Chosen Solution
I tried following the repair procedure in the chilton’s repair manual but now the engine has a distinct ticking sound coming from the engine valve cover area that I did notice before. The repair started with replacing the valve seals because of a lot of smoke during initial start up that eventually went away after running the truck for a few minutes.
Rick, bit of a pain and can get messy :"
- Warm-up the engine and remove a valve cover.
- Restart the engine and let it idle (as slow as possible to prevent massive amounts of oil splashing around)
- Loosen an adjuster nut until the lifter clacks. Go a bit more so that the lifter can fill itself with oil. SLOWLY turn the nut back down until the clack diminishes then stops.
- Go 1/4 more turn and move on to then next valve.
- Do this for all 8 valves then go back and turn them ALL down 1/4 more turn each.
- Do this one more time so that you have a full 3/4 turn of pre-load on the lifters. Sometimes, 5/8 is better than 3/4 so only go an eighth of a turn on the last go-around. Repeat the procedure on the other side. 7.Stock lifter settings are usually 1 full turn. The looser you leave them, the better top end you’ll get and it’ll help the exhaust valves stay a bit cooler as well.
- The reason you only go a quarter turn at a time is to give the lifter a chance to stabilize. Otherwise you’ll stall the engine if you try and crank the full 5/8 or 3/4 turn in all at once. from here Check on here to see how to do it without running the engine. Hope this helps, good luck.
