smoke comes out of the dipstick

slm friends I just joined you yesterday as of yesterday I bought peugeot 307 1.4 hdi xr car 119 thousand thousand cars no blow paint in the car I showed it to the engine masters they said it was in good condition according to the engine mileage. I searched for some engine blowing or something they said, some are normal, some said that the engine needs to be renewed, I started to be afraid from the first day, I am waiting for the help of friends who have knowledge about the oil filling place. ....

This topic goes through blow-by. My advice to you is to open the oil filler cap on the engine blog while the engine is running and watch the smoke there. A little smoke is normal.

If you turn it on when the engine is hot, smoke will come out.

There was smoke coming out of the oil filling area, but not excessive smoke, not when the engine was hot, I started it in the morning, after 2 km, I looked, I removed the oil pouch, it does not blow, it just comes out like a light cigarette smoke.

look at the exhaust, let's see the bluish smoke, give a little gas to the car

A little smoke is normal. Do you know what kind of oil is put in the car? Keep an eye on the cooling water. Watch it and see, does water decrease?

When the engine is hot, it is normal to get oil vapor out of it ... If you give up to 5000 cycles of gas in the moment, there is no problem if the blue smoke does not come out of the exhaust.

slm friends I showed the car today, the master exhaust fumes are normal, no problem, because the bad fuel is bad, the diesel filter changed oil and fuel, I added additives to the fuel and the engine sound improved but today I was in the city for a little while the temperature was too low 90. I did not clean the bidet fuel tank, because there was dirty fuel left in it. the master said that the diesel filter may go, if the overheating needle escapes in these vehicles, there will be complete danger.

They open fans at 105 or 110

Maybe it is unlikely, but because I have encountered it, I am telling you, whatever your oil level is, it may have an effect even if there is a lack of oil or oil change time.

oil has just changed, I am wondering if the dirty fuel in the tank runs out in time or do I need to clean the tank, will it damage the injectors?
