The struggle is real. Thanks for keeping these videos true to the experience.

My buddy’s grandfather had a 2009 Chevy Silverado with the 5.3L. He had the heads redone some years ago and all of a sudden he developed a tick and a skip on the right bank. So I pulled the head on it, thinking it was a lifter as well. Well, lo and behold, when I removed the head and turned it over, one of the valve seats was cocked sideways. So pulled the other head off and took them to the shop that had done the heads previously and the redid them again at no costs.

I've got a 2003 Yukon XL and I love it. 302k miles and still going strong. No AFM/DOD to worry about, all the luxury features, and has a great look to it.

I usually just use my cordless shop vac to clean out the bolt holes

Gmt800 vs 900 💪🏾

I would feel sick learning that I had just popped the cooling jacket, however that is a very easy mistake to make though for a backyard mechanic.

Best introduction ever. !!!!

Great video man. Appreciate the time you’re taking with this one.

Just finished the first 2 and boom here you go with the third, thanks Matt

800 vs 900 would be great, I have an 05 Escalade, considering a move to an 09

Exceptional work on the video! It exceeded expectations in both content and presentation.

Great video. Thanks!

Thanks for showing that everybody screws up from time to time

Thanks for the videos. I have a 2010 Escalade and have a little ticking I’m considering doing the work myself after watching your videos

Good video and thanks for not taking out the parts of making mistakes. Cuz we know we all do it

Matt, so glad I found this series. I just found me a 2010 Escalade ESV with 156K very similar to yours. And I know nothing about Cadillacs. First time owner. but I wanted that 6.2L 6L80 platform for a mild RV, trailer hauler. I plan to do similar upgrades and repairs. this series is so very helpful for me to understand some of the issues I know and may not know about this unit.

I’ve seen that on some of the older dodge 3.7 and 4.7 heads before. I’ve had one in the shop that would miss for awhile then occasionally the spring pressure would pull the seat back up to where it would stop missing for a bit until it fell again.

My 07 Yukon Denali did the same thing. Holding out for some 821 heads.

Awesome videos. I’m here for Tahiti and auction Escalade content

I have an 02 avalanche runs like a dream No dod bit of rust on one rocker. I take good care of it. Done a lot to it. I’m looking to get a 2011 Tahoe but I’m just scared of all the sensors and dod and doohickeys. Funny as a kid On Long Island I had an 82 trans am 350 I would love to have that car today with an LS. I enjoy your videos I can relate a lot thank you.

Another great video Matt! We all have those "shouldn't be working on cars today" days.. Unfortunately, sometimes, they happen for more than one day in a week. Lol. Hopefully that K & N filter is a dry one, the oiled filters can cause MAF problems with oil polluting them. I'm jealous as hell of your Esky! That thing is beautiful! I just bought my daughter an '04 Tahoe, and to meet my budget, it's a pretty rough one. 300+k... but hopefully it will last her a while with some upkeep and maintenance. The GMT800 (lazyboy) seats are definitely superior to the GMT900 cardboard. Keep up the great work!

Gen 3 truck blocks 99-03 have shorter bolts on the outside 2 in the middle. The gen4 blocks and the transitional ones that are 04-06 that have the gen4 rods and pistons have all of the big bolts the same size. Its a crapshoot on some of those blocks though. Bummer on not blowing out the holes, its an important step, I always run a thread chaser as well... The rectangle port heads have the offset intake rockers and the cathedral ports have all straight. Also, the coil packs determine the plug wire lengths, the round ones are shorter and need longer plug wires and which ones you have are determined by which shipment they got... It looks like your escalade didn't have the tow package or desert cooler aux cooler and someone added the one cooler and didn't spring for new oem lines to the back it looks like the didn't know what they were doing on the install but if you use the right hose and put the clips in your good.

For the cup holders in Tahiti, get some 3 inch Fernco couplers, cut the ends off where the clamps go. Then cut them vertically, and press them into place.

Yes

Great video Matt! Weird that we both lost footage for the same video. For different reasons though lol glad to see it running.

I see you like the French vanilla assembly lube. I usually like the raspberry jam flavor.

I have the same truck i got rid of the air bags and converted it to coil springs and never looked back now it rides like a Tahoe lol

Hi mat I'm new to your channel wish you so much luck on your build 😊

Appreciate the transparency tho 🫡🏁

Definitely, you’ll get a little rubbing with the all-terrain tires same thing with my Tahoe

Matt, I have a hummer h2 with the same exact engine and a Magnuson supercharger. 135,000 on the clock. I’m looking into doing a cam and valve springs. I have learned a lot from your videos and I want to thank you for making these mistakes so I don’t have to. 100% I would have ended up with 32 cracked head bolt holes had I not seen this😂 I’m hoping I don’t have any issues anytime soon with all the Offroad driving and towing I do. As a broke 19 year old and with the price of gas I would definitely be put under.

The door codes are likely due to a shorted wire in the boot between the chassis and door. Had a Yukon that had 17 codes for the passenger door. Discovered a bare wire.

Progress for the win. Love me some V8.

Good vod

Don't you just like when a quick fix on a daily driver ends up taking a "little" bit longer than expected? My Caprice wagon has been on jackstands for 2 weeks as a 30 minute fix turned to removing the cowl, lower dash, inner fender and half the interior...

Instead of blowing the water out of the bolt holes, try to tape up a small tube/hose/straw to the hose on a small shop vac and suck the liquid out. Blowing the air out with the head on is just too far for the compressed air to displace the water/coolant.

Dropped valve seats was super common on pre Eagle 5.7 Hemis

That mag ride life replacement prices hurt. But they are worth it. You can get Arrnot brand replacements cheaper and they are the factory bwi shocks.

