This teardown gave your shop floor that good old Dexcool clean and polish. Great to learn about the minor differences on the LS engines between the generations and vehicles GM drop them in over your videos.
Looks like the Piston was trying to do with the twist and shout By the way I've learned so much by your videos I thank you, you are very educational on tear Downs also I just want to say I wish you a great life and great wishes for your shop to do the best it has ever been every year have a great one happy early Thanksgiving and have a Merry Christmas
Makes me nostalgic to hear that low key St. Louis sense of humor again. Another fun teardown to watch and some interesting info about the engine. I'd love to be able to buy a random piece of small scrap off you that's signed with a paint pen or something and stick it up on my wall.
I used to have an olds intrigue with that trans and the 'shortstar' motor. Definitely not the power of the 5.3 but more than enough for healthy burnouts and a dead trans in less than 50k.
Thank you for all that you do, great tear downs. I'm no mechanic. But I'm pretty sure I can sum up almost all of the failures...people are dumb and don't do the basics: check oil levels, change oil on a regular basis.
Thanks for the vid Eric. Been a tough day and I’ve been looking forward for the video. Awesome stuff as always. Appreciate you making the bad days a little less worse.
I loved the inside of the oil pump...i never really considered that they'd have to be positive displacement pumps - it's obvious now that I know, but I'd just never thought about it. Thanks for that and please keep it up! I always learn something from your vids!
I showed this to my wife because I have been looking for one to make a cup holder for my truck. "You're in your 50's. What do you need with a second bent rod?" That's what she said.
I have an 86 Fiero I bought new. Has the v6 engine, manual transmission. 284.000 miles on it now, and the engine has never been touched. Still runs perfectly fine. Its the SE model, with the special front end, and big whale tail spoiler on the trunk. And of course its...RED.
found this video searching for valve cover replacement on my ls4 in my 06 impala SS, Really neat seeing a complete tear down of an engine like the one ive been trying to keep on the road for years especially now having oil pressure issues... Thanks ERIC!
May consider getting a pan that can sit on the engine stand legs that's low profile, or in a way that makes your life a little easier with fluids. Might save you a lot of time in clean up.
After reading a few of the comments I became convinced that the rod was bent as a result of hydrolock, just thought I'd mention that in case you missed it...seriously, I enjoy your teardown videos and seeing the innards of some of these mechanical nightmares. Being an older man and "old school" at heart, the LS 5.3 is the cleanest, "keep it simple, stupid", design I've seen yet.
Yeah,.... 2005 6.0 here, dropped my oil pan to replace the oil O ring, and found two shiny pieces of foil like metal and a quarter inch beaten up glob of aluminum, no sludge. Oil pressure still slowly bounces up and down slowly but oil pressure is up at 40 driving down the road.. Was going to put a Cam in it, now I'm waiting to do a fresh build, doing lots of research... thanks for the Videos..
I had one of these in my Monte Carlo SS. Burned oil pretty bad and had to fight with the dealership to get it considered to be a problem, then had to wait for the oil pan gasket fix, which I think just added a baffle. Still burned oil, maybe slightly less. By the time I got rid of it, it had developed piston slap at just over 100k.
I've encountered oil consumption with LS engine's myself. The biggest problem is not using the recommended oil. It should be DEXOS 5w30 or whatever it calls for in the owners manual. DEXOS is a certification of a synthetic oil. Use anything else it will consume oil faster. Doesn't mean not to check the oil at least 3 times a year. In my opinion.
So there I was. Saturday night, and my son and I had our dipping sauces ready to enjoy with our Piston McNuggets. Disappointed, but still entertained. Keep them coming.
Thanks for the teardown! I may need to do this someday because I currently drive a '08 GXP. Everything is original on the engine internals but I try to change the oil regularly and don't do burnouts. It doesn't burn oil since I disabled DOD. The crankshaft is 13mm shorter than a regular LS in order to fit sideways.
We rebuild them (along with every other LS engine) built a few last week that fit the Impala SS and have an LS3 for a G8 that will go together Monday if I get my .020 over rod bearings in.
