  Q: What tools are required to service and repair the valve guide seal, specifically for valve stem oil seal and valve spring replacement on Buick Rainier?

  A:

  To repair and service the Valve Stem Oil Seal for Valve Stem Oil Seal and valve spring replacement you will need valve stem seal remover and installer (J 38820), Camshaft sprocket holding tool (J 44222), valve spring compressor (J-44228-A), and crankshaft balancer remover (J 44226). Start by arranging all valve train parts during disassembly to help you put them back together correctly. Set air pressure to 50 psi first and then activate the cylinder but keep the crankshaft from moving. Support the vehicle at its height and take out the torque converter access plug. Mount the j 44226-3a holding bar to the torque converter bolt to stop crankshaft rotation then let the vehicle down. Place the j 44222 head immobilizer on the cylinder to protect Timing Chain parts before placing horizontal bolts into the Camshaft sprockets for proper chain tension. Rotate sprockets and Timing Chain off camshafts while removing Camshaft cap bolts plus storing the caps neatly for reassembly. Place Camshaft caps and camshafts aside before you use a proper adapter to blow air into the cylinder. Use j-44228-a device to compress the valve springs followed by key removal as the next step then take out valve spring retainer and spring. Use tool j 38820 to uncover seals from the Cylinder Head while preparing to check its condition. Before setting the valve parts slippery clean engine oil goes on valve stems. The j 38820 tool helps install valve stem oil seals then valve spring and retainer go on. Reapply the valve spring pressure using j-44228-a and position the valve keys properly before taking off the compressor. Lower cylinder pressure and apply clean oil to the camshafts. After that slide the camshafts back into their normal positions. Bolt the Camshaft caps into place before clamping them to 12 n.m (106 lb in). Line up the Camshaft sprockets onto their positions before taking off j 44222. Attach a new intake Camshaft washer and bolt with an exhaust Camshaft actuator bolt. Tighten the intake bolt to 20 n.m (15 lb ft) first and perform additional 100 degree tightening with j 36660-a. Begin with 25 n.m torque on the exhaust Camshaft actuator bolt before applying the j 36660-a tool two more times for a total final adjustment of 135 degrees. Reinstall the Spark Plugs and Camshaft cover then support the vehicle again.
