    2011 Silverado
  1. check your oil level? when was last oil and filter change?
  2. AFM Delete and extended warranty

    Appreciate your input and comments. food for thought. thanks
  3. I have a 2011 Silverado LT with 74k on the dial. bought it 6 months ago. I do not experience oil consumption between changes. Been reading about the AFM delete. I have an extended warranty that covers all lubricated engine components for another 20k miles. with said warranty, should I worry about the AFM delete chip or leave well enough alone until warranty get close to expiring?
  4. 2011 Silverado - P0454 Code

    awesome - thanks for all the help. the code hasn't come back, but if it does - i know what to do. thank you
  5. wife got home from work last night and informed me CEL was on. read the codes and I had P0454 evaporative emission control system pressure sensor intermittent. possible causes: Faulty fuel cap Improperly installed fuel cap. Faulty purge control solenoid. Clogged charcoal canister Broken charcoal canister Broken or cracked vacuum Broken or cracked fuel vapor hoses Faulty pressure or flow sensor. A bad powertrain control module is a possible cause, but it is very rare I removed fuel cap, cleaned off seal and tighten - that's about all i can do. she drove it today (30 miles) and no issues if it comes back, is my only option a dealership? is this a common code for silverados? 2011 Silverado - 70k on the dial after thought - it was -20 degrees here for a few days. yesterday was 45+ degrees - a 60 degree change over night. I wonder if a seal somewhere on the evap system shrunk due to the cold and just took time to get back into shape?
  6. is there a way to tell by looking at the outside of the engine if your truck has the updated valve cover? 2011 Silverado 5.3 L crew cab 76k miles
  7. sorry if it offended you - surely wasn't my intent good luck
  8. I cant speak for everyone else.......but.......wow - punctuation is needed to make that easier to read
  9. p0521 - simple question i think

    its been over a week since oil change and so far so good. I suspect I can remedy this in the future by making sure i check oil level weekly, and keep current with oil changes. i was 500 miles over the sticker on the windshield, not that that matters.
  10. p0521 - simple question i think

    thanks for that additional information. the oil is changed and I reset the CEL. So far so good - have about 1.5 hours of drive time. Oil pressure per the gauge is close to 40 at 1200 rpms, and 30-ish at idle. I need to double check what filter they used. its AC-delco i'm sure. i'll look at the receipt later. i'll keep everyone posted. thanks again
  11. p0521 - simple question i think

    I'll have to invest in one. something I need to add to the tool box - lol thanks i'll keep you all posted.
  12. p0521 - simple question i think

    THANKS - I know of the sensor and the screen. the question was "what to trust?" the CEL (not the oil light) or trust the gauge
  13. So, we purchased a 2011 Silverado 1500 LT with 62k on the dial in August. I am ready for my first oil change based on the windshield sticker (actually 500 miles over) the engine light came on last Friday while wife was driving. checked the codes and it was the p0521. i checked the oil and i was a quart low. I added a quart of 5w-30, and reset the check engine light. it came on again last night. I reset the light. I drove the truck this morning at highway speeds (60mph) and the oil pressure was steady (35-38 psi) at highway speeds. Once i got into town and stopped at traffic lights it would drop to 22-25 psi and the needle would bounce a few PSI. I am getting the oil changed today at the dealership. if the p0521 come back after oil change, is it really that big of a deal? seeing how per my pressure gauge my pressures are fine?
