valve adjustment

I did my lower seals the other day but people told me I need to adjust my valves. How do I do this? Thanks

Question

It's been so long since I have done the valve adjustments. I used his video. Could some one help refresh my memory? In his video, he turned the cam lobe to the opposite of the rocker arm, that means the base circle is up right? With the base circle up and cam lobe 180 down, do you adjust those 2 valves? I think in his video he had the cam lobe down on the intake, and he adjusted the intake right? Those 2 valves are running on that same cam lobe right?

Thanks.

I have found the OEM Honda way the easiest:

Set the engine to #1 cylinder TDC, up mark on cam pointed up, marks on the sides of the cam wheel LEVEL with the HEAD. Adjust cylinder 1 intake and exhaust valves.

Rotate 90, do cylinder 3

Rotate 90, do cylinder 4

Rotate 90, do cylinder 2.

Then I go back, rotate the engine by hand a few times, then check the gaps again, adjust if needed.

Question

Cylinder 1 is the one furthest away from the distributor and next to the timing belt right? I followed the Honda OEM book the first time and I had tapping valve and engine was not as strong. Then I followed his video and the engine felt much better. But the gas mileage seems to suffer a bit.
If the valve too tight would cause the decrease in gas mileage? I am not too sure and I don't want to buy another valve cover kit just to check the valve clearance again.
Thanks.

Yes, #1 cylinder is the farthest from the dizzy. It's funny you say that, I tried his way, got them close. Did the Honda way, and I used .09 & .11 gaps, I never hear a valve. Yes if the valves are too tight your mpg could be affected, the valves open a spilt second before they are supposed to. It can even cause backfiring. You don't need a valve cover kit, most valve cover gaskets are rubber and can be reused, as long as they aren't torn or leaking.

Question

The valve cover isn't leaking or torn but one time I pulled it off the gasket shrink and I have a hard time fitting it back on. I'll check it again if the cover is good. Which way did you use? His way or the Honda's manual?
Thanks.

Question

I don't recall but does the mark "UP" also on the side of the cam pulley or do I have to take the top timing cover off?
Thanks.

If the valve cover gasket hasn't been replaced in the lifetime of the vehicle you're going to have a bear of a time refitting it to the valve cover. Get a new one. If you don't have a Honda dealer near you then see if your parts store can get a Beck/Arnley. They fit very well.

The gasket was replaced at least 3X, once by the previous owner and 2X by me. The first one I did was the Ebay one and it leaks on the back. I bought an OEM one and it has not leak since. It's about 2 years old or less. Think I'll need a new one? The new OEM one is only $10 but without the spark plug upper seals. $25 with the seals. Well, if I can reuse it, I would like to as money is tight right now.
Thanks.

If yours is an OEM Honda that's fairly new you should be okay. You won't know for certain until you've tried to put it back on though.

just to verify, when i rotate the engine and watch for the cam gear to go 90 degrees, i'm unsure which way the gear should be going. I know the Hayne's manual says rotate the crankshaft pulley counter clockwise, but i will be turning the PS gear instead. So i'm not sure which way that would in turn make the cam gear move.

IE i have my timing cover on so can only see the side of the cam gear facing the cylinders

therefor do i move the UP marking 90 degrees towards the front or rear of the car to get to cylinder #2?

Towards the front.
