  Q: How to replace the Rocker Shaft Spring Kit and valve stem oil seal on GMC Terrain?

  A:

  The process of replacing the Valve Stem Oil Seal and valve spring needs these specific tools: valve guide seal remover (EN-36017), valve spring compressor (EN-43649), valve spring compressor adaptor set (EN-43649-10), and flywheel holding tool (EN-43653). Keep the Crankshaft stationary before you start working with compressed air in the cylinder space. Manual transmission cars should stay in first gear while depressed on the parking brake. To access an automatic transmission you must take out its Starter unit first. Place the flywheel holding tool (EN-43653) first before removing the Camshaft and Camshaft roller followers. Insert the valve spring compressor adaptor set (EN-43649-10) onto the cylinder head before positioning the cross bars and locks of valve spring compressor (EN-43649). Plug the Spark Plug holes and connect an air hose adapter onto the Spark Plug port. Inflate the cylinder to 690 kpa (100 psi) with the air pressure source. Pressurize the cylinder at 690 kpa using the valve spring compressor (EN-43649) and then use it to decompress the valve spring. The valve guide seal remover helps to properly install a new valve seal by pressing it fully against the working surface. Put back the valve spring and retainer while compressing the spring once more and adding valve spring keepers. Unplug the air hose and take out the valve spring compressor tool model en-43649 and its matching adaptor set en-43649-10 from the engine's top. Put back the spark plugs and put the Camshaft roller followers and Camshaft unit together. If needed install the Starter once you have taken the flywheel holding tool (EN-43653) out of your vehicle.
