Common Problems
Aston Martin DB2 Engine Problems - What It Costs to Fix & When Replacement Makes Sense
The Aston Martin DB2's LB6 and VB6 engine families are robust but age-related failures are common. Wet cylinder liner seal failure, oil leaks, and timing chain wear dominate replacement enquiries. Every rebuilt engine supplied through EngineMarket includes upgraded internal components designed to address original failure points - plus a minimum 12-month...
Wet Cylinder Liner Seal Failure - Why Aston Martin DB2 Engines Suffer Coolant Ingress
Wet Cylinder Liner Seal Failure
Most affected vehicles
Aston Martin DB2 Sports SaloonDrophead Coupe
Aston Martin DB2 Sports Saloon, Drophead Coupe, Vantage (1950-1953, LB6/49 & LB6B/50); DB2/4 variants (1953-1959, VB6E & VB6J)
Failure mileage range
50,000-80,000 miles since last rebuild
Typical failure window
Root cause
Original cork/rubber liner seals degrade with age and heat cycles, allowing coolant to bypass into the sump and contaminate oil.
Repair options & estimated costs (UK ranges)
| Repair tier | Dealer price | Specialist price | What it involves | Longevity / suitability |
|---|---|---|---|---|
| Minor - Seal Replacement (Engine In Situ) - Not recommended for DB2 | £3,500 - £5,500 | £2,200 - £3,800 | Attempt liner seal replacement without full strip; high risk of incomplete repair | Short-term fix only; seals often fail again within 12 months |
| Intermediate - Partial Strip & Seal Renewal - Viable if block sound | £6,500 - £9,500 | £4,200 - £6,800 | Remove cylinder head, replace liner seals, machine head if warped, reassemble | 20,000-40,000 miles if block and liners are undamaged |
| Full Replacement - Rebuilt / Reconditioned Engine - Recommended for certainty | £12,000 - £22,000 | £8,000 - £18,000 | Supply of fully rebuilt LB6/VB6 engine with upgraded seals, bench-tested, ready to fit | 40,000+ miles with proper maintenance; includes 12-month warranty |
Our recommendation
On a DB2 worth £80,000-£250,000, we recommend the full rebuilt engine option. Partial repairs risk hidden damage to bearings and crankshaft from coolant-contaminated oil. A specialist rebuild with upgraded seals delivers long-term reliability and preserves concours value.
