I'm a 40 year old single momma and I've had to do this job and others myself. This video walked me all the way through, start to finish. I appreciate these videos sincerely. Thanks for making this possible.
Gonna give you props. One of the hardest valve cover jobs I’ve done myself
Thank you so much! This is my very soon project and one I now dread LOL. Makes me miss my teen years in the late 60 and early 70s, Those valve cover gaskets were a 30 min job.
Video is so fantastic that this girl got it done!! Couple notes.. buy a little hose on the intake and just cut the old out if the way.. it breaks anyway. Second, firewall bolt no problem is a Mini ratchet, short extension and regular 10mm socket… the trick for me was to step on a stool to get over the top comfortable enough to get to it 👍 no worries following this video. Thank you soooo much!’
This video just saved me $600! Just a do-it-yourselfer here, shop quoted for 6 hrs, I did in in 6 with the help of this video. Took me almost 2 hours just to get the 10 bolts off the intake manifold, lol.
Same instruction can work for Yukon XL. Just a few more AC parts and such. You fixed my truck! This is one of the BEST mechanic videos on TH-cam. PERIOD. Simple quick no bullshit. I just watched a few times while having some drinks and repaired my truck. F**** the center bolt on the intake though~!
Really appreciate your video. Hardest part for me was the manifold bolts, bottom alternator bolt, and bracket removal attached to the manifold. I didn’t even know there was a bolt behind the hose on the manifold till I rewinded your video. Million thanks
12 minutes in the video took me 2 hours but I’m almost there !
2 hours don't seem bad. I gotta do this today so if you took 2 hours I'm looking about 3.5-4 hours which still ain't that bad. Hopefully I can do it
What r u slow poke Majoe. My 5 year old grandson did my valve gasket in 30 minutes. He stood on a step stool and I had to break loose several bolts because he is just not strong enough yet at 5. Do you need help breaking loose bolts too?
At one point I said out loud, "I love this guy." Thank you for this video, without it, I'd either take my Trailblazer to a shop ($$$) or struggle even harder to get this done. Thanks again. Liked and subscribed
This blows my mind, years ago, my inlaws had a trailblazer and it needed this job done, i looked at it and after trying for a while to figure out how to do this, i gave up and told them sorry, you have to take it in, what blows my mind, is that people think this is ok, this is the kind of crap i have seen time and time again from GM, getting a intake manifold and valve cover gasket off shouldn't be this hard, this is stupid! For all you GM lovers out there, have fun with stuff like this, but for me, its sayonara!
Dude. Best video on working on the top end of the 4.2 Chevy i6 block awesome job
Your instructions made me feel comfortable doing the job myself after paying someone to do the job and my valve covers are still leaking. I like all your detailed instructions. I keep this video right by my side because I had to refer to it constantly.
This video is the definition of helpful. Its really detailed, saved me a lot of money. Great stuff!
Fantastic video, very helpful. A few things I found:
1)don't fear that rear-most bolt. If you sort of lay on top of the motor you can feel it with your left hand and easily guide a 1/4" drive socket on a swivel onto it with just a ~3" extension. I thought this bolt would be a nightmare and it was actually very easy
2)the studs for the PCM come out with a 4mm socket, but use caution. I preferred having those studs gone when removing and installing the intake manifold
3)the hose that obscures the "hidden" bolt in the center of the manifold can be removed on the bench (or perhaps in the vehicle) if you heat it with a heat gun. I did this on the bench (also needed to retrieve my socket that had become trapped LOL) and just disconnected the bottom, making installation MUCH easier. The hose slid back into place by hand easily, although I used some WD40 to increase my odds of sliding it back into place with no drama
Probably the best DIY video on TH-cam. Great job, thank you. Hope to sell mine before I ever have to go through this, 😆.
Just by starting off your very detailed. Thanks for taking the time for all of us. I'm getting the courage to do it myself and save me 800$
Thanks, very good video. No too much videos about this gasker replace. It was very informative.
Thanks for a great video, you saved lot of time for me. Had some oil in the fifth plug hole when I serviced my 02 Bravada, and now three month later I have a fifth cylinder misfire. Thumbs up!
Nice job buddy, you make it look so easy, and your instructions are so clear. Thank you.
Just used this how-to and it took me about 1 1/2 hours to get this removed. Still waiting on the parts to get in just wanted to get a jump on this. Thanks for the great detailed how-to.
