Engine damage does not mean the car is scrapped. The following are the specific regulations for car scrapping: 1. Failing annual inspection for 3 consecutive cycles: According to the "Compulsory Scrapping Standards for Motor Vehicles": Motor vehicles that fail to obtain the motor vehicle inspection qualification mark within 3 consecutive motor vehicle inspection cycles after the expiration of the inspection validity period shall be compulsorily scrapped. If a forcibly scrapped vehicle is driven on the road, the driver will face severe penalties including fines and revocation of driving qualifications. 2. Mandatory implementation of National IV emission standards: All National II and National III models that fail to meet emission standards will not be allowed to be registered. For vehicles already registered, those that do not meet the standards will be guided to scrap or compulsorily scrapped.

A broken engine is indeed a headache, but it doesn't mean the car has to be scrapped. I've seen many cars with engine problems before. Some just had a faulty crankshaft position sensor, and replacing it for a few hundred bucks brought them back to life. Others had cylinder scoring but the engine block wasn't deformed, so replacing the piston rings and cylinder liners got them running again. The key is to assess the extent of the engine damage and the overall condition of the vehicle. For example, replacing a used engine in an old Jetta costs just a few thousand yuan, and after repair, it can easily run for another five years. But if you just spent 100,000 yuan on a new car and the engine seizes right after leaving the dealership, you should definitely demand a brand-new replacement from the 4S store. Generally, consider scrapping only if the repair cost exceeds 80% of the car's value. Otherwise, repairing and continuing to drive is still cost-effective.

Among the vehicles I've serviced, quite a few had engine failures, but more were repairable than not. For instance, if the timing belt skipped teeth and damaged the valves, replacing the valve set would cost just over two thousand yuan; if the oil pump seized and caused the crankshaft bearings to burn out, regrinding the bearings could still save the engine. The key is finding a reliable mechanic for inspection, as some unscrupulous shops might give you random quotes once they see the engine disassembled. Nowadays, factory-refurbished engines are quite advanced. For example, replacing a Volkswagen EA888 engine entirely costs only about twenty to thirty thousand yuan, which is much better than losing sixty thousand yuan by scrapping the whole vehicle. However, if the engine block is cracked or the connecting rod punctures the cylinder after water immersion, then scrapping is the recommended course of action.

As an average car owner, my first instinct is to check the warranty period. If still within the three-year warranty, take it directly to the dealership to claim a new engine. Out of warranty, then it's time to do the math: for a car that just had a major service last year, replacing just the turbocharger costs around seven to eight thousand; for a decade-old car with blue smoke from the engine, repairs running into tens of thousands would definitely mean scrapping it. When trading in used cars, note that a car with an unrepaired engine can still fetch a parts price, better than selling it by weight to a scrapyard. Remember my friend's BMW N20 engine burning oil—spent fifteen thousand to fix it and drove it for three more years. The key is not to panic prematurely; in eighty percent of cases, repairs will suffice.
