Cylinder Head Specification for
1980-86 Chrysler (AMC Renault) 1.4L (85 CID) Engines


The following cylinder head specifications are for the Chrysler
1.4L (85 CID) C2J and C3J engines. Both engines are used in the
AMC Renault Alliance, Encore and Renault LeCar. Be sure to
verify the engine model number before surfacing the cylinder
head.

Type Cyl. Head Thickness

C2J Engines 2.866 +/-.002 new
2.846 +/-.002 minimumafter surfacing

C3J Engines 2.850 +/-.002 new
2.830 +/-.002 minimumafter surfacing


Cylinder head height (thickness) is measured from the deck
surface of the cylinder head to the rocker cover rail (A). The
cylinder head must be surfaced when distortion is in excess of
.002.

The two engines can be distinguished at the identification plate
attached to the cylinder block above the oil filter. If the top
line contains the number seven (7) immediately to the left of the
slash (/), then it is a C3J engine. All others are the C2J
engine. AERA members have found most vehicles equipped with the
C2J engine.
