This is one of the best instructional videos I have ever seen. Being a retired GM mechanic I am completely impressed with your video. Great job guys. Great job.
But how does the rocker arms be torque down do you just torque them down or got to position the cam to tdc ? Or its just like out them on and torque them to spec?
Why can’t every instructional video be this good!! Thank you guys! Simple and to the point. Perfect
Right?
I just completed mine with the help of your video, great job. I have a couple friends that worked at Chevy. They made a good point to make sure where the head bolts go into are COMPLETELY dry. If not, any water, coolant in the holes will expand and crack the block. They have seen it plenty of times. I would of never even thought of that. Use lots of air and make sure they are DRY.
Did you need to do anything with the timing or no?
@@andycampos9223 nope, another great feature of this motor.
You need an angle torque wrench, can't do it without it. Maybe rental places, if not they're about $200. make sure you replace all bolts with new ones. Exhaust manifolds, intake manifold, etc etc.
Take lots of pictures as references. They come in handy.
Lube the bolts good , and no u don't need a special torque wrench , tty , just use ur brain
This was likely the single best how-to video I've ever seen. It's definitely worth the watch.
It was about 9 minutes into it that I realized exactly how lazy I've become and that I would just rather sell my truck 😂
For me it was 5:16
Bout half way their sir
6 mins for me 😅
@@tali6an6oggey2 good for both of you, 4:03 here
about the 7 min mark for me. physically tore my engine down too. now I'm overwhelmed, in over my head and calling the salvage yard first thing tomorrow to come pick up my truck
Excellent video. The only part that seems unrealistic is the complete absence of obscenities. 😄
😂😂
Great video. Helped out this weekend. From tear down to start up was about 12hours. I don’t have power tools so everything was by hand but this was definitely an easier repair than what I was expecting. Took lots of pics for when I had to put everything back. Thank you for taking the time to do this video. Saved me a lot of money and having to miss work.
Shit im working on my 08 suburban with a 5.3 i believe there is oil seeping in from the head gasket by cylinder # 1 front driver side.
I took off all the spark plugs on the driver side and they were wet with oil. And while it was running the oil pressure was as low as 15 psi
Seriously this is the perfect instruction video. No bs, straight to the point. The world would be a better place with more people like you guys. Lol
Went to 4 different web sites on torque spec and got 4 different answers. Thanks for the video!
Best instructional video on head gasket replacement ever made. 👌. Thank you so much you guys. Both of you are amazing!!
Thanks for this video. I know it’s 3 yrs ago but still very helpful. For those of you doing this job, you may as well change the oil pressure sensor while you have the intake off, even if you don’t need one. It WILL leak or fail eventually. Thanks again!
Go on fam😂 you’ll be the reason they mess up let them do that first
Reviewing your video for head gasket process, I notice something that might help you which I learned when I did intake manifold gaskets a few years ago. When the wiring harness is hanging in the way of the intake - I used bungee cords to pull it out of the way and it worked great. It was hovering above the engine and I had plenty of clearance for the manifold.
Perfect. I’m used to doing my own work and rather than send to a professional who will take shortcuts and eventually fail prematurely. I will do it myself and only blame myself if anything happens. It’s a great time to freshen the heads, add heavier duty springs, rocker, maybe a set of headers. Thank you for a great video
Looks a bit intimidating but I like cm taking into a challenge and thanks to you guys I think I can pull this off.
Great video. Thanks!
This gave me motivation thank u guys
Awesome job. Really appreciate it. Well laid out this is the next step on my suburban. Be blessed guys. Richard Iowa.
Amazing video. You're a great instructor. Gonna attempt this soon when I get the time
I love how you don’t have to mess with the timing chain on over head valve engines
This is an excellent video! Extremely easy to follow along. I am getting wiffs of coolant on my 03 pickup I purchased a week ago. I feel this is in my future, stopped by to see the “ease” of this. Your video gives me great confidence in doing a head job now. THANK YOU
My wife does my head jobs for me and I return the favor at times too. 🤙🤓
I just had to replace my radiator in my 06. Pretty common for the plastic end tank on the radiators to crack near the driver side coolant hose. Was smelling coolant for a long while before it completely failed and produced coolant showers.
Thank you for the video. I got mine apart in 3 hours but I have a broken collarbone and a couple ribs 🤕
That’s probbaly the best trick I’ve seen with the extension with the hammer for the clutch fan
Replace those knock sensors while you're at it.
Simple and to the point no extra BS thank you
You guys made it look easy great work 👍
Huge help. I have a 2006 Silverado with a 4.8 and the 706 heads. Replaced the head gaskets at 200,000 miles but they didn’t shave the heads and they are no warped and need replaced at 240,000. Got them off rockauto for a heck of a deal. Thanks for the help and step by step info!
You’re welcome.
I have a quick question. If you remove the heads do you have to take them to a machine shop? I need to replace my lifters because they’re ticking so I need to remove the heads but I don’t know if I have to take them to a machine shop.
