I have never seen a Mechanic do such a big job, without cursing!
He did off video I could almost guarantee it. There is A LOT more to it than what the video shows
yeah but the background music hes using sounds cursed
Maybe he never joined the navy.
I bet 1,000 he do 😂
I may have missed it if they mentioned it but keep in mind, if you have the Theft Lock system in your truck, having your battery disconnected for a length of time will cause the anti- theft system to reset. When you try to start the truck, the computer will disable the fuel pump and it will try but not start - making you think something else is wrong. You will have to simply do the relearn procedure. It's easy and takes 30 minutes. Google it if you want but you basically insert the key and turn the ignition to on without turning over the engine. Leave it there for 10 minutes. Then turn the ignition to off for 10 seconds. Back to on position, then off for 10 seconds. Back on for 10 minutes, then off for 10 seconds. After 3 cycles of this, as long as your distributor is installed properly and all else is good, the truck should start. I learned this when one of my kids left a light on in my Tahoe once and I didn't drive it for a week - had to reset the security system. Future plans are to take it to a tuning shop and reprogram the computer to NOT have the anti-theft system as that system can create quite a headache if and when it malfunctions.
That’s gonna take me about 3 weeks to finish everyday day after work
Money saved tho will be worth it
@@dmack177 legend has it he's still working on it in increments to this day.
Lol I kkr I've gotta do this to my 00 escalade after replacing all the coolant system only thing left lol
Lol I’m literally on week two of my head gasket change on my 350. I will probably take two more weeks because I work five 12’s per week.
@@ScaleModelAddicts I feel you🤣
THANK YOU TONS, I JUST SWAPPED MY 350 TO 305(ALL i COULD FIND AT THE TIME)BUT BLEW HEAD GASKET AS NEED TO GET DIFFERENT SHROUD TO FIT, SO WENT WITHOUT IT COUPLE DAYS IN HEAT AND BLEW IT. SO NOW, I HAVE TO HANDLE THIS NICE NEW JOB...BUT HEY YOUR VIDEO AND THE IDEA OF USING CUTOUTS FOR ALL BOLTS AND ROCKERS, ETC IN THE RIGHT PLACES FOR RE-INSTALLING...FREAKING AWESOME IDEA
THANK YOU TONS, LOOKS LIKE I HAVE ME SATURDAY PLANNED NOW!! AND YES I'M A GIRL WHOM LOVES WORKING ON HER OWN 1980 CHEVY K5 BLAZER!!!

We thought we were going to have to pay a shop $4000 to do this job. It ended up being around $200 thanks to this video. We did break an exhaust bolt and strip a distributor screw, but other than that, a fresh oil change after the job & she fired right up with ZERO issues. Thank you. We finished the job in one weekend and he was able to take his truck to work. He works at Auto-Zone and all the fellas there were telling him the truck isn’t worth keeping for the amount it would cost to fix. A1 Auto just earned my business. Sorry Autozone
Very well planned and executed. Tips , cautions and explanations very much appreciated. Excellent camera work!
This is an outstanding video! Thank you so much for the comprehensive walk through! Videos like this are what makes RUclips one of the most valuable tools in the modern world. Thank you 1A Auto, you earned a customer and a subscriber!
Thanks for the video. I just had a head gasket blow on my 97, with 324k miles. You're a lifesaver.
Excellent job, very detailed and well spoken! I look forward to more of his videos
I watch a lot of videos and this is been the best so far on replacing a head gasket
The Mechanic who did the work and also the narrative was excellent
Im impressed
very good video .
you guys made it clear real good job
I just became a regular viewer after watching this video
looking forward to seeing others now
Im a subscriber as of now
thank you
Thanks bro i finally git through this video today lol dont know why it takes me a week,and 600 play,rewind,play and im done pfffeewww...really cant thank you enough guys yall saved me big bucks and i trust my work more than others sooooooo yeah thx guys....
Thank you so very much your video has to be one of the best videos ever created on how to replace a head gasket.
+Henry Gonzalez Thanks for watching, glad we could help!
Agreed, great refresher course!!
+Hilario of GLOATY GLOATSVILE ESQUIRE Thanks for the feedback!
@@1AAuto how did you tighten the bolts under the exhaust manifold, thats a big gap in the video which is where I need help that angle guage does not fit there!!!
In the process of doing this right now on my 1997 Chevy K1500 5.7L. Great video. I would not have been able to do this without it. Started out as an MFI upgrade, but why stop there lol. Thanks a ton man.
What is mfi upgrade?

