Performance Head Gasket Kit for Volvo C30 (2008-2013) 2.5L

High-Performance Multi-Layer Steel Head Gasket and Valve Kit for 2008-2013 Volvo C30 (P1)

What it Does: The Performance Head Gasket Kit restores cylinder combustion sealing, prevents high-boost blow-by, and refreshes the valvetrain on the 2008-2013 Volvo C30 2.5L turbo engine.

The Stock Volvo C30 Combustion Chamber Failure Points

The B5254T7 2.5L inline-5 relies on an open-deck cylinder block architecture that allows microscopic cylinder liner deflection under elevated thermal loads and increased manifold boost pressure. Over time, the factory composite or light-gauge head gasket suffers fire-ring failure between adjacent cylinders. Furthermore, standard torque-to-yield cylinder head bolts stretch permanently beyond their elastic recovery limits, compromising clamping force and causing coolant breach or combustion chamber pressurization. Elevated exhaust gas temperatures (EGTs) simultaneously induce thermal fatigue and micro-cracking across standard exhaust valve faces.

The Engineering Solution

This comprehensive overhaul kit integrates a premium Multi-Layer Steel (MLS) head gasket engineered with embossed active spring steel layers and high-temperature elastomeric coatings to accommodate deck movement without yielding. High-tensile strength head bolts maintain uniform clamping force across the aluminum cylinder head casting to eliminate localized bore distortion. Precision-machined, heat-treated intake and exhaust valves resist stem elongation, guide galling, and seat erosion under sustained high-rpm thermal cycling.

What's Included

• 1 Multi-layered Steel (MLS) Head Gasket Kit
• 12 Cylinder Head Bolts
• 10 Intake Valves
• 10 Exhaust Valves

Frequently Asked Questions & Fitment Warnings

Does this fit the P1 C30?

Yes, this is a direct fit for the 2008-2013 Volvo C30 equipped with the B5254T7 2.5L L5 turbocharged engine. Confirm your specific engine serial number prior to installation, as early production engine serial cutoff variations exist on select 2.5L blocks.

Do I need to follow a specific torque-angle sequence during bolt installation?

Yes, installation requires strict adherence to factory multi-stage torque and angle sequences using fresh engine oil on bolt threads and washer seats to guarantee calibrated pre-load.
