Valve springs Clatter
Im a newbi here, but been looking at tons of post 4 a while. I changed the upper and lower seals on my 93 honda accord 10thAnn, due 2 oil in the spark plug slots. I also did a complete tune up. plugs wires dist.-rotor ect. When i got 2 the part to remove the rocker arm assembly, I stupidly loosend the valve spring bolts. all of them. After i realized what i had done i tighten all of them down. I put every thing together and fired right up! But I her the clatter noise now that was not their at first. Is there away 2 adjust them?

Go to the DIY section & look for a sticky post about shop manuals. Download the one for your car, or near the same year. Valve lash adjustment should be in there.
Each rocker has an adjustment screw with a jam nut. You adjust that to get the proper clearance. But if it's that far off, you might also want to look for something/anything that you may have mis-aligned when putting it all back together.

After you get the procedure from the book you can use a remote starter to get the engine in position for each adjustment. The procedure is using the marks on the cam sprocket to get the cam lobe in its low point. You can use that to verify you have the cam sprocket in the right position. You adjust the valves to feel a little resistance or friction.
The specs for the valve clearance are in metric on the under hood sticker and in a factory Honda manual make sure you get the right feeler blade.

When you do the job just be sure you are on the low spot on the cam for the valve you are adjusting. The cam lobe is egg shaped and the low spot is long enough that you can see it. If the marks are correctly lined up for the cylinder you are adjusting all the rockers for that cylinder should be at rest with clearance between valve stem and rocker.

An easier and safer method is to:
1) Jack the vehicle
2) Put it on axle stands
3) Remove drivers front wheel
4) Remove valve cover
5) Remover upper timing belt cover
6) Grab a 19mm socket, a 1/2 inch ratchet and a very long extension. You can then rotate the crank manualy and with more control to move the cam into position so you can make the adjustments.
Or if it is a manual transmission do steps 4 and 5, put the car in neutral pull the ebrake and rotate the flywheel manually (through the timing access port) with a long flat head screwdriver.
