You are a legend!!!! I have been searching everywhere with no luck so far. I am aving a problem with black smoke and bad acceleration, figured it might be a skipped timing on the exhaust cam.
I want to thank you very much for this vedio it was very timely to me, God bless you for sharing your knowledge and time freely with the world.
Finally a video that I can understand.. those other guys were saying "this thing"and "whatever this is"
perfect video up load thank you helped me get my 2.4 timing done
nice video. thanks for your little story about the lifters... much help.
Thanks I just bought a grand am with the twin cam in it. Its my every day car. It has about 190k on it but the water pump is going. I pulled another engine from pick n pull and I'm rebuilding that engine so I can drop it in and not have to worry about engine problems for another 20 years. I'm only about 800 into it and it's almost done
Excellent video on doing the timing. Much appreciated making this video it helped me a lot!!!
this is an excellent explanation on how to installed a 2.4l ld9 timing chain and set the gears and tensioner thank you !!!!!!!!!!!! maybe next time you do a rebuild you can do a walk through step by step
I'll be creating a motor build video series soon. Thanks for watching.
Thanks for the detailed video on how to set the timing you made it virtually easy to get it done with confidence. i Appreciate you very much.
You're welcome! Thank you for the compliment.
Thanks for showing the way. Also, I did your shirt! Thanks for showing THE way!! :D
Great video very very helpful and knowledgeable especially on an awesome motor thats not often done and theres not much info on.
greetings from mexico. great video. I learn somthing today. thank you very much.
Thank you so much for this video couldn't done the job without it again think u
Used your videos and info on a recent cylinder head change on my ld9 cavalier, great help thanks.
Wow, that's great! Thanks for the feedback. :)
Yes sir, great to have guys like you showing those of us do it yourselfers. Been stung too many times, hard to find an honest mechanic so gotta do what I can myself to save money and know the job is done right.
I am rebuilding a stock one now for my daily driver. I have a play list on my channel. I've got the bottom end together and now that my garage is freed up for a while I am hoping to get the head on it soon.
I have one of these in a 90 cutlass Calais international edition i'd like to rebuild and stick in my 78 Mercury Bobcot. I think I'll take a look at your videos. =) (I wish the bell housings to adapt these to RWD Transmissions weren't $600).
Great video!!!
Thanks for the video!
Thanks My Friend from Querétaro city
очень помогло видео!! спасибо
Good vid
good job
Thank you for the video. I’m working on the timing chain for a 2001 Chevy cavalier with the GM 2.4L engine. I suspected this car had a timing issue for a while, because whenever you let off the gas it would backfire slightly. Then, all of a sudden it just started running poorly with misfiring randomly. It threw code p0300. I suspected timing for a while and just dove right in. Upon pulling the timing cover and pinning the camshafts in time, I noticed that the crankshaft spur gear looked like it was about one tooth possibly two past the mark for TDC. If the chain had jumped, wouldn’t the cam gears be out of alignment as well? I ask this because when I pinned the cam gear with the pin through the hole in the timing housing, I was able to pin the other cam gear as well. If the timing had jumped a tooth, I wouldn’t think that both cam gears would line up with their timing marks. Is it possible that the crank gear could have free wheeled a bit and the tensioner took out that slack and allowed for the cams to stay in time, at least relative to one another? I’m not sure if it’s the original chain or not but I’m sure it is possible that someone could have installed the chain incorrectly after having not set the crank gear at TDC. Just looking for some input on this. Thanks in advance!
Execelente video!?
Perfect
Thanks
Thanks a lot man you are amazing
Thenk
You really are gonna race it, huh? Now you've got my attention. What car is that going in? I had a '88 Grand Am with a Quad-4. My favorite thing to do was smoke Hondas with loud exhausts. Fun stuff. Fun stuff. Until getting rear-ended, turning it into an accordian.
Yes, we race this motor. You can see it in action on other videos within my channel. Thank you for the comment!
