Redex revisited.....

Have booked my car in for the Terraclean treatment tomorrow morning....

I don't mind using my car as a guinea pig for OCUK motors :D

(Didn't bother with the £20 Saab offer as they said that it was something they added in the fuel tank which sounds a bit like Redex but more expensive).

Not Redex but I stuck a bottle of BG44k through my Octavia, Punto and MX5... I noticed zero difference afterwards on any of them :p
 
I'm pretty sure my old man runs some Forte cleaning stuff through engines when they are struggling to pass emissions, could be similar to the Terraclean stuff.

Think I tried Redex once many years ago, didn't do anything on whatever small engined car I had at the time.
 
I use redex on my MGB and I've tried seafoam in the past too. I think they do work but old cars(and carbs) get gummed up far more easily than new ones. I wouldn't think it was needed on modern day fuel injected cars.
 
Modern engines shouldnt coke up internally, there should be very little soot inside the cylinders or in the exhaust. if there is then there is a fault making it over fuel.

I think the simplest way to decoke is using water. You need to add water at the throttle, as the water is flashed to steam it removes the soot and cleans everything the same way water-math injection does
 
Ignoring the performance gain, if your injectors are clogged then it will help.

For the sake of £5, it maybe worth doing on an old car, but in all honesty are you really going to see much difference? No.

You are probably right, but adding water to engine will always sound like a bad idea :)

Tell that to the owners of Mitsubishi and VAG GDi/FSi engined cars.

If anyone thinks that Redex/Seafoam/Terrclean will magically remove carbon deposits built up over thousands of miles they are sorely mistaken. Try decoking some old valves and you will soon realise just how difficult the carbon deposits are to remove.

you only quoted part of my sentance.

those engines will clog badly on the intake valves due to the PCV and absense of fuel to wash off the deposits off

That is pretty damn severe, surely something more wrong with an engine!

Newer engines now have the fuel injected directly into the comustion chamber.

Old engines had the fuel injected in the inlet manfold, before the intake valves.

All engines have a pcv system which breaths up blow by which carries oil mist and other junk.

That junk by default ends up on the intake valves. Before the fuel would wash it off but with direct injection it dont.... but some people mistake that for coking up
