Cleaning intake valves BY HAND?

[ZSHO]

I think a good place to start would be checking the amount of oil inside the CAC with an oil dipstick,mine had less than half an inch of buildup inside,had the dealer suck it out with a compressor type air gun hose,also would check the oil seperator by the rear valve cover by removing it and emptying it out,its held down by two 8mm bolts and a clip closest to the firewall,just remove the pcv valve and check to see how much oil is inside,BTW mine was replaced under warranty and found a large sum of oil inside.  Z

Not to start any debates, but for info....
Ford does not recommend any type of intake valve cleaning and if there is a certain level of valve incompetentence they just replace the whole head if you have warranty.
Also, for what it's worth no fuel additives or solvents are recommened by Ford beyond those already in top tier gasoline. The word from Ford engineers is that all of them accelerate turbo failure due to increased heat and solvents incompletely burned... And that they are working on a fix as this problem is present in all GDI engines and worse with forced induction.... And compounded by the variable valve timing which allows both intake and exhaust valve to be open simultaneously at the end of the exhaust stroke... The idea is to improve scavenging, but you also get exhaust on the intake valves.

I personally believe that the 3.5 GDI in the '17 Ford GT is a step in the direction of a fix by adding a parallel multiport injection system to the GDI and running both... The car has an advertised 600 CHP which is equivalent to about 430-450AWHP, a power level many of us are running.... Point is there is no fueling issue at these power levels so the parallel MPI system must be for something else... Cleaning the intake valves.

Just my $0.02... They need cleaning... Just know the potential and make an informed decision.
There are three You tube vids by Ford Tech Makuloco discussing this. ... Just google the following and they all come up first in the list:

I would think with the 7 speed DCT that the GT is closer to 525 WHP.

I've seen no dynos.... Ford advertises 600 CHP... No tranny involved in the numbers they use.

I did them a few miles ago. Here's a link to where I posted some info about my experience.

Looks like you did an excellent job Marvin! Any sign of problems since you did it in May? Did you add the meth you talked about in the other forum?

[marvinmadman]

No issues yet. Didn't find a good priced used kit and then the oil prices plummeted

I had my car at the dealer a while back for a rough idle and poor mpg that i was experiencing,after connecting the vehicle with the IDS software everything turned out satisfactory but with all the ecoboost warnings against induction services my friendly dealer which i have great relations with was willing to perform an induction cleaning free of charge(go figure)this was a few months back.  Z

Good snag Z! How did your dealer do the cleaning?

To be honest with ya my service advisor recommended it but the senior tech which is a buddy of mine was trying to elude from the idea,have an appt this week will keep you updated on the topic and any findings i can gather up.  Z

wow, I hope my valves are a touch cleaner than that! I just got a copy of a service manual, going to review the procedure and decide if I want to do it myself or pay the dealer.. If I don't have to replace the intake gaskets, and only the coolant needs to be replaced I might as well give it a shot!

[marvinmadman]

Should be exactly the same as the Flex process

Ford policy is to just replace the head if a problem related to intake valve carbon buildup .... Maybe your dealer will mechanically clean... Maybe not.
