M62tu Vanos

The BMW M62tu 4.4l V8 engine was used in several BMW models including the 540i, 740i and X5 V8, as well as the 2002-2006 Range Rover. This engine has a couple of inherent problems that every owner will eventually run into, with the Vanos system being the most common. The main seal and O-ring inside the vanos gear will gradually break down over time until the vanos can no longer hold the required oil pressure inside the gear. This causes poor performance, rough idle when cold, and most of them will rattle like a diesel truck at idle. Rebuilding the vanos units with new seals and O-rings will instantly provide better performance as well as quieting the notorious rattling noise. New vanos units and new chain guides will bring this engine back to life.

  • The M62tu Vanos fits all the following engines.

    • E38 740i
    • E39 540i
    • E53 X5 4.4i, 4.6is
    • '02-'06 Range Rover 4.4l
    • '00-'04 Morgan Aero 8*
  • Vanos Rebuild

    The M62tu units are rebuilt using high performance, specially designed Teflon seals and Viton O-rings and then the outer housing is pressed with special tools under high torque to compress the new seals internally. We always recommend replacing both left and right vanos units together when tackling this job. Replacing only one vanos will just lead to poor performance and excessive rattling.
  • Replace the timing chain and guides

    Another common issue is the plastic timing chain guides. Over time these will become brittle and eventually break apart causing many of the same issues as a worn vanos, including excessive noise and poor performance, not to mention engine damage in worst case scenarios.
    Due to the amount of work involved when replacing either the timing chain guides or the vanos units, we always recommend doing both repairs at the same time whenever possible
  • Installation Notes

    Note that the rebuilt M62tu vanos will typically NOT Ohm out when attempting to check continuity with a volt meter due to the outer housing compression. This does not affect the vanos function in any way. The Ohm test was just to let you know that you have rotated the vanos in the correct direction (counter clock-wise) before tightening the securing bolt.

    Each vanos kit also includes the following replacement O-rings -
    • 4 x engine top cover bolt shaft O-rings
    • 2 x secondary air pipe end O-rings
    • 2 x camshaft chain tensioner O-rings
