2011 Silverado LT 1500 5.3L - 115k i know of the low oil pressure warning issues with these trucks. I have owned mine since 60k miles and faithfully change my oil every 5k. i have AFM delete done. anyway - i had about 200 miles left before my next oil change, and we left for one last camping weekend. it's only a 2-hour trip at 65mph. I checked all fluids, all was great. had to pull over every 30 minutes or so because I'd get the low warning and id have to shut off the truck. i waited a few minutes and it fired right back up and oil pressure was at 40 PSI then steadily dropped over 30 minutes of driving until the lights came back on. this scenario happened 3x on way up. Saturday morning i went and had an oil change and now things are back to normal. ran at 38-42 PSI pulling my trailer (26' alpha wolf) with no issues. what exactly causes that? did my oil mysteriously lose all viscosity? should i have my sending unit and screen replaced? i heard of the oil tube o-ring issues as well. not sure how to verify if that's the issue or not. ahyway - i think from now on i'll be changing at every 4k

yeah - i saw that - i will try that as well

so, i have yet to investigate this. sorry for the delay. i just have been taking my chances with the windows rolling up or down. I am ready to explore this. I have a question first, might seem dumb, but if I cut the rubber conduit what happens if: I find the wires are fine? How do I reseal the conduit once cut?

he could have at least said what he had to say in some form of intelligible language

got it - thanks - mine are not directional.

thanks - i had it backwords.

what's the proper tire rotation for a 2011 Silverado 1500 LT? fronts go straight back, backs crisscross to the front? searched google and got a million different answers

Solved. #4 spark plug boot was slipped off. Whew. Easy fix. Purring like a kitten now thanks

ahhhh - i see. thanks. i'll report back with my results. thanks again

i hope its an easy fix. I have had a cylinder #7 misfire (3 years ago) and that plug was oil fouled. i replaced all the plugs and never had an issue since. i also at that point disabled the AFM. When i had the original misfire, i never had the stabilitrak message. what makes that message appear with a mis-fire?

2011 Silverado 1500 LT 4x4 - 114K miles 5.3L - AFM disabled took a 5 hour trip north pulling 26' travel trailer and all was fine. 2 week vacation with normal drive, all fine. Left for home yesterday and 1/2 way thru the trip home stopped to get gas, about an hour later stopped at rest area and when deceling the truck sounds like it was exhaust braking (BOP BOP BOP BOP). Stopped truck - used rest room, came back and truck fired right up but had a rough idle and a rough acceleration. once about 25mph or so, truck ran fine. no power loss and no change in gas mileage/performance. experienced this rough idle behavior the last hour trip home. after parking trailer, i checked for codes - and none, none stored and none pending. no lights either. truck still drove the same after dropping off trailer. this morning, fired right up - and 30 seconds later, flashing CEL and Service Stabilitrak. left truck at home and drove wifes car. i plan on checking for a loose spark plug wire when i get home. any other thoughts on what to look for? I didnt have time to check codes before work this morning so i will when i get home. with in the last year i have all new plugs, wires and coil paks. can you all give me some other ideas before I take it to my mechanic?

clean well - use the por-15 system (cleaner, prep, product) and you are good to go

in for an answer. i have a 2011 Silverado 5.3 and mine does the same thing.

just to show how my truck behaves here are 4 pics from my commute home from work. its only a 15 mile commute at 60mph for 10 of the miles Pic 1 first pic i am at operating temp - 60 mph - 1500 rpms oil pressure 42psi pic 2 - further down the road - oil at 40 psi pic 3 - in city - 40 mph and oil at 38psi pic 4 in town at stop light - 22 psi

yes - mine varies at times - but usually hovers at 30psi

i had the exact same issue. 2011 Silverado, 5.3l - 110k. i was at the upper limits of my mileage and ready for an oil change. on start up id be at 42psi, as i drove it would hover at 22psi - not normal for my truck. i had the oil changed and viola - back to normal. sometimes the springs (valves) in the oil filter and go out, causing low oil pressure. i believe this was my problem and possibly yours.

thanks for the insight. i will investigate and report back. it may be a few days - but I will report my findings

Good afternoon. I am experiencing weird issues with my rear power windows on both drive and passenger side. both rear windows will roll down, but not up with their own window switch in the back doors. i can (intermittently) roll them up with the master switch on driver door. the other day, i couldn't roll the passenger rear up at all. i ended up opening and closing the rear door, then i could roll the window up. any ideas on what i should start looking for? Appreciate any help. thank you 2011 Silverado 1500 4X4, 5.3L 100k miles

I looked it up - "New New Body Style" - learn something new every day

I have a 2011 5.3 - driver side front bolt is broke - all on its own. the amazon kit I believe is for the back bolts only. i refuse to pay over $600 to get my bolt fixed.

well - i was quoted $650 to replace all the bolts. and if one breaks on them, take on another $65 per bolt that breaks. then they told me that they would have to remove the head - and who knows what that will cost. has to be a way to do this without head removal.

as i suspected. i'll make some phone calls and also have a price on replacing all the bolts to ARP thats a good suggestion. thanks

did you get a police report?

2011 Silverado, 5.3L 1500 LT. I noticed that the driver side FRONT exhaust bolt is broken off. I can only stick a probe in the hole about 1/4". I assume the head sheared off below the flange. i know this is a common issue, but 99% of the time its the rear bolt. Is there an easy fix? they sell a bracket for the rear bolt breakage, but is there anything for the front? or do I need to bite the bullet and pay a shop to get it out? appreciate any input. thanks

i guess i may not need one. but how accurate are the gauges clusters? just wanted it for looks i guess thanks for the tips
