ОМ651 теплообменник! Почему стучит мотор? Или не стучит. W212 пробег 500000км.

#om651 #om651heatexchanger #w212 We disassemble the heat exchanger from my 212th with a mileage of 500,000km. Let's finally talk about the 651 motor heat exchanger, I apologize to subscribers for the long wait, the fact is that we sawed it 1.5 years ago in May 2020. At the very moment when I was doing a big THING on a half-mile run, and the reason for replacing my heat exchanger was a banal leak from a microcrack. Even then, information began to appear that the refrigerator was one of the problems of knocking motors, that they were clogged and the oil was not cooled properly. And in order not to be unfounded, and to be reasoned, I decided to observe the information field on this topic and make a material based on the facts of improper operation of the 651 motor. At the moment when we were engaged in my car, there was a W212 with a knocked-out 651 engine next to the workshop, and I carefully studied the mounted and was shocked by the condition of the heat exchanger. By the way, here is a tip for those who are looking for a Mercedes with a 651 engine – if it is possible to get to the cooling pipe, or the heat exchanger, or the Unified State Register, it is probably easier to do this on the Unified State Register - it stands on top, be sure to disconnect and look at the inner aluminum surface, if it is with scale, then this engine has been overheated for a long time. ✅ My drive https://bit.ly/3nmxpnu To order cars and equipment from Europe: @ Instagram -   / auctioncarstrucks   ✆ Phone +48 516 057 241 (Telegram, Whatsapp, Viber) Music - Kollektiv Turmstrasse - Lapacha (Lake Peoples Slow-Lap Remix)
