Another case where oil killed the catalytic converter...

Everything that does not burn in the cylinder will burn in the catalytic converter, irreversibly destroying the ceramic insert. Whether it is oil entering the combustion chamber and then into the exhaust, or whether it is unburnt gasoline that burns out in the catalytic converter, the effect will be similar (greetings to the fans of pops and bangs, i.e. the so-called popcorn ;-)). By the way, I don't understand why there are factory oil defects in the 21st century? Technology is moving forward and engines are getting worse. Not only do they drink oil from birth, but their lifespan often ends before they reach 200,000 years of age. km. I guess they should last longer since they are so lubricated (sharp laughter icon). Okay, we know where it comes from... savings, lack of an appropriate number of tests, saving on materials, etc.... but are we sure? Or maybe that's how it's supposed to be? Maybe the car is going to break down after 150,000. kilometers, giving you the opportunity to buy a new one. In this case, the customer first removed the oil defect and only then brought the catalytic converter for regeneration, and that was correct because why pour oil onto a new cartridge. Moreover, even if we used a cartridge with an emission standard of Euro 10 ;-) it would not solve the problem. The composition of exhaust gases will be far from expected. Replacing the cartridge is not everything, you must first remove the cause of the problem. Before cutting the catalytic converter, we noticed a large amount of carbon deposits on the exhaust gas inlet side, directly from the turbocharger, which did not bode well. After cutting the casing, the insert was worn out, but apparently intact, but when we got inside it, we could immediately see the effects of burning the oil inside the catalytic converter. The insert is very melted on most surfaces, such damages significantly limit the flow of exhaust gases, and by the way, we recently did an American car where the insert was so "damaged" that the automatic machine stopped shifting to higher gears because the engine could not reach the desired revolutions. The engine has been repaired, so we put in a new cartridge. They are American and with the VIN number comes ulev2 (ultra low emission v.2), i.e. Euro 5 in our language. We used a 125/140 mm insert to fill the chamber as much as possible after removing the old insert. As always, the whole thing is TIG welded, after assembly and driving a few kilometers, the housing will turn golden and there will be no trace.