Helpful video but man I was getting depressed hearing the funeral music since my girlfriend just passed from cancer. Tears while I work on my chevy.
In the middle of doing this myself. Definitely wouldn’t be this far in without this video, very great full
Thank you for helping me do a head gasket job. I couldn't have done it as smooth with out this step by step. Only casualty was a sheered exhaust manifold bolt. Thanks dudes!!!

I like how all the connectors come out so easily in this video and or don’t break.
I know, right? My EGR line nut was completely fused to the pipe, so I had to cut it off and buy a new one. $110 for a useless pipe. I feel like the truck in this video has far fewer miles than my 320,000mi K2500. Like, by an order of magnitude.
Here for research on the upcoming job on my beloved '92 DeVille. I know its a 4.9, but can't find any helpful videos on that engine so just watching as many GM V8s as i can and will simply make my own.
I’m doing this job now. The fact this video is greatly detailed, helps out a lot.
+SavageLyfe Thank you very much!
Very professional, wonderful “how to” video for anybody who may have questions on their ability or even as a refresher course.

Great video! Love the "were going on a voyage" music in the background lol
I almost fell asleep because of it lol
I love the music and would be grateful if, whoever reads this in the future, can find a way to figure out the song and reply back here. Thank you!

i can't believe i watched this whole video...i will never have the confidence to do this... fgs, i just learned how to change the rear differential fluid -- my head gasket is't even an issue. but gawdamn, you did a fine job -- had to stop the vid to get a snack
Keep videos coming helping many people save ...$$
Great video, I will be tackling this job tomorrow on my 97 Tahoe

+Jeremiah Hauser Thanks for checking us out!
I didn’t realize how big of a job this was until I got everything apart 😅
Great video! Very detailed for being condensed. I'm doing this currently and I'm on Day 4 which is the cleaning the heads and block, before reassembly.
Good step by step explanation, so many plugs and sensors these days. I did enjoy watching and thanks for sharing.
Awesome video. Hardest part was getting the power steering pulley off.
30:31 XD thank you camera man for straightening that out
how many hours did this job take? that way I can multiply the hours x 3 for me to do it myself.
These are the questions they don't always awnser,2021should be more informative by now
It should take me a day or 2 to do
What is the difference between the right side & left side valve covers? Also I have heard that it's not wise to remove the rocker arm nuts with a air ratchet or cordless ratchet due to damaging the threads. Also when loosing & removing the head bolts, your suppose to start in the middle and work your way out, right? That's what I have always been taught.
Oh and as everyone else has mentioned, Great Video! and really great job actually capturing the work with the correct camera angle!
Great video thank you. It'b been immensely helpful. 1 question, I only removed one head to fix one cylinder valve and I set cylinder 1 to TDC before removing the head as instructed in the video. When replacing the push rods and rocker arms why do you need to adjust certain ones then rotate the engine to finish the rest? Why can you not just install and adjust them as is given they are already in the same position you removed them?
Due to the cam moving and opening and closing different valves at different times,if you trying to adjust them all on tdc and try to start it,youll most likely damage the cam lifters and pushrods,and it wont start
When painting the heads the color looks better and pops more if you do a primer coat first. And cleaning the heads with break cleaner and a nylon bristled brush connected to a drill will make cleaning it a lot easier and a lot less time consuming!
I understand this video assumes he is teaching back yard/ driveway mechanics but I would think on getting your local shop or dealer that has a sk tank and let the heads sit a day or two Pricing as apposed to pricing on cans of cleaner and towels. A good cold acid dip will disolve all that grit and build up and heads will come out looking new.
At the end you see the time lapse video and during it the valve springs were removed. That would’ve been nice to incorporate during the video. Nice work however. I learned everything but the valve spring removal.
absolute best video I have ever seen
+Shawn Campbell Thank you, glad you liked it! 1aauto.com
Should use old plugs when painting heads to plug holes instead of tape or paper. It's more accurate, and prevents paint from contacting the threads in the spark plug hole or creating a ridge around the edge of the taper.
Cheers!
+R1nger Thanks for the tip!
Whatever camera you used was great. Image was crystal clear.
Thanks for the great feedback! +flyzone100
Perfect step by step video, thank you. I just paid $650 to have my intake manifold gasket replaced, but I think my head casket was the one leaking. Passenger side 😖 I think someone forgot to really check the leak and pressure test it.
They forgot and you paid them to do the job
you did not show how to set timing. but thank you for the most complete video on how to do this.
The vortex 5.7 engine doesnt need manual tuning. It will self tune itself after it's running. It's not like the old 350s. Now those require manual time tuning
Here's how if you havent found out by now and this will work without a timing light, 1.Take the cap off of distributor 2.set distributor into hole make sure rotor is pointing towards farthest cylinder to the front on ur right and if it does not fully seat slowly turn the crank pulley until it drops in making sure rotor stays then if it does not go in look inside where the Dist. Goes with a flat head screwdriver and move the oil thing I forgot what is called but make sure to align it where it drops down with the rotor towards the cylinder I said and if it doesnt start turn the crank pulley 360 degrees around then it should be enough to get it started and as its idling move the dist. Left or right to get it better in time all without a timing light and also lookup a chart for the plugs or tape each one labeling it and remove just the ones connected to the engine not the dist. Hope this helps have a good day!
Really informative video! I learned a lot, it's nice to know how to do in depth stuff like this on a vehicle you own, Thanks 1A auto!
Man ,thank you for making these viddies!Save a lot of money just do it yourself!
Pretty please do one for a Chevy 5.3! Millions of people have this engine and would be a huge help!
Thanks for the video and the list at the beginning, there's plenty of stuff I don't have that I need, so I guess I'll put everything back together for now since my trucks just sitting outside, and ill get what I need for tools on payday next week, have a good day!
Thank you for this video! The shop manual I've purchased has a terrible layout and requires me to constantly switch between books. I would like to state for future viewers. The Power Steering Pully install 1:01:30 is not broken on that engine. A simple pully kit will pull it off but not install. The shop manual states that the install requires a special installation tool. J 25033-C.
Doing this tomorrow for my 454 Chevy. Thanks for the video!
Though, mine is carburated
Thank you, Well filmed and descriptive. I was wondering for the fine timing i would assume a timing light then a small twist right or left on the distributor until timing mark is dead center with a smooth idle. Also assuming this procedure can only be done after truck is started?.
Best video on how to remove head gasket. Thank you for making this 👍

