NOTE: Note: The engine timing verification procedure is the same for both conventional roller-type (early production) or silent type (late production) secondary timing chains.

Correct timing is critical for the NON free-wheeling designed, 2.7L engine. Engine timing can be verified by using the following procedures:

  1. Remove cylinder head covers. See Engine/Cylinder Head/COVER(S), Cylinder Head - Removal  for left side. See Engine/Cylinder Head/COVER(S), Cylinder Head - Removal  for right side.
  2. Rotate engine until number one cylinder is at TDC on the EXHAUST stroke.
  3. View the intake camshaft sprocket timing mark. The mark should be 90° from the cylinder head cover sealing surface on both right and left cylinder banks.
  4. Count the chain pins between the timing marks (2) on the intake camshaft and the exhaust camshaft. Engine is timed correctly when there are 12 chain pins between the timing marks (2) on the intake camshaft and exhaust camshaft.
  5. If marks are not correctly aligned, proceed to Timing Chain and Sprockets for service procedures. See Engine/Valve Timing/CHAIN and SPROCKETS, Timing - Removal .
