    My bike is a 2004 XR650L. The top of head has 4 round caps on top. My owners manual says 0.10 for intake 0.12 exhaust Im not sure about how to align crank so valves are seated and all pressure is off springs before I stick feeler gauge in.

The intake valves set at .006 plus or minus .001
The exhaust valves set at .008 plus or minus .001
Remove the rectangular valve access covers at the top front and top rear of the cylinder head. With the engine cold, remove the spark plug. Turn the flywheel to TDC compression then place the specified thickness flat feeler gauge between the top of the valve stem and the adjuster on the rocker arm. Set the adjuster so that there is a slight drag when removing the gauge. There should be a valve adjusting tool set in your tool kit. It is a "pin" that fits the top of the adjuster and an open wrench to loosen and tighten the lock nut on the adjuster.

    Sorry about that. I gave you info on a '04 XR650R. My bad... Remove the four caps. Go with the 10 and 12. Do it the simple way. Pull the spark plug. Turn the crank so that the exhaust valves are open. You can see and/or feel the rocker arm move downward. If the exhaust is open, you know the intake is closed, so set the intake valves. Now rotate the flywheel to a point where the intake valves are open. Now set the exhaust.

08 Civic EX, valves became noisy at60K, valves quiet after warmup. They will probably still be noisy after I adjust them. Would the cause be excessive wear on the valves stem ends and rockers?


If there were no wear, the valves wouldn't need adjusting. The reason for periodically adjusting the valves is to compensate for the wear that the valve train undergoes over the life of the engine. Be optimistic! Have confidence that adjusting the valves will reduce the noisy valves.

What is the clearance between the rocker arm and the valve spring in a GM 2.2L motor


there is no specification for what you want
the valve clearance is between the end of the rocker arm and the end if the valve stem
the stem end is proud of the spring retainer so if your rocker arm is touching the spring retainer , you have a big problem as for the procedure it is set out in the workshop manual but if you don't have a manual it can be done like this
you will need the firing order of the engine first
now adjust no 1 piston valves when the next piston to fire has the valves in the rock position
that is the exhaust valve just closing as the inlet is just opening a bit of movement of the crank makes either valve move up or down
adjust no 1 piston valves
now move on to the next piston to fire and adjust the valves that were rocking
follow that procedure until all the valves are adjusted
for example
on a 4 cylinder engine with a firing order of 1--3--4--2
bring up no 1 piston and adjust the valves when the valves on no 3 piston are rocking
next piston to fire is no 4 so adjust no 2 piston valves
next piston to fire is no 2 so adjust the valves when no 1 valves are rocking
the procedure is the same for engines with any number of cylinders

When the valves are adjusted on the de-compression stroke can they be re-adjusted or is the head now faulty?


valves should always be adjusted with the cylinder being adjusted at top dead center(tdc). if you can rotate the motor by hand you can adjust the valves with no damage having being done.

Need to find out how to adjust vavles


If your engine is an overhead valve Briggs. You need to:
Remove valve cover
Locate rocker arms. Upper is exhaust, Lower is intake.
Loosen the lock screw in the center of the adjusting nut.
With engine at TDC and both valves closed adjust both valves by turning the adjusting nut to obtain proper clearance. Once set, tighten the center lock screw.
Valve adjustment specifications vary from model to model. Would need more engine information to get you that or it can be found online.
Reinstall valve cover, make sure gasket did not get damaged.
Adjust valves on a "cold" engine.

Overhead valves making noise like they need ajusting


Valve Lash ADJUSTMENT 1.6L Engines NOTE: Measure valve clearance with the engine cold.
  1. Before servicing the vehicle, refer to the precautions in the beginning of this section.
  2. Remove the valve cover.
  3. Set the engine to Top Dead Center (TDC) of the compression stroke for the cylinder to be adjusted.
  4. Check the valve clearance. The valve clearance specifications are as follows:
    • Intake valves: 0.005-0.007 inches (0.13-0.17mm)
    • Exhaust valves: 0.005-0.007 inches (0.13-0.17mm)
  5. After adjustment, tighten the locknuts to 11-14 ft. lbs. (15-19 Nm).
  6. Repeat for each valve to be adjusted.
1.8L, 2.0L and 2.5L Engines The 1.8L, 2.0L and 2.5L engines utilize automatic hydraulic lash adjusters to maintain proper valve lash at all times. Periodic valve lash inspection and adjustment is not necessary or possible. prev.gif next.gif