Great instructions, now I will allow a couple of days to get it done.
Great video! Thank you for also pointing out the torque values and going through the reassembly as well!!!
I’ve done plenty of valve covers gaskets on many vehicles and this is my first time doing it on a trailblazer. This is one of the toughest ones I’ve done. Getting every gasket replaced while I am in there
I like how you break the tutorial part down for us new mechanics gratitude 🙏🏾
NOTE: for some models (or all, I'm not sure), there is a couple of wires that go all the way down the passenger side of the motor, and back to the front diff actuator. It took me about 10 mins to find it. Only accessible from the bottom of the truck as its on the back side of the oil pan. I didn't see that in this video, so I thought I'd just make a note of it. 😊 thanks for the video buddy. I used this as I was doing the job. Very helpful
Thanks for adding that. I’ve had a coupe with that now that you mention it(forgot to say something in the video). Thanks
I watched this video some time ago and now I finally get to do this job. Oh boy I can't wait but thank goodness for this amazing video or I would be lost. Thank you very much and wish me luck!
This is a huge help. Thank you for making this video.
This video was very well done. Not a lot of them on TH-cam so I'm lucky you did this on one of my cars, lol. Anyways thanks, man.
Awesome video this does nothing without explaining what his doing..thank you for a great lesson.
15:00 That stiff hose is part of the PCV system. It can be a real pain to remove! There is a spring clamp, like the OEM radiator hose clamps but smaller, on the end of the hose next to that 10mm bolt. It's bonded to the hose. What I did was use a small pair of needle nose locking pliers and open up that clamp. Then the short end of the hose can be pulled off, and the long end will come right off the intake manifold. Remove that spring clamp from the hose and just use a small worm drive hose clamp. Makes removal much easier next time! You can see that clamp at 16:55.
Very good video. Great step by step directions.
Man I’m replacing my valve cover gasket and I was coming from the drive wheel well and I was fighting for like a hour and i decided to look for a video and I found urs thanks a lot
Glad it helped!
Doing this tomorrow. Very helpful.
Excellent presentation Sir!
Thank you for the video it is really helpful, you make it look so easy. Nice and clean job.
Thank you for this video it was huge help
I will do it with this instructions, Thanks a lot the best video. I'm from Mexico I send you greetings.
Great detailed video. 30 minutes well spent
I bought my 2005 Trailblazer last year & I just changed the sparkplugs today. Even though it was running smoothly, I just changed the oil & air filter yesterday & I was just gonna change the plugs outta GP so I can see what's going on in there! I had three plugs that were a little wet around the sides but none on the electrodes ( Iridium's) but they were the original plugs & I bought it at 124,000 & I'm at 133,000 now. The plugs were the original plugs that came from the factory because the part numbers were old & they were worn but not done which is a very good thing considering the age! A little old man up in Canton Georgia had it & garage kept & she looks good! Clean with no rust! The coils were all dry but I figure to be doing this job pretty soon 😭 Thanks for the video & now I know what to do unless I pay my mechanic & I'll sit in the lounge watching TV 😁
Wow, great video! It is ridiculous to go through so much work for valve cover gaskets, though! Tx so much
Thanks for the video, I watched another video and the guy was taking extra stuff off that you don't need to and was not very explainable. Came across your video and now I know what I'm doing when I get ready to do my daughters trailblazer.
Fantastic video.
You have been a great help Thank you
This video save me a lot of money but gave me a headache because it was my first time doing this. After my dad told me the engine coils were oily, we knew it was going to cost a lot.
Yea I can't wait to start this job lol I didn't know what I got myself into
Excelent vídeo. Thank you for showing.✔️✔️✔️
Everyone is tasking the same job around the same time 🤣 a little fishy, but I am tackling this tomorrow and the day after wish me luck!
I'm guessing so. Lol. You got this!! One step at a time!
@@DMoneyGarage my lord I couldn’t even read what I had said lol. But thank you! Doing it right now
Shit I just discovered my leak too right at about 215k 🤣
I loved it, I think I can do myself now.
Damn thank you so much for showing me where the long green plug went on the on the passenger side by the oil filter! Try to figure it out for hours now
Bro, this has got to be the best video out there, and if you are doing all your videos like this, your channel will SKYROCKET!!! We are doing this job soon, and this video was PERFECT!! Definitely subscribing!!!!! By the way, my name is Tim! By the way, those few thumbs down you have must be from people who have NO IDEA how to work on cars!
