Spark plug! What's with them ?! - Toyota Carina, 1.5L, 1997
For a long time I noticed an unpleasant situation with a spark plug in the second cylinder and after the engine bulkhead the problem did not go away.
The rest of the candles are in perfect order.
Actually in the photo you can see
Mileage: 193,000 km
The engine went over literally 20,000 km ago. Replaced pistons, rings and all oil seals.
The only thing I think can the cylinder itself have a deformation?
Whoa! These are the gaps between the rings and the cylinder walls. I cannot explain this state of the candle otherwise ...
Well, it's probably too early to sin on the rings, but on the valve stem seals, which I want to replace along with the timing belt. If the caps do not help, then there is probably an uneven cylinder mirror = (then I will drive Lukoil and slowly add it.
Does the oil go away? If so, how much?
What driving style?
Do you have blue smoke from the muffler when driving on the highway with a downshift? Well, at a speed of 6-7 thousand when driving, is there smoke from the muffler? (it is better to look from the outside - ask friends and acquaintances)

I am sincerely glad to see you!
Alas, the oil goes away, but very little. Probably about a liter per 6t.km.
The driving style is pensioner. Turns maximum 2500 per minute.
Before the bulkhead, when shifting gears, there was black smoke and white smoke when you pressed the pedal.
Now, unfortunately, I could not observe from the outside, but I will definitely try.
