Waterboxer Cylinder Head Gasket Kit (Pair of Heads)

This JOPEX cylinder head gasket set is a cost-effective alternative to the premium Victor Reinz kit, supplying all seals and gaskets required to install BOTH cylinder heads on 1.9 and 2.1 Waterboxer engines fitted to the VW T3 / Type 25. Ideal for budget-conscious rebuilds, routine head reseals, or keeping an older bus reliably on the road.

What this gasket set does (and why it matters)

Waterboxer engines rely on a precise sealing system between the barrels, cylinder heads, and water jackets. Reusing old seals often leads to coolant seepage, compression loss, or contamination between systems. This JOPEX kit refreshes all critical sealing points for both sides of the engine, restoring correct clamping pressure and reducing the risk of leaks once everything is torqued down.

How it works

The kit provides matched seals for the key interfaces involved in head installation:

• Combustion sealing to maintain compression and prevent blow-by

• Coolant jacket sealing to keep coolant contained around the head and barrel area

• Associated sealing points disturbed during head refitting

While this is a more affordable option than Victor Reinz, the seals are correctly sized and specified for standard Waterboxer installations when fitted to clean, flat surfaces and torqued to factory settings.

What’s included

• Complete gasket and seal set to install BOTH cylinder head

• Suitable for 1.9 and 2.1 WBX engines

• Unlike single-side kits, only one set is required per engine.

When this kit is ideal

• Budget-friendly head reseals

• Daily-driven or lightly used classic T3 / Type 25 buses

• Preventative maintenance where both heads are being removed

• Engines that are otherwise in good condition and not undergoing a full concours rebuild

For high-end restorations or maximum long-term durability, a premium kit may still be preferred—but for many owners, this JOPEX set offers excellent value and dependable results.

Helpful fitting notes

• Always inspect head studs, sealing faces, and the water jacket area before refitting

• Follow correct torque sequence and stages to ensure even seal compression

• A proper cooling system bleed after installation is essential

Parts you may also need (recommended while the heads are off)

• Water jacket sealant (correct type for WBX engines)

• Pushrod tube seals / pushrod tubes

• Exhaust and inlet gaskets if manifolds are removed

• Head nuts and washers if originals show corrosion or stretching

• Fresh coolant and engine oil after refit