Thank you!!!
Love this video! Great job! It walked me threw mine that i am doing now. ONLY issue is you don't torque them to 89ft lbs they are supposed to torque to 18 ft lbs. But my issue is my bolts keep snapping before i even get to 18dt lbs! Any help js much appreciated.
Any idea why my trail blazer would start rough and idle rough but then clear up and run decent after doin this job. All my wires are hooked back up. Every time i crank it over it starts really hard and still have a miss fire. Any ideas. Ill probably pull it all back aprt tomorrow. Thanks
Excelenrt. Video berry berry god! Thanks!
Thank you!!!
Would I have to replace the spark plugs even if they’re a couple months old? Along with the coils ?
I literally just had my valve cover gasket blow like 20 mins ago took off the entire intake at my girls apartment took the whole thing apart dried the seals and re lubed em and reinstalled fixed the issue
Hi, good job?
Question?
So for the trailblazer 2002 ext are those smaller sizes gasket for each coil right? Is not like the other models biger long gasket for the valve cover gasket?
For this car those valve cocer gasket are diferent right? No need silicone? For extra safety ?
I got one valve cover gasket the oil are starting to leak all around in the passanger side is getting wet there.
So i am triying to do this car sooner this weekend may be.
Thank you !!!
Great job. I have cuestion I have trailblazer 2005 and oil is Goin to water . N water Goin to oil you think is intake gasket or head gasket??
I just did this for my neighbor, we did intake manifold gaskets too cuz why not. But that bolt against the firewall I used a 10mm deep with a 3/8 ratchet and no extension. Then I put a steel rod on the handle and tapped it down with a mallet to break the bolt free and then spun it off.
Nice. Definitely other ways to get it. Lol. I'll try that on the next one. Thanks.
@@DMoneyGarage thank you for the video though, I knew where all the bolts were before taking anything off and that makes the job much smoother
That it does. Thanks!
thanks for this video trailvoy needs help BAD!
I’ve got a 2 pin connector right next to the fuel rail just hanging after putting everything back together I’m not sure where it goes…. Any idea?
Hello..where did you get the pump to suck the oil from the spark plugs?
Is the same Gasquet. Of the water. Go inside of the oil engine? I need change the gasquet my truck is over hot over 20 minutes driving. 😢. I need fixing
Thanks boss. Phew this is labor intensive…
I finally did my TB ... ran good for a day now I'm getting p0030 and misfires on cylinder 2 and 3... going to have to do some testing this weekend
Check your plugs and see if any oil made it in any of the packs
@@danielromo2110 I did ... they are clean. I replaced all the gaskets on the valve cover. I'm about to swap out the ignition coil to see if the coils need replacing.
@@danielromo2110 I also replaced all the plugs
What tools do you use to remove the hoses?
I found it was easier using a nut driver on most of the intake bolts. Still struggled with the last bolt. But wasn't too bad.
Wow this is genius.
you are amazing
thanks a lot man
You are welcome!
@@DMoneyGarage
😍😍😍😍😍
Thanks for sharing your awesome video! I have an 04 GMC envoy your Blazer is a clone of my engine! ? Also 🤔 can a leaky spark plug tube gasket and or valve cover gasket cause oil to deep in the cam shaft Senser solenoid as well? Also I'm replacing map sensor and cam positioning sensor as well. Thanks again Sir "D money🚙💨💨💨💨💨
Not deep seep
Might as well do my motor mounts and intake gaskets too
I just did the Moter mounts and still turned out to be a pain
About to so mine too
I can't find out where one of the wires goes back to. It's coming off in-between the 2 and 3 coil wire with purpol connector
nice
May as well give the throttle valve/body a good washing while it is there in your hands.
It got a new one the next day. Figured I’d do the valve cover gasket then swap the body the next day. Lol
Yea this was not fun to do at home, but it’s done!
find the leaky one then suck what you can out with rags, clean with brake cleaner, then use permatex black rtv "right stuff" around where the plastic and aluminum meet... put back together. did this years ago
Hey man quick question. When taking the intake manifold bolts out do they come all the way out? Mine come basically all the way out then stop and they can wiggle around and I can keep on loosening them and they just spin as easy as the air blows.