I just brought one of these gmt900 Yukons

Oof! I’ve replaced the heads 5 times on LS engines and the most time I spent on any one task was cleaning the bolt holes. Thread chaser, brake clean, long cotton swabs, compressed air, more brake clean, the compressed air again. Probably wasn’t totally necessary but I was a bit paranoid about messing the block up. Sorry, dude.

you have to have the plastic safety clips over the trans/oil quick connects or it can blow out as it did on you.

They probably had their line start leaking like mine did and decided to do a DIY fix instead of relaxing them all together.

Done lots of these usually the coolant just pops past the bolts when tightening them down. Probably had a weak passage to begin with.

Those electronic shocks get firmer/harder when they go bad.

Love to see a video on the comparisons. I have an 04 z71 suburban but i have been interested in a newer and if it's worth 1 like yours.

There are so many things that can trigger that damn traction control and Stabilitrak. I HATE IT!!! I had a leak on one shocks in the back on our suburban and just took the air ride out and put regular struts in.

Do a video on the shocks/struts!

Sweet

Usually plastic lock rings that go over those sketchy clips… i had mine pop off at the trans because the plastic rings werent over them

The suspension is probably those damn magnetic ride control shocks. When they go bad they ride HARD!

Ebay is the best for cheap alternators and starters….they last just as long as the parts house pieces as well but only cost around $50

Nice job so far, except for the one part anyway

The cheap mag ride shocks off amazon seem to hold up. About 2 years on mine an ride good.

Some people!! As my Father always said, if you are going to do it, do it right the first time.

Yikes. I decided to ask why you didn't just buy a brand new set of LS3 heads, then I saw how much they went up in price! About $800/head now. When I built my 6.0 about 15 years ago, LS3 heads were $330/each right from GM... fully assembled.

Not sure if you have Blain's farm and fleet by you, but here in Michigan, their brand brake cleaner is made by CRC. same can, just different label. They only charge 2.99 a can too. I love supertech brake clean but it went up to 3.50 a can here. Just an fyi lol

I mean if you do do boost I mean you should probably do a cam I know I don't have an extra $400 but a truck Norris cam would have been real cool

Ik the front struts are pricey i did the ones on my escalade and there like 400 on amazon its crazy but i figure if i wanted a suburban i would of bought one i like the air ride / eletric ride it makes it float🤣!

You remind me of, well, me! 🤣

Awesome. Been a long time subscriber. If you don't mind me asking, what do you do for a living?

Awesome video as always Matt. Quick question, what did you use on the surface rust on your cylinder walls?

the video description reads like a dragon ball z episode

FYI, I actually got new transmission lines for my Tahoe from Summit racing believe it or not they sell regular parts also

I've got one of these Escalade's and just recently both cylinder banks started running lean, and the battery is dying overnight. Can't for the life of me figure it out, but when they run they sure are nice.

What ODBII reader do you use?

What engine code reader do you have/use??

Hey man. I have a 2007 Escalade ESV and a 2003 Yukon SLT. The Escalade is the same color as yours. I bought it for $4500.00. Put another $4000.00 into it. Right now my main concern is an oil leak.

I'm curious about all that valve float. Really wanting to know what could be causing that. I'd like to think that even driving hard that the LS would be able to handle the 5600RPM it'd be seeing

I don’t think many of the GMT900 suvs came with external transmission coolers installed from the factory? Maybe this was an well-intentioned but poorly executed addition by the previous owner. I know my 2011 Yukon (with tow package) does not have an external trans cooler.

I recently picked up a ‘13 Escalade it has aftermarket wheels (which aren’t too bad) but they have those stupid spikes as lug nuts, what lug nuts can I replace them with?

Maybe I'm wrong but shouldn't there be exhaust manifold gaskets?

Need me some Turbo Taheti.

Everytime I think your luck turned around boom u get hit with more bad luck lol had days like that I stopped and the next day it's till went bad lol

💪💪💪💪

As an Escalade owner sounds like the the air system is crashing. Be prepared for heart surgery when you price shocks. For my older Escalade an 03 the rear alone are 300 a side. Good luck

GM Should have made the L92 an Iron Block

The mirror motors crap out. Easy to just replace the motor itself.

What code scanner plug in that you use that you can see on your phone?

Hey Matt, any idea when we will get a Tahoe update in the future?

You gave up on Tahiti 😢

What’s the difference between the cost of rebuilding your old heads and buying new ones?

Bring it to my house. I’ll help you wash it. I got everything pressure washers steam machines 18,000 different chemicals D a polishers rotary polishers you name it.

Do it nice or do it twice

what happen to tahiti? you selling it? im interested

Is this a repo? PO knew car was going bye bye so he put a brick on the gas pedal. Just revved the living crap out of it.

I think people's concern about automatic car washes is over stated and kinda nonsense maybe there was an old different design that did what they say but I don't know it's fine today

Magride shocks are going to cost you

These didn't come with DOD btw

طولت على ماتنزل ذا الفيديو

Remember what I said? 😂 I have had those days omg brought back some memories…

double clamps they are cheap

That motor is so crusty

That’s the shitty thing about Staten Island bro

Gmt800>gmt900

Hey Matt, I’m not trying to be like rude or nothing but it doesn’t deserve the hackery. That was done. Them damn trans cooler lines. Been there done that. Hackery is why shit junk failed. I say you do junk, you deserves junk. Correct trans cooler lines on there would be better. Nothing lasts forever and it’s not its fault it was taken care of like shit.

What scan tool adapter/app are you using?
