Scoupe L4-1468cc 1.5L SOHC VIN J MFI (1994)
With the addition of the auto lash adjusters, the valve clearance has been changed from a manual adjustment type to an automatic adjusting type.
The roller rocker arm and auto lash adjuster reduce friction between the contacting parts.
NOTE:
When the engine is first started, a tapping noise may be heard. The noise is caused by air flowing into the auto lash adjuster through the oil passage
and should disappear after a few minutes.
When checking or replacing the auto lash adjuster, please refer to the Bleeding and Leak Down Tests.
Bleeding the Auto Lash Adjuster
1.
Insert an air bleed wire into the hole of the auto lash adjuster and move the plunger up and down 4 or 5 times.
2.
Remove the air bleed wire and push the plunger strongly with your finger. If the plunger moves even slightly, repeat step 1.
3.
If the plunger still moves after repeating steps 1 and 2, replace the auto lash adjuster.
CAUTION
^
Since the auto lash adjuster is a precision part, care should be taken so that foreign objects and dirt do not enter the auto lash adjuster.
^
Do not attempt to disassemble.
^
Use clean diesel fuel for cleaning.
^
When fully bled, hold in an up-right position to make sure the diesel fuel does not spill.