They stay with the intake. They are captured. They can be pulled out but don’t need to be. If the intake has been off before I’ve seen them not stay in the intake. Hope this answers your question.
@@DMoneyGarage ty man I was getting frustrated. I was like what type of f’ing bolt just keeps on spinning but won’t come out. A cold natty light was keeping me cool headed though in the process😂 .. thanks again! Have a good one.
What area are you in? I need this done.
One more question. I finally have all the bolts loose on the manifold. It will not budge. Is this due to a gasket being stuck on good?
I’ve had to give it a good tap going towards the drivers side. They are rubber oring style seals so they have a tendency to get stuck. Make sure you got all the bolts first. Intakes aren’t cheap!
Amazing video! I have to do mine due to misfire and oil in the spark plugs. I know mine will not go as smooth as you made it look. Wish me luck!!!
You got this!!! If you believe you can do it then you can do it!! Let me know when you get it done!!!
I followed your video step by step pausing in between your instructions. Worked out amazing. Thank you for the tips on the 2 hardest bolts holding on the intake. Saved me a ton of time. Thanks again for posting this video. You saved me $625.00 which was quoted to me from my local auto shop. Thanks again.
Glad you got it done and everything worked out. Thats why I post the videos😁
I have the same issue on my 05 Trailblazer. just need to find the time now.
Why does mine look like it has 2 fuel lines right there where yours had one? 2003 Envoy.
Do I disconnect both?
Yours could have 2. They used to have feed and return fuel lines and in 04 or 05 they went to only a feed line and pressure was regulated in the pump.
@@DMoneyGarage ok thanks. So I should be good to disconnect both like you did the 1?
Sure thing.
whats the little hose called i tried to move it out the way and it broke :*)
Did you also replace the air intake manifold gasket too ?
Yes. All seals and gaskets were replaced.
How do you remove the fuel line without that tool? Also, i have two fuel like lines right there
I no one day minds will need changed as well because I just changed the plugs and seen a lil dryed up oil so do you think I might need to change minds to because I'm having a misfire on four but didn't see any oil on the cores packs so what you think I should do and great video by the way because I'm like it probably want be hard taken everything off my problem probably will be putting everything back on it but I'm sure it's gone save a lot of money.
If there is no oil in the hole, swap the coil with another cylinder and see if the misfire moves. Those coils go bad frequently also.
Ok thanks
How did you torque the back bolt against the firewall?
Honestly the easiest way is the use the setup that you are using on the rear bolt and feel how tight another bolt is and then tighten the rear one to feel. I have a 1/4 inch torque wrench but its still a bear to torque it.
89 in-#; 10 Nm.
This is a very good video. I need to replace the valve cover gaskets BUT it looks like a lot of work & that bolt by the firewall is going to be the hardest thing to do. I'm just not sure I have what it takes to get this job done.
I hear you … this looks like a weeks worth of a project. Working full time and doing this might be killer. Pushing 235k miles on mine.
@@TheCodesterr well with everything I did, it took me roughly 6 hours. I'm not mechanic but pretty handy. This video did help tremendously.
@@JackMoveShawty oh nice that seems really quick! I would say I’m handy too, but would really take my time on it to make sure the intake didn’t break or anything. So you ended up replacing it and everything is working now??
@@TheCodesterr yes I replaced the valve cover gasket & the spark plug rings (I guess that's what it's called) & everything is working great. One thing I did mess up on was torque when righting the valve cover screws. I don't have a torque wrench, I was just using my ratchet set & over tighten one of the screw & broke it off inside the hole. Now I have to spend time one day to get that stem extracted out & replace that screw. But even with breaking that screw, everything is working great. No leaks because I guess the rest of the screws were so snug it mad a complete seal. I have no real complaints.
@@JackMoveShawty phew, thankfully that sealed it up for you!! Ive been reading it’s common for the bolts to snap on the intake manifold… did you have any issues with that?
just did this yesterday after vid, what a pain in the ass!! but I cleaned so called unserviceable pcv valve. no more leaking oil and oil pressure doesn't jump 20psi anymore, pcv, intake bolts were the worst part.. rest was ok
did valve cover gasket too. it and gaskets around plugs were dry af. crumbled when pulling out valve cover...
also only has 1 clean plug "hole" oil was seeping in all others.. wish I could show pic
that bracket you are removing at 3:56 is a USELESS bracket, I removed it to do something years ago and NEVER reinstalled it. Also I highly advise the use of a Ratcheting Wrench for removal of the lower Alternator Bolts.
