Adjusting valves on CRX Si
I started doing this job @ 4:24PM and finished at 6:10PM, so considering I worked on CRX-es first time, I would imagine I can do this job next time in 40 minutes without rushing myself. Just to let you know
on how much time you have to have in reseve.
Pictures below are in chronological order with more explanations on the page that is linked to every picture.
How Engine works?
Starting work. First removing spark plug wires and letting go clutch cable from the brackets screwed to the valve cover. |
Valve cover removed. I've found a bit of resistance as rubber guides for tightening nuts were glued to the bolts. It's probably a good idea to buy new rubber seals for those bolts, but you can change them anytime later. Honda ATV Service ManualsHigh Quality Online manuals, fast download

Pictures of the cam shaft. Cam is in pretty good condition, no wear. |
I removed spark plugs so I wouldn't have compression resistance while turning the engine and to check them. On the picture plugs are in order from left to right 1-2-3-4. In my opinion they show good mixture and no engine problems. |
I used rachet to spin the engine bu the cam shaft. I didn't use any manual to find the right piston position for each valve. I just looked at the cam to make sure rocker arm lays on the lowest part of the cam lobe. |
I used my old gauge to measure the valve clearence. I welded a ball to the wisegrip and connected it with the gauge. The only requirement was to set the gauge in paralel with the valve to measure true clearance. |
It is always a good idea to cover the opened engine when you're not working on it, say you went for a cup of coffe. |
Setting new gaskets. I used a little bit of silicone gasket to make sure there will be no oil leak (I didn't have one before). |
All parts back in-place and engine is working. No valve knocking anymore. I let it warm up and took a drive. No knocking on any RPMs. |
That is all the tools I used... |
A couple suggestions:
- Use proper tools and make sure you have an idea of how the engine works
- Make sure you know all technical specifications before you start the job and torque specs for the bolts and nuts you will remove/install in the process. i.e. overtightening may result in permanent damage and/or bad performance/lost time.
- Keep your engine and surrounding area clean while you work on it
- Count number of parts/bolts/nuts before and after you work on your engine and if something missing or you've got a few "extra" parts left - make sure they're not inside your engine loose

Have never seen this tool before wondering if it is available in the USA
