  1. 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.