You can save yourself a lot of mess if you have a dedicated shop vac and vacuum out the cooling system before disassembly. Works great! The higher airflow shop vac the better.
I too have an E34 540i/6, also a M62B44 & Getrag 420g in a hot rod project. I work at a machine shop tearing down, machining, rebuilding engines. Even though I'm around engines all day, I greatly enjoy watching your videos. Keep em coming!
A few things that were missed is that the ls4 uses a unique crank that’s very similar to a ls6 style that is shorter than a standard 5.3 crank it also requires shorter bolts from the flex plate to crank shaft. different bell-housing and mounting locations to accommodate the 4t65e-HD few other little details but All around a great tear down video.
I have a 2007 LS4 and it runs perfect. I’m the 2nd owner n it has 158k miles now. It has 118k when I bought it. Replaced transmission at 140k miles n she’s been running great ever since. I do use Full Synthetic oil and 93 octane gas. Got up to 156 mph on interstate

Very interesting . I have a 94 Trans Am I bought new. It has the 350 LT1 engine. The engine has never been touched, aside from spark plug replacement every 100.000 miles. even the timing chain is original. 338.000 miles on it now, still runs and sounds like new. It uses no oil between 3000 mile oil changes which have been done since new. Castrol GTX. It doesn't smoke,, it has always passed the California emissions test. Lifelong Southern California car, it still looks great inside and out. And occasionally I'll give her the beans and she's still quite fast 😊
Thanks!! And thats from an old guy!! Built many Pontiac engines , Last one was the one in my 70 Judge, Have an 06 Grand Prix GXP as a driver and love driving her.. So very cool to see your teardown of this engine. As for the bent rod!! Very cool artifact.. would of loved to be in the cylinder wall to see that one happen..
I always try to figure out the failure mode as the video progresses, but I missed on this one a bit. With the engine turning (relatively easily) but water sitting on the valves, my first thought was that the valve train wasn't turning (stripped timing gear). But, then I could see the lifters move when you cranked it over with the head off. So, not that. The "low" piston looked like classic hydrolock... only question is if it was water ingestion (unlikely with only one bent rod) or a blown head gasket from the apparently undertorqued head. Unless the hydrolocking stretched the head bolts, but that rod isn't bent enough to be a full-cylinder waterlog. So I would REALLY check that head out, because it may very well be warped, not from extreme heat, but from being undertorqued. The bearing carnage though... so little sign of oil starvation up top, so much below. This has the looks of a high-mile bottom end that was a bit abused, then had a head job done (and timing chain) only to have been assembled poorly with a loose head and the resulting bent rod. Then they still tried to run it until it was condemned. I don't know factory LS head gaskets but those looked aftermarket. Or, another theory is that they popped a head gasket and hydrolocked it (bending the rod), had water in the oil and still tried to run it (hence bearing damage). Did a head gasket change to try and solve the problem but with the bent rod it never ran right, and was condemned.
I have an 07 ss and I feel the same, besides an oil leak coming from the valley plate gasket, the car has been pretty good to me and runs like a champ and is such a comfortable ride.
Really interesting that even on the most simple engines we’re always seeing or learning something new about them I’d really like to build one for my 96 Chevy blazer 4x4 since you can’t get that many performance parts for the 4.3
You can though they are essentially a 350 missing two cylinders so there's a lot of parts for them just not much when it comes to intakes but I do know if you have a carb 4.3 you can hack up a 350 carb intake and it will fit just have to plug the intake runners you don't use can't remember if it's front two or rear been awhile since I messed with one
Man after watching you do a teardown, I will never try to fix my LS engine if something should happen to it. Yes, it is a Silverado and an 05. It does run well due to synthetic oil and filter and every 3000 miles. Thanks for your video as it was very informative as to what it takes to do a teardown never mind a rebuilding. You must be a GM mechanic. I enjoyed your presentation- Thanks.
The pig mats I used in the fuel business rejected water specifically. You could literally separate water from diesel with those mats. Blue ones. The white mats absorbed all liquids.
