A common weakness on the 2.5 engine are failing head gaskets. The OE head gaskets can leak on standard and modified cars alike. We address this by removing the engine and cylinder heads. We then service and skim the heads adding RCM head gaskets and ARP studs. The additional clamping force of the ARP stud combined with the seal from the RCM head gasket ensures no further issues for applications up to 450BHP.
