Most affected vehicles
Mercedes Benz SLS AMG Coupe (M159.970)Roadster (M159.971) (2010-2014)
Mercedes Benz SLS AMG Coupe (M159.970), Roadster (M159.971) (2010-2014)
Failure mileage range
45,000 - 75,000 miles
Typical failure window
Root cause
The original piston ring tension loses elasticity under sustained high-temperature operation, allowing oil to bypass into the combustion chambers and increasing crankcase pressure.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - PCV & Seal Refresh | £1,800 - £2,600 | £1,200 - £1,800 | Replaces crankcase ventilation valves, external gaskets, and valve stem seals to manage pressure without engine removal. | Temporary mitigation only. Viable if oil consumption is under 1 litre per 1,000 miles and rings are intact. |
| Major - Piston Ring Replacement | £12,500 - £16,000 | £8,500 - £11,500 | Engine strip-down, honing cylinders, fitting revised A1590300001 piston rings, and reassembling with fresh bearings. | Cost-prohibitive on a V8 requiring full disassembly. Only recommended if the short block is otherwise pristine. |
| Full Replacement - Rebuilt / Reconditioned Engine | £22,000 - £28,000 | £14,500 - £21,000 | Supply & fit of a dyno-certified rebuilt M159 engine featuring upgraded piston rings, refreshed valvetrain, and full ECU recalibration. | Best long-term value. Restores factory performance with collector-grade warranty and documented provenance. |
Our recommendation
On an ultra-premium SLS AMG, stripping the M159 for a ring replacement is rarely economical due to the intensive labour and ancillary parts required. We recommend proceeding directly to a rebuilt engine if consumption exceeds 1 litre per 1,000 miles or blue smoke is present on cold starts. The rebuilt unit includes revised rings as standard, eliminating recurrence risk.
