Great video.
First thing I do when I get a 3800 is this. As common to me as changing the oil on these cars lol.
I always change the crap plastic intake to the aluminum for the swap.
Good idea
@@SalemDoyle well when its are own cars lol.
Shocked you do not have more subscribers then you do.
Videos are informative and you reply to questions.
Hell I know how to do all this stuff and I still watch and learn from time to time.
Any one who say they do not learn anything every day is lieing to them self's
I wish i had more, but honestly, still surprised i have as many as i do. Thank you.
@@SalemDoyle you him get there
Where are you getting an aluminum intake? Dorman’s replacement parts are all plastic like oe.
This is the best tutorial on this job by far! Most people don’t go step by step like this, they’ll just do a large portion of the job then check back in and say what they did. GREAT JOB!
Thanks
Does the plastic intake not have the tube running inside it? I was scratching my head trying to figure out what it was when I removed the metal one. It was just sitting there when I removed the cover. I guess it is to keep oil from getting out the vacuum port by giving it a long travel to the outside.
This tutorial was my saving grace and saved me almost 2,000$ I truly do appreciate you helping complete strangers like myself!
Awesome, glad it helped
You made this job very easy to understand and took the time to explain how to put it back together instead of the " do everything in reverse" that some people like to say. Thank you
One of the best car repair videos I have watched. You deserve more views and more subs. If you dedicated your career to teaching automotive repair you would do very well at it.
Thank you. I appreciate that 🙏
Man, this made it way more simple than i had previously thought. Thx for the tip on the aluminum elbows. Great video, very simplistic. Be safe.
Glad it helped
After watching this vid back in September 2022, I did the work myself the following month in October. Took me 3 days cause of life, but I got all the work done step by step. Lots of work, but worth it. Got the aluminum felpro gaskets. Replaced some parts while I was in there. I did somehow pinch that right gasket and it started leaking, so had to take the lower intake off and get it seated correctly. After that though, I've driven both a 600 mile round trip and a 400 mile round trip successfully. I've probably saved like $1000 in labor cost. I've driven 3k-5k since, no leaks. Engines just been purring along
Nice work
I just want to express my gratitude to you for your CZcams video "Buick 3800 Lower Intake and Valve Cover Gaskets". Previously, the extent of my car mechanics has been to replace/service my own brakes, engine oil changes, ATF changes etc. Replacing the lower and upper intake gaskets on my friend's Buick Lesabre is the 'biggest' job I've completed to date and your CZcams video was my constant companion and mentor throughout the job. Just wanted you to know that I appreciate you sharing your knowledge and talent in this way!
Thank you. That means a lot. Glad it helped
You’re outstanding brother. No wasting time is my fave. Wish everybody cut out the fluff and was thorough like you. Thanks!!!!🎉
Thank you
My 2000 Bonnie blew the lower intake gasket two days ago :( This video will make the repair so much easier. Thank you for posting. It is very much appreciated.
Glad it helps
This is THE BEST walkthrough for this engine! Thanks to you, I found the final two bolts to take off the lower intake. So happy I didn’t just brute force it with a pry bar. 😅
You are brilliant. I have one of these vehicles a 2005 LeSabre and will have to check for any oil leaks on or around the valve covers. Great video. THUMBS UP!!!
Very well done!!! Thanks, I start on mine in the morning and will be referencing this vid!
How did it go??
Thank you for the very detailed video. Only been able to work a few hours a day - I'm not a mechanic, but mechanically inclined. Almost done with the job. I inherited a 32k miles 1997 LeSabre and hope to bring everything up to par, so I can take it on long trips without any surprise breakdowns.
Looks like you do work out of your garage? If so, not any chance you're in Houston?
Nope. In NC
@@SalemDoyle So sad....NC
If only you were near Nashville! Lol
@@SalemDoyle Where in NC? Let's come to da beach and replace gaskets on my 2007 GP........16 YRS and counting! Yea!!!
I'm cleaning the throttle body ( never ever cleaned and it is Grose) and replacing the MAF today. HAPPY 4TH!
