Firestone could've been the ones to break that spark plug! They seem to like to hire a bunch of reject mechanics. They went belly up at the 2 locations they had near me. Not surprised at all. You do good work! By the way my experience has been that the exhaust valves are usually on the tight side and the intakes tends to loosen up over time.
That's usually what I find also but this one they were all way loose. I'm surprised it wasn't noisy. One of the other spark plugs on that side was also broken the same way almost like it had a 3 cylinder tune up done at one point. Probably done at that Firestone
Thank you. My van is in the shop now. Saying it needs piston rings at 192K. I asked them What is the compression on the cylinder (1 cylinder miss fire #3). They couldn't answer. I'm with you, needs spark plugs and valves adjusted. They are wanting 6K to repair. Thanks again. By the way, it's at a Honda authorized dealership..
They absolutely should be able to answer the question. I have personally had several honda v6 engines with problems like rich and missfire codes that were valve adjustment related and I think shops are trying to take advantage of it. My customer was a long time customer of this firestone I think they are the ones who did the half tune up that led to this issue.
@@coryament Your right. I work for JTEKT. We service all machines that Nissan, Toyota and Honda use for their crank and piston lower power train. I knew when the dealership told me it needs rings, I knew something was wrong. By the way, I had the 100K tune up required by Honda. The dealership told me, when I asked, did you change the spark plugs, they said yes. The dealership it's at now, said the plugs have never been changed. Again. Thank you. TBD.
Great job! I get to do this tomorrow...again I had to repair some valves on Bank 2 due to a broken timing belt pulley bolt...valve/piston contact. I did the valve adjustments with the head off the engine. I think the head bolt torqueing messed with the clearances or I did them too tight. When the engine warms up the misfire happens for all cylinders in Bank 2 and the exhaust starts to suck and blow at the pipe. Also, Bank 1 is louder than Bank 2 now, didn't adjust those...shame on me. Moral of the story...there is always time to do the job a second time when rushing/half-assing it the first time. Thanks!
Good video! Somebody is taking good care of the Odyssey as the engine looks very clean inside! Did it have it's Timing Belt changed? I'm glad you checked everything!!
As someone with 2 Odysseys and looking at doing a valve adjustment on both myself at some point. For the 2013 model, do you still have to make sure the cylinder you're working on is TDC before adjusting or is that only older models? Thanks for the video. Both of mine are running smooth and not exhibiting signs of needing a valve adjustment (which I'm thankful for at this point) but they're both around 165k so I know it's going to happen lol.
@@shadowman1992 not yet, I'm probably 80k over on one van and 50k over on another. I've watched videos on it and, it looks manageable but realistically, I haven't had any issues by not doing it. So, idk.
@mattd1188 yeah and I have actually read and seen many owners who have never done it shoot my mom owns a 07 honda fit with 230k miles and never did anything and runs perfectly. I guess you will get misfires and rough running on a cold start if there is an issue.
Could be anything, timing belt tensioner, VTEC solenoid, exhaust leak or just a bad bearing on one of the pulleys. This is good tip to at least narrow the location down: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-fHtLH_m9gN4.html
Did you do the exhaust side on the rear bank, and the intake side of the front bank? You pointed out the exhaust in the front and the intake in the back, but there is exhaust and intake on both. Intake loosen over time Exhaust tighten. Exhaust are the dangerous ones. They are the reason for burnt valves, not intake. You have to ensure you get both on each head.
I adjusted all of them. I just pointed out the exhaust on the front because they are easier to show. Every valve was way loose but one exhaust that was still in spec.
@@coryament Not sure if you turn the crank by the crank bolt, or cam bolt, but I found it easier to just turn the cam bolt for each cylinder. Since the drag can be hard to get right, I like to do a step process where I go 3 sizes larger and shouldn't be able to insert, 2 sizes is real snug, 1 size is snug, and the size I want is just right.
@@kayjay4060 I use the crank bolt to turn the engine and line up the number on the cam gear for what cylinder to adjust. Honda made it pretty easy. I was surprised to find all were loose. I'm used to the 3.0 that are always tight causing problems.
I think this is a common problem for Honda V6 engine with VCM. The VCM (which shows ECO light on dash panel) will only use 3 cylinders when in use. The intent is to save gas and pass some test to be able to sell the cars. The problem is that the VCM will use more engine oil in the 3 cylinders, it may easily cause misfire (the piston ring foul and spark plug to be replaced). Lots of people disable the VCM with some VCM muzzeler (basically a resistor to fool the sensor).