Muy. Bueno. El. Video. Metro. Pregunto. Cómo. Se. Sincroniza. La. Bomba. De. Aseite. Saludos. De. Tabasco.
The Chiltions Online and my factory service manual said to go clockwise 90 degrees and then come back counter clockwise once cams were pinned, which is what I did, but I don't think it would matter because 2 and 3 would be down half way either direction and heading down when you came back to TDC on 1 and 4.
I've actually talked to others about this. Some go clockwise, some counter. I believe you're right...it doesn't matter.

Just wanted to give a huge Thank You to all who've watched, liked and/or commented on this video. It's currently at 26k views! I'm blown away! With that said, I'd like to ask for opinions: Shoukd I monetize my channel or set up a patreon account? I have more content planned and would really appreciate any constructive feedback. Thanks, everyone!
Great video. Thanks. I got a question. my 2.2. Is making a noise, I have replace the water pump, I dont know was wrong,
I need some help on this.
Well, a noise could be nearly anything. Does it get louder after it warms up? Does it get louder when you rev it up? Does the sound change with rpms?
Buen video podrian traduccirlo a español🙏
Was wondering, what size bolts did you use to insert into the cam gear aligning holes?
8mm
Question, I'm doing right now what you did on the engine. How did you install the harmonic balancer? I'm having hard time finding a tool to fit the crankshaft to install it back. Or did you use the crank bolt?
You can just use the crank bolt to pull it on. It will slide on easily. Depending on what year or resource you use for torque, it's 129 ft lbs or 133 ft lbs. After that it's another 90 degrees to reach final torque. That can be tough.
Excellent video. Would like to see more. Do you have any removing the cam covers. I need to replace lifters.
I have a build series on my channel. Not up to the cams and lifters yet but will be soon.
I've been doing a ground-up build of a quad 4. It's in my playlists.
Do the marks on the cam and crank need to be aligned when putting everything back together
The timing mark on the crank gear gets lined up with the mark on the block. The cam gears are locked into position with M8 bolts as shown in the video.
Adam from Poland
My name is Adam and I live in Poland. My car is a 1990 Pontiac Grand Prix. I have trouble with the engine that when starting, when it is cold, rattles very loudly under the timing cover. It takes a few seconds and then it is normal. When the engine is hot, you can hear the sounds from under the timing cover but much more quietly. My timing is type 1, has double gears and the chain is also double. The tensioner is type 1 (BT188). I dismantled the cover and everything is fine, the chain has no play and the wheels are not worn but it all makes a lot of noise. What can I do ? Can I buy a type 2 tensioner? will he help and will it fit? Should I also buy a new chain and sprockets? Or maybe you need to use a new type of chain and sprockets (2nd design)? Will it make it much quieter? I am asking you for help, because I really like this car and I have it for 24 years.
Looking at the date that you did this Video , very recent I see . I was wondering who is working on Quad 4s anymore until I heard you say . You were ready to go racing . What class do you race with a Quad 4 . I have been racing one starting in 1987 . Has to be very competitive engine in any 4 cylinder class , I would sure think . Great job on your video
Thanks! I race in a Sport Compact FWD class. It's dirt oval racing. These motors are decades old but can hang in there decently well.
What other engines do they run in that class ? I have been racing a quad 4 , starting in 1988 when GM sent me a test engine to run in a F/Dragster . I got one of the first 180 hp engines made , and I am still racing it today . I never did put it into the dragster , because NHRA had no idea how small the 4valve OHC engines were . So we could not get down to the minimum weight . So I built a snowmobile around the engine . I have run the engine in many different configurations . Starting with the speed density FI , then changing to sheet metal intake w single throttle body , then dual throttle bodies , but always dealing with the factory rev limiter . So then I changed to Webbers along with a distributor I made to eliminate the rev control . I also built a intake manifold for a Holley 780 carb . On the engine dyno the engine made 233 Ib ft tq @ 5300 and 291 HP at 7400 rpm . I still have a ton of parts for the Quad engines . This is a great engine , the sled weights 1154 lbs with me on it and it has ran 154mph .