@@denisethompson9203 im pretty close to winston salem. Long way from the beach
One of the best step by step video's.great job.
Thank you
Absolutely agree
@@SalemDoyle thank you!
thank you. doing this job at the shop right now. got it all torn down today now in the cleaning phase so I can put it back together in the morning. I took the tb and upper plenum as a unit other than that looks like I'm right on track.
Nice
Cleaner product suggestion..gels?
It took me longer than 17 minutes, but the video walked me through all the steps and I was able to do it all by myself. I feel pretty good about it. And the car feels good about it too. Thanks!
Thank you for the video. Thanks in part to it, I was able to successfully change the lower and upper intake and valve cover gaskets. I appreciate your time and instruction!!
Awesome
I did this to mine in 2013 once someone finally posted a decent video on it. Once your familiar with the top end it's not too bad. I used the plastic elbows though and I think it's leaking now. I'm on my 3rd set of parts for so many things on the Regal lol..
Your tear down and repair is so helpful and will save my daughter $1500.00 in repair while providing guidance for me to do the job. Again, thank you for the video.
Charge her anyway. She'll just spend it on bubblegum and pokemon games. I think thats how kids work nowadays.
Great video! Excellent description of how to do this job.
My son and I followed your instruction and did this on a 2000 Buick Regal with the 3800 engine.
There were only a few differences between it and the car you worked on. Most obviously was the Regal has upper engine mounts between the engine and radiator crosss mount. Of which, we only had to remove the one on the passenger side to accomplish this task.
The other big difference we found was that the throttlebody on the Regal has a support brace that goes between the lower intake and the front lower part of the throttlebody. We found it very difficult to access the bolt attaching it to the intake because the exhaust crossover passes too close to it and the heatshield prevents access to the lower throttlebody bolts. So we disconnect the brace from the throttlebody and left it attached to the upper (plastic) intake while pulling it. Then, we separated the two because we could easily rotate the whole thing and access all the attaching hardware.
The rest of the job is pretty much the same.
Thanks for the great instructional video!
Awesome, im glad it helped
Just bought a LeSabre similar to this one and need to do this asap. Great tutorial. Subscribed!!
Thank you
You can explain it very well. I would love to buy such a Buick in the States, but it's kind of too difficult to get a good one from Germany.
Amazing Video !!! 👏 Five Star commentary and instructions… awesome stuff
Thank you
Great video 👍 Didn't have to watch you loosen every bolt! Great way to instruct. I can tell that you know what you're doing!☺️
Thanks
I was able to replace the intake manifold gaskets on my 2002 Grand Prix thanks to this amazing instructional video! Thank you!!!
Awesome
Thanks so much, getting ready to do this on a 2000 Impala, nice to know what I'm getting into!!
Yeah, its not a bad job. Way easier than some engines
I don’t own one of these cars but am looking for a clean, well-maintained ‘05 LeSabre or Park Avenue as a daily driver. I could go buy a new Buick today, but none can match the ride quality of these older cars. And after 27 years in military helos I need something that is easy on the back and rides smoooooth. I do most of my own wrenching, and videos like this are a valuable tool to have when the socket hits the nut. (Ouch, that sounds painful!) Thanks for the great tutorial, liked and subbed! 👍
Awesome. Thank you
Awesome video Salem Doyle. Thank you very much.
yah jest feel the " secret " bolts ,take out and oil will drain . got mine apart now , still cleaning
I was thought that would be awesome to do with one of those. Awesome job
Thank yoooouuuu so much! This video is about to help me out big time ❤
Same. My car overheats and i'm sick of it. Bout to fix that.
WHEN PUTTING ALTERNATOR BRACKET BACK ON MAKE SURE U DON'T PUT TOO LONG OF A BOLT INTO THE TOP OF VALVE COVER IT WILL PUNCH A NICE HOLE THROUGH THE BACK VALVE COVER! That sux!
