I've never found so many great yet totaly bizare tips in one place before! I mean, pouring water in your engine?! Anyway I would like to take up the gospel and spread the word, so would it work on a MK2 1.6 driver? Where would be the best place to get the water in, straight into the carb or via one of the many thousand vacuum pipes available?
Vacuum pipe is your best bet - and it will work fine on a driver. It's just an engine, like any other.....
Quality stuff, does it matter which one? Should I be looking for a pipe going to a specific part of the carb? Ideally it would be the one attached to the airbox which goes to the back of the carb since its nicely accessible
On an 8 valve which pipe shall i use, How much water should i let go through? at about 3000revs? Cheers mate Bz
Read the whole thread........ a pint or more if you want, use one of the vacuum nipples on the throttle body.....
Am i Missing out, should I use this method instead of 10k boost, if so any pictures of which pipe to use. I dont want to blow it up. Sounds great anyone tried it on an 8v Mk3 GTi.
Up to you whether you use it or not, I'm only talking from personal experience and it's also a very well known, albeit old, method of decoking an engine. Which is exactly what 10k boost does. Use a pipe coming off the throttle body, as mentioned before. One long enough to reach your water container.
I gave this a go today as my engine was running on (2 litre, Weber carb). I used the vacuum pipe which goes into the line connected to the brake servo (there aren't as many to choose from as on a 2E2). This line goes into the left hand side of the inlet manifold) It sucked in 500 ml of water in about 20 seconds, loads of steam came out the exhaust, now it doesn't seem to run on. Does it matter that it went into one side of the inlet manifold, will the water have gone into one cylinder, or will it have sucked it into all four cylinders? I may do it again at the weekend when I have more time (take it to the local KFC car park so I didn't upset my neighbours!!!). Steve
Well if it's stopped it running on, it's got rid of the coke/carbon that was causing the running on.... as long as the revs were up at a decent level you should have got water to all 4 ok.......
I tried this recently and it didn't do that much much as far as I could see, but I think thats because I dumped most of a tin of carb cleaner through the engine a while back. You should have seen the black sooty stain left on the carpark after I had finished
i've just tried this, only dared like half a pint, might do abit more engine struggles like f**k with water in, so i kept dipping it in and out.
Keep the revs up to 2 or 3k when it bogs down, using your hand on the throttle body - it won't suck up too much too quickly if you are only using a wee vacuum hose. Think of the capacity of your combustion chambers, combined, then think how much water it would take to hydrolock the engine..... at 3k revs a minute....
Peeps that have done the water way of cleaning the engine, have u waited for the car to get hot or just from cold.
Meant to be done when the engine is warm as I'd imagine it'd be more risky as to whether or not the water would flash to steam immediately. Gonna give this a try on my valver when the next oil change is due.
Revived LoL I was just reading thought this and talked to one of our older engineers in work, and he said he had never heard of this but it's a good idea, it should work wonders, he also said that if to much water got it it could seize the engine?? not sure if he's right or not? He also mentioned another way was to take out the plugs and put a teaspoon of the original redex (upper cylinder something or other) down each hole, leave over night to soak and then turn her over! and that should clear the crap!
