  1. What is this sticking out by my dipstick?

    I'm sure it'll be fine. I've used rtv sealants in places I probably shouldn't have on old, beater trucks before. It's a great product if you do it right. I just wanted to make sure I didn't inherit someone else's screw up. Thanks for the clarification, I appreciate it.
  2. What is this sticking out by my dipstick?

    Ok thanks. That's kind of what it looked like to me, some kind if liquid gasket which is why I thought maybe someone did it themselves. Lol am I crazy or does it look like something some back yard mechanic would throw together on the farm or something?
  3. What is this sticking out by my dipstick?

    So I recently purchased a 2018 si with 8k miles on it. I've been keeping an eye on the oil level to see if it has excessive oil dilution. I noticed something that I initially wrote off but it's been wearing on me a bit and I just have to ask about it. I've attached 3 images. The first image has...
  4. Carbon buildup on valves in GDI

    I think that one of the things that promotes oil dilution is excessive idling, which 10-15 mins seems to be. Also Honda has acknowledged oil dilution buy they say that some dilution is normal. Actually, if you go over to Google scholar (it's a search engine that only looks for research papers)...

    Nice, this is the kind of info I was looking for, thank you.
  6. Carbon buildup on valves in GDI

    Taking the lack of oem catch can as a sign that they're not beneficial seems a bit short sighted imo. You also have to think of why they might not want to put one in when determining if they're beneficial. The lack of oem catch cans doesn't really seem to prove anything. For one, they need to be...
  7. Carbon buildup on valves in GDI

    I actually do shift at higher rpms in this car than my truck and honestly, as much as I try to not beat on my stuff, the car is just too fun to always drive slow anyway lol. I don't really red line it all that often but the power drops off before redline anyway. It definitely makes me drive...
  8. Carbon buildup on valves in GDI

    That is something that I was also going to ask about but in a different post. Initially when I heard about the oil dilution in the L15B7 I told myself I wasn't going to buy the car. I eventually found out that this was a concern in all direct injection motors and decided to put my faith in Honda...
  9. Carbon buildup on valves in GDI

    I'm fairly new to the car scene and have a quick question about direct injection engines. I have a LOT to learn so I'm sorry if this is a dumb or previously answered question. I bought a 2018 civic si as a daily driver and have been doing a fair bit of research into the L15B7 motor. One of the...
