LS Engine Rebuild - 3 more ways to FAIL (and succeed?) - pt 2

- Опубликовано: 12 ноя 2022
- It's time for a budget LS engine rebuild! I'm refreshing the LQ9 LS 6.0 Gen III engine in my 2002 Cadillac Escalade, and as usual, this Flawless Plan isn't likely to go the way I intend...
In part 1, I did an engine rebuild and everything seemed to go along swimmingly, until it lost oil pressure about 100 miles in.
Today in part 2, I'll tear it down, see what happened, and try to push this rock uphill until my daily driver is running again. Or die trying.
Part 1: • How NOT to do a budget...

I REALLY appreciate you showing this....almost no RUclips videos show an issue while doing a swap...im so sorry this happened to you but I am glad you show people its great when it goes good but when its bad...its really bad
Thank you!
It's not a failure. It's content. Roadkill built a show around failures.
I have never watched an automotive video where I have shook my head more than I have this video,
You and me both, friend.
I seen this comment before I watched the video and thought you were exaggerating. You weren’t. I can build these in my sleep. He doesn’t need to prime it or any other BS. Turn the key and start it.
These guys that think they’re priming the oil system by cranking it over for oil pressure is idiotic. It does more harm than good.
I shook my head on part one when he let the bores go....😅😅😂
That amount of fiberyou found in the pickup tube had to have been from a piece of paper towel that was hiding somewhere. For that to have been just stray fibers , the inside of your engine would have looked like mold was growing on it.
I would wager ...Blue paper shop towel is what killed it. A piece ripped off and you didnt see it. It eventually choked flow off enough....and the result is what you experienced. My son will be watching this. Your documentation of this is outstanding reality. Thank you.
I just commented the same thing. That's too much gunk to be from stray fibers.
Much respect to you for showing your mistakes so others can learn from them. It takes a real Man to lay his struggles out RUclips for all see and critique. As someone who's engine builds never go right first try either.. it's reassuring to see im not alone. Awesome video. 🍻
I just cross threaded a spark plug too. First one in many many years. Fun fun
Like the way you owned it and stuck w the block. Embrace the suck…lol. I’m just getting into motors and rebuilds @ 53 years old. 04 suburban. Glad you aren’t gapping for boost, I didn’t understand why but assumed you were boost adding later. Glad the weather was ideal for engine pulling and installs. Works out that way just to make mistakes that much better.
Love the 4g63 crankwalk comment 😅
Reminds me of how everything goes when I work on things 😂🤦🏼♂️🤦🏼♂️ but same work through the challenges to achieve your goals!
Thanks for sharing. I have done a few engine rebuilds in the past. This is the extreme of what can go wrong. I have heard of things like this happening to some people even when they do everything right and it still goes bad. Thanks for showing all the findings of why, and how, when things didn’t work out. I myself any looking to rebuild my 2004 2500 Silverado and not buying new.
This was like watching a real live train wreck!😮
We do it nice, we do it twice lol. Sounds like me lol.
I'm stressed and it's not even happening to me. Just brutal. Can't believe those rags would leave that much even if they weren't lint free.
Let's just say I was surprised as well...
Dang, watching this gives me chills! The last year and a half I have had so many similar style mistakes and outcomes! I still don't know why this rebuilt LM7 bleeds off oil pressure when hot! driving me nuts! lol, thanks again for the videos, best of luck on future projects!
Man you can’t catch a break with this engine. Got the sticker last week thanks.
Thanks, Justin!
I read online that you can put the stretched gaskets in the freezer or refrig and they will shrink. It worked on my valve cover gaskets.
Just hit subscribe i watched the fist oart and now half-way through the 3rd build. I always take my block to Bob Lane in Gastonia NC to have them cleaned new cam bearing and plugs. They check the block hone and then i just use a mic and put it all together. The extra money is well worth it on a budget.
I did have the block cleaned by the machine shop after the hone on the (2nd? 3rd? attempt, but something persisted somewhere! Maybe the oil cooler, even though I flushed that by hand as well?
Engineering this is the bridge...damage report. Ahh blue water days?
New builds usually have sparkes….its just all the parts introducing themselves to eachother….just change the oil again in 500mi then again at 1000mi and the final at 1500 mi i would have ran 30w rotella diesel oil during those first 1500mi….
Another oil analysis is coming up soon!
Believe it or not it's those red shop towels. It's not a piece it's the Fuze it leaves behind. Same thing happend to me on a 454 rebuild. Micro fiber only now! My oil filter was full of red Fuze when I cut it open. It sucks.
no way that red rag left that much lint in the engine. Something much larger must have been in the pan. I would like to have a look at the oil filter.
Could be! I'll do an oil filter exam soon.
Those red rags leave tons of lint, I did a big block olds years ago, had to completely clean the block out after using them all over it. Was a mess.
