What BMW M-Car Rod Bearing Repair Involves
Rod bearing replacement on a BMW S54 straight-six or S85 V10 is a precision bottom-end procedure. We carry out the work in our Billericay workshop using BMW factory torque specifications and plastigauge clearance measurement.
The process involves preparing the engine, removing the oil pan to access the connecting rod caps, taking out the old bearings, inspecting the crankshaft journals, and installing new rod bearings with measured clearance. The oil pickup and sump are cleaned, and the engine is reassembled with fresh oil and a new filter.
For thorough bearing replacement on these M-car engines, we often remove the engine from the vehicle to access the crankshaft properly — ensuring every tolerance is met.

Frequently Asked Questions
What is rod bearing replacement on an S54 or S85 engine?+
Rod bearing replacement involves removing the oil pan, taking out the connecting rod caps, removing the old bearings, inspecting the crankshaft journals, and installing new bearings with precise clearance measured using plastigauge. The engine is then reassembled to BMW factory torque specifications.
Why might an S54 or S85 engine need rod bearing work?+
Our service focuses on the repair itself — the work involves replacing bearings that have reached the end of their service life. We do not offer diagnostic advice on why bearings may have worn; our role is the precision bottom-end repair.
Do you remove the engine for rod bearing replacement?+
Yes, on both S54 and S85 engines we typically remove the engine from the vehicle to access the crankshaft properly and ensure every clearance and torque specification is met accurately.
What's included in the rod bearing repair price?+
Our price includes new rod bearings, bolts, gaskets, seals, oil and filter, plus full clearance measurement, reassembly, and testing. The work is carried out in our Billericay workshop and backed by our 12-month unlimited-mileage warranty.
How long does S54 or S85 rod bearing repair take?+
We aim to complete the work within our standard rebuild turnaround. The exact time depends on the engine and whether the vehicle is already at our workshop. Contact us for a current estimate.
Can you recover my BMW if it's not driveable?+
Yes — we offer nationwide engine recovery from £70. We can collect your BMW from anywhere in the UK and bring it to our Essex workshop for rod bearing repair.
