Hey bud how much do a cleaning like this cost on 2012 f150 3.5 ? I heard Ford doesn’t do this cleaning is that true ?

[@jasmwhite1]

Do you feel having an oil catch cans off of the PCV valve in conjunction with the CRC cleaner and new PCV valve every 20K would be adequate to keep carbon in check on GDI's? I have a Hyundai with a 2.4L. Thank you.

Too much effort ,, get the big chunks off and then use BG carbon remover or go to a restaurant supply store and get the professional carbon remover for pots/pans (same as BG but a quarter of the price) .. turns that crap to liquid in MINUTES....

Did this on my 14 focus st. Before that it had a few misfires and what not. The carbon build up was pretty bad with 82k. I used crc and let it soak for about an hr on each valve while it was fully submerged. Then scrub with a hard thin brush. Then I would use a small vacuum attachment on my shop vac and suck it up. Repeat until it was smooth. Then installed catch cans 😁. She definitely idles better and has less misfires. Worth the troubles. I'd tape off the other valves that are already clean to keep them from getting debris inside from the dirty ones. great vid and info. Wish I found this sooner.

[@cosmiclawnmower9818]

Thanks for sharing. Just goes to show why GDI coupled with a standard PCV system is a major design flaw in modern engines that are built this way. Any engine that uses GDI should come from the factory with an oil catch can or include redundant port injectors to keep the valves clean.

[@nerd1000ify]

No strict need for a catch can but you do need a good air/oil separator in the PCV system, to get the oil mist out of the blowby and send it back to the sump. A catch can is just another secondary air/oil separator, retrofitted because the OEM one is inadequate (or absent).

I do not know if Ford has a top engine cleaner, personally I use GM product and swear by it. Way better than the CRC crap in my opinion.

Just called two dealers to see what they would charge to clean my valves. Both want to charge me between $135-$300 for doing the same thing I’ve already been doing with CRC’s GDI cleaner; I asked what the service consisted of… they told me they spray/ fog the intake. That’s what I’ve been doing on a regular basis… so, I’ll be doing this process myself. They’ll probably want $2000 to do it.

[@stephenbloom2545]

That’s all due to insufficient filtration on the oil filter. These turbo charged direct engines require a 20 mic filter filtration, anything larger than that you see this happening. Try switching to the Amsoil filter with a good synthetic oil and you don’t have these issues. I use Amsoil signature series oil and I have 441,000 miles on my f150 3.5 ecoboost and I’ve never had these types of issues. I used a 40 mic filter when I first got it and the PCV fluid was black and gritty, I changed over to a 20 mic filter and the PCV fluid turned to a light brown fluid that feels like a good oil. The fluid will burn in the combustion chamber the black gritty stuff doesn’t.

Nice , appreciate the heck out of you and your videos. I have a 96 4 valve cobra with the same design issue . Different design but same issue . I cleaned mine with 1/2” round wire brush. To get around the valve I bent the end of it around itself , And then a slight 20deg bend. I use carb clean to break it up . Then I use brake clean to sterilize it . Blowing with a air gun covered with a rag so it doesn’t go everywhere.

I knew this could be done, everyone says you need to get it walnut blasted. I figured a little bit of time with brake clean and brushes and you could do this in your own driveway. I wonder if applying glyptal to the intake valves would be a viable solution for keeping oil deposits from ever sticking in the first place. I know people who have used that stuff inside crank cases to aid in return oil flow back to the sump, it creates a smooth non-stick surface inside the block.

[@GoodBariusOfTheNorth]

Good idea for a build you'd have to ultra clean each one and somehow bake it before use though, doesn't work to well unless.

Give me the good old days of revving the engine a little and pouring a little water down the carb. Water turns to steam, engine backfired and carbon was gone.😎

Had to do that many years ago on my 74 Vega. Would ping no matter what I did until I used the water trick. Bunch of black smoke came out of the exhaust - no more ping.

@@858415 Thats not true!

[@858415]

@@niceguydmm fuel is sprayed directly into cylinder on gdi engines. Traditional port injection sprays fuel mixture into runner, which cleans back of intake valves. Type of fuel or additive into tank does nothing for GDI cars.

Try an oil catch can it will trap the sludgy oil and all you have to do is drain or empty it every 10,000 miles.

[@miketeeveedub5779]

Someone needs to make an aftermarket kit where you can plumb in a single fuel/solvent injector, like a VW CIS cold start injector. This way you can run a yearly automated service cleaning cycle without any intake manifold disassembly required. I realize that's quite an engineering feat, but I think it would pay for itself after the traditional manual cleaning service, and has the benefit to prevent potential drivability issues too.

[@markm0000]

That would be simple enough. Tap a thread in the intake pipe. Snug a quick connect on there. When it comes time to service install an air line and bring it into the cab then blast it with solvent with the car warmed up at freeway speeds. A couple cans should do the trick.

Here's a question for you. As a dealer tech (not ford) do you think this repair/maintenance should be a warranty based repair or CP? I've had many debates with my warranty admin regarding this and neither the dealer nor the manufacturer has an answer. Just wanted your opinion

[@rays7437]

CP. Carbon deposits are not defects in materials or workmanship. Warranty doesn't cover defects in the engineers' designs. That's why the manufacturers get sued and then offer "customer satisfaction" recalls...

[@dreece2000]

No warranty it’s just maintenance.

I have a 16 escape 1.6l that I have torn apart right now because it has all the symptoms of a bad pcv valve, to find out it doesn't have a pcv valve. It instead has an air oil separator. Have you ever had to replace one? And I figured while I had the intake off I would clean the valves because they were worse than the ones in video

All because direct injection is the best idea ever, since the electric starter.

[@PecanPie1102]

What about the oil separater? That GDI design is problematic.

[@DougHanchard]

The problem isn't the decision to implement Direct Injection. The primary problem is crankcase ventilation that is positive pressure, being fed into the intake manifold. At hot operating temperature, it's not a problem. But during cold start up and warmup, the air in the oil pan, cylinder head and valve train cavity is cold and wet, which is sucked into the intake manifold along with cold EGR air. The oil and unburnt fuel then falls out of suspension and coats anything in the intake manifold and EGR system. Then as the engine warms up to operating temperature, these deposits then bake onto the walls. The problem has been around since the late 1960s when cylinder head / carburetor EGR plates were first used. Combustion engines can only develop negative crankcase pressure using a dry sump oil system. The drawback is complexity, parasitic horsepower loss and oil foaming / aeration depending on design. It also isn't a good application in cold operating temperatures. EGR air pumps did work, but they also were problematic and required allot of horsepower. One of the advantages of propane or natural gas is its cold burn properties. These problems never occurred with these fuels and worked great in older high compression engines used in the 70's and 80s. Especially taxis and city delivery vans. Class 8 trucks with diesel engines do use an oil separator. They can be used in gasoline engines too. But it's plumbing and maintenance headache. You also run the risk of an oil fire if it overflows from lack of servicing.

[@Greasyman.]