Run the engine out of oil and seize the rod bearing. The crank keeps spinning, the bearing stops bearing-ing, the rod starts to spin along with the crank, and now you have a banana rod. Or a two piece rod with half of it now bashing a hole in the block.
I have a 2006 Impala SS with 166K miles. Mine's not beat, I'm the original owner, I drive it like an adult and 80% highway. The car is not suitable for street racing, it is a 4-door sedan with good passing power. It has never done a burnout. That's how I drive it and I keep the engine oil changed regularly. The engine does consume some oil compared to my 2002 Avalanche iron block 5.3, but not terribly bad. The transmission is still working well, I changed the factory fill and filter 6 years ago and everything looked clean in the pan. The engine is getting tired, has a little piston slap and lifter noise when cold. Still runs OK and the DOD has never malfunctioned. It does eat water pumps, it's on its 3rd one right now. I will restore the car soon and I have ordered a replacement crate engine from GM. They currently have a good PN for the replacement engine but had none in stock. My dealer parts guy (super parts guy) called GM's rebuild center and was told they had 1 core on hand and if they get an order for it they will fill it, but if no order comes soon then GM will probably discontinue the PN. So I put in the order for the crate engine. Lead time is 60 days, I told them to take their time. I don't have any use for a bent connecting rod, and it's a good thing because I'm not gonna be able to come up with any teen tier sex jokes to get a thousand likes anyway, lol.
Thank you so very much for doing a tear down of the LS4 fwd engine I requested you to do.!! I asked, and you replayed this video! Thanks again! regards! Denis
Those VLOMs aren’t that bad to replace. I just recently replaced the one in my ‘06 Impala SS that has just under 150k on it. Labor booked like 2.5 hours but I was able to get it done along with plugs, wires, trans service and an oil change all in that amount of time.
I bought a 2006 Impala SS brand new. I absolutely loved that car. Almost got it a turbo on it. It would have put out around 500hp, but I really didn't have the money for repairs if something broke. Damn I miss that car!
I've had a 2006 LS4 w/auto trans 4t 65E in an 88' Fiero GT since 06' , it's fabulous fun to drive👍 the FWD with shortened crank made it fit w/o toooooo many problems...lol..
"That's a lot of fluid." I am shocked you haven't fitted some kind of drain pan support at the bottom of your engine block with how often these things leak all over your floors.
Or just a shop vac to empty the engines. It's faster to suck it out a port than off the floor. Replacement pans from x-large dog crates are perfect for the stand, wider than those pre-formed types & cheaper.
0:20 it was GM's attempt to stay in the minds of enthusiasts while they got the Zeta platform ready. Problem was, by the time the W-car V8s were ready, the LX cars were already a thing.
@@mikefoehr235 If the engine didn't didn't have plugs in it and the guy took it through a car wash or it sat in the rain or whatever it could have got in there.
I have found on these engines it’s the damn low tension piston rings that creates the oil burning issue. I turned my wife’s DOD off at 48k miles and it still burnt a quart every 2k miles. The EPA has put more of these engines in the junk yard than anything else. Better living through regulation.
It's just a bad design of the 2nd pressure relief valve, it plugs #7's oil control ring by spraying a LOT of oil into the cylinder. You have to un-stick those rings and get the updated pan even if you disable DOD.
Dear sir, you are a scholar and a gentlemen. I enjoy watching your videos as they are a fun watch and to drink my tea with as i explain engines to my gf, who sometimes watches them with me. I love the carnage of the blown stuff and your humor as you explain. I'm an EJ man myself but very much realize they're short comings. A good day to you from Canada, eh
Thanks for the video. I own a 08 super with 74000 miles. This is the first teardown I have seen on the motor. No problem with my Buick yet but....... .
Love your videos. The information you give as you show the parts and procedures all the way through is many times surprising. While I’ll never tear down an engine it’s all very interesting. I also like that you don’t pull punches on engine designs. I while never buy a car with DOD. Dumbest design mandated by our wonderful EPA.(morons) Ah well can’t wait for the next video.
