Restore Engine Compression: Ultimate Top-End Head Gasket & Bolt Overhaul Kit for Hyundai/Kia 2.4L Theta II (2011-2015)
Are you dealing with rapid coolant loss, white exhaust smoke, engine overheating, or a rough idle caused by low cylinder compression? These are classic, widespread symptoms of a blown head gasket or deteriorated valvetrain seals—a notorious high-mileage milestone for the highly common 2011-2015 Hyundai and Kia 2.4L Theta II 4-cylinder engines. Because these everyday commuter powerplants endure intense thermal cycles and constant load, factory seals inevitably shrink and structural fasteners stretch over time. Restore your engine's factory compression, structural integrity, and leak-free performance with this Ultimate Top-End Overhaul Kit. Engineered strictly for the early-generation 2.4L Theta II platform, this comprehensive package provides every premium component needed for a permanent, professional-grade top-end rebuild.
Performing a top-end tear-down requires considerable labor, making it critical to replace all high-wear seals and bolts at the exact same time. Sourcing individual gaskets and specialized cylinder head fasteners separately is not only a frustrating puzzle but also an incredibly expensive route. This premium master overhaul package maximizes the value of your labor by matching a high-performance Multi-Layer Steel (MLS) head gasket with a complete set of 10 brand-new Torque-to-Yield (TTY) cylinder head bolts. To ensure an absolute, blowout-proof seal, our rigid MLS gaskets are meticulously flat-packed to protect their precision-layered structure during transit, allowing them to easily withstand high combustion pressures and extreme heat.
Key Features & Included Components:
Premium MLS Head Gasket: Engineered from high-grade Multi-Layer Steel (MLS) to prevent future pressure blowouts and withstand the elevated operating temperatures of the Theta II engine.
Complete TTY Head Bolt Set: Features a full set of 10 brand-new Torque-to-Yield (TTY) cylinder head bolts built to strict ES72465-1 structural specifications to ensure uniform, permanent clamping force across the engine deck.
Oil-Burning Solution: Includes a complete set of 16x premium valve stem seals, which are absolutely crucial for fixing the notorious high-mileage oil consumption issues common to this platform.
Full Top-End Reseal Gaskets: Comes complete with a valve cover gasket, heavy-duty intake and exhaust manifold gaskets, a fresh front camshaft seal, and a comprehensive assortment of necessary O-rings and smaller top-end seals for a flawless finish.
(⚠️ CRITICAL FITMENT NOTE: This top-end overhaul kit is engineered STRICTLY for specific 2011-2015 Hyundai and Kia 2.4L Theta II 4-cylinder engines. Please carefully verify your vehicle's exact year, model, and engine displacement before purchasing to ensure proper fitment.)
