    Is this missing a bolt? Cam housing/valve cover oil leak

    By johnnyK

    I have a small oil leak and think it’s coming from either the cam housing or the valve cover. When my mechanic was looking for the source he noticed that under the high pressure fuel pump, there is possibly a missing bolt that looks like it may be the back corner of the cam housing. Trying to see if anyone can send a pic of this area of their L15b7- or confirm if there is supposed to be a bolt and if it is one that would go all the way through to torque on the housing. For now seems like... Is this missing a bolt? Cam housing/valve cover oil leak

    Popping sound from front end.

    By TonyTheTiger57

    I have a popping sound that has gotten worse in the front end that is mainly on the passengers side. I have an anti lift kit installed. Eibach swaybars. New HFP struts. And Whiteline adjustable ball joints. The noise happens as soon as I drive in a forward or reverse position. The sound will happen as I jack up the car. I’m conflicted if it’s the CV shaft or control arm bushings. It sounds like threaded rod slipping through a metal hole. I don’t hear it during a drive or while hitting a...

    FK8 Exhaust on FK7 - Resonator Delete?

    By Lycoris

    Hi everyone! I just swapped an FK8 exhaust onto my FK7 and I like how it looks but the volume increase leaves a bit to be desired. Yes, I know I could've gotten a different aftermarket cat-back but I picked it up for $150. I'm trying to look for some sound clips before I roll up to the shop and start asking them to start chopping things off since I'd like to avoid things getting too drone-y. I know a lot of people have deleted both resonators and even gotten rid of the resonator by the... FK8 Exhaust on FK7 - Resonator Delete?

    Best online site for Accord Sway Bar End Links?

    By cammyfive

    I'm ordering the Whiteline 22mm RSB for my 2020 Si and have read that the aluminum Accord sway bar end links are a worthwhile upgrade and cheaper than the end links from Whiteline. Can someone direct me to the part number for the Accord end links and the best Honda online site to purchase them from? Thanks!

    Crazy tire experiment to go with crazy oil experiment

    By Honda202065

    I've hinted I'm running a long term oil experiment. Running 0w-20 for 6,500 miles with full blackstone analysis as well as fuel economy (complete), then 5W-30 for 6,500 same (complete), currently running 05W-40, same (underway), will then run same on 05W-50. I think I know the answer but the data will be the answer. Note I would not recommend running 50 weight in anything other then a 200k plus motor with factory oil pump gears, they will shear at high rpm and oil pressure. I run Boundary...

    2016 Honda civic making clanky noise

    By TelevisionPrograms

    My civic started making these weird clanking noises yesterday. Seems it happens at low speeds especially when I am steering left. The noise doesn’t happen going over bumps or breaking or turning. It’s usually the worst whenever I am pulling into my apartment building which has a slight bump and requires me to make a left turn. Any idea what might be causing this? I recorded the noise here. https://we.tl/t-025E6QwPa15GugXD ... 2016 Honda civic making clanky noise

    KNOCK CONTROL absurdly high, and PSI (TC) not reading

    By courrey

    Hello everyone, I’ve currently run into a couple of issues regarding my 2021 Hatchback Sport 1.5. Some insight, I’m running PRL Intake Race MAF, catless downpipe and front pipe, and intercooler, tuned on phearable 1.5. The tune itself recommends you run 93 octane but I live in california so my options were limited so I tend to pump 91 with a 1.5 gallons of e85. Recently out of the blue, after being tuned for over a year I noticed my knock control was incredibly high at 1.3 idling, and... KNOCK CONTROL absurdly high, and PSI (TC) not reading

I won't need to drive your car at all, just will be plugging into your wiring harness and taking measurements, etc. My product is a digital audio integrator for Hondas, allowing you to install a high end sound system while retaining all factory head unit and steering wheel functions.

    Weird question… are there any open-concept center console guides/kits

    By jimmorrison

    I was messing around with my shifter yesterday and something fell into the void under the center console so I took it apart to get it out, but I kinda like the look of the interior without the center console stack in the way. I was wondering if there are any kits or whatever that let it stay this nice open look but still allowing you to keep all your shifter-area buttons and whatnot connected while looking nicer than a ripped apart dash (pictured)

Installed a couple nights ago and everything was fine till yesterday afternoon. Stft jumping up to the 30s. Coming down to idle stalled the car once . I scanned last night and no codes. So tried again today driving to work. Seemed ok. Sounded a little different. When I came home from work though, I felt the stalls when... Mass Airflow Fiasco!!!

    HKS Blow Off Valve Fitment w/ PRL Turbo Inlet Pipe Upgrade Installed

    By Slim

    Ok so I have a 2018 Civic Hatchback LX with a 1.5T. I have a PRL cold air intake with a turbo inlet pipe installed onto it. I want to get the HKS blow off valve with the adapter piece for my car but the Turbo Inlet pipe upgrade moves where the blow off valve would go and now its closer to the A/C line. Or could I possibly move the a/c line if it does get in the way or rub on the part? Does anyone have both of these upgrades or one or the other that would be able to help out. I assume I can...