These engines are junk..I had one in a 08 Impala SS. tick tick tick tick tick tick tick...went through 3 of them. Tick tick tick tick tick. It would scoot though, even with the automatic
Looks like a hydrolocked cylinder... I did that to a '92 Toyota Hilux while on a typically long Australian road trip. I did get it started and apart from slight vibration, the ol Toyota got me home and to work for a week before a rebuild was decided on. A front wheel drive V8? You yanks must have strong wrists. Can those second gear burnouts be done it a straight line?
These videos are a good resource to learn about what could possibly go wrong internally when you don't take care of an engine, if nothing else... This one may not be a case of poor maintenance per se, but it clearly saw some condition it shouldn't have. It's interesting to me, in technical terms, how the smallest bend in a component such as a con-rod can cause so much to go wrong. Some very interesting content in all these videos. Keep up the good work 🙂
I had a 2007 Monte Carlo SS with that engine and it was alot faster than people would give it credit for. Not the fastest thing on the road but alot of fun. Especially when people thought the last gen mcss was slow, open that thing up and it would walk away from alot of cars that was surprising.
I like how You every time spilling the coolant and oil directly to garage floor and not having any oil pan laying down the engine. Pretty much my style.
Anyone that has one of these that is burning oil and smoking out the exhausts (valve guides)! Try some AT-205 from ATP! It worked magic on mine. A few ounces with every oil change will cause it to burn no oil whatsoever. GM should have included a case of this stuff with every car! This might have saved this engine.

By the way I've learned so much by your videos I thank you, you are very educational on tear Downs also I just want to say I wish you a great life and great wishes for your shop to do the best it has ever been every year have a great one happy early Thanksgiving and have a Merry Christmas
Makes me nostalgic to hear that low key St. Louis sense of humor again. Another fun teardown to watch and some interesting info about the engine.
I'd love to be able to buy a random piece of small scrap off you that's signed with a paint pen or something and stick it up on my wall.
I would as well.
I would buy the hell out of some piston mcnuggets. :-)
Great video. Learned a lot while watching. No "baby talk" or swearing. Thank you
It doesn’t matter how old it is , every disassembly is a good learning experience great job
If you want a car that will do nothing but burnouts, even when you don't want them to, you need a Impala, GDP, or a La Cross with one of these 5.3s.
Only problem is when you do those burnouts you destroy the differential and take out the whole transmission with it
I used to have an olds intrigue with that trans and the 'shortstar' motor. Definitely not the power of the 5.3 but more than enough for healthy burnouts and a dead trans in less than 50k.
Who loves FWD burnouts
@@windanthonystream my GXP will do better burnouts than my C6 vette
in a snow storm!!
Thank you for all that you do, great tear downs. I'm no mechanic. But I'm pretty sure I can sum up almost all of the failures...people are dumb and don't do the basics: check oil levels, change oil on a regular basis.
And leave old gaskets on
Thanks for the vid Eric. Been a tough day and I’ve been looking forward for the video. Awesome stuff as always. Appreciate you making the bad days a little less worse.
I love the idea of giving the parts away. I know I won't get it but I love the idea. Keep up the hard work.
I loved the inside of the oil pump...i never really considered that they'd have to be positive displacement pumps - it's obvious now that I know, but I'd just never thought about it.
Thanks for that and please keep it up! I always learn something from your vids!
I showed this to my wife because I have been looking for one to make a cup holder for my truck. "You're in your 50's. What do you need with a second bent rod?" That's what she said.
I have wanted to put one of these 5.3L LS4's in a Pontiac Fiero.
I have an 86 Fiero I bought new. Has the v6 engine, manual transmission. 284.000 miles on it now, and the engine has never been touched. Still runs perfectly fine. Its the SE model, with the special front end, and big whale tail spoiler on the trunk. And of course its...RED.
I don't think I've ever seen a water pump that big before. That's massive!
found this video searching for valve cover replacement on my ls4 in my 06 impala SS, Really neat seeing a complete tear down of an engine like the one ive been trying to keep on the road for years especially now having oil pressure issues... Thanks ERIC!
