Variant HistoryBMW M3 E90 - Engine History & Specs at a Glance
The E90-generation M3 (2007-2013) was the only M3 ever built with a V8. Sold in the UK across three body styles on shared mechanicals, it's the enthusiast benchmark for naturally-aspirated M cars.

BMW M3 E90
Fuel TypePetrol
Engine Size4.0L V8 (naturally aspirated)
Power Output420hp (414bhp) at 8,300rpm; up to 444bhp on the rare GTSEngine History Timeline
Launched with the S65B40 4.0L V8 derived from the S85 V10, producing 420hp at 8,300rpm.
UK sales begin across Sedan (E90) Coupe (E92) and Convertible (E93); Coupe becomes the best-seller at roughly two-thirds of the 8,262 UK M3s sold.
BMW revises the rod bearing spec (088/089 shells to updated 702/703 tin-aluminium design) in response to premature wear reports.
Competition Package (ZCP) arrives on Sedan and Coupe; the ultra-limited 444bhp M3 GTS lands with only 7 reaching the UK.
Production ends; replaced by the F80 which switches to a twin-turbo inline-six - why this page covers the E90 generation only.

Common Failure
Rod bearing wear is the defining S65B40 issue. The factory bearing clearance was tighter than typically recommended, and bearings are widely reported to show wear well before 70,000 miles - some specialists report failures as early as 50,000 miles. Left unaddressed, worn bearings can spin and take the crankshaft with them, turning a preventative job into a full rebuild.

Reliability on the E90-generation M3 comes down to one component: the S65B40's rod bearings - the issue that dominates replacement demand, and one where catching it early is far cheaper than waiting. Rebuilt S65 units through EnginesMarket use upgraded bearing shells, backed by a minimum 12-month warranty.
Why the S65B40 V8 Needs Attention Before It Fails
Affected Vehicles
BMW M3 E90/E92/E93 (S65B40, 2007-2013)
Typical Failure Mileage
widely reported from 50,000 miles; preventative replacement recommended by 60,000-70,000 miles regardless of symptoms
Root Cause
factory rod bearing clearance was tighter than typical engineering practice recommends, restricting oil film thickness and accelerating wear under the S65's high-rpm operation.

Vehicle Value Check
Vehicle Value Check
A typical UK M3 E90/E92/E93 trades in the region of £13,000-£35,000, averaging around £25,000 `[THIRD-PARTY]`. That puts most cars in the £15,000+ band, where a full replacement is small relative to value - and the £1,200-£2,000 preventative fix is trivial by comparison. Only the highest-mileage, lowest-value cars warrant weighing a full rebuild bill carefully first.
Our Recommendation
Our Recommendation
Approaching 60,000 miles with original bearings- Book the preventative job now - £1,200-£2,000 against an £8,500+ rebuild if it's left too late. Already knocking or finding metal in the oil- Don't drive it further; a rebuilt engine with upgraded bearings is the only durable fix at that point.
Don't Let Rod Bearing Failure Write Off Your BMW M3 E90
This is a rare case where the fix is genuinely cheap insurance - but only if caught in time. EnginesMarket connects you with UK S65 specialists, whether you need a preventative bearing job or a full rebuilt unit with warranty, without the main dealer premium.

BMW M3 E90 Engine ReplacementFrequently Asked Questions
Question 1How much does a BMW M3 E90 engine replacement cost-
A full rebuilt S65B40 supplied and fitted typically runs £8,500-£12,000 through an independent specialist, against £13,000-£17,000 at a main dealer.
- Used engines start from around £3,000 supply-only
- Reconditioned units with bearings addressed run £5,500-£7,500 supply-only
- Fitting adds labour on top of any supply-only price
Question 2What are the signs of rod bearing wear in an S65 engine-
The most commonly reported early warning is a knocking or rattling noise from the bottom end, particularly on cold start-up, though many engines show no symptoms before wear is advanced.
- Cold-start knock or rattle from the engine block
- Metallic particles visible in oil at a service or oil change
- Drop in oil pressure at idle
Question 3Should I replace the rod bearings before they fail-
Yes - this is the one BMW engine issue where UK specialists are broadly aligned: preventative replacement by 60,000-70,000 miles is standard advice, regardless of whether you've noticed symptoms.
- Preventative replacement costs £1,200-£2,000 through a specialist
- A failure that reaches the crankshaft can mean an £8,500+ rebuild instead
- Ask any specialist quote whether it's using upgraded (non-factory) bearing shells
Question 4Is it worth replacing the engine in an E90 M3-
For most E90/E92/E93 M3s, currently worth roughly £13,000-£35,000 in the UK, yes - a rebuilt engine costs well within the car's value, especially against a rare naturally-aspirated V8 that can't simply be swapped for a cheaper substitute.
- Average-condition E90 M3s are commonly valued around £25,000
- A rebuilt engine (£8,500-£12,000) sits comfortably below that
- Only very high-mileage, lower-value examples warrant a closer look before committing
Question 5Does the Coupe, Sedan or Convertible use a different engine-
No - the E90 Sedan, E92 Coupe and E93 Convertible all share the identical S65B40 4.0-litre V8, with no differences in specification, output or known issues between body styles.
- Coupe (E92) accounts for roughly two-thirds of UK sales
- Convertible (E93) carries extra weight from its folding hardtop, with no engine impact
- Competition Package (ZCP, 2011+) is a chassis/aero package only
Question 6How long does a BMW M3 E90 engine replacement take-
A rod bearing replacement is typically a 1-2 day job; a full engine replacement generally takes longer once removal, fitting and running-in are accounted for.
- Preventative bearing job: 1-2 working days
- Full engine supply & fit: allow several days depending on specialist workload
- Always confirm turnaround when comparing quotes
