The pistons keep moving for a few revolutions. The valve train stops. If the engine is an interference engine, the pistons and valves can hit each other.
The lifters are made into the rocker arm and are not removable.
well the lifters shouldn't be too tight if they are the correct lifters for your vehicle. if your having problems with your valves opening its probably because your rocker arms are torqued beyond specifications. buy a manual and loosen your rocker arms torquing to specs.
No to the roller lifters in the 2.8 Ford V6. The 2.8 as well as the 2.9 has regular flat tappet lifters and regular rocker arms.
Typically hydraulic lifters don't get adjusted, they just get tightened to the rocker stud.
The 2.8 v6 produced up to around 1985 had solid lifters with adjustable rocker arms.
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.
It's not recommended to change just the lifters. The cam and lifters should be replaced together. To get at the lifters, you can remove the rocker covers and intake manifold, loosen the rockers enough to get the pushrods out, then pull out the lifters.
Rods and Rocker arms were the problem with my Malibu after changing lifters
There is no adjustment- the engine has hydraulic valve lifters.
through the lifters then through the push rods
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.
remove intake manifold and rocker covers. loosen nuts on rockers and remove pushrods. lifters should lift right out of their bores.
