[QUOTE="REDFIREKNIGHT, post: 5442849, member: 62561"] Here is the procedure for the "Tick" concern, I hope this will help you. ACTION: Use the diagnostic procedures listed in this article to evaluate the vehicle condition and replace the cylinder head if applicable. Refer to the following Service Procedure for details. SERVICE PROCEDURE NOTE: THIS REPLACEMENT CYLINDER HEAD WILL NOT IMPROVE OR REDUCE PERFORMANCE. In order to diagnose noise, the following items must be checked. Verify noise by placing a stethoscope on the back of the left head near the exhaust ports. Verify that the noise is heard in the left side exhaust system (left side wheel well or catalytic converter, from underneath the vehicle). Try to isolate the noise by canceling the cylinders, by unplugging the injectors one at a time (start with #8 cylinder). Verify that there are no exhaust manifold leaks. Check to make sure that the camshaft spacers are in place. If not, install cam spacers and retest vehicle. Check for proper cam sprocket bolt torque, retorque to spec Check for spongy lash adjusters Verify that the timing chain tensioner pin has been removed. If the above diagnostics does not eliminate the noise while the cylinders are cancelled, and the engine was built prior to 11/1/2002, replace the left side cylinder head and cam assembly. Good luck every one. Lets just hope its an exhaust leack and not nothing major. [/QUOTE]
