Now I do have to ask. Is there a risk that I seize the motor up with this water treatment? I'm all for it, but what if the motor stalls while doing this process with water in the combustion chamber. Is there any risk that I should know of going into this??

It's a pretty old and tried method for clearing out of carbon. The chemistry behind it is pretty easy to understand. Just be careful when you do it; you don't want too much water in the motor at once. You don't want to hydro-lock the engine.

Decarbonization is also more of a preventive measure. It won't fix much. If you actually have compression that low(which I am still skeptical about), chances are, it won't do much to improve the compression.

Another way to decarbonize is to just go to an auto-crossing event, provided your car checks out(especially the ignition), where you get to drive hard safely, but not to the point you'd need to do cooling and exhaust mods. You also get to learn about the car's limits and improve your skills. I really want to go to one at some point. Sounds like fun. Maybe someone who's been to one can shed some light.

Hey guys, just so you know I'm not pulling anyone's leg about not showing any symptoms of low compression I took two videos. The first video is the car idling at operating temperatures. The second video is a short clip of me driving it a bit. (Before anyone asks. I shoved my phone in a space between my steering wheel and the gauges, I did not and will not hold my phone filming while I drive) Let me know if anything seems out of the ordinary in your opinion.

you have two lines getting T'd together and 1 line sucking the water through. you can feed the water at a sipping pace where you feed it let it suck air, feed it, suck air, etc.


You are not going to hydrolock an engine this way. you need a lot of water to do that.


The steam will clean the engine internals, and compression may first get worse as you just cleaned off all the oil on the housings. That is why I sip a little 2-cycle oil in at the end to get everything lubed back up. you then need to change the oil, or perhaps not, and run the car hard. you need to get it heated up and cooled, heated up and cooled. If you baby the car it might not get enough heat into the engine to loosen up the seals which are carbon locked or stuck. it might take multiple water treatments and multiple thousands on miles to really loosen it all back up, or might need a rebuild to get everything unstuck if carbon is the main issue. If the engine is damaged, say the housings are bad or what not this is not going to help you, but if you drove the car softly and never really pushed it much, then it could be carboned up. it should help if its carboned up.


When I take my car out on some of the roads I get on it. there are some pretty long 8% inclines at 7-8K feet where I might floor the car in 4th gear the whole 2-3 miles up the mountain where the car can only hit like 90-100mph tops. I also do a lot of other wide open throttle mayhem back there which means I am wide open throttle for perhaps a good 15 minutes to 30 minutes straight (on and off full throttle). water temps at autoX get up to 100-102C max cause of heat soak and I run the car hard at those temps. typically when I am in the mountains the car is in the 78C to 85C range since I have good airflow.
