1989 Acura Legend Cylinder Head Parts Questions & Experts Answers

• Q: How should the Cylinder Head be prepared for reassembly after valve servicing on 1989 Acura Legend?

  A: So, whether the head was carried off to an automotive repair shop for valve servicing, be certain it is clean before reassembly starts. If the head was sent out for valve service, the valves and associated components will be already assembled, so repeat the assembly procedure. Install new seals on each of the valve guides; intake and exhaust valves need different seals (For the exhaust ones, the spring is black, for intake it's white or silver). Slip the spring seats over the guides. To prevent damaging the valve seals when they are seated, gently tap each seal into place with a suitable tool until it is seated on the guide, never knocking the seal after it is on and in each time, and never twist or cock the seal when installing. First valve, begin with one end of the head, lubricate and install the first valve, using moly base grease or clean engine oil to the valve stem. Install the valve spring and retainer with the outer valve spring having the narrow pitch end on the cylinder head and install the valve retainer over the outer valve springs and valve stems. Remove the spring compressors, compress the springs with a valve spring compressor and carefully fit keepers in the upper groove, slowly releasing the compressor and seating the keepers, applying a dab of grease to each keeper if necessary to hold them in place. Repeat the procedure for the other valves but ensure to put the components back into their place without mixing them up. Check the valve spring installed heights of the valve with a dial or vernier caliper on each valve, and finally.