I do not like removing that air intake 😅😅😅 man o man
I feel stupid but i can't find where to harnesses connect. Attached to the blue harness into the computer is a purple harness right before also right by the alternator on the harness that goes over the engine also near the computer is a small white harness... I know it aint much but i fr can't find where it goes..
Thanks for the video but in my opinion u took off way too much for just a simple gasket change. I only took off the computer..loosen top 2 bolts to alternator sliding it forward..that let me access to first air intake manifold bolt..the one in the back I used multiple ext...about 2ft If u have them like me...and went thru the wheel are for the far right intake bolt in the back by the heater hoses slid the whole unit to the left a lil and presto I can access the left side of the valve cover...all due to your direction though. God bless all and good luck 🙏
just out of curiosity, how many miles were on the car and what oil and oil change interval (miles) were you using?
160k and after I started doing the maintenance for her I did every 4-5k with full synthetic
@@DMoneyGarage 5w 20?
I just did this to my 03 trailblazer. I followed the steps you laid out. Very good video, It helped immensely. I thought I had followed the instructions perfectly, but when I went to start my trailblazer it turned over then stalled out immediately. When I tried to start it again it wouldn't start just the rapid clicking noise. I checked the fuses, & the PCM fuse had burned out "it wasn't burned out before. So I replaced that & now when I try to start it It just chugs for a little while Like it wants to start, but it not able to fully kick on. Can you think of anything I may have done wrong while making the repair that could cause this? Oh I originally changed the gaskets because my trailblazer started misfiring on cylinder 1, & I found a very small amount of oil in the cylinder.If you get a chance to respond I thank you. Again great video.
Maybe forgot to re connect a hoes or connect a sensor, my guess.
Did you found out what was the problem same issue here with my trailblazer?
@@JoseDiaz-rm7rydid you figure out the issue ?
Can this be causing rough idle and smoke coming out of the oil fill
Rough idle yes. Smoke from oil fill no
I have white smoke coming out of the oil fill and I have oil in spark plugs in changing the valve gasket s but wondering what the white smoke could be
I just did a oil and filter change two weeks ago also put on a brand new radiator vvt seloniod also don't know why there's smoke coming out of oil cap almost instantly
I have a 2003 Chevrolet trailblazer and the inside of the truck always smells like fuel there's no smoke. I not sure if it's gas or oil, but our clothes always smells. Can anybody tell me what could it be? Could it be the valve cover gasket or something else? Its a really good truck. It's just the smell. Any help greatly appreciated.
Nice job on replacing gasket, looking at the throttle body, would have taken it off while ur there to clean it, looked pretty nasty
It got replaced on a later repair due to dtc’s. Customer wanted the misfires fixed first. Customer didn’t have the money for the throttle body during this repair.
my mechanic said you dont have to take all that off. just move the pcm out the way.
Sure can. But I don't mind spending the extra 5 minutes to make more room🤷♂️.
they cam pos sensor connector is always tight on these trailblazers
Its about 50/50 for me. I always try against my better judgment 🤷♂️lol
Do you think this is worth replacing on an 07 with 235k miles? No misfires on mine.. just a slow leak … not sure if it’s coming from coil packs and/or valve gasket. I replaced the spark plugs and if I remember correctly it wasn’t flooded with oil.. but could be wrong.
Well… I did it and wow!!! What a job
@@TheCodesterr how bad was it? Is the truck still running
@@fuckcensorship69 oh man this was def a doozy. I took my time, but a couple days plus an all nighter I accomplished it. No leaks through the coil packs now. Glad I did it though. I say go for it if you’re not needing a vehicle for a few days. It wasn’t hard, just gotta work a few bolts here and there and be patient. The intake was the hardest part. Def need the right tools
Hello,
I have a very clean 2005 Envoy 144k. Simply replaced the plugs, easy.
I stumbled on your video, omg what a mess. So is this an inevitable problem that I'm going to have to deal with some day? When removing coil #3, I noticed just a tiny bit of oil where the cover meets the head. Nothing like what you have here....not even close. Thanks Tom
Eventually you'll have to but hopefully not for a while. Lol
great vid, there 4 a while those crickets just had to get their 15mins of fame, and rude always trying to over talk u 🤣🤣