There are over 75 hit songs with the word Saturday in them but none as sweet as the sound of an impact wrench ….quickened
Coffee, roll, and a pretzel rod video make an excellent start to the day! Great stuff.
May consider getting a pan that can sit on the engine stand legs that's low profile, or in a way that makes your life a little easier with fluids. Might save you a lot of time in clean up.
That was really awesome. I have never seen a complete tear down like that. Especially with somebody that can spot damage. Leaned tons! Thank you!
wow , an overhead valve engine ? I thought I heard that bearing yell " freedom ! " when it shot right outta there 🤣 . Cool video 👍
After reading a few of the comments I became convinced that the rod was bent as a result of hydrolock, just thought I'd mention that in case you missed it...seriously, I enjoy your teardown videos and seeing the innards of some of these mechanical nightmares. Being an older man and "old school" at heart, the LS 5.3 is the cleanest, "keep it simple, stupid", design I've seen yet.
16:49 yes great to see inside the oil pump, see the carnage if metal gets in there.
Yeah,.... 2005 6.0 here, dropped my oil pan to replace the oil O ring, and found two shiny pieces of foil like metal and a quarter inch beaten up glob of aluminum, no sludge. Oil pressure still slowly bounces up and down slowly but oil pressure is up at 40 driving down the road.. Was going to put a Cam in it, now I'm waiting to do a fresh build, doing lots of research... thanks for the Videos..
I had one of these in my Monte Carlo SS. Burned oil pretty bad and had to fight with the dealership to get it considered to be a problem, then had to wait for the oil pan gasket fix, which I think just added a baffle. Still burned oil, maybe slightly less. By the time I got rid of it, it had developed piston slap at just over 100k.
I've encountered oil consumption with LS engine's myself. The biggest problem is not using the recommended oil. It should be DEXOS 5w30 or whatever it calls for in the owners manual. DEXOS is a certification of a synthetic oil. Use anything else it will consume oil faster. Doesn't mean not to check the oil at least 3 times a year. In my opinion.
@@HotRod8625 Mins always got mobile 1.
DoD life.
@@HotRod8625 Dude come on its the shitty DOD. A dexos oil or not doesn’t make THAT much of a difference thats marketing BS
Mine has 180 k on it and it's running fine.
So there I was. Saturday night, and my son and I had our dipping sauces ready to enjoy with our Piston McNuggets. Disappointed, but still entertained. Keep them coming.
Excellent video buddy. Love the tear downs. You know your way around an engine. Big Al.
Thanks for the teardown! I may need to do this someday because I currently drive a '08 GXP. Everything is original on the engine internals but I try to change the oil regularly and don't do burnouts. It doesn't burn oil since I disabled DOD. The crankshaft is 13mm shorter than a regular LS in order to fit sideways.
Twisted rod would be a great name for a garage band!
We rebuild them (along with every other LS engine) built a few last week that fit the Impala SS and have an LS3 for a G8 that will go together Monday if I get my .020 over rod bearings in.
You can save yourself a lot of mess if you have a dedicated shop vac and vacuum out the cooling system before disassembly. Works great! The higher airflow shop vac the better.
That's what I do, just pull the t-stat and rotate it on the stand. I hate getting coolant on the ground since it never evaporates.
I too have an E34 540i/6, also a M62B44 & Getrag 420g in a hot rod project. I work at a machine shop tearing down, machining, rebuilding engines.
Even though I'm around engines all day, I greatly enjoy watching your videos. Keep em coming!
You need to nickname that engine 'Annie' cause, with that bent rod, you know its had a hard knock life.
I love the time and attention to detail you put in to get us those bolt cracking sounds, is like a “chef’s kiss” every time I hear a set !
A few things that were missed is that the ls4 uses a unique crank that’s very similar to a ls6 style that is shorter than a standard 5.3 crank it also requires shorter bolts from the flex plate to crank shaft. different bell-housing and mounting locations to accommodate the 4t65e-HD few other little details but All around a great tear down video.
