Engine Overhaul / Replacement Engine 1.8 TSI / TFSI CJSB (EA888 Gen3) Reconditioning

1.8 TSI / TFSI CJSB (EA888 Gen3) — better than factory standard

The 1.8 TSI / TFSI CJSB (EA888 Gen3) is a four-cylinder turbo engine with 132 kW (180 hp), installed in: Audi A3 (8V), Volkswagen Golf VII (5G), Volkswagen Polo (6R/6C), Seat Leon (5F) — model years 2013–2019. The engine is considered robust, but it has design-related weak points in the oil pump and timing chain that can become a costly issue over time. MIK doesn't simply rebuild this engine — we replace the known weak points with revised components.

MIK Upgrades — why this engine lasts longer

The work carried out includes not only the renewal of all wear parts, screws and seals, as well as machining of the sealing and running surfaces, but also the replacement of components that are marked at the factory with weak points and the Limit the motor lifetime.

• upgraded oil pump
  The biggest weak point of this engine is its oil pump, which does not deliver enough oil pressure from the factory and repeatedly causes failures. Without sufficient oil pressure, error messages, rattling noises and loss of power quickly become noticeable and almost always lead to engine damage. For this reason, we use a specially developed oil pump that increases oil pressure in every RPM range and protects the engine from wear.
• Reinforced pistons
  When tuned for more power or driven hard, this engine is increasingly prone to piston damage in the ring area. It is not uncommon for oil consumption to reach 0.5 l/1000 km or more, and compression and performance drop noticeably. The increased temperature in the combustion chamber puts particular strain on the pistons and valves. Modified pistons, improved piston rings and a specially honed cylinder surface provide the solution.
• High-quality bearing shells
  As part of the overhaul, all components are precisely measured and machined. The bearing clearance between the individual components is set to lifetime and performance and thus ensures exceptionally smooth engine operation. In combination with high-quality bearing shells, this engine is then also ideally suited for sporty drivers.
• Reinforced timing chain set
  The increased wear of the timing chain is largely due to the design of the chain and the freedom of movement of the chain links on the guide rails. A revised chain design and a special guide rail geometry ensure maximum lifetime of the timing chains in this engine.
