Intake valve cleaning

[Mike12086]

For those of you who are running some kind of intake valve cleaner (such as the CRC GDI intake cleaner), are you spraying directly into the throttle body or using a vacuum hose somewhere? Did this on my other DI vehicles in the past and just wondering the easiest way on the Maverick.
Yes I know I can install a catch can ( I haven't), yes I know to use top tier fuel. Just looking for a little extra piece of mind and hopefully no walnut blasting in the future.

I have used CRC intake cleaner with noticeable improvement on my previous DI engines. That giant plume of dirty white smoke exiting the exhaust pipe after the engine soak is satisfying but can alarm the neighbors!

But I would never use it on a Turbocharged engine. That giant plume of dirty white smoke gets sucked into the turbo before exiting the exhaust pipe.

However, as your mechanic is replacing your turbo at 3 times the cost of walnut cleaning - he may notice how relatively clean your intake looks

I you must do it - spray directly into the throttle body. Yes, it is a pain to get down there. Also, CRC recommends for turbo engines that you do early & often to avoid any crud from building up in the first place (and ending up in your turbo).
