Disadvantages of the VW BAC engine

  • The aluminum block here is without liners, and the coating of the cylinder walls is prone to shedding;
  • The unit-injectors and the tandem pump by 150,000 km already often leak through the seals;
  • Closer to 200,000 km of run, wear of rockers, camshaft cams is common;
  • The intake manifold is also not very reliable, it simply cracks;
  • Also, oil can be mixed with antifreeze due to a leak in the pump and heat exchanger.