Lol I have done that same exact thing once a long time ago
ALLLLLLLLCAAAAAAPPPPPPPSSSSSS
Great video man.and you explain everything very well.
Thank you
Great vid! Wish I had the space to do the job myself. My neighbors...who are great...but also members of the HOA would have a fit. Lol I can only get away with quick jobs like breaks and alternators.
Great video I think I need this job done now but don't have the money or know how to fix it myself!
I just did my intake and valve cover gaskets today, but having one hour of sleep and heat fatigue made me lose track of some things. This video is the greatest detailed walkthrough of this repair and I will be tearing everything back down and doing it again to make sure it’s correct
Thank you. I hope it goes well for you.
Yessir, I got my game plan ready but now I need to get back uo there to the shop 😂
Great video friend Currently I have this problem with the valve gaskets, I already got the parts to replace but the mechanics I know either have work for several weeks or do not have time to do it, from then on the workshops are not very trustworthy 😅, and I don't have the skill to do it on my own Great tutorial
I have a car chaity and someone gave me a 2001 Buick that leaks!!! Very good video, I have everything on order. Peace to you!!
Definitely should drain the engine oil with the front end raised to get out any antifreeze that likely was spilled in the engine. I have found the longer filter (1036 Napa) fits nicely & provides better filtration, should fill it first
Thank you for this video, so thorough and easy to follow. One question- all the connectors on the fuel rail- are any of them the same as another or do they all only have one match? Just wondering for making sure i get them matched back up properly when re assembling. Thanks
They will mostly only reach the one they go to.
Awesome video man thank you 👍🏼
I will reference your video when I do mine 3.8 I have 2005 buick lesabre. Thank you for the video.
Glad it helped
Great video. Keep up the great work.
Thanks
Excellent video and commentary. I'm getting ready to replace mine and this video is by far the best.. Well done!!!
Thank you
Best car repair channel
Thank you
Great video mate!
Thanks
Great job making this video
Thanks
Awesome video, thanks
Great video! Never done this before but going to attempt it today on a 2006 Buick Lucerne. I will reply to my comment here to give everyone an update on how it went!
Awesome. Hope it goes well.
Massive help man thanks. 👌
bro, you're my hero, now send me a parts cleaner so i can put this thing back together
Lol. Need to get me one first.
How long did it take you to do this job?
thank you for the great video sir
I did this job on my 01 Pontiac Grand Prix GT 7 or 8 years ago. I recently started losing coolant, but I can't find a leak, so I suspect the upper plenum has cracked or warped allowing coolant to leak into the manifold. I'm getting a ZZ Performance plenum for the replacement. In the video, were these the original lower intake gaskets? Great work!
03 impala with p0172 and p0303 has aluminum elbows but the oring must be shot as well as the gaskets under the plenum cuz it is a damn mess. thanks for the vid, gonna use purple power and a hose to clear off all the oil/coolant mix covering the engine
Good stuff, thanks
Great video. What size are the fasteners on the bracket on the back valve cover?
Your a genius, great video
I’ve been chasing this p0305 code for the longest I’ve change spark plugs wires and coils And icm I’ve also change my fuel injectors
Mass airflow sensor fuel pump pcv valve egr valve mass airflow fuel line could it be internal I was thinking 🤔 maybe a broken valve spring
P0305 P0420 and a P0171 code is present but the P0305 need to be fix
That 171 code is an issue too. Have you checked compression?
Love the shameless UHC MS plug. LOL At least using your card keeps you compliant! All things considered, very informative and I'm hoping that I can have this handy because you can't seem to get a Haynes or Chilton manual for my '07 Lucerne CLX.
I will be doing this for my son's 1999 Park Avenue soon. I plan to buy the Felpro set that you mentioned. In that kit there seems to be 2 different sets of strips that lay down on either end and go under the lower manifold. One set is blue and the other brown. Will I use both or just one set of those for his car and will it be obvious which to use? Thanks.
You will only use one set. There are two because they changed over the years. Just use the one that matches
Job well done
4 yrs on... thx man.
