I just finished the timing belt service on my 2003 Honda Odyssey with 213,000 miles and got to thinking about valve adjustment. The van has never had the valves adjusted. My concern is the Honda exhaust valves tend to go tight and tight valves can cause them to burn up.
I have watched Eric’s J series V6 valve adjustment video and see it’s a bit of work to get the intake manifold off and get to the valves.
My question to you all: do I need to adjust the valves, or can I leave them alone?
Thanks!

I guess it depends on your use of the vehicle. If it is your primary mode of transportation and you wish to insure it keeps running then do it.
Thank you. I am not having any issues. I don’t even see any leaking what so ever from the valve cover gaskets. I was just concerned about exhaust valves going tight and burning. I need the van to last as long as possible. This is my first experience driving a vehicle over 200,000 miles so I start to wonder about things that could go wrong. 🙂
Well, I’d suggest that checking valve adjustment and adjusting valves is two different if similar activities. Anyway, 213K is a lot of miles. The engine might appreciate the attention.
If they’re not noisy, leave them alone. Honda says only adjust if they’re noisy. If you adjust them incorrectly, you run the risk of damaging them. That can be VERY expensive labor wise to fix. If you’re not practiced at valve adjustments, I do not recommend starting with a V6. You’re much better off starting with a 4 cylinder to practice with so you can get the feel first. It’s much easier to go back and correct those. The V6, not so much.
Thanks Eric. I appreciate your knowledge and insight.
One other question: when you did the valve adjustment in the J series video, why did you remove the throttler bode from the intake manifold. Is this easier than leaving the throttle body on the manifold and disconnecting everything from the throttle body?
Thanks again.
Yes. After performing that operation several times I found it best to do it that way. Also, you don’t run the risk of getting the throttle cables wrong. Think about it, with removing it, it’s only 4 nuts. If you remove the cables, it takes forever to get them loose and then you have to put them back in the same spot and adjust them. Me, I just don’t have time for that. This is the ‘flat rate’ way. It is effective and it does work. Once again, I caution you if you’re considering attempting that adjustment. Get it wrong, and you’ll have to take it all apart agin.
Good luck.
