Title: Engine decarbonazation
Post by: Khare on 05 May 2012, 14:58
Was watching wheeler dealers last night and Edd used a machine to clean the inside of the engine. Watch the video in the link.

Interesting I thought, so I searched around and found another way of doing this, using water and nothing more. Apparently it's been around for years.

I also found a product which is called seafoam which supposedly is used in the same way, and it's supposed to work absolute wonders. Shame it's £20 to buy here in the UK, because in the US it's only a couple of quid.

I'm tempted to try the water method, but using a spray bottle to spray a fine mist of water in rather than a jet of water.

This is the result of a water leak (right cylinder) steam cleaning a cylinder over time

Seems a crackpot idea to me  :undecided:

That's what I thought, but the more I research it the more I'm realizing I can't find anything negative (apart from hydrolocking, which with a fine mist is near impossible to do at fast idle). I'm going to give this a try right before I change my plugs. From reading about how it's done it can take anything between 2l or 3l up to 20l of water to finally get clear water coming out of the exhaust. If you think about it, lots of turbo cars have water injection installed, and a few cars from 30+ years ago also had small water bottles under the bonnet that were slowly added to the cylinder to clean it to keep it in tip top condition. Plenty of stories of mechanics doing this to rough running engines prone to carbon build up and running like a dream afterwards.

Water works. I was interested in that machine too on wheeler dealers.

Saw that too. Would be very interested if you go ahead with it to see the results.  :cool:

I seen this wheeler dealer episode too, and thought it was quite fascinating, will also be interested to see how well it works

rember been show that trick meany years ago.

when the old mans s1 v8 landrover  used to have it's pre mot tune up stage 1 used to involve hanging a coke bottel full of water off the open bonnet with a bit of string  and stabbing pin holes in the bottom of it  so water leacked out into the open throated carb beneath.

modern engines dont really need such fuss or bother unless theres something really up.   but cheepo wall paper steamers  can be adjusted to be used for such uses

Yeah I saw that link when I started looking. Looks like an expensive machine though, doubt every single garage will have one.

And although it's a very effective machine, the cost of £70+ is a shame  :sad:

had a bit more of a read up about it and the bullsh!t alarm is almost about to go off.

basicly all it's doing is fueling the engine with something thats not petrol i see a lot of hype about something thats probaly not all that.

on a direct injection engine its not going to clean the crap out the manifolds or ports ( mainly baked oil residue from the block breather )

as you see they pull the fuel return line  my guess be they are useing a diffrent fuel at a higher pressure.

50p says its a mixture of alcohol and solvent   probaly acetone and ethanol or something allong those lines

Water works just fine, just unhook a vacuum line and drop it in a bottle of water. If the engine tries to bog, pull it out quick.

Yeah I think that's what I'm going to do. Going to unhook the vac line that goes to the airbox.

Will try and do it in the next week or so  :smiley:

95% certain there is an ethanol mix going through.