I have a 2007 LS4 and it runs perfect. I’m the 2nd owner n it has 158k miles now. It has 118k when I bought it. Replaced transmission at 140k miles n she’s been running great ever since. I do use Full Synthetic oil and 93 octane gas. Got up to 156 mph on interstate
This was a teardown and a half with that twist for sure! As always, thank you for the great content!
Knowing you make calls and spend real actual money on decisions made by majority consensus of your comments sections earns you mad respect from everyone. Your channel will prosper if you just keep up what you're doing, I can see you with a few million subs, easy.. There's definitely a bunch of people who like, comment, and subscribe because you mention you do that.
That connecting rod is twisted like my sense of humor, seriously check my favorites list. Great tear down!
Very interesting . I have a 94 Trans Am I bought new. It has the 350 LT1 engine. The engine has never been touched, aside from spark plug replacement every 100.000 miles. even the timing chain is original. 338.000 miles on it now, still runs and sounds like new. It uses no oil between 3000 mile oil changes which have been done since new. Castrol GTX. It doesn't smoke,, it has always passed the California emissions test. Lifelong Southern California car, it still looks great inside and out. And occasionally I'll give her the beans and she's still quite fast 😊
Anything LS1 or LT1 are a dream. I remember hearing a story that the engineers ran those engines on redline and it took days to finally give out .
Love the videos! My wife asks every time the sound of your impact in double time sounds like a light saver from star wars.
Thanks!! And thats from an old guy!! Built many Pontiac engines , Last one was the one in my 70 Judge, Have an 06 Grand Prix GXP as a driver and love driving her.. So very cool to see your teardown of this engine. As for the bent rod!! Very cool artifact.. would of loved to be in the cylinder wall to see that one happen..
I always try to figure out the failure mode as the video progresses, but I missed on this one a bit. With the engine turning (relatively easily) but water sitting on the valves, my first thought was that the valve train wasn't turning (stripped timing gear). But, then I could see the lifters move when you cranked it over with the head off. So, not that.
The "low" piston looked like classic hydrolock... only question is if it was water ingestion (unlikely with only one bent rod) or a blown head gasket from the apparently undertorqued head. Unless the hydrolocking stretched the head bolts, but that rod isn't bent enough to be a full-cylinder waterlog. So I would REALLY check that head out, because it may very well be warped, not from extreme heat, but from being undertorqued.
The bearing carnage though... so little sign of oil starvation up top, so much below. This has the looks of a high-mile bottom end that was a bit abused, then had a head job done (and timing chain) only to have been assembled poorly with a loose head and the resulting bent rod. Then they still tried to run it until it was condemned. I don't know factory LS head gaskets but those looked aftermarket. Or, another theory is that they popped a head gasket and hydrolocked it (bending the rod), had water in the oil and still tried to run it (hence bearing damage). Did a head gasket change to try and solve the problem but with the bent rod it never ran right, and was condemned.
I daily an 08 Impala SS, and even with having transmission issues left right, and center, I love the car to death and will drive it till I die.
I have an 07 ss and I feel the same, besides an oil leak coming from the valley plate gasket, the car has been pretty good to me and runs like a champ and is such a comfortable ride.
Really interesting that even on the most simple engines we’re always seeing or learning something new about them I’d really like to build one for my 96 Chevy blazer 4x4 since you can’t get that many performance parts for the 4.3
You can though they are essentially a 350 missing two cylinders so there's a lot of parts for them just not much when it comes to intakes but I do know if you have a carb 4.3 you can hack up a 350 carb intake and it will fit just have to plug the intake runners you don't use can't remember if it's front two or rear been awhile since I messed with one
Man after watching you do a teardown, I will never try to fix my LS engine if something should happen to it. Yes, it is a Silverado and an 05. It does run well due to synthetic oil and filter and every 3000 miles. Thanks for your video as it was very informative as to what it takes to do a teardown never mind a rebuilding. You must be a GM mechanic. I enjoyed your presentation- Thanks.
The pig mats I used in the fuel business rejected water specifically. You could literally separate water from diesel with those mats. Blue ones. The white mats absorbed all liquids.