First, you should really check out the Oldsmobile Quad 4 Twin Cam Facebook page. It's a great group with some very knowledgeable folks.
As far as what motors everyone runs, around here Neon's are everywhere. Longer tracks favor Cavaliers with the ecotec. There are some Honda's too. Most rule packages state: "Must be stock appearing." So it's pretty much open competition for all the Honda guys.
Hello hoping you see this comment and can lend some advice!! My quad 4 motor has the other style of tensioner where the tensioner and shoe are separate, and I broke the little piece of plastic that holds in the extra spring that yours doesn’t seem to use. Would you happen to have one for sale, or is it even that important can I run it without the spring? It seems like the tensioner and shoe are doing their job and the little spring isn’t helping too much anyway!
I may have something here. Please email me a picture at mpclass3@yahoo.com.
Hi LD9 i have a little trouble with the timen chai i have the sprockets on tieme, the top is tight but the side on the longes guide isn't really tight like the top and u have everything on time what willi be the problem?
I have a problem with my 2.2 Ecotec cavy. When the engine is cold, it sounds completely normal, but after it warms up, it starts to tick. I've also noticed that when I'm idling in park the tick gets louder, but when I move the wheel, it stops. What could it be?
Spun rod poss. IDK about the moving wheel part...
Use a mexhanics stethoscope to pinpoint what area it is comong from. A spun rod bearing will not be a small tick.
The top cam gears are there timing marks?
There is a little hole in between that represents the timing marks. Smaller than all the others.
i put the timing chain all back together now i have a knocking noise can it be the valves.
Could be one of 3 things. A bad tensioner. Bad lifters. Or, the bottom end is out of it. You should note, these motors often make a lot of valve train noise after a rebuild. It takes a while for the lifters to get pumped up. If you had the head and cams off or you're running new lifters, that could be the cause of the noise.
Need to learn about quad 4 e,c,u reprogramming on my sand rail its has fresh air intake and 1/2 THE EXOUST IN A MUFFLER NO CAT NEED SOME HELP THANKS KIRK
Join the Oldsmobile Quad 4 Facebook page. Lots of knowledge there.
@@LD9user thanks brother I will try that it seems to run good but stumbles on low end
Hi!!! I have a question? How many pounds are the 8mm bolt on the tensor and I install the tensor but the tensor get stuck. Any advice? And thanks for the video it helps me with the time chain
10 Nm or 89 lb in
Great video! I’ve been recently having a ton of trouble with my 95 2.3L, after watching your video I’ve confirmed that I’m lost because I’m having a ton of timing slap with brand new chain, gides, and tensioner. Still a ton of slop any tips?
Are you sure it's the right chain? The 2.3 and 2.4 chains are different.
@@LD9user it’s a GM 2.3L out of a junk yard Oldsmobile. From what I’ve been able to find is that in 97 a TSB came out saying basically every time you remove/replace the timing chain that a new tensioner is needed. It seems like my tensioner “piston” won’t spring out all the way even when i release the lock. Do you know if the 2.4 chain is smaller? Will the tensioner gain pressure when oil pressure is present?
@@alexreilly4624 here ya go.
th-cam.com/video/y81GIAkjekM/w-d-xo.html
@@LD9userjust saw this! Thank you! Are the sprockets different from 2.4 -2.3 as well?
How would you take off cam bolts to remove the head?
You have to remove the timing chain and gears and the timing chain housing.
What size of bolts did you use to lock the can gear? DVD:)
8mm
@@LD9user Thank you ! am about to replace chain and gears since i have to change the water pump.. :) DVD:)
Would love to know if the one piece tensioner locks closed if not where can I buy it cause I'm now having to pull the head again due to tensioner locking closed and jumping time
I've only seen one failure with the single piece tensioner. Several with the two piece units. Rockauto has them. 1992 grand am with sohc 2.3L motor. That's the one I use.
