Our customer reported that this 2.5L naturally aspirated Boxster engine was losing coolant, overheating, steaming and loss of power. Our diagnostics showed that it had breached/blown head gaskets. We ended up removing and rebuilding the entire engine. Rebuilt the heads as well. Installed new multi layer steel head gaskets (the Subaru issue is the head gaskets are single ply composite gaskets and that is why they are so weak). We then installed a whole new clutch assembly (flywheel, clutch kit, bearing, fork etc.) as well as hydraulic system. We serviced the timing belt and the water pump as well as replacing the front and rear main/crankshaft seals. The vehicle is back on the road, running as good as new!