@@michaelcochetti3049 its recommended so that the heads are flat and if there are any imperfections the machine shop will take off. Plus, more peace of mind imo
@@cristianquinones1249 sorry if i asked dump questions. If the heads are taken to the shop and flatted by any machine work, what about the block surfuce? Should we keep them consistent if we can? How do we know if the block surface is fine while the heads are perfectly falt? Thank you in advance
@@vampirel1983 You won't know unless you take the block in as well but being that the block is cast iron(?) I believe and the heads are aluminum it's much more likely for the heads to develop a warp/imperfection than the block.
Very good video, going to do it on my truck. Have done all the maintenance on it. Should be straightforward, thank you guys for this great video 💯
Such a good video. 3rd time using it now lol! Great job guys, thanks!!
Man thank you so much I dint know how to take off everything and put back to place a freez plug tutorial next 😅
I've always made good time on these jobs but damn! You guys are fast! Nice video
Nicely done. Thank you.
Brother you saved me on this video!! Thank you! Next project!!!
just wanted to thank you for great video and instructions thumbs up
Excellent video thank you so much!
I got a 03 Yukon with the 5.3. I was thinking today that I would take it to a shop to have new gaskets installed + oil/coolant changes.
After watching this video I honestly think I could pull this off on my own as long as
1) I am patient (I tend to ruin stuff when I rush)
2) Good weather (I'll be in my driveway)
And 3) I have the proper tools (I'll need a torque wrench and that fuel line tool)
How did the job go? Did you attempt it?
Just be careful those head bolts tend to break. Now I'm scared to even mess with mine if it goes. I replaced my whole motor cause a bolt broke below the deck
Thanks brother for this video
Haves help me a lot keep it up bro
Ur the
Great job very well explained 👍
EXCELLENT VIDEO GUYS ! THANK YOU !!!!!
Very detailed amazing job
This was an amazing video, I have a 2005 Chevy avalanche that needs this type of work unfortunately I'm not that mechanically inclined, changing oil changing batteries spark plugs filters those things I can do but it seems these boys are top-notch 👍🏾, I think my best bet is just to buy another engine 🤣🤣🤣, and swallow the bullet on the labor cost 😲
nice about to do this to my truck, this is going to help a lot, Thanks!!
Thanks. This will help me a lot.I'm just wondering about intake gasket.you guys didn't mention it.
Excellent video thanks for sharing!
What works for me is to tie a strap on the exhaust manifold to the wheel it will separate from the engine & you'll be able to remove the head 😁😀
By turning the wheel it pulls it away? Is that what you are saying?
Great video I was gonna do it myself now just gonna get a mechanic lol 😆 😅
One thing I’m going to add is mark your pushrods they HAVE TO GO BACK in the same place especially if you have some miles on the rig they all will have wear patterns and it would be very beneficial they go back right where they came from
Excellent work 🍻
Great video guys 👍
Update***
Again, Thanks for making this video, it really helped me out!
This video helped me out a lot but I had 1/64 the luck you had. Thanks for making this video. Took about 15 hours. I snapped the heads off all the exhaust bolts, had to sawzall 1 of 3 exhaust bolts to get the passenger exhaust manifold off(no possible to get the driver side manifold off, dip stick housing thing came right off after I unbolted it from the head (still dont know how I'm getting that out), my coolant cross over ( which went under the intake manifold and to the back of the motor) crumbled to pieces, the knock sensors turned to dust. I have a 2000 Silverado 1500 5.3l 150,850 miles.
Got the motor cleaned up and all back together, runs great. I used enginetech remanufactured 862 heads, new head bolts, miele multilayer steel head gasket, updated throttle body gaskets and replaced a lot of other parts
Mike S wow
Mike. Sounds like you're from New York.. Or at least the truck is...
Haha I was looking for this comment. They made it look easy and didn't talk about how bridle the bolts are on this
My twin brother has this truck, he says that the instructional video is amazing but the music doesn’t make the work any less intimidating.
Wow I replace head gaste in a Camry that was a job this LS engine is super easy maybe the only problem is you have broken bolts in the exhaust manifolds. But you guys did and awesome job in the truck and the video. Thank you very much but I don’t see any beer through the whole process 😂😂
this was great, however there was only one really big issue that I came across. The Buick Rainier/Chevy Trail blazer have this same engine. The compartment is much smaller and working around the exhaust manifold is a huge pain. A huge exercise in patience.
Love the video, hate the music. Thanks brother! 👍🏻🇺🇸
Awesome video 🤝🏾
Thanks guys!! 👍🏽👍🏽🙏🙏
Great Video, Thanks
very good informational video
Very good video, want to do my sierra , butblooks a lil intimidating.
Same 😂😂 just gotta have the tools and follow the steps
I got my head gaskets and everything replaced and that all worked out great but you forgot to mention that the rockers need special adjusting when you put them back in and I didn’t do that and now my rockers sound like shit
Howd u fix it?!
Thank you!
