• Q: How to replace the Rocker Shaft Spring Kit and Valve Stem Oil Seal on the left side on 2008 Buick LaCrosse?

  A: Begin the valve stem oil seal and valve spring replacement process of the left side by taking out the Starter motor assembly. The Crankshaft can rotate if the en 46106 flywheel holding tool is absent which requires you to disassemble and reassemble the entire Camshaft timing system. The en 46106 should be installed as a Crankshaft rotation prevention tool before camshafts and rocker arms removal. Position the j 39313 Spark Plug port adapter through the appropriate cylinder and connect it to an air compressor. Place the en 46110 on-vehicle valve spring compressor directly above the targeted cylinder. Exercise caution as compressed valve springs exert high tension; unprocedural manipulation exposes individuals to possible harm. Keeping the valve springs at a minimum of 24.0 mm (0.943 in) compression protects the valve stem oil seal from damage. Begin by using en 46110 valve spring compressor nut tightening to secure the valve springs in place before removing the valve keepers using en 46117 valve stem key remover/installer. Start by loosening the en 46110 valve spring compressor nut before removing the valve spring retainer and valve spring. The en 46116 valve stem seal remover/installer enables effective removal of valve stem seals. The installation process begins with the en 46116 tool to position the new valve stem seal then continues with the installation of valve spring and valve spring retainer. Position the en 46110 valve spring compressor above the valve spring before tightening the compressor nut with the valve keepers oriented correctly so their tapered ends face the valve stem seal. First follow up by compressing the spring and then use en 46117 to position the valve keepers. Finally detach j 39313 from compressed air and remove en 46110. Following Spark Plug installation, put on the rocker arms and camshafts and remove the en 46106 tool before reattaching the Starter motor.
