Oil leak from under the engine

Oil pressure sensor, original number: 37240-PT0-014, 37240-PT0-023

So I already wrote above that in winter at low temperatures my Sivka begins to leak oil.

Starting a cold engine at -32 and smudges of engine oil!

Cold start Did the problem go away after changing the oil filter? (It turned out that it did not disappear)

Since this problem was practically not observed in the summer, and I replaced the engine filter at the service station, I could not clearly and accurately determine where the oil was flowing from. But finally I decided to replace it with the same ZIC 0W 0W-30!

Unfortunately, there was little time and there was no camera at hand, so we could not take a photo. Therefore, I will take photos from other Internet resources.

At the oil pressure sensor, the membrane breaks and oil flows out of the engine!

So, now in more detail about the sensor. On the Internet they say that a non-original pressure sensor will not withstand and will also leak for sure. But I read about this problem, quite late, so I bought it anyway, not the original. I will try to put not the original, but how much time will tell the truth!

Today there was a new problem with this pressure sensor. It turns out that it is not so easy to unscrew it. The key is small for 22 and large for 24. A wrench is needed along the way. But on the Internet they write that it can be unscrewed with a 24 head. Next time I will change the oil, I will try with a head. ATTENTION! They say that it is better not to turn this sensor with a key, it can be broken, it is better to turn it by hand, lubricating the thread with a thin layer of sealant.