Thanks for the update
What's the difference between a 2.3 L and the 2.4 L and am l correct to say that this engines interchange. I have a 95 2.3 Pontiac Sunfire I am needing to put a 2.4 in the car. Do to a so called cracked block
The 2.4 will bolt right into your 95. The upper motor mount is the same. I believe the lower mount is different so you will need the 2.4 lower engine mounting bracket (the part that bolts to the motor). You will need the 2.4 exhaust manifold and down pipe to hook up the exhaust. The only other thing you'll need to convert a 95 quad 4 to the 96-up 2.4 is to modify the knock sensor mount on the back of the block. They were changed a couple times after 95. My suggestion is to make your knock sensor adapter while the motor is out of the car so you'll have plenty of room to work.
Hey there man. I have the same engine. It has a very bad rough idle and is misfiring. Most of the time it won't even stay running put it in gear it shuts right off. I replace coil packs fuel filter ignition control module still having the same problem. Would think it might be a stretched timing chain. Or can kind of point me in the right direction it would be greatly appreciated and thanks for the great videos. Also getting good fuel pressure and i clean fuel injectors. And I checked to see if I'm getting fire to all four plugs yes I am. If you could help please thank you.
First step is to check the computer for codes. Bad plug boots, MAP sensor or oxygen sensor can cause what you're describing.
Here's a video of a race I ran with a misfire. Motor was hardly running by the end of the race. Problem was traced to a bad O2 sensor.
th-cam.com/video/ZFJwTY6JuG8/w-d-xo.html
It's like it has no power at all like running on 2 cylinders but all cylinders are firing.
Check compression if thats good, check the egr valve , they sometimes get stuck open and you lose engine vacium. Its just a matter of removing the piece of carbon stuck in there. Hope this helps
I have two motor 1991 grand am Pontic 2.3L high output one in sand trail other on stand both run and thank show about how chain timer
The sand rail sound like a lot of fun!
Greetings from Hungary.Awesome video mate.Now i won't pee my pants that hard If i ever need to fiddle with the timing on my alero :D
Nice. Thanks for watching. I'm going to be doing a ground-up build series soon. :)
Where is the reluctor wheel for the crankshaft position sensor?
It's located near the center of the crankshaft. Cast as part of the crank.
@@LD9user oh not good,
@@LD9user does a 2 wire crank shaft position sensor have continuity, for some reason im not getting a ac voltage reading or continuity from the sensor its self, so i bought a new one and same thing no ac voltage or continuity, so then i bought another new one from a different store same thing, am i doing something wrong here
Thanks for the vid, Lord knows it's a bitch to reinstall that timing chain.
The quad 4 is a 2.3 L right? Is there a quad 4 2.2 L also?
The quad 4 is 2.3. The 2.4 is known as the Twin Cam. Some use the Quad 4 nomenclature when referring to the Twin Cam. There was no 2.2 liter Quad 4.
@@LD9user I'm thinking of the 2.3 my bad. I've heard a lot of bad things about the quad four and some of it's from my own experiences. I would never own a car with these piece of crap engines.
They make good power but aren't the best design. Of course, it is 80's tech. ;) You would probably be happier with a Honda.
This car dealer tried to sell me a HHR with a quad 4. I looked at the engine and I said that is a quad 4. He said yes it is and said I am not interested. He then starts lying telling me it's not a quad 4 and he doesn't even know what a quad 4 is. He also had two other cars that wouldn't even start. I walked off the lot and didn't come back.
Car dealers know little about the products they sell. No HHR ever came with a quad 4. They use the Ecotec.
So this is just as easy when the engine is still in the car I assume? HAHA!
Ah, that's a no. Lol.
Please
