Overview
If you own a Range Rover or Discovery with the 4.4L V8 petrol engine, you know that head gasket integrity is non-negotiable. Heat cycling, fuel combustion pressure, and coolant flow stress this critical seal constantly. When a gasket fails—or shows early signs of wear—the repair window closes fast. Overheating, coolant loss, and internal cross-contamination follow quickly.
This premium Multilayer Steel (MLS) gasket set replaces both the right-hand and left-hand cylinder head gaskets with OEM-specification parts that meet or exceed original equipment standards. Built on proven MLS technology—layers of spring steel and elastomer coatings that compress and conform to surface irregularities—these gaskets deliver superior sealing under extreme pressure and temperature cycles.
Whether you're refreshing an aging engine or addressing a known leak, this set delivers the peace of mind that comes from using engine block-critical components engineered for long service life. Each gasket carries a full 1-year warranty and ships with complete fitment confidence.

Installation Notes
Difficulty & Time
Intermediate to Advanced · 4–6 hours per side (experienced DIY) or 8–10 hours (first-time repair) · Requires cylinder head removal and gasket surface preparation.
Installation Steps
-
Drain coolant system and disconnect all coolant, fuel, and electrical connections from the affected cylinder head.
-
Remove exhaust manifold(s) and unbolster any components obstructing head bolts.
-
Unbolt cylinder head using a proper socket and breaker bar in reverse torque sequence (center to edges); discard old head bolts if manufacturer recommends replacement.
-
Clean cylinder head and block surfaces with gasket scraper and solvent; ensure all old gasket material and carbon are removed. Surface finish should be smooth (Ra ≤ 3.2 µm).
-
Install new gasket on the block (not the head); align all cooling, oil, and bolt passages precisely with block ports.
-
Lower cylinder head onto new gasket; thread new head bolts hand-tight in a star pattern.
-
Torque head bolts to OEM specification (typically 60–75 ft-lb in two stages) using a calibrated torque wrench; follow specific sequence provided in your factory service manual.
-
Refill coolant system, bleed air from cooling circuits, and check for leaks before starting engine.
-
Run engine at idle for 5–10 minutes; monitor for steam, coolant seepage, or overheating.
⚠ Critical Safety Note: Head bolt torque sequence and specifications vary by engine year and block configuration. Always consult the official Land Rover service manual for your specific engine before installation. Incorrect torque can result in gasket failure, coolant loss, and catastrophic engine damage. If unfamiliar with head removal, we strongly recommend professional installation by a qualified technician.
