Some would recommend a CATCH CAN to catch air-born oil being recirculated back in over the input valves.
I fitted one when we first go the car. It collects a LITTLE amount of oil but probably not enough to make any difference to contribute to contaminating the back of the valves with carbon etc


For what it will cost you to get a "TECH" to look at your engine, you can buy your own Borescope camera (ie at Harbor Freight), and do your own as many times and as often as you want, while maintaining Photographic records. Most Borecope Cameras (ie harbor Freight) take SD cards, where you can record both Pictures and Video.

You can also get cheaper USB Borescope cameras for your Smartphone.

Also, once you have have of these Camera, you will find many other uses for it, although I would strongly advise against "Home Do-it-Youself Colonoscopy :spaz:
(Seriously, don't even consider that !!! )

Tech just means technician...not sure what the quotes and caps is supposed to imply.

I guess I could get a borescope, but the point I’m trying to make is this is pretty much a non-issue. It’s not something I would ever bother looking at. To keep my resale value high I get the cars dealer serviced at certain intervals, and they could just look then, is what I meant. I’m not talking about scheduling and paying for just a look at carbon deposits.

Yes, "TECH" means technician .. but them what does that really mean .. it's just a title.

Just because you call yourself a "TECH", really means very little, so I was using "TECH" as a not so subtly sarcastic way to imply that the title "TECH" means nothing these days.

Even "CERTIFIED ASE TECH" is not that impressive (at least to me... in reality, it is just a BOUGHT certification, and requires a minimum of automotive knowledge to obtain.)

Just look at the sample Multiple chose sample questions for the test :rofl:

ie
12.

This question has the word LEAST. For this question, look for the choice that would LEAST likely fit the described situation. Read the entire question carefully before choosing your answer.

Which of the following steps is LEAST likely to be necessary when refilling a cooling system?


a. Bleeding the air out of the system

b. Mixing tap water and distilled water

c. Mixing the proper ratio of water to coolant

d. Check the radiator cap for proper fit

Oh jeez. I’m not trying to get into the nitty gritty of who is qualified or whatever. Around here dealership mechanics are called Service Technicians. I'm just trying to say something pretty simple here, and you're recommending new equipment and now you're going into technician certifications. Cut it out haha.

Carbon deposits on DI is no big deal. Try some Top Tier gas if you're worried about it. Get a proper service inspection at recommended mileage intervals and they will look for you and let you know if you need to take any corrective measures.

If your vehicle comes with a turbo it is in your best interest to get a walnut blast. Oil slowly gets into your intake manifold & leaves a residue causing loss of power. Even with a catch can your manifold will still get dirty. Turbo = more maintenance.

I think there are a lot of people with over 100k at this point. I looked at the average mileage of used cars traded out here and it was over 50k miles on a 3 year old civic. Gotta remember, the engine has been around since 2016 at this point. There are a lot of people who buy a Civic as a daily with long runs to and from work. Hell, there was a guy on here back in 17 that already had over 70k miles in 1 year.

If you're worried about carbon buildup in your DI engine, take a look at this AAA study which compared gasoline brands. They found that the detergent in 'Top Tier' brand gas leaves 16x less carbon deposits in your engine. They ran some test cars for 4000 miles on Top Tier brand vs other brands, then took the engines apart. The pictures of the cylinders paint a pretty clear picture. The study concluded that your gasoline brand is worth considering.

I now only buy at Top Tier stations like Shell or Esso just in case. I don't know if I'll ever need a full walnut blast, but I'll have a tech do a scope after I get a few more years on the car.
The test doesn’t tell you if they used DI or port injected engines. Im guessing it’s not DI engines. DI doesn’t spray the intake valve like port injection does. Toyota uses port and DI to clean intake valves, but I don’t know if all models do. Ppl have said Honda tweaked valve and injector timing to get a little fuel mist on the intake valve.
