Decarb intake manifold

[joec]

Does anyone know what's the best way of using either Liqui-Moly Petrol Engine Intake Decarb or AC Delco combustion cleaner to clean the carbon off?

I am thinking to spray directly via the intake manifold sensor inlet by removing the sensor or thru the pcv valve inlet to the manifold. This is for Golf MK6 GTI

PCV inlet is a great spot, let it sit for a while too.

How did you manage to get the hose in the inlet? Did you got the engine running at operating temp before doing this?

Thats an aftermarket boost tap, so i removed one of the spare vacuum sources that wasnt being used and it was the perfect size to fit the hose from the Liqui-Moly cleaner. Yes the engine was at operating temperature.

You can also remove the air inlet temp sensor on the front of the inlet manifold and spray in there - but you will need to use something to seal up around the pipe otherwise the engine will want to stall.

Is your after market boast tap connected to a catch can? How did you keep your engine bay so clean?

[Lucas_R]

No catch can - its connected to a Turbosmart blow off valve. Engine bay is clean because i clean it every time i clean the car.

did someone say clean engine bay?





I do mine via the air inlet temp sensor using either nulon foaming intake cleaner or the liquid moly one.

Anyone removed the manifold to see how good a job it's done?

Certainly not - but id like to hope its doing "something". Even if it slows down the buildup (by removing a little bit of buildup each time i use it) ill be happy.
