On the v6, yes
The PCV valve plugs into the rocker arms cover or intake manifold.
need torque specs for 3.4 pontiac grand am intake and rocker arms
The valve covers and rocker arms need to be removed as well as the intake manifold. Then remove the push rods to gain access to the lifters.
for the rocker arms bolts its-- 98 and later, step 1- 168 in-lbs. step 2-- rotate an additional 30-degrees. this is all for a 3.1 v6, the intake bolts are -- (lower) step 1, 62 in-lbs, step2, 115 in-lbs, intake manifold bolts/studs(upper)---18 ft-lbs,
I replace the heads with first starting by draining the coolant then removing the exhaust as neccasary then the intake manifold and distributor then the valve rocker arms and pushrods then unbolting the heads.
To replace the valve lifters on a Cavalier, remove the intake manifold, valve covers and rocker arms. Remove the heads of the lifters using needle-nose pliers.
16 8 exhaust and 8 intake
The best way to tell if the valves are closed is to observe the rocker arms. When they are both at the top of their travel, valves are closed. Feel the rocker arms and try to move them, if they move their at the top of their travel.
Check the oil. Failed lifters/rocker arms would not be uncommon.
Yes they can depending on which ratio rocker arms you get.
to adjust the rocker arms you have to either tighten or loosen the top bolt on the rocker arm/arms that need to be adjusted. there is a specified torque for the rocker arms that you should follow to help you adjust the them
V-8 engine has 16, 8 exhaust and 8 intake. V-6 has 12 6 exhaust 6 intake.
