Used Truck Engine Valve Covers & Rocker Covers

Used truck valve covers & rocker covers for European HGV engines

Valve covers (rocker covers or cam covers) seal the top of the cylinder head and protect the valvetrain from dirt and moisture while keeping engine oil inside the head. On modern European HGV engines they also often integrate the breather or oil separator, oil filler neck and various sensors, so choosing the correct cover is important for oil control and crankcase ventilation.

In this category we offer used OEM truck valve covers and rocker covers removed from complete donor vehicles. Typical examples include covers for DAF XF/CF, MAN TGS/TGX, Volvo FH/FM and Mercedes-Benz Actros engines, as well as units for other popular European lorry brands when suitable donor trucks are available.

What you will find in the Valve Covers category

Stock in the Valve Covers category changes as new donor trucks arrive, but it typically includes:

• complete valve / rocker covers for Euro 5 and Euro 6 heavy truck engines;
• covers with integrated breather or oil separator, ready to fit on top of the cylinder head;
• valve covers with oil filler neck and cap, matching the original layout of the engine;
• plastic and aluminium engine top covers used on a wide range of European HGVs;
• selected associated parts supplied together with the cover, such as gaskets, bolts or harness clips, exactly as shown in the photos.

Each listing includes clear photos, OE/OEM part numbers where available and donor vehicle details so you can compare shape, breather layout, oil filler position and fixing points with the cover fitted to your own truck.

Truck brands & typical applications

Most valve covers in this category are taken from mainstream European heavy trucks, including:

• DAF XF and CF tractors and rigids with MX series engines;
• MAN TGS and TGX long-haul, distribution and construction trucks;
• Mercedes-Benz Actros, Antos and Arocs with OM engine families;
• Volvo FH and FM long-distance and regional haulage vehicles;
• other brands such as Scania, Iveco and Renault Trucks when suitable donor vehicles are available.

Because these are genuine OEM components removed from complete trucks, each valve cover is normally matched to a specific engine family, emission standard and rocker gear layout.

Why valve covers and rocker covers matter

A correctly specified valve cover is important for:

• oil sealing – keeping engine oil inside the cylinder head and preventing leaks onto the exhaust and chassis;
• crankcase ventilation – integrated breathers and oil separators help control crankcase pressure and reduce oil mist;
• valvetrain protection – the cover shields the camshaft and rocker gear from dirt, water and physical damage;
• noise reduction & professional appearance – intact covers help reduce valvetrain noise and keep the engine bay looking tidy and original.

Typical reasons to replace a truck valve cover

Common reasons to order parts from the Valve Covers category include:

• cracked or broken cover caused by overtightening, impact or aging plastic;
• persistent oil leaks from the cover body or integrated breather housing;
• damaged mounting points where bolt bosses have stripped or broken away;
• failed breather / oil separator integrated into the cover, causing excessive crankcase pressure or oil carry-over;
• replacing a non-original or modified cover with the correct OEM valve cover specified for your engine code.

How to choose the correct truck valve cover

To minimise fitting issues and ensure the right performance, please check the following details before ordering:

• truck brand, model and engine family – for example DAF XF106 MX-13, MAN TGX Euro 6, Mercedes Actros MP4, Volvo FH4;
• engine code and emission class – Euro 5 vs Euro 6, as the cover design and breather layout may differ;
• breather / separator design – location of the breather outlet and any connections for hoses or sensors;
• oil filler neck and cap position – especially important where cab access is tight;
• mounting pattern and gasket type – number and position of fixing bolts, gasket profile and groove design;
• OEM part numbers stamped or printed on your existing cover, matched against the references shown in the product description.

If you are unsure, you can contact us with your VIN or registration number and clear photos of your existing valve cover and engine top. Our team can help you confirm compatibility before you place an order. For general guidance, see How to Find the Right Part and Compatibility & VIN Policy.

Used OEM valve covers from dismantled trucks

VRA Truckparts specialises in used OEM truck parts sourced from carefully selected donor vehicles. Trucks are inspected and documented before dismantling so that engines, gearboxes and ancillaries can be assessed. During dismantling, our technicians remove valve covers, check the housings, mounting points and breathers for visible damage, and reject units that do not meet our standards.

Usable covers are cleaned externally, labelled with OEM references where available and stored under cover in our warehouse ready for dispatch. To learn more about how we work, please visit Our Dismantling & Quality Process, Warranty & Part Condition, Sustainability & Recycling and Trucks We Dismantle.
