CHEVY 3100 V6 HEAD GASKET REPLACEMENT HOW TO

[@jerleh261]

If anyone is needing to do this, some advice. You don't need to take the fuel rails off unless you want to replace the o rings for some reason, just disconnect the lines and leave the rails attached to the plenum. They will just come off with the plenum. Also, I disconnected the exhaust crossover and pulled the head with the manifolds still connected. Thanks for the vid! Very helpful!

[@solesoul2108]

My 00 malibu had oil and antifreeze mixed, I've never done a teardown of this magnitude and this video helps, thank you!

Diesel mechanic working on a gas car…. Scratching my head quite a few times. Understand the mechanics but these tiny things are hard to work on like 2x the patience I normally have to have 😂. Your video helped me and as a mechanic I appreciate it! P.s. I did send heads out to be checked and cleaned before re install. Thank you!!

[@royzcustomz]

You are welcome.

[@dwaynemadsen964]

15:20 Once these bolts are in a ways, I was able to get a wobble extension on a short socket and finish them off. To get the one on the right (passenger side) down far enough I used a ratcheting box end wrench. I was getting 4 clicks per turn on a 72-tooth ratchet. Fortunately, the bolt went in easy so I was able to go almost faster than I could count! Thank you for sharing and stay safe.

[@prestonford901]

Thank you so much! This video helped me and my dad install new head gaskets!

I know I am late to the party, but I use an upside down egg carton to keep my push rods in order. Just a little tip. Good day and happy motoring 😁

[@royzcustomz]

Not a bad idea

[@wyattandwill12]

That's a great tip

[@amoscrowe596]

Of all the videos and instructions I looked at, this one is one of the better ones. But it is not quite as simple as it looks. There is a lot of missing information that is really important for newbies. This not a job for anyone that has big hands. My wedding ring is size fourteen and I had to do a lot of extra work and disassemble many things to get at some of the nuts and bolts. This guy just shows you all the easy stuff and if you don't have any mechanical experience, this is not a job you should do by yourself. You will need many different kinds of ratchets and ratchet wrenches to get at some bolts.

[@royzcustomz]

thank you for watching the video. I want to start off with yes, you are right this job is not for the newbie, it is mostly so people can see how much is involved and it is more for someone who at least knows what they are doing but has not yet done this particular job before. there are a few things that need to be removed to get them out of the way. If you look through the comments it has helped many people get the job done. as far as the job not being for people with big hands I totally agree because my hands are not huge but they are not small either so it was rough getting through some of the job myself. I will try and do a better job and be more thorough with my videos in the future.

[@bernardd.partridge3152]

You did it the exact same way I did it other than remove the battery and air filter box, but imma take my heads to the shop because the car overheated and the engine shutoff.

I didn't take mine in because mine checked out good.

[@royzcustomz]

Thank you very much 😊

[@benjimartin8853]

I just assumed that you had to head machine right but other than that the video was awesome real informative I thought it was great

[@royzcustomz]

You don't always have to machine the heads just make sure you check then ri make sure they are level and then clean them up really good and you're good to go😁

[@wyattandwill12]

Right now I'm just trying to remove the fuel rail and I'm gonna do the heads later, but I'm having trouble getting the part of the fuel rail toward the firewall off, the rail isn't wanting to come off the line. I'm gonna try using rags to help with grip and maybe that'll help. My car's 21 years old and the o-ring has probably never been removed so it's difficult.

[@royzcustomz]

Mine was a little rough to get off too.

[@wyattandwill12]

@@royzcustomz I ended up getting the quick disconnects in the back off but one of the lines are still connected. I'm thinking about taking the fuel injectors to a mechanic so he can clean/test them and put new o-rings on and see if he has any ideas on how to get that line off of the rail. I'm gonna grease everything up in case anything has to be torn down in the future and I wanna replace the fuel rail o-ring. I don't exactly have to but if he can get the line off I will. Thanks for making the video it's been very helpful and once I can buy all the gaskets I'll be a step closer to getting the engine running right again.

[@juliebunderson6201]

Hi, I'm super new to fixing my own car, but I know I can do this if I have the right tools and specific instructions. You're video is awesome, but not quite thorough enough for a newbie like me. Do you know of anywhere where I could find written diagrams/instructions that fill in all of the blanks that people with experience get, but I don't yet? Thanks so much for responding if you have the chance!

[@juliebunderson6201]

@@royzcustomz Cool. Thanks!

[@Whiz_Witt]

Thank you for the video I have watched it about 15 times as I am just starting to replace my head gaskets. I had a quick question the 2 ignition coil bracket bolts that have to be removed to access the rear valve cover what tools/process do you use to remove them? I have used PB Blaster and a 5.5mm socket on the tip of the bolts but they seem to be starting to round out and I’m not sure I am doing it right

[@royzcustomz]

If they are rounding off you might have to use an easy out. It's been a while since I did this job but as I remember I didn't have a problem removing those bolts.

[@NickHairston]

Can you make a video about just removing the intake of the Malibus from 99-03? I can’t find anything that helps.

[@royzcustomz]

It will take me a while to do a video for that because this is my mothers car and unless it needs work done to it she drives it everyday, but thank you for the suggestion and I will surely make a video for that when the time comes. If you can find something that covers the 3400 engine then that would help you out in the mean time because they are pretty much the came engine in many many ways when it comes to the assembly of the engine.

[@TheHighRoadToVictory]

You probably drain the coolant first right?

[@royzcustomz]

Yes, it does help...lol

[@georgerhodes556]

Well done.

