Decarbonizing with water ... - Toyota Vista, 2.0 liter, 1993

   Toyota Vista 20 1993

I read here recently a topic on the Drome about decoking with water …
Greetings to all, dear! As a result, zadolbal oil consumption — a liter per 1000 km. Changed the caps — the result — a little better. In the mornings, it smoked in the cold so that it was a shame to stand next to the car. Everything is in smoke. just tin. I read on the internet about decarbonizing with water - there are a million opinions ... In the end, I decided.
For this, 5 liters of water, 10 peroxide tablets, and a dropper system were purchased.
The main thing is not *****.
1. We start the car.
2. Open the hood.
3. We set the speed to 2 thousand
4. Remove the vacuum pipe from the intake manifold
5. Connect the dropper system.
6. We are freaking out from the amount of smoke, steam, shit flying out of the exhaust pipe.
7. Do not worry about the catalyst — I cut it out a long time ago.
8. The water runs out, the machine is running, we connect another bottle with 2 liters of antifreeze.
9. We are freaking out from even more smoke.
10. Bottom line: started in the morning — smokes, so I think ugliness … drove 10 km … the smoke disappeared altogether! no hint of blue. when you sharply give gas, the smoke is visible blackish about 5-5.5 thousand. To date, mileage after decoking 1330 km. oil went 1 mm on the dipstick. Happy as an elephant.
I post pictures of the process.
// and it caught fire to try ...

This action was done on Sunday at the dacha, they ate 3 liters of water.
Noticed:
1. decrease in detonation
2. the machine began to accelerate more vigorously (at the start it constantly slipped)) an old habit of tearing from a traffic light, but before I did the slip myself, if I wanted, now by itself),
PS I won’t say anything about oil consumption, but after 2 days of constant driving, the detonation returns and the machine starts to dull again ((
when checking the candles, small chips of soot were noticed.
Conclusion:
1. I’ll try to shed more water.
2. If the soot flies off in chips, then it still helps, well, at least a little)).
3. I’ll try again, if again for 2 days, then I won’t do it again, because with our frosts, the engine will definitely stop, because. a lot of water remains in the engine, and so that it does not freeze, you have to oil the engine for a long time after the procedure

PSS
Photos from the first time, in the second, i.e. there was no camera on Sunday, but the show was notable! smoke ppt...

no, after this decarbonization, about a month later, a major overhaul of the engine was made (he took out oil). so, according to the master, there was not much carbon deposits on the pistons, oddly enough, ... I can’t say, but something contributed to this ... at least nothing bad happened!

Are you afraid of such experiments?

In winter, I don’t advise, but for warmth, you can search on the net, in youtobe ... it was detailed on the Drome ...
just look in the search. there's a lot of info out there. and antifreeze and something else. I did it only with water, at least it will at least evaporate for sure
