During our work we always change the following items:

  • Conrod Bearing Shells x12 (Uppers x6, Lowers x6)

  • Castrol Supercar 10w60 M-power Engine Oil

We offer several options depending on the brand of bearings & bolts that the customer would like.

This is because the S54 engine has 2x style Conrods and therefore Conrod Bolts (M10 v M11).
Also, the S54 has 2x styles of Sumps and therefore Sump Sieve Gaskets: Early (Large) v Late (Small).
Lastly, BMW have recently increased their price of the Early (Large) Sieve Gasket and not the Late one.

Regardless of which bearings you choose, we charge £784 labour for the full process.

It includes technical detail and visuals of an area you're never likely to see again on your vehicle. We record up close and personal to show you the inside of your engine and specifically concentrating on the Crankshaft, Conrods, Bearings, as well as see the underside of pistons, gudgeon pins, conrod bolts, and your old conrod bearings. The main highlights of the video are the Plastigauge measuring process to ensure the oil clearance is within the BMW tolerance. As well as an overview and discussion regarding the wear on your old bearings (which you get to take home with you). The video package we offer is not mandatory and is offered at an optional cost of £90 inc VAT.
