Valve adjustment?
Valve adjustment?
I have done a search and have not been able to come up with anything... I am trying to find out how to adjust the valves in my 86 tpi 305. Thanks... Maybe somebody could point me in the right direction for instructions... Any help would be appreciated.
i have had the best luck with removing a valve cover,and starting the motor. Tighten the rockers to quiet the noise, then one by one follow these steps for each rocker:
1)Loosen the adjuster nut till the lifter starts ticking.
2)Tighten the nut till the ticking stops.
3)Tighten the nut 1/4 to 1/2 of a turn farther.
Then do the same for the other side of the motor.
Be aware that this method is messy. It is best to have shop towels handy, and put cardboard under the motor to catch oil.

Actually there are a couple of ways to do things without getting all oily.
I used to have a spare set of valve covers with slots cut in the top when I was working on race cars.
Another way is to put clips on the rocker arms if you are running stockers.
The third way is like the machine shops do. You turn the engine until both valves on the cylinder you want to adjust are closed (back side of lobe). Then wiggle the pushrod up and down and tighten until it just stops wiggling up and down. Then you tighten a full turn. Do that for each valve….
