• | SA9123E Gasket Seal Cutter |
• | SA9123E Rear Crank Seal Replacer |
Important: The following removal and installation procedures are general. Refer to the specific component section for detailed information, including torque specifications.
Room temperature vulcanize (RTV) sealant is used in 6 locations on the engine as a gasket or sealant:
• | The oil pan |
• | The front cover |
• | The rear crankshaft seal carrier |
• | The front cover, cylinder head, cam cover T-joints |
• | The vibration damper/pulley washer |
Important: Disassembly of components sealed with RTV requires that specific procedures be followed. SA9123E is required for oil pan removal. The engine's front cover and rear seal carrier have pry tangs to break the component loose from the cylinder block. The cam cover gasket is a precured gasket.
Important: An 8 mm flex socket can be used to access the rear oil pan bolt heads next to the flywheel on vehicles with manual transaxles.
Refer to the "Lubrication System" section of this service manual for detailed procedures on front cover assembly removal.
Important: Installation of the wood block prior to upper engine torque axis mount removal allows the mount to be easily installed without lifting or jacking the powertrain.
Notice: Spray the two dowel pin holes in the front cover with penetrating oil to prevent cover damage during removal.
Important: One front cover assembly attachment bolt is located under the torque axis mount flange, above the accessory drive belt idler pulley.
Important: Screwdriver slots are provided to pry the seal out of the carrier. Use extreme care not to damage the crankshaft sealing surface. The SA9123E is used to install the seal and/or carrier. The tool prevents rolling the seal's lip.
DOHC (LL0) engines are assembled with black composite cam covers.
Important: Inspect the cam cover isolations for cracks. Replace the isolators if deterioration exist.
Important: Gaskets over one year old may take a set and should be replaced. Gaskets under one year old do not need replacement. A small drop of RTV must be installed at the 2 T-joints whenever the cam cover is installed.
Notice: If excessive RTV is applied, or oil builds up in the blind holes, the casting will crack when the bolts are installed. Make sure all oil gallery openings and the oil pan are covered with a shop towel to prevent debris entry.
Surfaces to be sealed must be clean and dry. RTV is removed from aluminum surfaces using scrapers, wire brush or Scotch-Brite® Pads and disk (3M® Clean-N Strip® 2 in. D x 1/2 in W x 1/4 in center hole).
The cylinder block, head and front cover holes must be cleaned with a 3/16 in. drill and tap handle. The front cover non tapped holes can be cleaned with a 3/8 in. drill.
Important: Refer to specific sections of manual for additional detail and torque specifications.
Notice: Do not use petroleum cleaners such as mineral spirits. They leave a film onto which RTV will not stick.
After all RTV is removed, clean the surfaces with a chlorinated solvent, such as carburetor spray cleaner, brake clean or alcohol Saturn P//N 21007432 or equivalent, and Scotch-Brite® Pad.
Important: Only the Saturn recommended RTV, Saturn P/N 21006236 or equivalent, should be used. Surfaces to be sealed must be clean and dry. Reference appropriate sections for torque valves.

2. | When replacing precured gasket. |
Important: Follow each surface pattern and maintain the bead diameter cross sections required to ensure the joint is sealed.
Important: Apply bead on the inside edge of the groove as shown.
Important: The front cover oil seal drainback hole and passage way must be kept free of RTV to prevent front seal damage. After the front cover is installed. 6-12 squirts of oil can be pumped through the front oil seal drain back hole to make sure it is not plugged.
Important: Extra RTV is required at oil pan, cylinder head and cam/rocker cover T-joints to make sure gaps are filled to prevent oil leakage. The 1992 and later engines require a RTV bead around the top, center bolt hole.
Important: Install a thin film of RTV sealant between the vibration damper/pulley assembly flange and washer only. The washer and bolt head flange are designed to prevent oil leakage and do not require sealant.
Notice: To prevent engine front cover and mount damage, the three front engine mount-to-front cover nuts must be tightened down uniformly.
