Has anyone had either of these services done on their HCH I yet? I was wondering how much a dealer charges, or if it's not so tough to do yourself? Anyone have the Service Manual and can see if it looks more difficult than any 'normal' 4-cyl. OHV engine? 130,000 miles on my '04, I'm thinking it's about due for both

As mentioned in another thread, the HCH has a timing chain, not a belt.

I thought the valve self adjust as well. Have to confirm that though.

I did not know HCH I has timing chain but first valve adjustment should be due by 110K if I remember correctly.

When I bought my 2004, I was told it had gears, but definitely didn't need servicing in any event

I have a 2004 HCH MT with 115000 miles. Just adjusted the valves myself at 110000. They adjust just like any other car with solid lifters. If you have ever adjusted the valves on any other car, you will not have any trouble adjusting the HCH valves. In fact it is easier, each cylinder is numbered on the cam sprocket. Just turn the engine over until the cylinder number you want to adjust is on the top of the sprocket then adjust that cylinder. Turn the engine over again to set the next number is on top etc.

Cool. Thanks md!

What is the valve lash setting? Is there a maintenance manual avilable for the HCH-I?

Valve Clearance:
Intake: 0.15-0.19mm (0.006-0.007inches)
Exhaust: 0.24-0.28mm (0.009-0.011inches)

Yes, there is a manual - the local Honda service dude was kind enough to copy the Valve Clearance Adjustment page with specs for me. I have NOT seen a manual available to the puplic yet. I'm sure you can order one from your local Honda dealer.

I'll try to remember to take pics this weekend as I do my valves. It does look straight forward.

I did my valve adjust last night on my '04 HCH (MT). Pics to follow. It was a piece of cake. Just like mdline stated, the cam gear is labelled for each cylinder, which made things very simple. I removed the covers, coils, front 4 spark plugs, jacked the right side front tire up, put the car in 4th gear, and just rotated the tire until the # cylinder I needed showed on top of the cam gear.
About HALF of the valves needed adjustment (all loose). That kind of surpried me. 131000 miles. Alls good now. I'll see how/if it affects my mileage.

Tools needed: 10mm wrench or socket, flat tip screwdriver.
Time needed: 1hr.
Total cost: $0
