335i cold-start tick or top-end ticking may encounter several possible causes, so establishing where a noise comes from matters before committing to internal engine work. Watch to get oriented to the lifter-replacement project, then consult the correct BMW engine procedure, locking-tool requirements and tightening specifications before attempting a similar repair. No particular ticking cause should be assumed from sound alone.