Hi I have a 2005 Sierra v8 5.3L head small leak on driver side head did you resurface head or just put the head gasket not sure if I need to do that . Looking forward thank you
Thank you so much.
Great video I have a 2011 Silverado 5.3 I'm looking into doing an afm delete kit what would be the cost to have it done with you guys I'm in salinas ca.
About to start mine on my 2000 suburban its misfiring barely running but loses water out tailpipe so about to put two new heads on and see how she runs afterwards.
How did it go ??
Very good video
In need of replacing my head gaskets this video was very helpful thank you brother
Had a 2005 aka 2004 built Silverado, till the head gasket blew on me April Fools Day!~ Only 167,000 Miles, but got it with 57K miles in 2007 from my brother.
Caused the power steering & braking system to fail at the same time, happened while driving and ended up in a cemetery easement.
Love the happy toddler music. Surprised u guys aren’t making glitter slime
Great video
Do yourself a favor and take lots of pics. It makes reassembly much easier. Great vid guys.
Should have done the lifters while you had the heads off. I'm amazed none of those exhaust manifold bolts broke.
That's only an issue on 6.0l. the 4.8 and 5.3 are way way less common. Every 6.0 I've seen has the back bolt broken off
This is by far the best video I've seen on this job. I have to pull the heads off because I need to change the lifters. Only thing is I have the 6.0 engine. are there going to be any differences for me?
Pretty much same
@@gasketmasters cool, thanks. Just ordered my parts. Wish me luck.
Awesome video… my only reason to look at a additional video is because I wouldn’t know about securing the rocker arms correctly. 🥴
I'm working on my 08' 5.3 suburban with DOD... I took off all the spark plugs from the driver side and they were all wet with oil. And there is oil leaking on the front driver side of the head between the block and the head where cylinder #1 is at.
And my oil pressure was at 20psi and lower while i was running it
What do you torque the rocker arm bolts to?
It’s a good idea to replace the oil pressure sending unit & filter while the intake is off.
Why? Just curious
I was looking to see how you guys address the coolant on the head bolts holes, also how to do the valve lash.
So when did we talk about the intake gaskets? Thanks for the video!
Do you need a tune up after installing new cylinders heads? Even if they have the same AFR , would you still need a tune since it’s a new cylinder head with a different compression rate or , you can just swap the cylinder head an it be perfectly fine?
Great video, only thing I would suggest is to get rid of the background music that was playing.
Great job explaining. I think I am going to have to do this soon. I am slowly losing coolant and I think my truck has the Castec 706 faulty heads. Going to have to replace both heads. Just curious how many miles on the truck. Thx
Do it as soon as you can. Small leaks turn into big leaks. Big leaks turn into overheating.
224,000
What kind of heads do you put to replace the 706? I have a 2005 Tahoe with that heads and i think the head gasket is not good, so I want to replace the heads too
@@gasketmasters Learned that one the hard way, changed the water pump, fixed it for a bit, then coolant came pouring from my exhaust
Hey guys great job! One question tho. Do you guys do anything with timing ( top of center) like other engines?
No , just do what they did, no need to put it on TDC
I get this was done a long time ago, but if you guys are still around, I did this job got everything back together, I started the engine but it immediately stalled. Did some research, and found a number of things it could be, but what would you guys think is a possible issue?
Great vid. Do you use new head bolts when you change the gaskets?
Thank you
Thanks, I just discovered your channel. My question is, do you have to adjust the rockers? Thanks
will it make any difference on spraying Cooper silicone on the head gaskets? just wondering... thank you in advance...you're awesome 👌
NEVER use that on a multilayer steel head gasket. It will fail within a month or so
Did you also replace the intake gaskets?
Excellent vedio I have to do the same to my suburban it has lifter noise badly i don't have miss fire or lost of oil pressure or no lost of power is lifters people tell me oil pressure is perfect i can i chech or find out if is really lifters can you boy's help out thank you very much.
Soo what did you do to clean up the old gasket material on the block
use a razor blade and try not to score the gasket surface so the new gasket will seal correctly and not leak.
so none of the head bolts broke???? dayum!! great vid yall, thanks!
what ft/lbs did you tighten the rocker arm bolts to? is there any valve lash adjustment?
Are theses specs any different for an LS2?
When you put rocker arms in did ya torque them ? If so how much and do ya have to rotate the cam or just torque em all down
the Haynes manual shows to rotate the cam, and torque to specific on the intake stroke if I remember, its been a long time since I did mine, should be lots of tutorials on here for it
Good shit
How much do you torque down the rocker arm bolts to?
when placing the valves back on did you have to reset the gap?
How much did u guys charge for the head gasket job?
Hey can I still access head gaskets without removing alternator, belt and and exhaust bolts
Awesome job guys .!! Bravo.How did you guys clean the heads to make them looks that clean ?
I don’t think so they probably take those heads to a shop for resurface and naive a valve job
I am guessing that this would be similar for a 2000 LT?
