Has anyone adjusted their valves? (GE8)

Maybe we can make a specific thread for the GE? What do you guys think?

Reason is even though it is the same exact engine as the GD, GE8s may have different engine tightening torque specs as the result of some updated valvetrain components.

 

This would be great. We need to have the proper way documented to adjust the valves since the dealers are screwing it up on the motion spring recall.

 

I could see this being an issue on a car with 100k miles or so, but with newer cars like this there wouldn't be any reason to adjust them. I didn't see anything in the manual for that being a service, nor in the honda maintenance schedule.

If you were ragging the crap out of it, maybe you'd want to check the lash after 50k miles just to be sure, but honda cars aren't known for having the lash go out of adjustment.

Some people for just a tick more power will adjust them tighter, but you run into wear issues sometimes.

 

I guess ours were out of adjustment. We had our Fit in for the LMS recall. Part of that includes a valve adjustment. After the recall and adjustment, the Fit had a lot more power and better fuel economy. This was at 37,500 miles.

So it's not an issue for only old cars. I'm going to make the valve adjustment an annual maintenance item, like rustproofing.

 

If you're really interested invest in the factory Service Manual - it's well documented there and the manual is also a tremendous reference for anyone digging into their Fit.

Regarding Honda Service and the GE8 Fit:

Valve Clearance (cold)
Intake 0.15－0.19 mm (0.006－0.007 in)
Exhaust 0.26－0.30 mm (0.010－0.012 in)

Service limit is when outside the range.
How do you tell?
From Honda; "Adjust valves during service only if they are noisy."

A thread on the GE8 valve adjustment procedure would be a good thing if anyone chooses to DIY a valve adjustment.

I haven't read up on this motion spring recall. Though if the service procedure calls for a valve adjustment afterward, I'm sure they were out if the part was related to valvetrain.

I'd say checking them yearly is a complete waste of time, but I'm probably pissing in the wind here.

 

It's interesting that it is part of the recall procedure. My car is currently sitting at my local dealership overnight so they can do a valve adjustment tomorrow. It's been quite noisy since I had the recall done a few weeks ago, and the dealership said that because the engine needs to be completely cold (as in not recently driven at all) to do the lash adjustment, I should leave it overnight so they can do it first thing in the morning.

I say this is interesting because when they did my recall work, they started working on it right away after I dropped it off, and they got it done quickly enough that there's no way the engine was cold by the time they were done. They must have done the valve adjustment on a still somewhat warm engine, hence my noisy valve train.

 

You would have needed to leave it overnight for them to do a cold valve lash adjustment. Soak time should have been between 6-8 hours.

 

Got my car back this morning, and the noise is calmed. It's back to sounding smooth like it did before the recall work.

 

I dropped my car off at 8 AM, and picked it up at 2 PM when the LMS recall was performed. The service writer told me that most of the time it would be simply waiting for the engine to cool enough to adjust the valves properly.

We've put a thousand or so miles on it since our LMS recall was done, and no problems to report. The valves seem to be adjusted just fine.
