53.
Prevent debris from entering the block, front cover, oil pan, and oil and coolant passages by taping, plugging, or sealing the passages prior to
removing old gasket material. Immediately put shop towels in the front of the oil pan once the front cover is removed and plug the two oil passages
in the block. See Figure 18. The passages can be plugged with plastic plugs such as power steering hose plugs or tape. These same two passages
must be plugged in the front cover before attempting to remove the old gasket. If debris does enter these passages, it will cause engine damage.
The area around these passages should be hand scraped to avoid any possibility of contamination. It is important to prevent contamination from
occurring. Debris cannot be cleaned out without engine and front cover disassembly.
NOTE:
Leave rags and plugs in place when cleaning gasket particles off the front of the block. Remember to carefully remove the plugs and rags from the
passages and oil pan before installing the new gasket. Use care when removing so that contamination does not enter the engine.
54.
Remove the camshaft position (CMP) sensor drive gear.
55.
Reinstall the crankshaft damper bolt.
56.
Rotate the crankshaft until the timing marks and the keyways are aligned. See Figure 19. This will position cylinder number 1 at TDC of the
compression stroke, which is also required for camshaft synchronizer assembly installation.
