Went to the dealer today to address my oil cooler connector leak...On the 17 mile trip there I glanced at my rear view and notice white smoke coming out the back of my truck.  I though WTH, it stopped almost immediately as I saw it.  Thinking I went over a something on the road.  While at the dealer I didn't think anything of it.  I just wanted my oil leak addressed.

 

On the way back it did the exact same thing!!!  I may have been doing more but I didn't notice.  Definitely not consistant.  Good it be my head gasket?

 

Look at the oil filler cap, looked fine...Same with dipstick and coolant overflow.  Looked fine too.  Just ordered the chemical test from Amazon to check it for myself.  What the heck is up with these trucks.  Less than 1000 miles and less than a month old.

 

Went out this evening and started it up and idled for a while...no smoke just water vapor.  No bubbling in the coolant bottle either.

 

Anyone else aware of this issue?  Am I paranoid?

I'm afraid its today's GM. The former Giant just isn't too good anymore. Mary Barra's cost cutting at its finest.

Going to do the chemical block test this weekend and document with pics.   

 

If it tests positive then I'm starting the process of dumping this truck.  I've spent a the last month visiting the dealer each week.  This is the icing on the cake right here.  Not a minor flaw

That woman is going to kill this company, what she did with the Blazer was a travesty and now the bread and butter truck is just a mess that wont stop having issues left and right.  I would like to know on how many they bought back at this point.

Just think when all 4 corners has an electric motor driving these things and the computer and battery systems it will require. I don't have high hopes moving forward with the cheapest part available over quality mentality GM has without question taken under Bara's tenor. Not sure i'm willing to trade softer dash with stitching over durability and parts that are not made to fail causing catastrophic failure. These lines use to only leak, now they just completely blow out at the crimp and dump the engine in the process.

      Some Assembly is Required

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Gas Prices

      By Grumpy Bear · Posted

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?

      Future GMC Jimmy

      What are your thoughts? The Chevy Blazer relaunch was an epic case of 'lunchbag letdown'. Jeep Wranglers and Ford Broncos stick out like a sore thumb.    The AI photos do not look like a 'retro version', but shrunken Tahoes. Get away from the 'futuristic look'. I've seen two concepts. One had rectangular headlight like a Rivian and the other way to big should include dual round headlights like the early version.   If not this would look OK   At least it has GM styling (albeit the K2XX) A lot of the images floating around look like Bronco IIs or the current Bronco. Looking at the Broncos in my area (central Ontario, it seems to be a mix of 2 doors and 4 doors, 'mall rated' to ones that could go offroad.    I'm sure a AT4 and AT4X RPOs could be outfitted similar to a Rubicon if the braintrust understood the whole offroad scene. Crosing my fingers that if it does see the light that the front air dam/bumper doesn't extend below the center line of the tire...

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      And overpriced. I was in the Oshawa Truck Plant when they were being built. Very few. I could count on one hand how many I've seen since
