Well I got the truck back today and they claimed nothing was wrong just an extra half a quart of oil no gas smell.... The two techs that diagnosed and originally took it in ran away and didn't come out till I was leaving, they changed the oil and said bring it back in a thousand miles and they will look it over again. The lady tried to tell me gas and oil also smell the same..... they brushed me off like nothing. Awesome to see how amazing GM customer service is.
I hope it is for all of you, if so I have no clue what is going on with mine and I am quite upset since a three month old truck with a sticker north of 56k and not even 8500 miles. I would be concerned with all the trucks and the vast mileage range this is popping up at, it could be some bring it back in ever 10-50 thousand miles for the same issue and just wait till it happens again out of warranty. $$$$$$$$
You should notice it drop from when your driving then come to a stop and are sitting there then when you drive it will increase to around 40 and if you go over 3500 rpm it will kick into high pressure mode and run anywhere from 60-80+.
It's a service bulletin for a collapsed valve in the afm cylinder that leads to the tick. This link should take you there.

I took it in for an oil over fill and the heated seats wont come on with remote start, pulled it into the bay and they pulled the dipstick and instantly smelt gas. I was given an unlimited mile loaner and nothing else was said just I would get a call later.
No codes the only thing is my oil pressure gauge started running 5 lbs lower at operating temp. After driving this loaner they gave me my truck was way down on power.
Yes slight is normal, mine smelt like you were standing over an open gas can and I have a feeling the condensation was gas that was splashing on the back of the cap. The tech smelt the gas as soon as he pulled my dip stick didn't even have to put it by his nose it was that strong.
Has been really good for my driving 3 mpg over my r@m didn't really notice a change around this time just slight fluctuation like i normally get. Completely disappointed wish I had my last silverado back. Thank gosh my dealer is amazing!!!
Just based on the reading off the dipstick there had to have been 1-3 quarts of gas in the oil, the truck has had all service done by this dealer and nothing else. I've only had it three months and am extremely regretting not getting the 2500 diesel, needless to say this truck will be going back for a new one.
