- Tools Required
- SA9103E Regulator Valve Remover/Replacer
- SA9104E Front Crank Seal Replacer
1. Clean the front cover, cylinder block and oil pan mating surfaces:
NOTICE: If excessive RTV is applied, or oil builds up in the blind holes, the casting will crack when bolts are installed. Make sure all oil gallery openings and the oil pan are covered with a shop towel to prevent debris entry.
a. RTV is removed from aluminum surfaces using scraper, plastic or wood, Scotch-Brite Pads, and disk (EMU Clean-N Strip 2 inch D x 1/2 inch W x 1/4 inch center hole).
b. The front cover, cylinder head and block bolt holes must be cleaned with a 3/16 inch drill and tap handle. The oil drain back hole must also be free of RTV. The front cover non tapped holes can be cleaned with 3/S inch drill.
IMPORTANT: Do not use petroleum cleaners such as mineral spirits, they leave a film onto which RTV will not stick.
c. After all RTV is removed, clean the surfaces with a chlorinated solvent, such as carburetor spray cleaner, brake clean, or alcohol.
NOTICE: If removed, the oil pump must be packed with Vaseline petroleum jelly for priming.
2. Install oil pressure regulator and pump cover if REMOVED. Install the regulator using service tool SA9103E and a hammer. The pump should be installed with the chamfer toward the front oil seal.

a. If front seal was removed, use service tool SA9104E to install a new seal. Never tap on the seal or seal installer with a hammer.
b. Install new oil pressure and suction seals into their respective cavities in the cylinder block.
NOTICE:
- The front cover, oil seal drain back hole, and passage way must be kept free of RTV.
- Extra RTV is required at oil pan, cylinder head to block, cylinder head and cam cover T-joints to make sure gaps are filled.
c. Apply a 4.0 mm (0.158 inch) bead (refer to the RTV) on the front of the oil pan and a 2.0 mm (0.079 inch) bead on the front cover. Apply RTV around the front cover top, center bolt hole. Install cover immediately.

30. Fill with coolant. Use only DEX-COOL(TM) ethylene glycol-based antifreeze.
IMPORTANT: Vehicle must be level when filling with coolant.
31. Prime fuel system.

b. Repeat step a twice.
c. Crank engine until it starts (maximum starter motor cranking time is 20 seconds).
32. Start engine and check for leaks.
IMPORTANT: Allow the engine to idle for three to five minutes. If lifters are noisy or cylinders are misfiring, warm the engine up at a low rpm (less than 2,000). After the coolant temperature has reached approximately 85° C (185° F), cycle the engine rpm from idle to 3,000 for approximately 10 minutes or drive the vehicle five miles to purge the air. If the air cannot be purged, the faulty lifters will have to be replaced.
Lash adjusters that are pumped up may cause Powertrain Control Module (PCM) misfire codes to set. Continue to operate the engine until the lash adjusters bleed down. Using the PDT, clear codes and malfunction history.
33. Perform a three mile road test.
34. Fill the cooling system surge tank to the FULL COLD line and check for leaks after the engine has been tested.
