Hey guys I’m new on this forum. I’ve never owned a GMC or a truck before and this is a first for me so it’s definitely a learning experience for sure so any help would be much appreciated. It’s a 2014 GMC Sierra 5.3. I recently had the AC condenser line break on it causing it to leak transmission oil everywhere in the bottom half of the engine bay. Got it taken care of. When I received it from the dealer it was still covered in oil residue. I was pretty mad about that but I cleaned it up pretty well with engine degreaser. Then I checked back a couple of days later and there was oil still after I had cleaned it so I took it back to the dealer and they pressure washed it (or so they told me) and now it’s all gone. Anyhow afterwords now everytime I start the truck up and it starts getting warmed up quite a bit of white smoke comes out of the exhaust. It’s pretty common for cars and trucks to do this I know but the smoke smells like burning oil. The truck isn’t leaking oil or coolant on the floor. After I drive and warm up it goes away. But once I park the truck anywhere and start it up again it smokes, I drive a little and it keeps smoking then stops. If I’m stuck in traffic idiling it smokes as well. Any help would be useful please. Could it be a serious problem or still left over old oil residue or just me being paranoid?
im new to the site, im nick i drive a 2002 silverado 4.8L 2wd step side mileage 240k dont tell me to sell or junk my truck the truck has been kept up with pretty well. In the mornings or after the tuck has been sitting a while i will get a pretty noticable ticking for about 30 seconds at startup until the engine warms up, i also get kind of a cough up of white smoke out the pipe at the same time, both of these symptoms go away after about 30 seconds. the truck will drive normal and strong until the first time i have to gas it into traffic or an incline/boat ramp, pretty much anytime i get into the gas pretty hard i get the loud ticking and smoke with a big sluggesh power loss at the same time. things to note- about once every 2 weeks i get a low oil light, i check the stick and its bone dry...heres where it gets funky, if i add only about a quart and a half the stick reads alost an entire half inch PAST full on the stick, so from bone dry to over full with a quart and a half????? No, there is no oil stains on my driveway no coolant in my oil or vice versa it is the oem factory dip stick i did a compression check, all the chambers on the drivers side are even at 140 in all cylinders, all chambers in passenger side are at 170 exept one was 180, im not worried about the pressure changes from that 10psi on the passenger side of the motor but what i do find strange is how one entire side is lower by about 30psi than the other head, warped head? head gasket? the plugs did look a little white corrosive and a few inparticular had a bit of carbon build up on them i took my valve covers off and inspected the lifters checked all the oil passages that i could see from there, no sludge or anything to note, brand new valve cover gaskets, no visible leaks from the exterior of the engine were could all this oil be going, it doesnt seem to be enough smoke in the orning or while im hitting the gas hard to be burning that much oil? could a cracked or bad valve seat be the culpret? im starting to get frustrated and how the heck can it go from empty to full with 1 1/2 quart??? ive tried this while hot and cooled down, always on level ground... im sure whatever is going on with the oil loss is the culprit for the ticking and smoke, I just cant seem to figure it out any help would be appreciated
