Engine blowing

Friends, I have a Peugeot 301 with 135,000 miles on it. When I pull the oil dipstick and open the oil cap, there is a blowing sound. I took it to 2 mechanics in the industry, and both of them pressed the gas at 3,000 rpm and said the engine of the car is fine. A recent mechanic pulled the oil dipstick and says there is a blowing sound in this car. Who are we supposed to believe? Can anyone who owns a 301 help me? It's a 1.6 diesel car... There is no smoke from the exhaust, there is nothing wrong with it while driving. I changed the oil 2,000 km ago and drove around, it's been 2,000 km and I checked the oil and fluid, there is no gram loss. Can friends who have the same car provide some information?

I mean, all these cars have this problem since the day I bought it. This is not a problem especially in diesels. It blows steam from the upper camshaft. When it is very hot, a little steam comes out of the oil dipstick. For example, when I open the upper oil cap of my car, it gives out steam but when I leave the cap on without turning it over, it draws it like a vacuum. It does not throw it. In a car with a compression leak, the cap does not stay in place, it bounces. I know this because I have experienced the same problem in my VW group car. My gasoline Seat Toledo 1.4 TSI room 2017 has 80 thousand km and it also has steam from the cap. What do you mean, all these cars have a dead engine? Don't believe everything you hear. Do your maintenance properly and continue. Nothing will happen. Those engines are not bad engines. Have a nice drive. As I wrote on the other side, your car is perfectly normal, do your maintenance, start the engine...

What does engine blow-by actually mean? The logic is roughly the same in diesel and gasoline engines. The timing varies from vehicle to vehicle as the piston ascends within the liner. This timing, combined with air and fuel, creates an explosion in diesel engines, while in gasoline engines, it's ignited by the spark plug. The resulting explosion generates burning gases, high temperatures, and high pressure. This pressure forces the rising piston downward. This chamber is called the combustion chamber. The pressure generated in the combustion chamber is maintained above by the valves, the cylinder head, and the cylinder head gasket, ensuring leak-proof performance. Below, on the piston side, are the piston rings. Due to the damage to the piston rings, the piston rings can't hold this pressure, and the resulting combustion gases and pressure are forced into the oil pan, the lowest part of the engine. This pressure and gases are removed from the engine through PCV (crankcase ventilation) and returned to the combustion chamber through the intake. If a turbocharger is equipped, the resulting soot sticks to the turbocharger, intercooler, intake manifold, valves, cylinder head ports, EGR, throttle body, and other components. The soot buildup prevents the engine from breathing properly. Advanced levels shorten all these parts and engine life. In advanced stages, oil leaks can occur due to pressure leaks. As the pressure escapes from the piston rings, it is expelled through a hole opened in the engine. This hole refers to the oil dipstick, oil cap, etc. This is called blow-by. Whether your vehicle is diesel or gasoline, you should have a compression test done to clearly see the extent of the leak. In this case, there's no guesswork involved. The solution is very simple.
