Unfortunately, the continuation of the epic with an oil leak.
A week after replacing the oil pressure sensor, drops of oil on the floor continued, but to a lesser extent. The problem remained, although its scale decreased. Last Saturday, a visit to the workshop, where there is a lift.
As the respected members Whopper and Oldblue wrote, I had to remove the starter (previously it was problematic since I do not have a car lift).
The painting, which opened after the dismantling of the starter.
It can be seen that another sensor is crying with oily tears. The prospect of a new waste of money saddened me a little, but the mechanic came up with a wise idea - to unscrew the sensor and look at the gasket. We did it.
The gasket is a green rubber ring made of oil-resistant rubber (or silicone? I did not understand until the end). We took it off like a stocking and threw it away. The workshop turned out to be a whole set of the similar green rings of different sizes. We selected approximately suitable diameter and thickness - it stuck like a native. The leak has been fixed.
The rubber ring was given to me as a gift. Payment for work was set at the rate of "how many do not mind." I was not mind for $ 15 - both parties liked this numeral.
I do not know if you are interested in reading all this routine that I am writing. But I made a discovery for myself - this set of several hundred rubber rings of different diameters. I was told that it is not expensive. At different times, I had to buy rubber rings one at a time, and they always cost a lot. It is a pity that I did not know about the existence of such sets before. If I see it once, I will definitely buy it. This is enough for all life and will be inherited by children.
Now I specifically went to Alliexpress in search of a similar set.
Here is a link to the first counter product. https://aliexpress.ru/i/2019931525.html
Oil-resistant / freon-resistant o-rings for less than 10 USD per set. For installation of car air conditioners. A lot of happiness at the price of couple donuts.
geg those o-rings are commonly used for the lines on the AC system (air condition) on a car.
Different color o-rings can tell you where they are used for and the material they are made from. https://www.globaloring.com/oring-colors/
There is another oil smudge found after removing the starter. I hope this does not grow into a big problem and money expenses.
It’s hard to see in the photo, but small drops from under the sealant.
I think when assembling the engine, the joint between the block and the bottom was sealed and a certain amount of sealant naturally protruded. Now this sealant is torn off in one place and I observe the oil under it.
The leak is not large and does not interfere with the normal operation of the engine, but over time it will grow to a full leak. We'll have to disassemble the motor to anew glue this lower part.
And I don’t even know how difficult or easy it is.
I think this lower part - that this thing is what we call it a “crankshaft bed”. In general, some hemorrhoids are waiting for me in the near future.
The sealant between the two surfaces would not be pushed out, because there is no pressure present. The oil you see there can be simply residual from another leak , like the oil pressure sender or the front seal or most commonly, oil spilt from an oil filter change.
The snake oil you posted, could effect rubber seals , but most likely not have any positive effect on the silicone sealants.
