garagerog replied to Foghorn17's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500Not the first time that GM has had problems with the DI high pressure fuel pumps. When GM went to DI on the 2.4 L 4 banger used in their Equinoxs and Terrains in 2010 it took them 2 to 3 years to get it ironed out. They ended up replacing pistons, rings, and camshaft chains in many of these engines on a special extended warranty. Gasoline washed the cylinder walls down causing premature wear and excessive oil burning. And of course GM initially denied anything was wrong and made the owners of these vehicles go through the inconvenience of the dealer oil consumption test, finally a light bulb went on at corporate and a revised fuel pump and extended warranty plan was instituted.
and another thing, with a V-8 running on one cylinder, sounds like a lot of unbalanced (meaning power strokes) rotating mass, I would hope for a forged crank with 4 bolt HD bearings. Might work out ok on an inline 6 on one of the middle cylinders, but on a V-8, I'll wait and see.
A few variables you need to fill us in on, I assume you're talking about a 5.3? Straight pipes on what kind of exhaust system, stock, or custom with headers, a true dual setup with a X or H pipe? Rather than loudness I would think you would want a system with the optimal amount of back pressure for all around performance and mileage. Unless you have changed the cam, you don't want to go with anything more than 2 & 1/2" on a true dual setup on a small block or 3" on a single exhaust system, 2" is to small with either setup.
Ok, with dynamic fuel management we can run on one cylinder, might as well put a hit and miss engine under the hood, or step it up a bit and go for the optional Johnny Popper, a two lunger torque monster! Before those that blindly except the latest technology start hating on me, this was said in jest.
garagerog replied to Sean3565's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500Love that color on your Sierra and I don't blame you for not wanting to get it dirty and salty, but hey you have a good excuse, that compact car parked behind your Sierra is blocking your garage exit and there's no way that compact could make it out of the driveway, right? lol . Looks like you have about 8" of wet snow? And btw the salt will hang around long after the snow is gone unless you get a gully washer so car washes that have the underbody wash are the ticket.
garagerog replied to badge171's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500There have been engine pre-oiling systems available for decades, I've never felt the need to install one, but sounds like the newer 5.3's with the new design oil pump might benefit from one.
garagerog replied to Goku760's topic in 2014 / 2015 / 2016 / 2017 / 2018 Chevrolet Silverado & GMC Sierra 1500Key words in this thread, "I went to the sand dunes", I'm sure that all the truck manufacturers build and warranty their trucks for normal 4x4 duty, snow and icy conditions, muddy back roads in the woods, etc. Extreme off-roading like dune climbing and rock crawling, not so much. Most of the extreme off-roaders build to the max an older out of warranty vehicle for such endeavors.
They do, there are organic based products using beet juice or corn syrup, but they work best as used as a pre-treatment, sprayed on the roads before a snow or ice event. I'm originally from e. washington state where they used the corn based pre-treatment and sand for the roads, no salt except for a little on the DOT sand piles to keep them from freezing up from residual moisture. The corn based stuff (my late Dad called it squirrel pee) will stain chrome wheels, running boards and such if you don't keep it washed off. I'm sure salt is much cheaper than the organic products, therefore it's wide spread use. Washington state probably uses it because they have the 2nd highest gas tax in the country, thanks to their ferry system, and snow removal in the cascade mountain passes.
Have been watching the Weather Channel's coverage of winter storm Grayson where they showed the city of Bostons preparation for the impending storm, 2 huge mountains of salt, 40,000 tons worth. I live in the low country of SC and it's 24 here now and we're getting snow now, only supposed to get 4 or 5 inches tho. And yes, they've been salting the bridges here, but being retired I have the luxury of staying home and not exposing my vehicles to the salt and crazy drivers. I feel for you that live in the NE, be safe out there, and if you have to drive your rig, get that car wash with the underbody spray as soon as practical.
garagerog replied to bigchevyz71's topic in 2000-2006 & 2007-2014 Chevrolet Silverado & GMC Sierra 2500HD/3500HDHow old are your batteries? When you replaced them previously were they both replaced at the same time? And finally did your dealer load test your current batteries or just come up with that after doing the diagnostic?
Welcome and I hope you find that 6.2 Sierra! But please hold onto that 89 K1500, you never know when you're going to need a granny gear (compound low) and besides that manual transfer case is a lot more reliable than the newer auto ones with all of the electronic actuation!
garagerog replied to 2016HD's topic in 2015 / 2016 / 2017 / 2018 Silverado HD & Sierra HD Issues, Troubleshooting, & Recalls/Service BulletinsOP, if your truck was parked outside in really cold weather it's possible if you had a pit in the windshield and you hit the defroster that's all it took to start the crack, more common than you would think. The reason that manufacturers don't warranty glass is that road hazards are beyond their control and people do really, really stupid things, like toss near boiling water on a frosted windshield because, well they're just lazy.
garagerog replied to aseibel's topic in 2014 / 2015 / 2016 / 2017 / 2018 Silverado & Sierra Accessories & ModificationsSorry Andy, I was being facetious about Wisconsin, in all likelihood the salt on your roads comes from Michigan which is a huge salt producing state including the Detroit area. Makings of a good conspiracy theory about Michigan, they get money from the salt they mine plus support the vehicle industry when they sell you a new vehicle every few years to replace your rusted out one.
garagerog replied to aseibel's topic in 2014 / 2015 / 2016 / 2017 / 2018 Silverado & Sierra Accessories & ModificationsYes, it would have been interesting to see what the upper control arm looked like but a couple of other things struck me, there is some type of fluid leak that has washed off the desiccated salt on the lower control arm, and speaking of salt, my gawd Andy, is half of Wisconsin's economy dedicated to salt mining? I live in SC now so no worries about that, but when I lived in the snow belt of eastern Washington state the DOT there used sand and in more recent years what my late Dad called squirrel pee, a corn based liquid sprayed on the roads prior to freezing much like the rust belt states use salt brine. Anyway Andy, I hope you are diligent about under body washes during the winter months.
