Thanks, The dog is cool ,it's the neighbor's dog ,but we know each other quite well. Yes it's blowby,and i think it's too much for 200 000 kms. I just changed the oil,and the thermostat isn't working,so maybe the pistons rings will move a bit more freely when it will operate at its normal temperature and with clean oil. I will give some beans to clean up and pressurize all that lol. I will open the engine anyways later on.

👍💪

Merci bien.

Yes,it was quite molested lol My wallet will win haha

406 are good cars,not many left here,contrary to 206. they were the last kind of classic sedan type.

According to an engine oil temperature chart,i'm spot on for the local usual weather. Thin oils used todays are more to reduce engine load than for protecting the engine. Manufacturers tend to reduce engine work for emission purpose,so they can obtain less fuel consumption during testing since the negine has less thick fluid to pump. The wear is mostly during start ups,when you have no oil circulating. so whatever the oil is thin or thick the engine is running without oil for few seconds. I agree that,the thicker it will be,the more time it will take to get it pumped through the engine,particularly in winter. The manual says that you can use from 5w40 to 15w40 weight oil on this car. Next time i will use a 5w40,it's the most common type sold here,but not the cheapest haha. I bought cheap oil not knowing what i was to find out on this engine.

For now,it's holding up with my big ass,but the foam under did suffer too much,it's deformed,and it hurts the back when you seat crooked. I have bought used seats and will make the best mix of foams and upholstery with the 4 seats. Passengers seats are generally way less used,so i have a good combo coming.
