• Holden rocker cover
• OEM style with 2 baffled breather holes and twist-in oil cap provision
• Precision manufactured in steel and then triple chrome plated
• Suits Holden 161, 179, 186, 202 engines
• Not suitable for roller rocker setups

• Engine Application: Built for the Holden Red, Blue and Black inline 6 cylinder family, which share the same head family across 149, 161, 173, 179, 186 and 202 cubic inch displacements. Suits EH, HD, HR, HK, HT, HG, HQ, HJ, HX, HZ, WB, LC/LJ Torana, LH/LX/UC Torana and VB through VL Commodore restoration builds where a factory-correct cover look is wanted rather than a tall aftermarket or finned design..

• Not Suitable For Roller Rocker Setups: This cover is OEM profile only and will not clear roller rocker arms, shaft mount rockers or a high-lift camshaft. If you are running aftermarket performance valvetrain, you need a tall rocker cover instead. Standard pushrod valvetrain only..

• OEM Style vs Aftermarket Logo Covers: This is a faithful replica of the factory Holden 6 rocker cover shape and finish, including 2 baffled breather holes and a twist-in oil cap provision built into the cover. Compared to the aftermarket 202 logo or no-logo variants, the OEM style is the closest match for period-correct restorations where the engine bay needs to look factory.

• 2 Baffled Breather Holes Built In: The cover has 2 built-in baffled breather holes, which means the internal baffling that controls oil splash off the rocker arms is integrated into the cover rather than relying on separate baffle plates. The baffles stop oil being pulled out through the breather ports, reducing oil consumption and engine bay oil mess.

• Twist-In Oil Cap Provision: The cover includes a twist-in oil cap location, matching the factory Holden 6 setup. The oil cap is not included in this listing and needs to be sourced separately. A chrome twist-in oil cap finishes the look if a fully chrome dress-up is the goal.

• Triple Chrome Plated Construction: Pressed steel base with triple chrome plating gives a deeper, more reflective finish than single-layer chrome and improves long-term durability against oxidation and chip-through. The OEM-shape pressing keeps the look factory-correct, which is important for restoration builds where modern aftermarket-looking covers would feel out of place.

• Gaskets and Grommets Separate: Gaskets, grommets and breathers are not included and need to be sourced separately. The matching chrome finned side plate pair completes the top-and-sides dress-up.

• Practical Buyer Tip: Before fitting, confirm your valvetrain is standard pushrod with no aftermarket roller rockers or shaft mount rockers, as the OEM profile will foul anything taller than factory. Clean the head face thoroughly before fitting a fresh gasket, torque the bolts evenly to spec, and keep the chrome bright with a soft microfibre wipe-down rather than abrasive polishes that can dull the plating over time.

Note: grommets and breathers not included.
