Issues After Lost Motion Spring Recall
Doubt that, these are more likely being collected to get credit back from their supplier. Also knowing the purchasing strength of Honda, they are collecting to document the number of recalls performed. The supplier will share in the recall labor costs if they ever want to sell to Honda again.
Good idea. The Fit doesn't have the quietest engine to begin with. Actually I would prefer to hear a little valve noise than not. An overly tight valve clearance will be quiet but has the potential to cause serious engine damage. A slightly loose clearance may cause some noise but no damage.

Think of those millions of parts. Well, not on the LSM recall, but across the line totals...
Thanks everybody for your opinions on my particular noise. It is actually very slight, so I think I'll just roll with it. Everything else is okay, just gotta check the fuel economy.
Good luck with your family, know.

Good point, my service advisor said the exact same thing. The bottom line is I now hear a distinct tick-a-tick from my engine (clearly audible from inside the cabin) which was not there before. I think I'm making the right decision by having them adjust again.
No issues from the recall work. Fuel economy and power are much better than before the recall. Got 40.1 mpg driving from southern VT to the Southern Tier of NY. Even up some large hills it didn't shift out of 5th at 65 mph, and pulled all but the steepest hills at 60-62 mph.
There are a few noises that weren't there before, including a very faint whine I'm assuming is the transmission. The engine is very quiet at highway speeds, easily droned out by the tires.

better safe than sorry
The clearances are supposed to be set (by service manual procedure) when each cylinder is at TDC. The cam sprocket has a TDC mark for each cylinder and the engine is supposed to be rotated by hand through the firing order sequence. So it's find #1 TDC, set those 4 clearances, turn the engine to #3 TDC for those 4, then #4 TDC, then #2 TDC.
There is a very narrow range specified. intakes .006 - .007 and exhausts .010 - .012. and therefore very little variation in noise expected. If the valves are noisy, that means the clearances are too loose, and the rocker roller is being slapped by the cam lobe. There is a very small contact angle at proper clearances, and it gets much larger if clearance is outside the range.
As someone else has pointed out, setting manual clearances takes a particular skill to get it right and do it quickly, too. The feeler gauge should be a consistent sliding fit AND should be rechecked after tightening the locknut for each valve. That's because tightening the locknut also tends to tighten the adjusting screw. Personally I prevent that by leaving the feeler gauge in there, holding the adjusting screwdriver in the same position, and tightening the locknut with the wrench, all at the same time. PITA and wish I had 3 hands sometimes. FWIW

If you can hear the valves from inside and you couldn't before, then they are almost certainly too loose. Valve clearance adjustment procedure is verrry tempting for a tech to short-circuit or skip steps to get the job done faster.

clatter noise
Just had my Fit done and the engine now clatters loudly and it seems to shake at idle once warm... I can feel it through the seat and floor boards now... not happy at all. It was perfect before. I have an appointment to have it looked at tomorrow and I really hope they will fix it properly this time. I assume the tech did a sloppy job and skipped steps.
Well, keep in mind that you'll probably hear everything that went wrong but very few of the stories where everything went without a hitch. In any case, not doing the recall work does not seem like a good option IMHO.

I had my springs replaced today under recall. The valvetrain sounds a lot better, I didn't realize how much it sounded like a k-car before.
No clips broken, but two were smashed under the cowling and not engaged. Easily fixed that myself. Windshield wipers were in the same position thankfully.
Dealer tried to upsell ~ $350 of unnecessary maintenance with under 20k miles, I declined, I follow the maintenance minder and DIY.
Overall okay experience, Honda stands behind their cars well.

Hard to tell....people here are generally going to be more aware and observant than the soccer mom who will never open the hood or the ol' geezer who just believes whatever the service writer says. On the other hand, what's coming in here makes me wonder if the odds of having a problem from taking the car in are greater than the odds of having a problem from NOT taking the car in....particularly for low mileage, gently driven cars.
I'm not quiiiite that brave, because if Honda decided to do a recall with cars being no older than 09s, then there might be a lot more significant risk in a few years.......but ideally I'd like to just wait till parts are available and do the frikkin' thing myself. I will NOT be under any pressure to get it done in 1.6 hours....!!!!!!

All Honda dealers received an email from American Honda on 4/8/11 which acknowledges and addresses many of the LMS recall issues within this thread.
The original HSB#11-010 has been revised effective 4/9/11 to address the specific areas that dealer technicians are having difficulty with (cylinder head cover gaskets, rocker shaft bolts, cowl covers, and cowl clips).
HSB#11-010 has nearly two new pages worth of additional procedures and details, and a 'Tech2Tech' video was released yesterday 4/11/11 to demonstrate all new procedures. I have copies of everything (except the video), but just tell your service advisor to check their email!

^^^regarding the above post........
i wonder if honda considers this whole recall a giant cluster-fook.... or just a situation that needs some tweaking.
if this forum is any indication, this recall has not gone well.
i realize the internet can inadvertently exaggerate reality, but....

It shows that Honda is watching and listening. And hopefully there will be some reinforcement of the service manual procedures, too.

You got that right!
