How do you check the valve clearance on a Honda CRV?
Special Tools Required
- Remove the cylinder head cover.
- Set the No.
- Select the correct thickness feeler gauge for the valves you’re going to check.
- Insert the feeler gauge (A) between the adjusting screw (B) and the end of the valve stem, and slide it back and forth; you should feel a slight amount of drag.
What are the symptoms of a bad valve?
The symptoms of bad valves include:
- Cold Engine. A cold engine test will give you a good idea if your valve seal is faulty.
- Off-Throttle Braking. Engine braking involves employing different means to slow down your car asides from the external braking.
- Idling.
- Excessive Oil Consumption.
- Excessive Smoke.
- Loss of Engine Power.
How do you adjust Honda valves?
Adjust the valve by turning the bolt clockwise with a flat head screwdriver. It needs to be tight enough to create just a small amount of drag on the feeler gauge. After you adjust it, tighten the nut and move on to Step 4.
When is Honda CRV due for valve adjustment?
The Honda dealer says our 2005 CRV is due for valve adjustment at 108,000 miles. The owners manual makes no mention of adjustment, and I would have guessed the valves were hydraulically operated, so is my service adviser planning on a boat payment or do the valve clearances need to be checked?
Why is my exhaust valve too tight on my Honda CRV?
If the valve/head surface wear rate exceeds the cam-lobe/shim wear rate. Good explanation. Something else that affects valve lash (too tight) is stem stretch and this is the case with exhaust valves more often than not due to the valve spring slamming the red hot valve down onto its seat repeatedly.
How often should the valve lash be adjusted on a Honda CRV?
Fortunately you have a later generation engine that is not as susceptible to damage, but you should definitely have the valves adjusted regularly. Honda recommends that valve lash be inspected at 110,000 miles.
Why do Honda dealers not push valve adjustment?
The reason the dealers don’t push valve adjustment is because it’s somewhat time consuming and requires more skill than the 15 minute flush job. I’ve owned four Hondas (’75 Civic, ’81, ’85, ’88 Accords) and I found valve adjustment to be one of the most satisfying DIY maintenance jobs.
