I get that to, also 14,xxx miles on the truck. Almost sounds like a real quite diesel noise. (at least i think thats what that noise is) Hopefully it's normal cause my truck still runs like a top!!

I've never experienced lifter noise but I've always ran full synthectics after the first 500-900 miles. :uhoh:

 

I don't believe you should be worried. Check your oil level and put your mind to rest.

I havent noticed anything with my truck, it was in the 20's when I went out this morning. My old 2000 (5.3) had a noticable "tick" at startup. Had it in and was told it was nromal early on, gm even gave me a 100K warranty. Never had an issue with it.

 

Quick question do you park outside? My old truck was parked outside for the 1st 5 yrs I had it. My new truck is always garaged and it is 45+ in there.

My 2011 6.2 does it to on startup but it stops after about 2 minutes, just a light tapping sound. I figure it just takes a little for the oil to get to the lifter valleys on a cold startup. Only does it when its very cold out and vehicle hasnt been started in awile.

And here I thought I was the only one.....

Heard the lifter noise about a week ago during cold start up and was freakin out, truck only has 11,000kms and I'm running mobil1 synthetic.

I always let the motor run for a few mins. before pulling away and never hammer the throttle till the motor is up to operating temp.

Mine does it when cold, pretty confident its the old short skirt pistons knocking, just like every other gm V8 made in the last 10 years. Nothing to worry about. :uhoh:

I park in the garage, but it is unheated, so it is only a few degrees warmer then outside. So it warms up pretty quickly and the noise goes away once warm.

I don't have a 6.2L engine but I do have an iron block and I've heard ticking only on the coldest morning here in CA. And that was only for a few seconds. If it doesn't use oil I wouldn't worry.

Alright folks, with this generation of engines in the GMT-800s and 900s, you WILL hear CSK and lifter noise, it's just an unfortunate thing about how they designed them. Does not matter if you run synthetic or regular dyno. Does not matter if it is brand new or if it has 500,000 miles. Many trucks will do it, some will not. Don't loose any sleep over it and just drive the dang thing. And no, it does not matter that you may have paid $40,000+ on your truck, the engine is still going to do it.

I have noticed a little cold start knock on the cold mornings this winter. Sounds a bit like a diesel for 30-60 seconds. I've got 6000 km on my truck.

If its iron then you have a 6.0 not 6.2 Sir

      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...