22:35 Peter Piper picked a peck of pickled power steering pump pulley pullers...
I can not thank you enough for taking the time to make this video. I just finished the job on my 305. You answered questions I didn't even know I had, and explained things very well. It was a lot of work but I learned so much along the way that doing it myself was well worth the effort. Could not have done it without such and educational video, however. Or, least, it would have taken me MANY times longer.
I’m about to be doing it on my 305 as well
Do the pushrods still need to spin at all? I’ve heard that they need to spin but with resistance but also he never mentioned in this video if they need to or not
I appreciate this video, Complete instructions. The best I found on you tube so far!

Best and easiest video to follow thanks for all the details
Best damn instructional video I've ever seen. Great job.
Thanks a lot! Very detailed tutorial! I hope I'll never have to do this on mine, but if I do I know how to get prepared properly.
The best video on you tube. Very consistent and clarified. I am impressed
Dang, you guys make some great informational videos!
+Charles Warren Thank you! We are happy we could help.
Take a shot everytime he says, "set that off to the side", then pfau someone else to do it while you watch lol
Does the pressure really matter when tightening everything back
Btw great video thanks. One question. Is that a mortuary next door or is that your music preference?
Everywhere else I'm seeing 180 degrees, not 360 degrees when adjusting the valves after lash is removed.
Is that rough on the camshaft?
Good question. I too, have only seen 1/2 turn (180*).
Thank you for the good video. You did a good job Amigo.
This guy is a fn genius
So you can rotate the engine while the distributor is out as long as its back to tdc compression when you reinstall it?
A1 makes some of the best detailed videos thank you. One question, do you really need to remove the distributor for this job? Seems the heads will come off without it's removal or is it truly in the way? I wonder the same about some of the other items, or if some of these are just removed for clearance convenience.

