yes you do
you do not need to remove intake manifold to change valve cover gaskets. intake bolts to the block. valve covers bolt to the heads EDIT: Theirs some clearance issues but you can maneuver the valve cover out.
Remove carburator then intake manifold then cylinder heads
Remove the air intake, throttle cables, and throttle body. Remove vacuum lines then unbolt and remove the upper intake. Remove the fuel rails. Unbolt the lower intake and remove the intake to replace the gasket. Reverse the process to finish the installation.
To replace the valve cover gaskets on a 1998 Mazda Millenia, first ensure the engine is cool and disconnect the battery. Remove any components obstructing access to the valve covers, such as the ignition coils and intake manifold if necessary. Take off the valve cover bolts using a socket wrench, carefully lift the valve covers, and remove the old gaskets. Clean the surfaces, place the new gaskets, and reassemble everything in reverse order, ensuring to torque the bolts to the manufacturer’s specifications.
YES, Remove all old gaskets and replace with the NEW ones.
You have to remove the intake plenum air chamber to get to the 3 plugs against the firewall. It requires to buy intake plenum gaskets and go ahead and replace the PCV hose on the back of the plenum. Need to get from the dealer. Gaskets also from dealer.
You will need to remove the intake and the exhaust manifolds and then you can remove the heads to replace the gaskets.
of course lol!!!
These engines do not blow head gaskets. You need to replace the black plastic intake or plenum. They will leak coolant into the combustion chamber. Some roge mechanics will tell you it's head gaskets to get you to pay more money. Remove upper intake, remove spark plugs to get coolant out and replace and fill with coolant.
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.
i believe so Yes. Maybe your problem is the intake manifold gaskets rather than the head gaskets. What are the symptons?
No, you need a new gasket. About the only gaskets that may be reusable are valve cover gaskets some engines.
