Engine Sealing Kit (OE 04111-30051) for Toyota

Why you need it

When the cylinder head is off, timing service is done, or the motor is rebuilt, every seal must be renewed. This engine gasket kit restores factory sealing, keeping compression tight, oil inside, and coolant in its passages. It helps prevent hard starts, loss of power, and messy leaks. 🛡️

How it works

Gaskets sit between machined surfaces and create a precise barrier. The head gasket locks in combustion while separating oil and coolant. Intake and exhaust gaskets keep air flow correct and stop fumes. Valve cover and stem seals control oil around the valvetrain. With proper torque and clean faces, the engine runs smooth and efficient. 🔧

What if it fails

Oil drips, coolant loss, milky oil, overheating, misfire, white/blue smoke, and low compression may appear. Driving with leaks can warp the head, damage bearings, or clog the catalyst—turning a small fix into a major repair. ⚠️🔥

Install tips

• Clean mating surfaces; no scratches or old sealant.
• Use new head bolts if torque‑to‑yield is specified.
• Follow OEM torque steps and angles; no extra sealant on MLS unless required.
• Bleed cooling system and recheck levels after heat cycle. ✅
