Cylinder head — assembly (Opel Omega B2)

1. Lubricate the valve stems and insert them back into place (see illustration). If new valves are installed, they are inserted into the places where they were ground.



2. Working on the first valve, install the spring support. Dip the new valve stem seal in engine oil, then carefully push it through the valve stem onto the guide. Use a suitable socket or metal tube to seat the seal onto the guide (see illustrations).









3. Install the spring on the support, then the support cup (see illustration).





4. Compress the spring, insert the crackers into the recess in the rod (see illustration). Release the puller, then repeat the procedure on the remaining valves.
