I have not been able to find any topic pertaining to this on the site but please excuse me if this is a duplicate posting.

I remember years ago there was a system that slowly injected water into the engine using engine vacuum to slowly bubble water and pull vapor into the engine. This got me to thinking about a system that might allow for the very slow bleed of a solution of intake valve cleaner to do the same thing on GDI engines to prevent crud build up on the intake valves. Has anyone ever tried this? My thinking was something like a PEA cleaner diluted with a solvent like MMO
(or any other compatible combustible solvent of your choice) slowly pulled through the system. Perhaps a usage rate of 100 mls per 500 miles or so (all depends on the strenght of the solution). An easy to refill bottle would be the ideal container for such a solution with the injection mechanism as part of the lid.

Thoughts, please!

I like the idea, but i see a problem with dry flow intakes. If it pools anywhere, and you step on the gas, you could slug (hydolock) the cylinder. Also you would have to have some way for it not to vaporize( either into the intake or the atmosphere) when the engine is parked but hot.

I think it would have to be more of an attachment that you use on say a 20 mile drive before an oci, not a continuous system.

It was called a “Top-end Oiler”........made as a dispenser for MMO.
I think they are still made.

Still sounds like a plausible solution provided its only used when driving at speed, and with a warm engine.

Pretty cool thread...often wondered if there were aftermarket alternatives available to help with carbon buildup...looks like there's a few.

Anyone ever actually use one? How did it work out? And what is the solution being used? Water? A mixture of water and something else?

BMW uses a water injection system on the M4 GTS.

Or install a meth injection system, there are many aftermarket systems available.

My thought... just one more thing to break/go wrong. Get a can of Regane IVC spray or this..👇. It's got a mix of solvents w/PEA.

Isn’t there a general caution about using products like this with turbocharged engines like the OP’s? I thought the concern was carbon bits breaking off and potentially damaging the turbocharger exhaust gases are powering.
