Direct Injection OTC intake valve kit

[Den69rs96]

Has anyone bought the OTC fuel injector and intake cleaning kit to clean the intake valves on their cars at home? I don't plan on cleaning the injectors, so I could just buy the OTC can and the intake nozzle and save a few bucks. I would probably buy the GM top end cleaner to use. My GMC dealer told me gm recommends an upper engine cleaning every 15,000 miles. He didn't give me a price, but said it would at least a couple hundred. I have two GM DI engines, so bringing our cars in once a year for a cleaning would get be expensive. So far we put 35,000 miles on my wife's acadia since we have owned it and I have 22,000 on my Silverado.

In my experience (automotive technician), the fuel injector service only does a "so-so"
Job, but better than nothing. We have always had to be careful doing this type of service if the vehicle is turbocharged (as in not doing it at all...) because all of the released carbon goes through and can damage the turbocharger.

Carbon build up is a massive issue with direct injection vehicles... it's astonishing to see how much carbon builds up on the back of intake valves after 60k miles. All the PCV system ends up doing is coking up the intake valves, and the injectors are unable to wash the valves off with fuel since they spray directly into the cylinder.

The best way unfortunately is to disassemble and remove the intake...

I don't have turbos, so I hope it would be fine doing it this way. I figured if I did it yearly I could keep a decent amount of junk off the valves. However, if this method is not really effective, I'm not going to waste $$ on the kit. The dealer did not tell me how they performed the service. I'm not sure if the dealer removes the intake or not.

I got the stuff and don't do it. Sure, 15K sounds like a good time for a wallet flush. Drive the thing, heck, they can go 15 on an oil change.

The dealer basically hooks up the identical tool with a cleaning solution (we use a BG product). Like I said it isn't overly effective and as the other poster stated, it's basically another excuse to charge customers for a service.

I have put some fuel pumps in my 91 Ford but the inj system is all original and never had an occasion a squirt of sheet ever solved much of a problem on any other system. I have the tools and even a case of the stuff, was thinking I could sell a couple wallet flushes to get some of it back.. ha.

What he said ^^^^^. Not a complete scam but pretty close to it.

The thing is that after you do this are still left with the original problem if there is one. Money could have been put to good use to fix it.

I would also recommend looking into using a catch can. If you use a catch can, you can eliminate a lot of the carbon from being deposited on the valves in the first place.

Uhm, a 91 Ford doesn't have Direct Injection, that's the deal breaker here. I wonder if something like Seafoam dripped into the air inlet would help?

Thanks guys. Maybe i will consider a catch can instead. I sure don't have this problem with my Camaro lol.
