Diesel
I have discovered an engine knocking noise and severe diesel blow-by problem in my 2015 Nissan X-Trail 1.6-litre diesel. Do we spend $10,000 for a second-hand engine and have that fitted? The car has done 290,000km and is in pretty good nick as I have owned it from new. The market value for the car according to insurance is $20,000 but looking online it would be hard to get more than $12,000 in private sale if in really good running order. What to do?