The ones i buy are grey. Didn't even know they had others.. thanks mc master carr :(
Great, just pulled GXP in to replace the trans, and now you made a clear how-to that's tempting me to pull apart the bottom end.
Is there any other way to bend a rod besides injesting fluid in the cylinder? Watch all your videos,great job! Stay safe,Al
Run the engine out of oil and seize the rod bearing. The crank keeps spinning, the bearing stops bearing-ing, the rod starts to spin along with the crank, and now you have a banana rod. Or a two piece rod with half of it now bashing a hole in the block.
I have a 2006 Impala SS with 166K miles. Mine's not beat, I'm the original owner, I drive it like an adult and 80% highway. The car is not suitable for street racing, it is a 4-door sedan with good passing power. It has never done a burnout. That's how I drive it and I keep the engine oil changed regularly. The engine does consume some oil compared to my 2002 Avalanche iron block 5.3, but not terribly bad.
The transmission is still working well, I changed the factory fill and filter 6 years ago and everything looked clean in the pan. The engine is getting tired, has a little piston slap and lifter noise when cold. Still runs OK and the DOD has never malfunctioned. It does eat water pumps, it's on its 3rd one right now. I will restore the car soon and I have ordered a replacement crate engine from GM. They currently have a good PN for the replacement engine but had none in stock. My dealer parts guy (super parts guy) called GM's rebuild center and was told they had 1 core on hand and if they get an order for it they will fill it, but if no order comes soon then GM will probably discontinue the PN. So I put in the order for the crate engine. Lead time is 60 days, I told them to take their time.
I don't have any use for a bent connecting rod, and it's a good thing because I'm not gonna be able to come up with any teen tier sex jokes to get a thousand likes anyway, lol.
20:00 Was that a spun bearing, or a _sprung_ bearing?
That would be a spun, then sprung bearing.
So the real answer is......YES 😆 🤣 😂
Thank you so very much for doing a tear down of the LS4 fwd engine I requested you to do.!! I asked, and you replayed this video! Thanks again!
regards!
Denis
Those VLOMs aren’t that bad to replace. I just recently replaced the one in my ‘06 Impala SS that has just under 150k on it. Labor booked like 2.5 hours but I was able to get it done along with plugs, wires, trans service and an oil change all in that amount of time.
I bought a 2006 Impala SS brand new. I absolutely loved that car. Almost got it a turbo on it. It would have put out around 500hp, but I really didn't have the money for repairs if something broke. Damn I miss that car!
Those things are in a Life and death race with the transmission to see who can die a horrible death first.
Uh, no. This LS engine, just like the rest of them, is very reliable.
I've had a 2006 LS4 w/auto trans 4t 65E in an 88' Fiero GT since 06' , it's fabulous fun to drive👍 the FWD with shortened crank made it fit w/o toooooo many problems...lol..
"That's a lot of fluid."
I am shocked you haven't fitted some kind of drain pan support at the bottom of your engine block with how often these things leak all over your floors.
Or just a shop vac to empty the engines. It's faster to suck it out a port than off the floor. Replacement pans from x-large dog crates are perfect for the stand, wider than those pre-formed types & cheaper.
I have an earlier generation of that engine in my 00 Silverado, highly doubt I can tear down an engine as fast as you. Keep up the good work
0:20 it was GM's attempt to stay in the minds of enthusiasts while they got the Zeta platform ready. Problem was, by the time the W-car V8s were ready, the LX cars were already a thing.
@@mbsnyderc think you replied to the wrong comment, sir.
You make great videos. I watch right up to where they run ads that I can’t skip. I’d really like to see one of your videos to the end.
As others have already mentioned, this engine very likely experienced a hydro-lock. Good video of a slightly less-common failure mode.
How would that happen? Deep water or some other issue?
@@mikefoehr235 If the engine didn't didn't have plugs in it and the guy took it through a car wash or it sat in the rain or whatever it could have got in there.
Wow, right out of the gate with a Back to the Future quote? You savage.
I have found on these engines it’s the damn low tension piston rings that creates the oil burning issue. I turned my wife’s DOD off at 48k miles and it still burnt a quart every 2k miles. The EPA has put more of these engines in the junk yard than anything else. Better living through regulation.
