Chevrolet Silverado 1500: hello, i own a 2010 silverado 5.3

Customer Question

hello, i own a 2010 silverado 5.3 1500 4x4. its consuming oil at a rapid rate. id ballpark 2q every 4-5k miles. im used to checking the oil so just the consumption isnt my main concern. the truck has 26000 miles now and its oil fouled 2 spark plugs so far and misfired setting off the DTC light. PCV fixes maybe?

Are you under warranty?

yes its under warranty.
Expert:  Neal replied 2 years ago.
You need to get it to the dealer and get this documented, depending on how bad the oil usage is you might be getting a new engine. There have been issues with oil usage in some of those.
Customer: replied 2 years ago.
could you please opt out? i beleive i need to consult with a GM tech that works at a chevy dealer. reason being, he would be privy as to what they are really doing to fix this issue. i beleive it to be in the AFM system or PCV. my local dealer said they replaced that first plug because it cracked. thanks for your time and effort though.

Have you talked to your local dealer about this yet? There are a few concerns on these trucks about oil usage. There is a bulletin for the number 1 and 7 spark plugs getting oil fouled.

hi mike, i took it to the dealer the first time for the #1 plug fouling. although they didnt say it oil fouled, they said it cracked. i raised concern for that, and the advisor said " weve seen a few". it of course remedied the misfire so i took the truck. i was on the road after hours on the weekend when #7 misfired. i had to purchase an iridium plug at autozone to get me through the weekend. i saved the plug. it has oil residue built up on it. what should i ask for when i return? its only a matter of time before the issue resurfaces im sure.
Expert:  Michael Moore replied 2 years ago.

Here is some information on a bulletin they need to look at. This information is avaible to any dealership and the last time you were there they should have performed this repair which is to replace the valve covers.

 

#12-06-01-001: Service Engine Soon Light On, Rough Running Engine, Cracked or Oil Fouled #1 and/or 7 Spark Plug - (Jan 18, 2012)

 

 

Some customers may comment on a service engine soon light being on and/or rough running engine. Technicians may find DTC P0300 set. Upon further investigation, technicians may find cylinder #1 and #7 spark plugs oil fouled and/or the porcelain may be cracked or broken on the combustion chamber side.

 

 

This occurs on the driver's side (left side) of the engine due to PCV pullover that adds additional oil to the cylinders that can foul out or damage the spark plugs.

 

 

Install a new left valve cover with the revised baffle to prevent PCV pullover that adds additional oil to the cylinders.