I just did the job in my '98 K2500 (well, in the middle of it, truth be told) and while I took the intake manifold off to clean it up & replace gaskets, I *think* it's theoretically possible to keep the intake manifold on and only remove a head. To answer the question I had at first myself: the distributor goes *through* the intake manifold entirely, so you can't get that off without pulling the distributor out and worrying about re-aligning this ridiculous, antiquated "timing" system.
It wouldn't be easy to pull a head by itself; remember to remove the intake manifold bolts on that side because they go through the head, you have to have some concern about lining up the intake gasket stuck to the side of the head at the same time as lining it up on a new head gasket, and also I'd worry about the liquid gasket staying sealed in place. But, if I ever do my other head (only did passenger side this time), I'll probably attempt this.
I've honestly never done much of any work on any big engine (usually 50cc to 250cc) and over the past 3 days I've spent close to 32 hours working on it off and on and still don't have it completely done yet, I've got pretty much eveything put back together just gotta hook up some small stuff and then see if it'll start
I replaced timmiing chain but low commpression? Could it be something bent or broken in manifold? Gracias
Great video, especially the camera work and narration.
+Dante G Thanks for checking us out. 1aauto.com
Great job on the video and all the work.
I need to find out how to do this on my 73 dodge van with a 318
Great video just wondering how long did it take you to do all that
After adjusting lifters step by step I still have some jiggle in some lifters is this normal after rotating crankshaft
So my 98 GMC vortec had creamy oil one morning (almost a year ago) I drained the oil and she's just been sitting. I've scrimpd I've starved myself. I even quit cigarettes and finally saved enough $$$ I am gettting ready to restore/rebuild my late fathers truck! Starting with the entire engine overhaul and all of whatever else needs to be replaced. Including but not limited to pistons maybe upgrade cam and shaft oil pump water pump upgraded alternator and starter all gaskets. Now with all that and the inspiration of this and many other videos. Is there any tips you guys might have on required replacement of parts like those head bolts. Also the not so obvious things once the engine is all apart if it's too bad for rebuild and/or needs machining? Thanks great video guys. Also If you haven't heard of stacey david's gearz check him out too awesome projects he's got goin on
Buy one from oreily or autosone . Less headaches
Do I have to set TDC if I'm removing the intake manifold and both heads, but not removing the distributor? Great video. Thank you.
You can't remove the intake manifold without removing the distributor - it literally goes *through* the intake manifold. I thought this at first, but no, they wouldn't design anything that intelligently.
Wow great job ! You sure know engines ! Excelent!
Does power steering pully and bracket have to be removed in order to do the heads
I would like to know that as well
After getting dirt and debris out of cylinder after scraping surface with razor a Shop-Vac with long hose should do I assume also or maybe one placed in hole cylinder during process of scraping
I was wondering why u need to use new head bolts, when replacing the heads? do the old ones weaken under the heat ? why cant old bolts be used? Thanks!
They're torque to spec, the threads won't hold the same torque after the first time
Spectacular video on the subject. Where do you find torque specs and sequences?
How many billable hours was this?
Cyl 6 is filling up with antifreeze and i bought some stop leak but after watching this it doesnt look too bad. I have a 1990 tbi motor so it has even less crap in the way then this engine, only thing I’m dreading is a cracked or warped head, motor has 240k but runs great so might just fix the head gasket properly
+JOE FPOC Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c

I recommend "lint free" rags for wiping the machined surfaces on the block and on the heads.
I purchased mine from Advanced® auto parts.
Can I clean the piston tops too? Or should I leave them alone?
They obviously don't live in the rust belt. 4 broken exhaust manifold bolts later you call the scrap yard n tell em to come get it.
so, when you torque down the heads, you only make one pass at 22 ft lbs. and proceed to finish torque sequence with angle gauge? Also do you still follow the torque order with the angle gauge?
Wow, that's alot of work. Great video! Sooo maybe it's just better and cheaper to do a rough overhaul of the engine?
I have to replace my cylinder heads and this really helped.
+Sarah Gilmore Thanks for the tip!
I removed the valve cover from the engine to replace the gasket, cleaned that cover, but not sure, should I lubricate it before I put it back on the engine cylinder head. If I need to lubricate it should I use something like W-40 or that particular oil, that is used for that car. Thank you for the very useful film, though I personally watch it just to know more about different parts.
Great Job. Easy to Follow, explaining Well! Thanks!
Uhh.. hey you messed me up though man.. 47:38 you pointed at the wrong valves! The front ones are exhaust, the rear valve on cylinders 1&2 are Intake. I totally went through the whole thing wrong lol.. but this video is awesome man thank you so much for it! Great clear explanations and you didn't risk through. Much appreciated brotha. Have a good one!
+D On the Beat Thanks for the tip! We'll pass this info along to our production team.
Once you have the heads back on and torqued,and the distibuter back in its hole,would it be a good time to change out the water pump before you install the the intake manifold?
Very good explanation, I learn something.
I replaced a head gasket on a 4 cylinder and didn’t have to remove the push rods and rocker arms. Can I still get this done without removing them on the 5.7?
Did you have to move them on 5.7?
In the process of doing my 96 Silverado 305. I hope I get it right.
+E J best of luck to you on your repair!
Did you have to remove the push rods?
I found that the pushrods are just short enough to fit into sandwich bags. I just label a sandwich bag for each rocker assembly and separate them that way
Thanks for the feedback! +Anon Ymus
for the new head bolts, is it a must or a preference? im doing a head gasket soon and i just want to know if its necessary or not for budget reasons, and may i re use the old distributor?
I really appreciate your help..
Do you spend any time cleaning the tops of the pistons? Is it worthwhile to do this? Seafoam? Of is there some other kind of spray on cleaner to loosen the carbon deposits on the tops of the pistons?
