setting valve lash

[dbdragger]

can someone give me a good description on how to set rocker arms. I need to know when to stop torqueing them down. Normal stamped RR. on a 350

just tighten til you feel the pushrod get a little tension, while twisting the pushrod and then half a turn..

This is a hydraulic cam right?

if it is that is how to set it

If you\'re doing it with the engine running, (the safest way for a novice) just back off until it ticks, tighten until the tick stops, and then another 1/2 turn, or full turn, depending on your needs. I\'d say a full turn would be good for a totally stock engine, or one with a cam that you didn\'t plan on pushing to the limit. The racier the cam the looser it is usually set. Problem with the loose 1/4 or 1/2 turn settings, is that it\'s a lot more likely to tick while running.

........ A word of caution, if you mistakenly set a valve too tight, and the valve hangs open, it could damage the valve.
