Man someone needs to learn how to use a phone camera

So you removed the O2 extenders, Isn’t because the car had catalytic converters codes? Why didn’t the check engine light came on after you put the sensors without the extenders?

I have a 2015 buick lacrosse awd with the same motor i go to super walmart and get it done my car has 148k no problems yet

How many miles does it take to get that dirty? How often should this be done?

How do you tell when the cylinder is TDC? I'm going to remove my intake manifold to replace the injectors, plugs, and coils - can have a look see in the intakes then as well. 60K miles on mine. It was idling a little rough, but a tank with techron and one with Liqui Moly valve clean, and it's nice and smooth now. I suspect dirty injectors.

stand still dude.

It's pretty obvious to me, that this is the first time that this dude has attempted this job. He didn't even know what tools to use!? And yes, you can use the air intake "solution to do this job much easier and MORE effectively! That's how GM teaches their mechanics to get this job done. The older the car, the more times you need to do the operation, because it doesn't all come off at once. Just use your head and do not expect this to be a quick one time fix. I would do it weekly at first and then after a 4 to 5 weeks, go to every other month or so...make sure that you do this AFTER the MAP sensor of the intake...like just before the throttle body opening. and by the way...hasn't anybody ever heard of generic CARBORATER CLEANER? It's much stronger than Sea Foam and is what mechanics have used for over 50 years! Meter the flow of the cleaner spray until just before the engine wants to die AT IDLE; do this MULTIPLE TIMES and you will find your engine running better and MUCH smoother.

Hard to watch this! Camera must've had a vibration issue!! Way too much talking & very poor valve pix.

Gunk is more on the exhaust valve not much on intake

I wish I had my Buick 3.8 Gen I or Gen II back. Unfortunately my Cadillac CTS has the stupid DI 3.6 LFX, and I have burnt-oil smell , ever since oil once seeped beyond the valve cover gasket. The dealer said there was no leak, even though there was an obvious oil stain all along the gasket.

If anyone has ever done this job, you know it is a nightmare. It is better if you have a PROPER walnut blasting setup. Still requires you to knock off last deposits though

I'd love to see GDI engine manufacturers install catch cans stock or some kind of system that would periodically inject cleaner into the intake stream while driving to keep the valves clean. There could be a separate tank, sort of like a DEF system on a diesel.

Is there a way to adjust the timing without marks? I took the chain out and my stupidity allowed me to turn the the sprocket s individually, which turned the cams. Now I have no idea where I am at. Call me an idiot because I am. 2015 Chev malibu 2.5

Huge help....thank you!

Very clever business model, best of luck to you. Wish we had something like this in Phoenix.

I wrecked my 2011 STS 3.6 LLT so I went bought a 2008 CTS LY7 beautiful car with a blown engine...I was just gonna swap out the motor and transmission from the STS to the CTS.Will that work?

wonder if glue on the screw rather small thin not so long l guess screw stuck in tire thread and head flat and between threads rubber glue and screw it back in will work this reaming and plugging tends to be very hard work for beginers even can not do it cos do it wrong so why not try the easy way

why not take the spark plug out set your regulator to like 5psi and just fill the port with cleaner let it sit and dissolve every thing and suck it out..

I have a 3.6, V6 on my 2010 Chevy Traverse.

Good job man

Seafoam... Enough said.

Is all the gunk coming from the pcv valve clogging and gunking up and venting that straight into the intake? If so, what if you just vent the blow by gases straight to the atmosphere, not saying that is legal, but would that be a fix to the gunking on the intake ports?

It's made its name as known as a big piece of shit

i live by 25th st in chicago

When manually turning the engine how do you know when each valve is top dead centre? I want to make sure I know that my valves are closed When doing this.

Guy posted a shitty video on purpose, it's more of ad to his store. No one cleans the GDI valves like this and your video should be called how to take the intake manifold off, that's pretty much all you did moron

Thank God I still have SFI engines in my vehicles!

Why not pour in a cleaning solution like seafoam or similar, let it sit, then suck it out with a vaccuum? You can catch the solution before it enters the shop vac by making a "catch can" with a jar, lid, and a couple hose fittings.

To prevent up to 85% of this, install this system: www.RXCatchcans.com

Good job. Next best to crushed walnut shell media blasting.

I've heard this is a common problem with ANY manufacture that uses Direct Injection (Eg: Ford Ecoboost)

that was one getto cleaning job wtf

3.6 Cadillac cts gdi engine

My car rides fine when driving at idle it has a shake I've replaced the motor mounts and spark plugs its acting up.worse in the cold. Do I need this done. How can I tell and where can I get it done I asked around and no one has a idea what what I am talking about

I personally would not recommend a plug as a permanent fix, plugs are really a temporary measure.

I just got a 2016 impala with the V6. I’m in love with car but the susceptibility of it getting the valves dirty and ruining the engine worries me. Any tips on how to prevent it fro getting too dirty??

Would using CRC often help prevent or keep the gunk from getting to bad in build up??

It doesn't always require to tear the intake manifold off to clean. There are induction cleaning services that can spray cleaners in through the throttle body and cleans the carbon off the valves without dismantling the engine.

I think in the moment 18:15 this will be fuel pressure sensor, am i right?

I think the real question here, is how to install a oil catch can in line with the Pcv to prevent the oil gunk accumulation on intake valves to begin with. This was an overlooked design flaw in these 1st gen direct injection motors that should have come with a catch can installed.

this is a terrible idea. you cant clean the combutstion chambers so you still risk detonation. the brass brush bristles will fly off while spinning and run through the valves. the heads need to come off.

What year Cadillac and which 3.6 engine ? ? I have a 2016 Cadillac ATS Premium AWD with the 3.6L LFX engine ... I wonder if they improved on the carbon build up in that year or not.

Your camera shakes more than a stripper's ASS...

less talk more work

Did or are you ever going to Post the Video how to change the Fuel Injectors?

Where is the video for the fuel injector?

Have you heard about seafoam? 🤦‍♀️

FYI Easy off Oven Cleanerd... wipes away solid hard crust carbon deposits. Became not to let sit. It will eat you aluminum over time.

I would NOT recommend those cheap HF brushes, nor doing this procedure in this manner. Ive used them before and the metal bristles break off all the time. You wanna talk about cylinder scoring- have a few of those fall down in the cylinder. This guy is risking more damage than getting any sort of benefit from doing this procedure. The true cause of this buildup is the pcv valve dumping blow by oil higher up in the intake piping coating the valve stems. A much better and safer procedure is vinyl tubing connected to a shop vac and gently rubbing the edge of the tube against the valve stem. Then soak the closed valves with seafoam and use no mechanical scrubbing!!

Think a catch can may help??
