Yes sir, you also have to have someone there to oversee production, so they stay within standards. It's all a big game but considering the tariffs this administration has levied, it might just be cheaper to produce it stateside.

Don't get me wrong, I think this is what has been lacking for decades. It wasn't till all this liberal BS, that things changed. We used to tax everyone and they us, as well. It worked fine and countries had no problems and prospered. Now, it's just beginning to come full circle again. It's the price of doing business. Not the price of greedy businessmen, wanting to profiteer as has happened over the past several decades.

What's good for one, is good for all.

Sorry about the soapbox.;)

I think we need to see more details on this fuel rail cleaning port, because I concur about this having 0 effect on the intake port runners and the backs of the intake valves.

Through the fuel rail? How does it clean the back side of the valve then with this being a DI eng? Interesting.

Please correct me if I'm wrong but I don't follow how spraying cleaner into the fuel rail cleans intake valves please see image below.

If you have a clogged fuel inject for a GDI motor then I would agree spraying cleaner into the fuel rail could clean the injector out, combustion chamber, and top of piston. The method you have described would work on port injected vehicles as a fuel-air mixture washes over the intake valves. But on a GDI vehicle like the VN you have to have cleaner in the air stream. This is why CRC and Royal Purple instructions state to spray into throttle body, in order to have cleaner wash over intake valves. I understand that the CRC cleaner doesn't clean the fuel system and that's why I've chosen to run Gumout every 1500 miles. I understand that the CC doesn't completely eliminate oily vapors from reaching the intake valves. The idea is to use cheap products at regular intervals to limit carbon buildup (catch can, fuel system cleaner through gas tank) and use other cheap products like CRC Intake Valve Cleaner/Royal Purple to remove limited carbon buildup at regular intervals like 10k. The cost benefit makes sense especially for folks who regularly take care of their vehicles. A large manual cleaning at like 60k with severe carbon buildup is going to cost you. When I still had my 16' VW GTI with sever carbon buildup it killed injectors and caused tons of missfires. Dealer wanted $1700 do to cleaning and independent shop $700. I'm choosing to spend ~ $10 every 10k miles for CRC cleaner and $10< every 1500 miles for Gumout. My can cost $200 bucks and I can clean personally. Seems like a pretty reasonable investment IMO. Plus you reap the benefits of optimal performance throughout the life of the vehicle instead of declining performance (less power/fuel economy) until you do a major cleaning. Unless the system you described has some wizardry where the cleaner can travel against the direction of airflow and back up over the intake valves I don't see how its possible. But please correct me if I am misunderstanding.

Just so everyone is aware of how the BG GDI Service access the intake system thru Intake Sensor Port.

This procedure is no different than spraying a cleaner through the throttlebody. The question was raised about a cleaner through the fuel rail. This is running a cleaner directly into the intake manifold not the fuel rails.

Let me rephrase, this procedure is similar to spraying a cleaner through the TB. Achieves the same goal with a different entry point. But what does it have to do with the furl rails? I ask because you quoted three comments questioning the valve cleaning through the fuel rail.

Actually, it is different but you'll need to familiar yourself, with the service procedure.

Not really, they all attempt to achieve the same goal. This is properly and completely removing carbon deposits off the intake valves, piston crowns, high pressure fuel pump, fuel lines, fuel rails, back side of the throttle body (unless spraying directly thru the TB) and fuel injectors. Some much better than others. However, unless it's the BG system procedure, with the BG adapter and BG products, they simply don't accomplish the same cleaning.

Again, it's different but you'll need to familiar yourself, with the actual service procedure.:)

I was mistaken at the time and attempting to remember without a direct reference. I subsequently made the correction in my previous post as well. BG does have a system that taps thru the fuel rail but not on the Theta II and this was what I remember at the time.:)

How is anyone supposed to keep, hold a conversation with you when you go back an edit your posts? You do this often on both Forums. You make a statement then you change your position.
Is your day job in politics ??? Its cool though as I still have the emails with the original text. Very confusing.

I'm sorry, there's been no change in my position/s. They're clear.

Sometimes my grammar is not clear and my or typing is inaccurate. I like to be clear for those, who have to translate or don't understand and those who have trouble comprehending English accurately.

If I make a mistake, I'll go back, correct the error and explain the correction as well.

Keeping in mind, this is an international forum. Sometimes, verbiage is misconstrued and a different interpretation is formed, than originally intended.

Getting back to the topic of catch cans.:)

Sure is, if you do the job right when spraying thru the TB, you have to remove the it to clean the backside of butterfly correctly. With the adapter, you don't

Awesome video! Check out the 12th minute. Oil/water separators built in the head covers. Whether you add an external or not is up to you. But the engine most definitely has them.

Thanks for posting this.

Next time I'm under the car I'll have to inspect my chassis sealing. I live in a salty winter environment and what he pointed out at around 30:20 concerns me...

Hey, I checked the history on the replies. @R Veloster N is mostly just adding info into the mix. It's ok to add to/edit comments after they were posted, nothing to get upset about.

So Boomba has released a how-to guide for the Veloster with their catch can. Not sure when it will be available though. Stage 1 catch can video:
