Okay guys, last Tuesday I was coming home from NC, when I noticed my engine light started flashing. (I'm like well that's not good) So, I was on I-77 & looked up and noticed a Rest Area sign. So, I took that route to park it. Started bogging down pretty bad. So, I turned it off. Knowing that it won't turn back on. I checked the fluids and everything looked good. Nothing burnt. But it wouldn't start over. Then this random guy showed up with Snap On engine scanner. Showing my plugs were misfiring.

 

So, I get a rollback & take it to the shop. Well this morning, I checked on it. He said you want the good news or bad news first. I'm like ehhhhh, probably don't wanna know I stated. Well anyways, he pulled the driver side of my spark plugs and said they really bad. Where the electrode is, it's bent. So, he said something came off the engine and bent my plugs up. So, fml. I need an engine.

 

So, should I get a brand new one or an used one? Truck is' 07 1500 5.3L which had 172K on it. I plan on keeping it for another 3-5 years probably. Unless I get all my credit cards paid off, my personal loan, and 4wheeler payment. Then might be in the market for a brand new Chevy or GMC 6.2L truck. It's always something.

 

Options are I was gonna get a 6.0 to drop in it. I always said that if it ever went down. Should I get one or stick to the 5.3L? I have 4.56 gears and it's Black Bear tune. So, I dk what to do guys. Thanks!

I'd go with the 6.0 for one simple reason - no AFM. Unless, of course, you already had it disabled with your tune.

 

I have both - an '01 with the 5.3 and an '08 with the 6.0. The LY6 6.0 loves to rev, sounds awesome, and is a blast to drive. If it was me, the 6.0 is a no-brainer.

If you can find a good deal on a 6.0 I'd do it, but you have to remember that your trans might not hold up to it so well especially with over 170k on it

Yes I already had it disabled with my tune. Been like that for the last 50K miles.

 

I wanna go the 6.0 route, but what does it take to hook up properly to my truck? Does any 6.0 work or does it have to be the LY6 6.0?

I was thinking about that earlier. what's the difference in the transmissions in a 5.3 truck and a vortex max 6.0?

Some of the 6.0L engines have AFM. I know my 08 V-Max does.

Can someone help me with the swap? What all do I need? I know I need the Gen 4 IIRC. Since, I'm getting a 6.0. That's what I want. I finally moved out and got my own place and I'm starting to tow a little bit. I hardly ever did with my 5.3, except 1 time last month. Kinda amazing, since I had it since '09.

The LY6 will be cheaper and easier to find. Both engines use the L92 heads so you will need complete engines

Not sure. I went from iron to iron. I would imagine motor mounts may be the furthest you would have to go, but my guess is it will work

So, you have the LY6? What did my 5.3 have, iron? Where can I go to find everything out I need to know

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I find it amusing the OP doesn’t realize this threads heading includes several engines. He should have posted in the off topic section if he wanted a more narrow focus. I really appreciate and find amusing that he actually pointed out one of my many vehicles. The Odyssey. That happens to use 0-20 oil. I love pushing his buttons.

      Maybe, but it seems he is the only one that has backed up data to prove what he is stating. I think he is doing this more because he enjoys it and wants to get the information out to us. He's got the knowledge and access to the proper equipment and having the funds doesn't hurt.  I would love to do what he is doing and would do it if and when I hit the Powerball.  I'm not a Tribologist by any means but love to learn what I can.   I would bet there would be doubting people out there if a completely independent lab with high quality work and highly respected in the automotive industry, put out information like this.  The world can't be pleased, one just has to take the information that they are given, do more of their own research to find actual lab data to back up what they are trying to figure/find out.  Most don't bother, they just want to believe what they first see.     I don't have the minimax but my 6.2 in my 2019 Silverado with 64k miles shows excellent UOA results with 0w-20 and for my own purposes 5w-20.  Since not much of a change using 5w. I liked the data sheet information on the SS 5w-20 and figured I would give it a try.  Still the same viscosity at 100℃.   In the end we all just do what makes us happy, life is too short to get upset over trivial social media.   On a side note, I do feel GM has dropped the ball and just cares about the bottom dollar and not quality anymore.  "Like a Rock" has been long gone.  Seems "Built Ford Tough" has as well.

      2026 sierra bad brake controller

      By flattop · Posted

      Hello, my 3 month old Sierra Elevation wont recognize a trailer with electric brakes? All the lights work correctly, but no power to the brakes?   This is the factory installed brake controller. If you manually push the knob, the display shows the power % but does not light up like my 2022 silverado.   I have an appointment with the dealer, but was checking to see if anyone else has seen this issue.    Thanks,

      Post your latest oil change.

      By Black02Silverado · Posted

      Been using SS 0w-20 from new, but wanted to change to the 5w-20 because I liked the data on the data sheet, to me it seems like a little better product. But as you can see, not much difference. This is also with running a mix of 10 gallons E85 to a tank topped with 93. It isn't a flex fuel vehicle so any higher I get a CEL for running lean on both banks. Yes my mileage takes a hit. Instead of 20 mpg I normally get on trips I get 17mpg. This is also using EaO17 filter.  What is amazing is I have the AMSOIL cone filter on it since I have the GM Performance intake installed and that air filter has 44k miles on it.  I just take it out and shop vac it off once a year.  I use the upholstery tool on my shop vac.  Works well.
