Chrysler 68141352AE Head&Valve-Cylinder

Place a new or cleaned WT filter into the cylinder block, apply RTV sealant at the timing chain side ends, and position a new gasket and the cylinder head.

Position the new gasket over the dowel pins, carefully place the cylinder head on the engine block, and install new cylinder head bolts, tightening them without applying additional oil to the threads.

Loosen the lug nuts on the right front wheel, raise the vehicle, and support it securely on jackstands before removing the right front wheel and drivebelt splash shield.

Install the lash adjusters and rocker arms in the cylinder head, followed by the camshafts, and then install the primary timing chain and sprockets.

Carefully place the heads on the block without disturbing the gaskets, coat the head bolt threads with engine oil, and install them in their original locations.

Position the new gasket over the dowel pins in the block, ensuring any markings are facing the correct direction.

If the height exceeds specified limits, shims can be added under the springs to correct it, but do not shim the springs to the point where the installed height is less than specified.

An appropriate size tap should be used in each threaded hole to remove corrosion and thread sealant, and compressed air should be employed to clear debris while wearing eye protection.

Next, take off the valve covers, followed by the rocker arms and pushrods, ensuring all parts are kept in order for reinstallation.

Using a breaker bar and the appropriate sized socket, loosen the cylinder head bolts in 1/4-turn increments until they can be removed by hand, following the reverse order of the tightening sequence to avoid warping or cracking.

Check for any damage on the mating surfaces.

Yes, 1987 and 1988 four-cylinder engines use different head gaskets than 1989 and later models, which are not interchangeable and require different tightening torques.

Using a new cylinder head gasket, outline the cylinders and bolt pattern on cardboard, indicating the front of the engine, and punch holes at the bolt locations.

When installing head bolts, applying clean engine oil to M10 bolt threads and hardened washers (if equipped), with the chamfered side of the washers facing the bolt heads, is recommended. For M8 head bolts, thread sealant should be applied to the bolt threads.

Remove the banjo bolt, sealing washers, and the fuel line from the rear of the head, then remove the fuel injectors. Remove the rocker housing and gasket. Loosen the head bolts in the reverse order of the tightening sequence, inserting each removed bolt into a cardboard template to keep track. Carefully pry between the head and block to break the gasket seal, then lift off the cylinder head, either with an assistant or using an engine lifting hoist. Inspect the head and remove any wiring harnesses or ground cables still attached.
