Do you have to adjust solid lifters?
All pushrod engines using mechanical (solid) lifters, or mechanical roller lifters, must have an adjustable valve train so that precise adjustment for “Valve Lash” can be made to match the camshaft’s requirements. It is important to use the recommended valve lash when you first test the performance of the engine.
How do you adjust valve clearance?
Hold the post with a spanner while you slacken the locknut, then turn the post anti-clockwise to reduce the clearance and clockwise to increase it. When the gap is correct, hold the post steady while tightening the locknut, then check the clearance. Keep turning the crankshaft until you have checked all the valves.
How do I know if I have hydraulic or solid lifters?
Another way to quickly determine solid or hydraulic lifters is to push down firmly on the lifter end of the rocker arm. Hydraulic lifters will allow for some movement, whereas solid lifters will not budge.
Do you adjust valves at top dead center?
Rotate the engine to the TDC mark, which puts cylinder #1 at top dead center. Rotate the engine 180 degrees in its direction of rotation (usually clockwise looking at the belts). Adjust the valves of the next cylinder in the firing order. Repeat until done.
Do you adjust valves hot or cold?
Major camshaft manufacturers recommend setting valves cold, to avoid erroneous adjustments on lifters that may be “pumped up” If you are setting valves on a fresh engine that has not been run, everything should be well lubricated before you begin. 2.
How often should you check valve lash?
every 500 to 700 laps
On a shaft-mount system, most manufacturers say lash should be checked every 500 to 700 laps. Once you’ve determined that the valve you are checking is fully closed, actually checking the lash is the easy part.
How do I know if my valves need to be adjusted?
When do I need to have a valve adjustment? You should have your valve lash inspected at manufacturers recommended intervals.

What happens when you over tighten valves?
If a valve is over-tightened, it deforms the tubing and the connection. These deformities create cracks and gaps where the fluid can begin leaking out.

How do you adjust the exhaust valve lash?
When the exhaust valve just begins to open on the first cylinder in the firing order, adjust the intake valve by loosening the adjusting nut slightly while spinning the pushrod until you feel lash in the rocker arm. Tighten the adjusting nut until the slack is taken out of the rocker arm and pushrod.