Great video. But I have no start after changing the LIM gaskets. Possible moisture in the 6 plugs? Thanks.
Maybe. Look back over your work make sure nothing is unplugged
Excellent video.
I gotta do it. I wish I could hire you! Lol
I noticed you didn't show an inspection of the upper intake. I have found that the area around the egr pipe, is prone to pinholes, cracking and just plain blowing out. Mostly inwards to the plenum. This is one of the major composite plenum failure points.
Yes, dorman makes a replacement
Thanks for the great video. About how long does this all take ?
Couple of hours or maybe 3
Im going to attempt this in a few weeks on my 97 N/A park ave. Do tou have any tips on getting the the elbows that remain in the block out? What would you say time wise for this job for a fairly mechanically inclined home mechanic? I can handle small bocks but never really messed with newer stuff. Great video, and explanation.
I used the included black silicone. One corner leaks oil now
I prefure to use ultra grey
Great video
Thanks
Damn I wish you were in north carolina, I need someone to replace all of the gaskets
Hey thanks for the informative video. Question, do I only need to take off the tensioner when doing the rear valve cover? I'm only doing the intake gaskets
Also, do you recommend any oil additives or coolant flushes after? thanks
Correct, but removing the alternator makes it easier to get one of the bolts
nice explained really well
Thanks
I wish I knew how to do this stuff. I’d drop a bolt down the piston hole or something stupid. I was nervous just watching.
Great video. I noticed it said thread locker. I would have thought thread sealant? Any insight on this? Thank you.
I believe thread locker is what it needs, but locktight makes a sealent/locker that is both
@@SalemDoyle I didn’t know that. I’m trying to do some research now so I have what I need before I get started.
The series I & II engines had the crappy turkey pans, the series III were fixed. My 2005 Lacrosse has just over 311,000 miles on it and nothing inside the motor has ever been touched.
Great Video thanks much,👍
wheew.. ya.. Hopefully all goes well. I paid the mechanic to do that. Even just watching it. Thats above my skill set.
Amazing video man! Do you know what the torque specs are for the upper intake manifold and fuel rails?
89 inch lbs iirc
Upper Intake Manifold:
89" (inch) pounds or about 7.4 (Divide 12/inches = 1 foot into 89") foot pounds.
Snug on fuel rail.
I done this job appr.8 months ago. Smashed the end of the EGR tube flat when I bolted it to the manifold. Not good at all.
So I had the same issue with the plugged hole at your 9:20 mark. A friend mentioned that GM Stop Leak Coolant tabs are required during coolant change. Does anyone know if this is true for a 2000 Lesabre?
Hey Salem, new subscriber. Great video. Do you think oil in the coolant could be caused by the intake gaskets leaking?
Hi, thanks. Its usually the other way around, lower intake leak causes coolant in the oil
If I don't have the tool to precisely measure the torque on some of these then it should be fine to just hand tighten them securely without over tightening them I suppose? Also what kind of cleaner are you using to clean the parts you side aside?
I used a parts washer, but brake clean works really well.
Was going to do this myself then I saw everything involved LoL 😂 definitely going to get someone else to do it
Did you have someone do this of so how much did cost you i was thinking the same thing as you.
@@reaver9833 i never got it done. I just bought a new car instead. I still may do it later on if I don't decide to sell it and I will let u know
@@brandontalley4288 heard thank you for the reply
@@reaver9833 sorry ☹
Should I put oil in it to help flush the crud in the valley into the oil pan before I drain the oil?
You don't have to, but that's not a bad idea
Any tips for the low coolant sensor and coolant sensor on 3.8 SC motors?
thanks in advance. have the low level light on start up and hoping thats'all...
Thank you for the heads-up on the two interior nuts in the Intake Manifold and waiting on draining the oil!
Question: Should both the hardware (Bolts & nuts) and all of the old hoses and clamps (especially the Spring load ones) be changed when doing this replacement?
