List of EA888 Parts and Performed Activities During TSI/TFSI Engine Overhaul

How much is TSI / TFSI engine overhaul?

Below is a list of replaced parts and activities carried out during the overhaul of a TSI/TFSI engine with the issue of excessive oil consumption. This list refers to a typical engine overhaul that burns a large amount of oil but has not yet seized or had a timing failure. In the case of a seized engine or one with damaged timing, the repair cost will be higher by the price of the additionally damaged parts. It may happen that during the repair (after disassembling the engine) it turns out that additional parts not listed below need to be replaced. Some part numbers may vary depending on the engine code and year of production, but their prices are the same.

EA888 Parts List

List of EA888 Parts and Performed Activities

EA888 Parts List:

  1. Pistons and Rings - New third-generation pistons are used to replace the old, defective ones prone to causing oil burning.
  2. Cylinder Head Gasket - Replaced to ensure a proper seal after the head has been planed.
  3. Valve Seals - Replaced to prevent oil from leaking into the combustion chamber.
  4. Timing Chain Kit - Includes all necessary components like chains, tensioners, and guides.
  5. Crankshaft Bearings - Replaced to ensure smooth rotation and to support new piston installation.
  6. Oil Pump - Replaced to maintain optimal oil pressure and flow.
  7. Seals and Gaskets - All are replaced to prevent leaks, including main seals and various O-rings.
  8. Cylinder Honing - Performed to renew the surface for the new piston rings to seat correctly.
  9. Bolts and Fasteners - All critical fasteners are replaced with new ones to maintain proper torque specifications.

Performed Activities:

  1. Engine Disassembly - Complete disassembly of the engine to its basic components for thorough inspection.
  2. Cleaning - All parts are cleaned using an ultrasonic cleaner, ensuring they are free of contaminants.
  3. Inspection and Measuring - Every component is inspected and measured for wear and damage. Unsuitable parts are identified for replacement.
  4. Machining Work - Includes cylinder honing and head planing necessary for restoring flat surfaces and proper seal.
  5. Reassembly - Engine is carefully reassembled using all new parts and following manufacturer specifications.
  6. Testing - The rebuilt engine is tested for leaks, compression, and proper operation before being reinstalled in the vehicle.

These activities ensure that the engine not only gets repaired but also restores its performance to meet or exceed original specifications. The cost of the overhaul can vary significantly based on the condition of the engine and any additional parts that may be required during the process. It's important to have a detailed diagnostic to understand the extent of damage and necessary repairs, which can then be accurately quoted.
