Engine Timing - Verification

2004 Chrysler PT Cruiser Touring, 2.4 B, AutomaticSECTION Engine Timing - Verification
WARNING: This page is about a different car, the 2004 Dodge Intrepid, 2004 Chrysler Intrepid, and 2004 Chrysler Concorde. However, it is still accessible from the selected car via links, so may be relevant.

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. (Refer to REMOVALΒ ).
  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 90Β° from the cylinder head cover sealing surface (Fig 1) on both right and left cylinder banks.
  4. Count chain pins from the mark on the intake camshaft towards the exhaust camshaft. Engine is timed correctly when there are 12 chain pins between the timing marks on the intake camshaft and exhaust camshaft (Fig 1).
  5. If marks are not correctly aligned, proceed to Timing Chain and Sprockets for service procedures. (Refer to REMOVALΒ ).
