A fully rebuilt B5254T2 engine for a Volvo XC90 2.5T Gen1 typically costs £1,800-£3,200 supply-only or £2,500-£4,000 fitted. Used units start from £600, and reconditioned options sit between £1,200-£2,200.

• All EnginesMarket quotes include 12-month warranty

The most common signs of PCV system failure include: oil leaks from camshaft seals or crankshaft seals, blue smoke from the exhaust on startup, a whistling noise from the engine, and increased oil consumption.

• The PCV system should be replaced every 60,000 miles as preventative maintenance
• Ignoring PCV issues can starve the turbocharger of oil, causing catastrophic turbo failure
• A simple "glove test" (placing a rubber glove over the oil filler cap opening) can indicate PCV blockage

For a 2002-2008 XC90 2.5T worth £1,500-£4,000, a £2,500-£4,000 engine replacement is borderline unless the vehicle is in exceptional condition with low mileage.

• For vehicles worth over £3,500, replacement is typically viable if the rest of the car is sound
• The five-cylinder engine is known for longevity when properly maintained
• Compare the cost of a rebuilt unit with warranty vs. buying another used XC90

The B5254T2 five-cylinder turbo is generally considered one of Volvo's most durable petrol engines. With proper maintenance (PCV system every 60k miles, timing belt every 80k miles, regular oil changes), many 2.5T XC90s exceed 200,000 miles without major engine failure.

• The engine is shared across S60, V70, S80 and XC70 - proven reliability record
• PCV system neglect is the single biggest cause of premature failure
• Timing belt replacement is non-negotiable - the engine is an interference design

A full engine replacement on a Volvo XC90 2.5T typically takes 3-5 working days for a specialist (5-7 days for a main dealer).

• Timing belt replacement is quicker - 1-2 days
• PCV system replacement is typically a 1-day job
• Supply & fit providers may offer courtesy vehicle options

The 2.5T uses a 2.5-litre inline-five turbocharged engine producing 208hp, while the T6 uses a 2.9-litre straight-six twin-turbo producing 272hp.

• The 2.5T is lighter and simpler - better fuel economy and lower maintenance costs
• The T6 has more power but is more complex and has higher running costs
• The 2.5T's five-cylinder engine is generally considered more reliable than the T6's six-cylinder
• Both are first-generation XC90 engines; the 2.5T was the entry-level petrol model
