Modern engines are technological wonders, but even the most sophisticated engines can encounter problems. In workshops across Europe, we are increasingly encountering two engines with frequent head gasket problems: the Mazda 2.2 SkyActiv-D (SH-VPTR / SH-VPTS) and the Renault 1.2 TCe (H5F 400).

Although the symptoms vary, the underlying causes are often related to contamination and thermal overload. That is why Wilmink Engine Parts has developed private label head gaskets that are specially tailored to the high loads of these engines: WG2328912 for Mazda and WG2328913 for Renault.

Mazda 2.2 SkyActiv-D (SH-VPTR / SH-VPTS)

Common problems and causes

Various design challenges make the Mazda SkyActiv-D particularly vulnerable:

• VVT camshaft wear
  Early models (2013-2016) suffered from accelerated camshaft wear, resulting in contamination of the engine with metal particles.
• Leaking injector fuel seals
  When exposed to extreme heat, these sealing rings deform, allowing combustion gases to enter the crankcase. This causes rapid oil contamination, preventing the engine from receiving proper lubrication.
• Contamination of the turbo
  Whether it's metal particles or sludge buildup, the turbo has to contend with reduced oil flow, leading to overheating, power loss, and ultimately turbo failure.
• Damage to the vacuum pump
  Contaminated oil attacks the vacuum pump, which can cause the brake booster to fail and internal damage to occur.
  
• DPF blockage
  Frequent short trips prevent proper regeneration of the DPF. The increased back pressure puts strain on the engine and cooling system.
  
• Deterioration of the cooling system
  Old thermostats or clogged radiators reduce coolant flow, leading to local overheating and increased pressure on the head gasket.
  
• Oil contamination and consumption
  Combined problems quickly deteriorate oil quality, leading to poor lubrication and ultimately engine damage.

Consequences for the head gasket

All these problems converge at the head gasket:

• Overheating and poor sealing

• Mixing of oil and coolant

• Loss of compression

• Total engine failure if not repaired

The solution: WG2328912

WG2328912 is Wilmink's answer to this challenge. This private label head gasket has been specially designed for the Mazda SkyActiv-D and manufactured according to OE specifications.

Whether you are performing a complete overhaul or replacing gaskets as a preventive measure, this part offers the sealing reliability you expect from a head gasket.

Renault 1.2 TCe (H5F 400)

Common problems and causes

The Renault H5F 400 engine is also no stranger to head gasket problems:

• Excessive oil consumption
  Poor sealing of the piston rings allows oil to enter the combustion chamber, which can lead to poor combustion and increased oil consumption.
• Carbonized pistons and poorly sealing piston rings and valves
  The current use of thin piston rings, particularly oil scraper rings, means that there is a risk of these quickly becoming contaminated and clogged, resulting in increased oil consumption. Burnt oil leaves carbon deposits, including on the valves, which increases the risk of defects.
• Cylinder wall wear
  As a result of the overall internal contamination of the engine, lubrication is reduced, causing damage to the cylinder walls, which in turn leads to even higher oil consumption and engine contamination. Friction and oil aging also lead to a loss of oil pressure and overheating of the internal engine parts.

Consequences for the head gasket

The consequences of the previously mentioned problems are:

• High combustion temperatures
• Engine knocking
• Overloading of the material, which can lead to coolant loss and engine failure

The solution: WG2328913

WG2328913 has been developed for the specific challenges of Renault 1.2 TCe engines:

• Built for high thermal resistance
• Provides reliable sealing, even at high combustion pressures
• Extends engine life.
