I just had the 50K km service done on my 2006 and the "inspection" was just an audio one. "Valve Inspection" was written on the work order and checked off in my service book so I guess I'm covered under the extended powertrain warranty, but that only has 6 months left, so its kinda academic anyway. My dealer service department has never done an actual inspection in the last 5 years, I'm not sure I'd want mine to be their first.....

Haven't decided what I'm going to do in the future (75-100K kms). I guess eventually the actual valve clearances will have to be measured.

I did my 1st adjustment at 30k miles, skipped them on 60 and did them at 90k. so as you can see an "audible" check isn't worth a thing. I haven't done a mileage check, but in my past experiences, it does affect fuel mileage, and at the way gas prices are going up........
Anyway, just thought I would throw this out there for you all to make your own decisions on whether to do it or not.

It's great that you reported back on this. Sounds like you did the work yourself. Is it difficult? Do you have a background doing this sort of thing? Is it really a $1000+ job?

Do you think the misadjustment could be diagnosed using electronics and scanning the exhaust gases?

Thanks!

Yes GEEVEE, I do have a mechanical background. I dont know what book time is, but it took me about 6 hours to do the job, not including the trip to get parts. At what it took me, plus parts, I could easily see 750.00 + (95.00 hr + 150.00 parts, tax, extra ?....)

Adding some experience to this sticky...

Having some simple hands on experience with motorcycle valves and shims, I spent the money and had my dealer fully inspect and adjust the valves to specification at the 50,000 km point on my Canadian 2009 2.4l I4 GV. This is early by the new maintenance schedules, but normal for extreme use. I regularly tow 2500 lbs so extreme it is.

Four out of sixteen needed to be brought into specification, mostly exhaust. I had the technicians record the measurements for posterity. It is my hope that this J24B engine with attentive maintenance will last as long as the J18 I had in the Sidekick Sport.

In my opinion, the $300-500 it may cost to do this work will be worth it if you plan on keeping the vehicle a long time as I do. The first inspection and adjustment is usually the most important.

This massive thread has apparently ran its course. Should one need to post relative supporting remarks on the subject matter, please start a new post or PM a Moderator to add information inclusion if specifically relevant to this thread.

Default Edit: An up-date from member Geevee w/ a potential future inspection option

2nd Gen GV Valve Inspection/Adjustment

"At 98,000km I've just had this done on our '06 with the 2.7L engine. The (independent) mechanic reported that only two valves were "out", and by only .002". He is very knowledgeable about this sort of thing. He said that the way the valves on this engine can get out of adjustment will affect performance, but not result in damage. They open or close late instead of early or something like that. Because these modern engines have all sorts of sensors, the engine computer is aware something is out of adjustment, and I assume there is an on-board exhaust gas sensor. The engine computer compensates for that variance, and increases the compensation as the variance gets worse.

Using an exhaust gas analyzer and/or checking the engine codes, and then performing the adjustments, my mechanic and his staff are developing a table that correlates variance in the engine parameters or exhaust gases with the amount of shimming that will be required. This means that eventually you can learn whether your engine needs this adjustment with a simple check instead of taking the engine apart.

This is not unique to this engine, lots of Honda vehicles require the same inspection and adjustment."

To be fair, there are people who have posted here who seem to know what they are talking about, who say out-of-adjustment valves cannot be detected by the method described by my mechanic. I don't know enough about these things to judge who is correct.