[@royzcustomz]

[@benjimartin8853]

I hope you remembered your dipstick bolt. lol good video!

[@deathofnight101]

Ay brother idk if you still here or not but did you do the backside or is the backside an engine pull? only seen the head on the front

[@royzcustomz]

Yes I did the back side it's just easier to film the front so I didn't film doing the back head but it's pretty much tha same process as the front.

[@Elswalbe]

I have been digging and scratching my head. the Belt side dogbone mount is in the way of one of the main head bolts. Your video skips past that step; any advice on getting that out of the way?

[@royzcustomz]

I didn't have anything in the way of the head bolts. I removed anything that could be in the way of the head bolts or the intake bolts.

[@Elswalbe]

@@royzcustomz That's extremely vague!

[@royzcustomz]

@@Elswalbe I'm sorry but I didn't have anything in the way of my head bolts. I did have a couple of lower intake bolts that was a pain to get to. I had to remove a couple of brackets to get to those but other than that didn't have to remove any motor mounts.

[@silva862006]

I did this procedure on a 03 Grand Prix SE. To remove beltside dog one mount bracket remove the 3 bolts holding the AC compressor in place. 2 long ones on top and one on bottom. It will make sense when you see it. Hope it helps buddy!

[@stephannerkowski5223]

Any need to adjust valves after removing and replacing push rods/rocker arms?

[@royzcustomz]

Nope

[@fun1brians]

I have antifreeze in the oil. Do I just drain it and put new oil in or do I have to change it a few time$. I was thinking to just drain it and refill with a new filter.

[@royzcustomz]

I just do oil and filter change and then after a few weeks of driving I change the oil again. I know it sounds like allot but I like to be sure the moisture is out

[@leghumper1574]

I've got both do you flush the coolant system to clean the oil out of the coolant?

[@justinsample9683]

Soo what about the back gasket lol

[@wyattandwill12]

I know you commented a year ago but especially for anyone else wondering, the back gasket is the same part and you need to take the exhaust off plus whatever else is in the way, I disassembled a long time ago so I can’t tell you for sure without getting my Haynes manual out. I needed an impact wrench and multiple extensions to get the exhaust off and the exhaust manifold bolts and studs are probably rusted so be careful, I broke a stud.

[@matthewpearson7584]

Bruh that’s the one I’m struggling with

[@dylanhale7300]

Don't know if you still reply, my car overheated a couple times before I diagnosed the issue. (Stopped driving as soon as I saw oil in the coolant, thought I had a radiator issue until then...) If my heads are warped, what are my options?

[@royzcustomz]

you might be able to get them milled if they are in tolerance. you may get lucky and find a set at the local parts yard for a good price. (hint) if the car at the parts yard is wrecked more than likely the engine is going to be good. I'd pull it apart and see if it's just the gasket first.

[@danielsmith636]

I got a 2002 Chevy Malibu 3100 V6 it's not the lower intake manifold gasket leaking it's not leaking into the oil yet do you do this kind of work people can pay you to do it

[@royzcustomz]

I do from time to time.

[@codymoreland4496]

I know this video is old but I've got a question if you have an opinion to give. My wife has an 01 malibu. Same car. So its 20 years old. Its leaking oil out the head gasket on both sides. The csr has cost us nothing. It was free like 6 years ago. Should I bother going through all this for a csr with 195k? It only leaks roughly a half quart between oil changes.

[@royzcustomz]

To be honest, it's up to you. As far as what I think, it was free so putting a little cash into it and some time wouldn't hurt anything. They are pretty good cars.

[@codymoreland4496]

[@kyledaylajeunesse4867]

Is this the same engine that is found in a 1999 Chevrolet Lumina? I have recently blown head gaskets and have decided Im going to try to replace them myself instead of paying over $1500 for a mechanic to do it.

[@royzcustomz]

if you have the 3100 it is the same and even if it is the 3400 the torque specs are the same for the 3400. they have the same block the heads are a little bit different so you have to have the right gasket kit.

[@mrkeitt]

Great video. I have this car in the shop and my mechanic is easily distracted and a bit talkative. How long do you think he's gonna have this in the shop from your opinion?

[@royzcustomz]

About a day maybe two as long as he can focus and he can get the parts and the heads are good.

[@mrkeitt]

@@royzcustomz Thanks for the reply. He's apparently trying to get it to me by day's end. He sent me pictures saying there was some pitting near the cylinder head so he's gotta address that as well. The car has been overheating regardless of bled system, new temp control switch, and thermostat. Hopefully I pray this fixes the overheating issue 🙏🏾🤞🏾🙏🏾

@@mrkeitt a bad intake gasket can cause over heating as well due to the gasket leaking at the water jackets

@@royzcustomz How bad is pitting? I mean I know it's not great. He sounded like he'd had a plan for it so I assume it's not too crazy.

Yes, but for the video I didn't see a need because it's the same process.

[@AlleluYahShoesMinitries]

My overly curious cat knocked over my push rods & rockers. How do I reinstall them properly?

[@royzcustomz]

not really any way to do that unless you know exactly which one came from which cylinder. I would say you might have to bite the bullet and get a new set, unless you want to take a stab in the dark and hope for the best. I have seen people get away with just putting them back in any old order. just remember that one set of push rods is for intake and one is for exhaust.

[@kingketes264]

Hey man i got a 95 cutlass ciera with the gm 3100 also that im changing all the gaskets so i found the cylinder head to block torque spec is 33lb-ft but i can find any of the other bolt specs for intake manifold and fuel rails n the rest of the stuff. You got any info on that?
