Yeah, right.  I'm sure the dealer kept my AV under 55 for all of the 100+ miles it took to pick it up from another dealer and deliver it to my house.  On Monday morning, I saw two AVs with dealer plates headed east together on I-96, probably being swapped between dealers.  Both were doing 80+.

 

I would say drive it reasonably and change oil frequently.

The speed thing is silly.  Go as fast as you want.  But I wouldn't do anything full throttle.  For the big block, I'd say never get over 3,500 rpm. And never have the rpm at one constant speed for more than a couple minutes.  I'd say you only need 2-3 hundred miles doing that and you're fine.  And no heavy braking in that period either.  Just like if you had just got a brake job.

Well, do you want the technical or the realistic way?  :D

 

I do it by the manual, I have friends (and foes) who don't give a sh*t and put it to the boards pulling out of the dealer lot.  :D

 

All I know, was when I tore my engine down to be built two years ago, the machine shop was shocked as to how perfectly wore everything was.  I attribute part of this to properly breaking it in as well as constant preventative maintenance.

I would say a hard break-in will take miles off in the long run. If you plan on keeping it for the long haul, be nice to it and you'll save repair bills down the road and get a loy more miles out of it. If its a lease or you plan on selling it in the next 2 years, treat it like a rent a car and you probably won't notice any difference (but the next owner might, eventually)

I think the resale value would be higher on a private sale if you convince the prospective buyer how diligent you were on maintenance and break-in. If it gets traded in at a dealership in the next few years with 30 or 40K miles on it, they won't care about break in or maintenance, since they are going to mark it up to the same price on their resale regardless of those things.

Just my 2 cents..

I own nothing but manual shift vehicles, When I get something new, I punch it to the floor and redline the engine for the first 10 starts (if possible). Then i drive it normal.

 

  I'll never forget the day back in may of 1991 when I picked up a brand new V-Max. i pulled out onto the boulevard outside the dealer and punched it to redline through the first 3 gears. 2 weeks later I brought it in for the 600 mile valve adjustment and the owner of the dealership met me in the parking lot screaming profanities at me about how he would not do any warranty on the bike.

  i still own it now and it has one of the best running engines I ever owned.

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
