You could use a hose hooked to the vacuum line to the intake to input the MCCC

Orian.. Keep in mind you are posting in RX300 forum and the picture you shared is of a different engine than that of a RX. You will get more accurate advice if you post in IS forum.

IMHO ... if you dont have a problem... like preignition or engine run-on after turning the ignition key off .. then stay away from doing un-natural things. Lot of bad things can happen when a well intentioned 'improvement' is tried. I grew up with a diesel car, and those are high compression engines ... where introduction of water in the chamber leads to a disaster.

Agree totally with salimshah, you have to be very careful with water injection, you run the risk of hydrolock if not done properly which could cost you a lot of damage.

Let the engine have enough water to just make it partially stutter and then back off. You DO NOT WANT to hydrolock the engine. Personally I would only do this to clean the catalytic converter. I would use sea foam in the gas to clean the valves. Do the water at your own risk....
how do you use the seafoam on gas?

Do you have a problem that you are trying to solve or just itching to do something.

Instructions are on the seafoam bottle.

Mostly folks pull of the vacuum hose to the brake booster.

Personally I am not in favor of any additive/cleaner. Maybe a high quality cleaner in the gas at the most.