You’re going to have some glitter on the first oil change. Make sure you change the cam retaining plate…. The seal gets hard and will kill your oil pressure. Changing the barbell isn’t a bad idea and modding the factory oil pump for more pressure will make a drastic change.
Turning the engine over to build oil pressure is wrong. So many things are turning to long with no lubricantion. It can’t build enough pressure because the engine isn’t spinning fast enough.
Just start it up. You’ll have oil pressure in 5 seconds. Lifter will be noisy for a minute until they pump up… they’re noisy to begin with.
I used to complain about getting a used 6.0 here in sf Bay Area but with the last month I picked up 2. The 1st one I got as a short block for $440. Turns out the crank was bad but everything else checks out. Then a few days ago I picked up a long block for $200. Again crank is bad but it has gen 4 rods and pistons. Had to get a little more aggressive and it worked out
Where are you getting the engines from? I am in the same area. Looking to get a block.
I'm gathering parts and preparing to rebuild the LMG in my Yukon. You sir are my worst nightmare. Did you not use a Haynes LS book?
I think the fibers were gasket scrapings. Do you plug off holes when cleaning surfaces? Do you run a vacuum near razor blade edge as your scraping?
There is no way there was that much lint from just cleaning the cylinders. Plus, most of the left over lint would probably be burnt or blown out the exhaust. Unfortunately, somehow, something did get stuck. Maybe you plugged the pickup tubes to keep junk out and didn't remove it?
I feel your pain. I've had a few engine boo boos myself and they are never fun.
P.S. Don't trust plasti-guage. It's close but usually off enough to make me not use it. I "C" mic the crank journal and then dial bore gauge the bearings after torquing the down.
man your projects go like mine
I know its a year late but your initial failure of the clogged pickup looked to me like a cheap oil filter falling apart, that paper cellulous material appeared to be from a crap filter.
I think the fibers were from stop leak used by previous owner.
Is there no break in? I know roller lifters should be forgiving. Im pulling my gen 4 5.3 now and I'm pinched up pretty tight as it's my first rebuild.
Wow brother. That sucked but you are right. $ 500 is alot better then 14 or $1500 plus prob more machine work. I'm working towards my first swap. I am going to swap a 6.0 into my 03' Crown Vic. I now know why you can't use red shop towels. I kept saying to myself every time someone sId don't use them. I ordered lintless kwipe cloths.
Good decision!
Did you polish your crank before the rebuild?
my father's engine run full of sand, idk what you did wrong but it look like old shreded gasket piece or loose gunk from inside somewhat came out after being loosen up, but for some reason kept hidden until you ran it then clogged the pickup tube. im pretty sure your towel dust did not destroyed your engine. its sad that you saw your oil pressure was off too late because your gauge work fine,
i want an update on how this held up?
I've only gotten about 1600 miles on it since, but it's still running OK, still has oil pressure, and I just did an oil change and sent the sample off for analysis. Fingers crossed that it's breaking in OK!
Dang man how muçh for a stock dart block from summit bro, guesh.
Did you change all of your oil seals and O-rings?
Hey I have a question are you interested in selling your stock LQ9 pistons I am rebuilding a LQ4 the flat tops would raise my compression a little.
Can for the love of god good sir masking tape all of those ports, spark plug holes, oil cap, etc please. I don’t want too have too see you do this again. Especially because I saw a little human in the background and that could be so bad. I wish you all the best!
I’m refreshing a 5.3 and you are making me worried
So how did it go brother? It's been 4.months now.
...And I've barely put 1600 miles on it in those months. But it's still going! I just sent another oil sample off for analysis, so I'll do an update when I get the results back.
Oof... 73rd times the charm, or not. That was like 6 seconds of no oil pressure. They make a tool that goes into the hole past the threads, then expands and clears the threads on the way out so you dont send chips into the cylinder. This video and the previous one was a total train wreck.
Probably should have had it decked too
That motor is posses 😂
What happened to pt 3?☹️
Coming this Friday morning!
That is not the correct quote. Abraham Lincoln actually said "Don't believe everything you read on the internet."
Or pay a shop to ensemble it for u
I think you might be better off at having someone build the the block for you then installing it it’s no shame saying this is not my thing and you get a warranty 😮
😂😂😂😂😂
Just buy a low mile used motor next time.....😢😂 i found that motor forn3 grand with 55k miles and 5 year warranty
My wife would’ve killed me…..
Your hat is on backward
That explains it! Flipping it the correct direction would probably fix my issues.
Wouldn’t it be smarter to get the engine tested before you install it? Asking for a friend…😅
I definitely ground start them when possible.
All good stuff respect 🫡 at least you learn something about ls engines and everything looks good this time around that engine should be bulletproof when your done now hopefully 🤞
