Very thorough video. I paid the mechanic $200 to clean them while they were replacing the valve springs.

I recommend installing an oil catch can between the oil separator/PCV outlet and intake manifold inlet. I did this on my 2013 2.0l ecoboost and it significantly reduces carbon build up on the intake valves.

Totally agree. I have a 2018 ST and I installed a Radium PCV plate with baffle and Mishimoto oil catch can. It's one of the best things you can do to mitigate carbon buildup on the valves. It won't stop it completely, but it will definitely help.

Oil catch can are gimmick. If it was good then ford would have included it.

I got a cheap walnut blaster 30 bucks at harbor freight. Worked really good and smoothed my idle. 2013 ford explorer 2.0 eco boost.

EPA sure has flowed up engines with EGR valve. This is a design problem and the new engines have fixed this. Thanks for showing us how to fix the EPA deflective engines. Your method is a good way to do it yourself.

Great video. Well documented

excellent tutorial. THanks

Well explained and detailed guide. Nice one for this 🤝

CRC makes intake valve cleaner, might be a good chemical to use to spray directly onto the valves when you have it open like this vs carb cleaner or brake cleaner. Maybe they all work the same lol I was going to suggest the tube pipe cleaners, but I saw you grabbed some ^_^ but i would definitely suggest he invests in some catch cans..help avoid all that next time. I ran an E30 blend and multiple catch cans for years, last time I looked my build up wasnt nearly that bad...but its been another 30k and I'm at about 90k now. Since I'll be installing the Radium PCV plate, upgraded injectors (and XDi hpfp), I'll be inspecting my intake valves. I'm hoping they're clean from years of ethanol, but who knows! Since its direct injection, it may not've made any difference at all

Use CRC Intake Valve/Turbo Cleaner. If you have an oil catch can, spray it in the exit tube to the intake manifold while the vehicle is running.

Fill interior with gasoline light match run

I have the same engine on my 2016 ford mondeo/fusion (eu version) My idle is also very rough and going crazy and once it's warm it stops. Do i have the same issue as shown in the video?

I have the same engine but there are two wires connected to the back of my manifold on both the left and right sides that prevent me from pulling it out. I can't find any Information on what they are and how to take them off. They have a suction cup and I think a type of push pin that secures it to the back of the manifold.

The electrical connector should just slide off of the clip or you can use a pry tool such as this amzn.to/3VrOOiN to pop the push in clip off the manifold.

You can use the zip tie method to clean valve

Thanks for the tip.

I think if you could soak the valves in marvel mystery oil it would really break down the carbon on them

@@BLUECOLLARGARAGE i will do valve clean and look more in depth if needed . I have done sparks etc … I love my ST … but god it’s a pain in Arse sometimes ..

where does that carbon come from?...if its the pcv,...why not just vent it to atmosphere....i guess it would hurt piston seal...or not?

What about a gun rod with a 45ACP brass brush you can get the rod in a drill and polish that thing without harm the aluminum intake.

I used that exact same method with a Chevy LFX V6 and it worked just fine. I used B12 to soak the valves, sucked it out, and then used the brush and a drill

i would think a 100 hp shot of nitrous plate kit would clean this if used about once per every 6 months....the nitrous would freeze all of the carbon on the valves and make it break off and blow out the exhaust.
