Disadvantages of the A20NFT engine
- This engine is more reliable than its predecessor, but still delivers a lot of trouble;
- Many owners are faced with regular oil leaks, and from different places;
- The timing chain has an unpredictable resource and often stretches up to 50 thousand km;
- The weak points of the motor include the electronic throttle and injection pump;
- On specialized forums, several cases of piston destruction are described even at low mileage.
Astra vxr 2015 A20NFT at 60k had slight rattling when starting and driving,traced it to timingchain area when stripped down right hand top chain guide gone broken and fell down into sump, both timingchain full kits fitted, sump removed and debris removed.Engine rebuilt with new oil and filter, runs great but noise when accelerating excessively, But running great otherwise .Apparently common problem on A20NFT engine between 60k & 100k not a cheap fix.
