Stone Engine Oil Pan Gasket

About Stone (Ishino Trading Corporation)

Ishino's quality engine gaskets, marketed under the brand name Stone/Ishino, have been highly appreciated worldwide since the company's founding in 1923. That century-long track record places Stone among the most experienced names in the engine sealing business — a heritage that shows in every component the brand produces.

Ishino markets premium-quality replacement parts for a vehicle's fuel, ignition, exhaust, engine cooling, emission control, and other systems under two brands: Stone (gaskets) and TKK (oil seals). Headquartered in Tokyo, the company operates two manufacturing facilities in Japan and one in Singapore. This global footprint allows Stone to maintain tight quality control while serving the worldwide automotive aftermarket.

Stone's gasket catalogue covers all models for Japanese and Korean vehicles, making it a go-to resource for technicians and enthusiasts who work on Toyota, Honda, Nissan, Subaru, Hyundai, Kia, and many other popular nameplates. Stone is widely regarded as an OE supplier, and many industry professionals consider its gasket sets to be reboxed OEM-quality components.

Within the engine, proper sealing is everything. Stone's catalogue addresses the full spectrum of critical sealing points. At the top of the rotating assembly, engine camshaft seals prevent oil from escaping around the camshaft ends — a failure point that can lead to messy leaks and accelerated wear if neglected. Equally important are engine valve stem oil seals, which regulate the thin film of oil that lubricates each valve stem while keeping combustion gases from entering the oil system. Excessive oil consumption and blue exhaust smoke are telltale signs that these small but vital seals need attention.

Lower in the engine, engine crankshaft seals protect both the front and rear of the crankshaft from oil leakage — components that Stone's TKK oil seal division has refined for decades. TKK oil seals are long-established products with world-renowned reputations, supplying hub seals for heavy-duty trucks primarily. For major engine service intervals, Stone's engine cylinder head gaskets deliver the critical combustion chamber seal between the head and block — an application where material quality and dimensional precision are non-negotiable.

Manufactured from upscale materials by means of state-of-the-art technologies and complemented by nearly a century of experience, Stone gaskets and oil seals deliver premium quality and remarkable durability. For anyone maintaining a Japanese or Korean vehicle, Stone represents a dependable, OEM-aligned choice across every major engine sealing category.
