FaultCrate・GMC Yukon 2000–2006・Warning light, Check engine / Service Engine Soon
Candidate cause (the documents say what to do)
Single-cylinder misfire (P0300-P0308) and/or chirp, squeak or tick at camshaft speed: worn cam lobe / lifter, valve or valve spring
Customers may complain of an SES light, engine misfire and/or engine noise.
A verified noise is not eliminated by canceling fuel injectors and occurs at camshaft speed (half of crankshaft speed).
How to tell
P0300P0301P0302P0303P0304Check engine / Service Engine Soon
What to do
- 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.
- The misfiring/ticking cylinder should have less cam lobe lift than comparison cylinders if a worn lifter roller and/or cam lobe is the cause.
- During the noise, press with a wooden hammer handle on the rocker arms at the valve side, push rod side, and side of the rocker to find which one is making noise.
- Measure the cam lobe lift at the push rod side of the rocker arm.
- A good indicator of a sticking valve is engine misfires that continue to count on an aggressive deceleration with engine braking.
- Release the air pressure from the cylinder and work the valve up and down in the guide while turning it 360 degrees; if any binding is felt, a stem to guide clearance concern exists.
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.
What is needed
- Parts and materials
- Camshaft and all lifters (if a worn camshaft lobe or lifter roller is found)
- Plastic lifter guide (for the lifter that had the damaged cam lobe or lifter roller)
- Valve spring (if found broken)
- Labor time

A cause or a result a complaint states is the owner’s view or what a dealer told them, not an established fact.
Put together by FaultCrate from public records and technical documents. The cause and the repair are for the workshop to decide with the vehicle in front of it. Counts are records, not failure rates.
