How to Reassemble a Cylinder Head with New Valves and Components on 2013 Hyundai Elantra?

Question

Accepted Answer

Regardless of whether the head was sent to an automotive repair shop for valve servicing, ensure it is clean before beginning reassembly. If the head was not sent out for service, proceed to the next action; if it was sent out, the valves and related components will already be in place, so begin the reassembly procedure accordingly. Starting at one end of the head, lubricate and install the first valve, applying moly-base grease or clean engine oil to the valve stem before installation into the guide. Install the spring seat and shims, if originally installed, before the valve seals. New seals should be installed on each valve guide, gently tapping each seal into place until fully seated. Many seal sets come with a plastic installer, but hand pressure is recommended; avoid hammering on the seals to prevent them from being driven down too far, which could cause leaks, and ensure they are not twisted or cocked during installation. The valve components should be installed in the following order: valves, valve spring seat, valve stem seals, valve spring shims (if any), valve springs, retainers, and keepers. Compress the springs with a valve spring compressor, carefully install the keepers in the groove, then slowly release the compressor, ensuring the keepers seat properly. A small dab of grease can be applied to each keeper to hold it in place if necessary, and tapping the valve stem tips with a plastic hammer may help seat the keepers if needed. Repeat the procedure for the remaining valves, ensuring components are returned to their original locations without mixing them up. Check the installed valve height with a straightedge and a dial or vernier caliper; if the head was sent out for service work, the installed height should be correct, but it is important to measure valve spring height from the top of the valve spring seat to the underside of the valve spring retainer. If the height is less, it indicates that the valve seats have been reworked past their limits. On specific models, insufficient valve spring height can prevent hydraulic valve lifters from operating correctly, potentially causing the valves not to close fully. In some cases, insufficient height may require thinner shims to restore correct valve clearance, and if the valve seats have been excessively reworked, they must be replaced, or the cylinder head will need to be replaced. After installing the cylinder head on certain models, check and, if necessary, adjust the valve clearances.
