Are you mechanically inclined? You obviously can harm the engine any more by taking it apart and looking at the internals. It's relatively easy to remove the heads. You could tear apart the top end and have the heads checked/machined. The LS motor is super easy to work and doesn't require much for tools. How many miles on the motor? You could rent a compression tester and do the tests yourself. Burning oil usually means valve guide seals or piston rings, a compression test will narrow down the problem to a specific cylinder. I find it hard to believe that they can't find an engine, hell, I'm sure you could bolt in a 5.3 truck motor if you really wanted to. (Don't quote me on that). Im also curious to see what the "catastrophic" damage is. Probably AFM related?

 

 

Don't know your budget, the
19420382
Brand new LS3 long block is the deal of the century at 4,999
I am linking this thread to a freind who will have an L77 available in the future.
Depending where you are maybe he could make a deal.
Not a scam, I have been here a while and the guy with the engine possibly for sale is well known.

Where or how was the vehicle stored for the past three years? To better guesstimate the value of the car, current mileage? Condition? Accident history? Color? Etc.

The vehicle was stored in a garage for the majority of the time. the past year it has been at the dealership waiting on a used engine. No accidents. 163,000 odometer. Maroon.

 

Hi everyone. This is my first posting.

My car is in need of an engine. It developed a knocking sound. The first mechanic diagnosed it as “catastrophic” but he no longer rebuilt motors. I was referred to someone who, in retrospect, really didn’t know how to rebuild the motor. Now, the engine burns every drop of oil and blows white smoke out of the exhaust pipe. No mechanic wants to tear down the motor given they don’t know what was/wasn’t done to it. The dealership has not been able to locate a used motor to replace the original motor. The car has not been driven since May, 2018.

I’m considering purchasing a new motor. Given the amount of time is has not been driven, what other problems may have developed from non-use?

Does anyone have an idea of the value of this car, which is in good shape, without an engine?

Any advice would be appreciated. Thanks.

Where are you located or where is your dealer located? Several ways to help from here in N. Georgia, as far as used engines.

I’m not mechanically inclined. I don‘t know the first thing about engines. The dealership said they did a leak down and crank tests. I’m going there tomorrow to speak to the mechanic at the dealership. The motor has 163,000 miles. What is AFM related? I think the first mechanic thought it was a lifter problem. About a year prior to the knock, the radiator hose blew off and the engine got hot, but not quite to the danger zone. i had the radiator, pump, serpentine belt and hoses replaced. The dealership said they‘ve looked for the same motor but have not found one.

 

The comment by the mechanic about the lifter, he was referring to the active fuel management/ displacement on demand (AFM/DOD). The lifters are prone to failure and can cause catastrophic damage to the engine. Let's see what the mechanic says.

 

Given an AFM issue may require a new cam, I'd be hesitant to spend a lot fixing a motor with that many miles. May be time to consider a full rebuild or replace. Price your options.

 

Probably end up pretty close in price after factoring in all machine shop work plus labor. Glad I learned how to do it myself.

 

Would be nice to find a non-dod 6.0 or 6.2 that isn't $6,000 used. L99 or L98 maybe? Then swap over the intake stuff. That should run on the stock ECU (with the DOD tuned out). Maybe the superchips tuner can do this simple thing?

Or go with a low miler L77 from a Caprice and take your chances with the DOD again. But I think they upgraded the DOD lifters on those? I've seen them for like $3000-$4000 used. Sell your old motor to reduce costs.

Maroon as in sport red metallic. If the car is in otherwise good condition, it could be worth at least $6,000. The demand on displacement/ active fuel management lifters are prone to failure. They're removed and replaced while performing a dod delete. Can forum search dod delete for additional information.

 

Easiest option is to put a crate LS3 in and move on or sell it if you aren't inclined to invest.

I have seen a few modded engine blown/less G8 GT shells go for $3-7500 [full bolt on, tons of work]

 

just for comparison on value,im in your area Gonzales LA, bought a 2009 white no sunroof, one owner car that sat out in the weather for four years,car runs but needed/needs a lot of maintenance and tlc from sitting out,no wrecks,178,000 miles no whiskey dents,i paid 4,300.00 for it.probably overpaid a little but i took it on to save it.

 

The L77 is also a great alternative. It is a complete motor, so no hours swapping parts and gaskets. Only thing you have to swap is your silver blade throttle body. New water pump new alternator new power steering pump. Better fuel injectors. It also has the new style lifters so no death tick later on. Make you totally reliable in one shot. At $5727.00 it’s drop it in. Fill with oil and coolant and drive away.

if this is what you get for that money that is not bad at all.

 

Not positive but that picture,might be misleading .
Found same part, number,as a long block too.

Your photo, maybe too good to be true ?

If it really had all the accessorys, front drive ,etc that would be unbeatable.
All the front stuff I bought for my LS7 was a couple grand by itself

 

Look at your photo! Those are cathedral heads and a iron block. If you look at GM sites, 19256262 is listed as a Engine Complete Assembly. Not just a long block. A call to the seller would confirm it. This one appears to be assemble line replacement/ warranty engine.

 

Just typed and lost a novel.

Drew, not saying you are wrong.
Was showing there is conflicting info out there.
Yes a call would clarify
If that is an accurate photo, that is an incredible price.
Maybe a blow out ?

 

5700 for a long block does seem high to be fair.

 

I'm having trouble finding specs on that motor. I see some sites say its AFM. Can't find it in the Chevy catalog. Is it new?

Summit shows it dressed:

My point , you cant nessasarily trust the pictures

If true, dressed L99 for less

Personally I think they are "file photos"
Happy to be wrong though ,,, and admit it,,, as it means there are some fantastic deals to be had.

 

Over three months ago, this was asked on Summit Racking and hasn't received a response, "Does this motor come "fully dressed" with all accessories that are pictured"? As mentioned, best to call and inquire.

 

Good deals. But both still have AFM lifters. I’d still think I’d go with the LS3 long block.

Good Morning,
See attached for what is included with the engine.
Thanks!

Edit:
Anyone see that fully dressed engine photo on an actual GM sight along with that part number?
Anyone else have a reply in writing from a seller of that part number stating the engine fully dressed with accessories?

 

Contacted Summit Racing via chat. Below is the unedited transcript.

Me:
Hello,
Does the 19256262 engine setup come fully dressed? As pictured with the alternator, power steering, pump, air conditioner compressor, and other accessories already installed?
Summit: After looking on the vendors site it looks like this item has been discontinued and will not be available anymore. I will have to have our site updated
Me: Part number NAL-19256262
Me: Okay. How about NAL-12631106 ?
Summit: They are showing this also Discontinued
Me: Very interesting. Will both listings before removed from the website? Thanks
Summit: I am having both removed from our site
Me: Sound great. Have a great day.

 

And now from my dealer

My dealer photos show them as what they are .
One an assembly, one a long block

Neither are or were complete dressed like the beauty photos.

 

figured that was to good to be true.

 

The L77 complete looks better as a quick drop in for a bad motor. No tune needed. Better lifters, better injectors. You now have an extra intake and heads for porting or sale.