It's just a bad design of the 2nd pressure relief valve, it plugs #7's oil control ring by spraying a LOT of oil into the cylinder. You have to un-stick those rings and get the updated pan even if you disable DOD.
LOVE ❤️ how simple these engines are 4 bolt valve covers 😍 👍 6 bolt mains lifter trays. Amazingly simple yet powerful with a power adder
Those T40s will be tight if some lamer drives them in with an impact instead of torqueing to spec
Dear sir, you are a scholar and a gentlemen. I enjoy watching your videos as they are a fun watch and to drink my tea with as i explain engines to my gf, who sometimes watches them with me. I love the carnage of the blown stuff and your humor as you explain. I'm an EJ man myself but very much realize they're short comings. A good day to you from Canada, eh
Isn't number seven supposed to be a lucky number?
Thanks for the video. I own a 08 super with 74000 miles. This is the first teardown I have seen on the motor. No problem with my Buick yet but....... .
Love your videos. The information you give as you show the parts and procedures all the way through is many times surprising. While I’ll never tear down an engine it’s all very interesting. I also like that you don’t pull punches on engine designs. I while never buy a car with DOD. Dumbest design mandated by our wonderful EPA.(morons) Ah well can’t wait for the next video.
“That’s a little shorter than it’s supposed to be, That’s what she said!” Best comment of the video!
“that rod was bent out of shape” - that’s what she said!
Also I had commented on one of your previous videos to do an LS4 idk if you saw it, but big thanks to you, you're helping a lot of people
Did anyone hear “meow” at
16:34
I just clicked your timestamp, and meow I hear it.
I used to have one of these thank goodness I didn’t have it long enough for any problems to develop.
That was a political connecting rod. Crooked in every way possible.
I love the sound the breakerbar makes on 1st crack
These engines are junk..I had one in a 08 Impala SS. tick tick tick tick tick tick tick...went through 3 of them. Tick tick tick tick tick. It would scoot though, even with the automatic
Looks like a hydrolocked cylinder... I did that to a '92 Toyota Hilux while on a typically long Australian road trip. I did get it started and apart from slight vibration, the ol Toyota got me home and to work for a week before a rebuild was decided on.
A front wheel drive V8? You yanks must have strong wrists. Can those second gear burnouts be done it a straight line?
Thank you. Unveiling the mysterious LS engine. A good straight forward autopsy of the little mouse.
These videos are a good resource to learn about what could possibly go wrong internally when you don't take care of an engine, if nothing else... This one may not be a case of poor maintenance per se, but it clearly saw some condition it shouldn't have. It's interesting to me, in technical terms, how the smallest bend in a component such as a con-rod can cause so much to go wrong. Some very interesting content in all these videos. Keep up the good work 🙂
Yooo awesome teardown. Just got my Monte Carlo SS too so probably will be coming back to this in the future
I had a 2007 Monte Carlo SS with that engine and it was alot faster than people would give it credit for. Not the fastest thing on the road but alot of fun. Especially when people thought the last gen mcss was slow, open that thing up and it would walk away from alot of cars that was surprising.
I have about 220000 miles on my LS4 engine. Working on my second transmission though,Lol. That was a cool teardown to watch.
I like all the autopsy videos, even the ones about engines I know I will never work on.
I like how You every time spilling the coolant and oil directly to garage floor and not having any oil pan laying down the engine. Pretty much my style.
А я все-таки стараюсь какой-нить кошачий сральник подставлять, скользко же потом:) Вчера разбирал мотор от Эксплорера, ни капли на пол не ушло:)
Anyone that has one of these that is burning oil and smoking out the exhausts (valve guides)! Try some AT-205 from ATP! It worked magic on mine. A few ounces with every oil change will cause it to burn no oil whatsoever. GM should have included a case of this stuff with every car! This might have saved this engine.
I’m not sure where to write for requests but I’d love to see the mighty 496/8.1 torn down.
Thanks for your show,.. I oddly find it relaxing 😎
All of those 1920s technology rods look just fine.