You dont have to but its not a bad idea
Awesome video, about to do this to my 98 lesabre for the second time. Buliet proof motors, just need extra care with their flaws. Any idea what the torque specs were for the upper intake manifold?
89 in/lbs
Thanks brotha, you really knocked it out of the park on specifics and details. Great energy man. Keep up the righteousness. Gotta keep those 3800s alive. So 89inp, or roughly 7.5 foot lbs?
Yes. And thanks
Are there torq specs for the EGR metal tube that attaches to the lower intake manifold- working on a L67 engine.
Good helpful video
Our 2000 and 2004 Chevy Impalas 3800 both got a recall for possible fire hazard from oil leaks onto exhaust manifold. The dealership kept both plastic covers off the top of both cars. I told them I want them back and was told manufacture put out a bulletin that after making repairs to oil leak and harness to leave them off? Do you have any idea why as I see in your video, the cover is still on your engine. Thanks!
Its to reduce temp and let more air through. I have never had an issue with mine, but i dont run covers on my buick or the 99 gtp
I'm having mine done as well on a supercharged version as well. Would it not be a good time to change spark plugs and wires while you have it apart?
It would
(At 15:58) Almost sure I had replaced the accessory belt in a way that "made sense", I was left with extra inches of belt, with nowhere obvious to place it. Rather than complete the disaster, I went back for information on the the proper belt routing path, and reinstalled the belt properly. All went well after that, but I drew a crude routing diagram on white plastic coolant reservoir to make sure this avoidable error is avoided.
Ty..great vid..i got a 2000 regal LS with only 68 thousand..but its 20 yrs old..and there slowly leaking and I think my front valve cover is leaking as well because theres little puddles of oil in the valleys/grooves of the engine..do you think bad valve cover gormets could leak...but i had valve cover done.. a couple yrs ago so i dont know why they would be leaking again..maybe bad work iam sure.. Another thing..I noticed when i open my oil cap..there is a puddle of oil that jus sits there..seeing you pulling the front valve cover off..now iam wondering how the hell is my oil jus sitting there..i put my dip stick in ..and its covered about a quarter of a inch up..hmm..and what was the reason again that you had to use plastic gaskets instead of aftermarket metal ones? Ty!! You make this seem so easy..gonna try replacing valve cover myself..but the intake..mm..i cant..thanx again!
Gromets are abpossibility. I had to use plastic because thats what the customer wanted. I advised otherwise. But i have to do what the customer wants.
@@SalemDoyle thank you man!!
So I changed my gasket on my Buick 03 but also broke the elbow that connects to the purge valve. Did u find out the part name and do I need the buy the new hose as well
It should be listed as " evap purge hose " you could probably put something together with just vac hose and some couplers
Hey, thanks for the video. I have a 2000 Grand Prix with what I believe is a blown head gasket. It isn't overheating but there is a good bit of white smoke coming out of the exhaust. Would you recommend using Bar's stop leak to temporarily fix the issue? It has 260K on it so not tryna put much money into it. Thanks!
Bars usually stops up the radiator and heater core.
@@SalemDoyle thanks for the reply, I’m a big fan of your videos. There isn’t any coolant in the oil so it might not be a blown head gasket. I don’t think the intake manifold gasket has been replaced so do you think replacing it will stop the white smoke?
Its worth a try.
the person i need to do this job has to i cant stress it enough has to do the job exactly the way u doing it and it is literally impossible nobody in my area is that smart ppl like to cut corners alot and i wont be able to tell which short cuts they took i need someone i can trust
Plenty of people out there that can do it, just have to find a good shop
@@SalemDoyle someone wanted 500 to do the job others want 400 and only a few will take 300 im trying but this isnt easy at all check fb my car is getting worst idk how to save her and its 23 degrees out side
I have an 04 grand prix super charged.looks to be a bit of coolant in the oil. Would you suspect lower intake? Its winter and my fiancee work car. Need some advice thank you
That is the most likely thing
Do you have to pull the tensioner for just the back valve cover? Or did you pull it for the LIM?
For both
