Sierra 1500 8-cyl

  • 55,554 miles


I own a 2007 GMC Sierra 1500 crew cab. I have some issues when I start my truck in the mornings, I get a tapping noise as if there are lifters stuck or not getting sufficient oil. I have always used the recommended ac oil filters that I purchase from the local dealership parts center so I know that the filter is not the problem. I am a mechanic so I know what an engine is supposed to sound like. The noise will continue until the engine warms up which is approximately 10-15 minutes and is very annoying. I am currently deployed to kandahar, afghanistan in support of operation enduring freedom and schedule to return to the us in late March 2012. I spoke to my wife today and she said that every time she start the vehicle for the first time the noise is there. I would appreciate if you could answer my question concerning this issue. I like the truck but the engine noise has to go. Like I said before I have been a mechanic for over 30 years on construction equipment and automotive equipment for the us army. Please do not try to give me a short answer to try to get rid of me, I know better. The crankcase is full of oil to the correct level on the dipstick and I use the recommended 5W30 oil. Why am I having this issue? note: I am deployed so please don't try to contact me by phone.

Sierra 1500

  • 50,000 miles
The contact owns a 2007 GMC Sierra. The contact stated that the vehicle was losing oil. The dealer wanted the contact to allow them to check the oil every 1000 to 3000 miles to diagnose the vehicles oil consumption. The manufacturer then told the contact that all GM vehicles use excessive amounts of oil. The contact was concerned about the excessive oil use and why he was not advised when the vehicle was purchased. The manufacturer sent the contact a letter stating that the vehicle was designed to use 1 quart of oil every 2000 miles. The failure mileage was 50000 and the current mileage was 70000.
