About time someone just posts a timelapse of taking the motor apart! Great job dude. It would've been a little better if you added some comments at the end, but still one of the best disassembly vids out here.

hola, no se hablar ingles, pero me has salvado la vida, llevaba 3 días intentando sacar un sensor de detonación que estaba despedazado, y encontré tu video y me di cuenta que se podía sacar la tapa del pleno sin sacar los sensores y gracias a eso pude sacar los sensores de detonación, mil gracias. Hice un video de como cambiarlos. Saludos y gracias.

No problemo, amigo. Me alegra que pueda ayudarte.

awesome video!!! Great content . I am currently finishing my 5.3 for my 91 Camaro.

[@CaliSwaqqPopper]

Do you have fb to share progress? - would like to share :)

[@AcerArtsOfficial]

What dont you like about the drive by wire throttle body? I like it, it seems like its less likely to fail compared to a computer doing it

[@martyno8696]

I have the L33 in my 05 Sierra. I plan to do a rebuild on it eventually so I really appreciate the video of the tear down.

[@rosskrause3926]

Thats the exact engine,block and heads I want but can only find lots of the iron truck blocks around here..I will save up and maybe get lucky one day and find one..nice video !

[@ScorpionBear_AG]

Iron blocks are great man! Just slap different heads, intake, etc etc and you are in for a great time and a great engine!!

[@LSCHEVYRYDER254]

awesome vid

[@bullyelfuerte]

Awesome video 👌🔥

[@deankay4434]

For everyone using cast iron exhaust manifolds & I would say headers as well, tip. Elongate both end flange holes and use a flat washer. The 2:1 expansion and contraction difference from iron/steel to aluminum will often break end bolt or stud. You see this a lot on the donor engines. This just helps reduce the future chance of that headache. Seen both, Dealer Tech. ASE Master Tech-Retired

[@joedanero5360]

Do you mean open up the outer manifold holes and use washers?

[@deankay4434]

Joe danero Yes! The outer ends of the exhaust manifold(s) studs or bolts have to move as the aluminum heads moves. This is why they like the torque to yield head bolts as these help maintain clamping force. Something has to give. Rather than loose a head gasket, the end bolt breaks. I had 4 cylinder engines that the rear stud broke all of the time. So I would have to drill or if lucky, unscrew the stud if stick out. Rat tail files are hard but brittle, so I had several short ones. I found it quick to chuck in a drill and oblong the hole. Using a flat washer under the head of the bolt/stud, simply allowed the stud to slide on the exhaust manifold. By doing this, it never failed again. Unless you see the “LS” family engine everyday, look at these bolts the next time you walk thru the salvage yard. It seems that 9 of 10 engines had bolts broken off on both ends. It is only my suggestion as the Tahoe I inherited (Son hit black ice) all 4 corners were broke. I didn’t think twice about what I was going to do, even with stainless steel headers I eventually got. I use anti-seize on everything and dielectric grease if electric. Does this make sense? It is my experience guided by results.

[@videos-for-friends]

There’s probably a lot of questions I could probe you with… lol

[@deankay4434]

@@videos-for-friends Ask! I have seen and learned a lot on imports, domestics and working with GM. What I say imports, I mean British, Swedish, German, DeLoreon, Italian, Japanese, etc. Ever heard of the Nissan Patrol or Presidential? Adjust valves on a 12 cylinder Jag? Pre-War Pontiac, Plymouth and Ford repairs! Then let’s repair Farm equipment as tractor are split into 3 parts, hay equipment has one belt is 19 feet long and runs down the middle, School bus clutches & king pins on straight axles. Yamaha dealer tech, bore Harley cylinders or cut valves and seats with tungsten carbide cutters up to 2.2 inches to 0.6 inch. You need the correct pilots of course. CIS fuel injection, carbs from every side draft, down draft, up draft and sync multiples? Ask.

[@dragonsbreath1984]

Interesting. I have a 2004 Sierra with the LM7. I installed Gibson SS headers when the truck had less than 5000 on it. It now has 250K on it and I recently replaced both cylinder heads. Not one cracked bolt! The Gibson headers have a lot of bolt hole play. Seams to support your theory.

[@jacksmith3189]

Excellent video Thanks

[@dennisgray563]

Think I would’ve cleaned all the bones and shit off the engine before opening it up

[@cjhill726]

I have the same engine with the same mileage and same tick in my truck. Guessing this is what it probably looks like taken apart.

[@bwspacity]

Info on that red electric ratchet?

[@6slayer6sam62]

I got found an L33 on eBay the other day and turns out it was at a yard 30mi from me. Has 314k on it but I got it and the computer for 750! Going to put it in my ZQ8 s10.

[@twistedtrail8414]

Anybody know what part number for a rebuild kit on the l33? Or is it the same as the lm7?

[@warrenlancaster8045]

Same as any gen 3 LSx. Just an aluminum block, gen 4 rods, 4.8 flat top pistons and a slightly higher lift and duration cam.

[@drtb69]

I liked how the vvt valley sensors went bye bye after fooking with em for a bit.

[@JohnBrowningsGhost]

Fairly certain those are knock sensors.

[@repr26]

These engines came from the factory with lifter noise. And piston slap.

[@joedanero5360]

lol. And lets not forget overbuilt for their factory output.

[@jacobynoctis4825]

Keep up with maintaince and you should get plenty :)

[@RobertSmith-le8wp]

There’s a few million mile ones out there, and many many many with over 500,000. I’d say 300,000 is a walk in the park. If you even halfway take care of it you’ll be fine. I’ve seen poorly maintained ones with 250,000 that run perfect. My brother has a GMC with the 5.3 and he forgets to change the oil all the time and has gone over 20,000 between changes at times

[@deankay4434]

@Joseph Ornelas The shipping weight is 98 pounds difference between iron to aluminum. The L59 is flex-fuel with 33lb/hr injectors using stainless alloy fuel line where the balance is plastic. Fuel pump is “Robust” design with different p/n. ASE Master Tech-Retired

[@joedanero5360]

The L33 also has flat top pistons and a HO oil pump. Not to forget the 243/799 heads, gen3 reluctor and cam pole, gen4 floating wrist pins, gen4 connecting rods, and the three bolt cam for the earlier years.
