Rocker Arms and Lost Motion Assemblies
Inspection (D16Y5, Dt6Y8 enginesl
NOTEr When reassembling the primary rocker arm,carefully apply air pressure to the oil passage of therocker arm.
1. Inspect the rocker arm piston. push it manually.- lf it does not move smoothly, replace the rockerarm assembty.

6, Remove the camshaft holders. then measure the
widest ponion of the plastigage on each journal.
Camshaft-to-Holder Oil Clearance:
Standard lNew):0.050 - 0.08!t mm
{0.002 - 0.004 in}
Service Limit : 0.15 mm {0.006 in)
lf the camshaft-to-holder oil clearance is out ot tol-
erance:- And the camshaft has already been replaced,
you must replace the cylinder head.
- lf the camshaft has not been replaced, first check
the total runout with the camshaft supported on
V-blocks.
Camshaft Total Runout:

Rotate camshattwhile measuring.
L
- lf the total runout of the camshaft is within toler-
ance, replace the cylinder head.
- lf the total runout is out of tolerance, replace the
camshaft and recheck the camshaft-to-holder oil
clearance. lf the oil clearance is still out of toler-
ance. replace the cylinder head.

Glearance
1.To check main bearing-to-journal oil clearance.
remove the main caps and bearing halves.
Clean each main journal and bearing half with a
clean shop towel.
Place one strip of plastigage across each main jour-
na l.
NOTE: lf the engine is still in the car when you bolt
the main cap down to check clearance, the weight
of the crankshaft and flvwheel will flaften the plasti-
gage further than just the torque on the cap bolt.
and give you an incorrect reading. For an accurate
reading, support the crank with a jack under the
counterweights and check only one bearing at a
time,
Reinstall the bearings and caps, then torque the
bolts.

lf the plastigage measures too wide or too narrow,
(remove the engine if it's still in the car), remove the
crankshaft, and remove the upper half of the bear-
ing. Install a new. complete bearing with the same
color code {select the color as shown on the next
page), and rechsck the clearance.
CAUTION: Do nol fil€, shim, or scrape the bearings
or tho cap3 to adiust cleatanc€.
lf the plastigage shows the clearance is still incor-
rect, try the next larger or smaller bearing (the color
listed above or below that one), and check again
NOTE: lf the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.
