The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:Gauge or instrument faultWarning lightAir conditioning or heaterLights (headlights, turn signals)NoiseLoss of engine power, no accelerationSmoke or fireLeak

Record by record

13 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

Work done

How it is said to have ended

  • says it was fixed1
  • says it held for a while1
  • says it came back2
  • says it did not fix it6
  • result not stated3

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

Known issuesSingle-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring2

  1. Manufacturer communication2000–2006 GMC YUKON DENALI ・ 2017-08-15

    Engine Misfire and Service Engine Soon Lamp Information

    1. 1Fault

      • With the SES light on, a P0300-P0308 DTC is found with misfires counting on a single cylinder, which may or may not be felt.
      • The noise may be described as a chirp, squeak, squeal or tick and may increase off of idle.

    2. 2Finding the cause

      Possible causes

      • A worn cam lobe on this engine family generally makes a consistent chirp, squeak, squeal or tick at camshaft speed and/or a misfire with a P0300-P0308 DTC.

      Steps to confirm (in the document’s order)

      1. Press on the rocker arms with a wooden hammer handle while the noise is present; if pressing the valve side of a rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.
      2. Measure cam lobe lift at the push rod side of the rocker arm; it will differ from the SI specification but should be similar to the other rockers on the same bank.
      3. A bore scope or pen light may help when inspecting the cam lobes through the lifter bores.
      4. A good sign of a sticking valve is that misfires keep counting during an aggressive deceleration with engine braking.
      5. The Cylinder Leakage Test in SI should typically isolate valve leakage by showing excessive leakage past an intake or exhaust valve compared with the others.
      1 more points

    3. 3Correction

      Repair

      1. If a worn cam lobe or lifter roller is found, replace the camshaft and all lifters per SI, plus the plastic lifter guide for the affected lifter (for the 2010 model year, all the plastic lifter guides).
      2. If force is needed to tap the valve off its seat, there is excessive carbon build up, which may be repaired by decarboning the engine.

    From the manufacturer’s document

    • Applies to：Applies to 1999-2013 GMC Savana, Sierra and Yukon (with a V8 engine per the model list) (note: the Yukon years run later than the years this service covers).
    • Condition：With the SES light on, a P0300-P0308 DTC is found with misfires counting on a single cylinder, which may or may not be felt.
    • Condition：The noise may be described as a chirp, squeak, squeal or tick and may increase off of idle.
    • Cause：A worn cam lobe on this engine family generally makes a consistent chirp, squeak, squeal or tick at camshaft speed and/or a misfire with a P0300-P0308 DTC.
    • Confirm：Press on the rocker arms with a wooden hammer handle while the noise is present; if pressing the valve side of a rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.

    • Repair：If force is needed to tap the valve off its seat, there is excessive carbon build up, which may be repaired by decarboning the engine.
    • Confirm：The Cylinder Leakage Test in SI should typically isolate valve leakage by showing excessive leakage past an intake or exhaust valve compared with the others.
    • Confirm：The two pieces of a broken valve spring can stay stacked together and be hard to see, so lightly push on different places on the springs with a small hammer handle.

    Remedy
    This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on, engine misfire, and/or engine noise. Technician may find Diagnostic Trouble Codes P0300-P0308. If published Service Information diagnostics does not isolate the cause of this concern technician should check for a worn camshaft lobe and/or lifter roller, a sticking valve, valve leakage, a broken valve spring, and a collapsed active fuel management lifter.

      This Preliminary Information communication provides information to the technician about vehicles that have a Service Engine Soon Malfunction Indicator Lamp on, engine misfire, and/or engine noise.

If published Service Information diagnostics does not isolate the cause of this concern technician should check for a worn camshaft lobe and/or lifter roller, a sticking valve, valve leakage, a broken valve spring, and a collapsed active fuel management lifter.

      What the documents say to do

      Single-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring

      Confirm

      • If pressing on the valve side of the rocker changes the noise, a lifter and/or cam lobe concern on that cylinder is most likely.

      Repair

      1. If a worn camshaft lobe or lifter roller is found, follow SI procedures to replace the camshaft and all lifters.
      2. Also replace the plastic lifter guide for the lifter that had the damaged cam lobe and/or lifter roller.

      Caution

      • A damaged cam lobe is easy to overlook when inspecting through the lifter bores; unworn lifter rollers do not mean the cam lobes are okay.

    Normal vehicle movement in Park after cold start

    1. 1Fault

      • At start up after a cold soak, the vehicle may rock or move slightly forward or rearward while in Park, sometimes with a clunk noise.

    2. 2Finding the cause

      Possible causes

      • Residual transmission fluid in the clutch packs creates a partial apply on start up.
      • The movement stops when the parking pawl holds and/or the fluid exhausts completely from the clutch packs.

      Steps to confirm (in the document’s order)

      • Verify by comparing with another identically built vehicle under the same cold conditions.

    3. 3Correction

      Repair

      • To prevent the movement, apply the parking brake whenever the vehicle is parked, as the Owner's Manual recommends.

      Caution

      • The condition is normal and no repairs should be attempted.
      • The slight movement has no adverse effect on the transmission.
