16. Front Cover and Component Assembly

- Tools Required
- SA9104E Front Crank Seal Replacer





1. Clean the front cover and cylinder block 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 a plastic or wood scraper, Scotch-Brite Pads, and disk (3M Clean-N Stripe 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 a 3/S inch drill.

NOTICE: 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 Saturn P/N 21007432 (or equivalent).

NOTICE: The oil pump must be packed with petroleum jelly for priming if removed or the cylinder block is replaced.





2. Install oil pressure regulator and pump cover if removed.
Torque: 11 Nm (97 inch lbs.)
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 the oil pan, cylinder head to block, cylinder head and rocker cover T-joints to make sure gaps are filled.





c. Apply a 4.0 mm (0.080 inch) bead (refer to "RTV") on the front of the oil pan and a 2.0 mm (0.040 inch) bead on the front cover. Install cover immediately.

31. Prime fuel system.
a. Cycle ignition on for five seconds and then off for ten seconds.
b. Repeat step 31a twice.
c. Crank engine until it starts (maximum starter motor cranking time is 20 seconds)
d. If engine does not start, repeat steps 31a-c.
32. Start engine and check for leaks.
33. Fill the cooling system surge tank to the FULL COLD line and check for leaks after the engine has been road tested.

IMPORTANT: Allow the engine to idle for three to five minutes. If lifters are noisy or cylinders are mix-firing, warm the engine up at a low rpm (less than 2,000). After the coolant temperature has reached approximately 85�C (185�F), cycle engine rpm from idle to 3,000 for approximately 10 minutes or drive the vehicle five minutes to purge the air. If the air cannot be purged, the faulty lifters will have to be replaced.

34. Perform three mile road test and cycle engine under various loads.
35. Check for coolant and oil levels. Verify there are no leaks.
