BMW M60 / M62 / M62TU Family

All Engines

  • Oil pump bolts can sometimes back out and fall into the sump
  • Oil separator valve can foul up – symptoms include poor running, excessive oil consumption, and a whistling noise; requires replacement or removal and cleaning of all tubes leading to and from it
  • Although the timing chain tensioner usually doesn’t fail, it can wear out, causing the chain to make a lot of noise from flopping around – on M62 and M62TU engines, this can accelerate wear on the timing chain guides (see below)
  • Valve cover gasket can leak oil into the spark plug wells
  • Rear main seals can leak oil

M60

Problems

  • Cylinder liners could fail due to fuels with high sulphur content – this was only a problem in the 90s, as fuel today has much less sulphur in it. Generally speaking, any car that is running today should be fine. BMW also replaced many engines under an extended warranty with some that have a stronger cylinder lining.

Problems

Inherits all of the M62’s issues, plus…

  • VANOS failure – causes lack of power and rough idle that “sounds like a diesel,” requires rebuild for around $1k
  • May throw CEL because of problems in the secondary air system caused by carbon buildup in the cylinder heads – cylinder heads must be removed and cleaned
