Those valves don’t have the type of “lash” adjustment that you’re thinking about…and those pushrods are not all the same length so make sure you put them back where they came from
Thank you. I guess that's about the '"valve tuning" he mentioned. I took the rocker arms all the way off. Hopefully I don't have to do anything extra. Wondnering about torque number for the bolt holding intake manifold down. Will try to find that info.
I did this on a 97 grand am with a buddy...his kid knocked over the pushrod box we set up and everything went to shit....but everything was fine after reassembly .....probably best to keep everything in order but, not sure it's extremely crucial
This is my time ever doing this is know work on cars just never did this lol when I got the bottom intake off and I out I got stuck wandering how to do it ... bruh your video saved me great job dude
8.16.14. Matt,on 1996 & up 3100s you do not have to adjust the valve lash. Also these engines are extremely prone to stripped rocker arm bolt hole threads in the aluminum head! The tool you show keeps from stripping the threads in the aluminum head. What happens if you don't have the tool, & you loosen the rocker arm bolt, and the cam is coming up to open the valve, it puts a ton of pressure on the bolt/thread junction. That will cause the bolt to pull the aluminum thread in the head! This is the only way to avoid stripping the aluminum threads! The head gaskets also are a common failure on these engines, due to the Dexcool coolant not being drained/flushed completely. I service the coolant every 30k/2yrs! Long life coolant is a marketing ploy for the auto manufactures. Good video! P.S. Timeserts®️ are the best way to repair stripped threads.
Bout to do this same job. So will I need the tool to remove the rocker arms? Also is their a torque spec for putting them back on? Also their is a loud knocking noise coming from the top of the engine and I believe it is one of these rocker arms is that possible and if so can I replace just the one or should I replace all... Doing this job for a friend for free to help them save cash (pay it forward people). Thanks in advance for the advice
ronnie cox 7.13.20. Yes you should have the tool. I believe that the Torque value is 14 or 18 ftlbs. If you have stripped rocker arm bolt hole threads in the aluminum heads, use TimeSerts ®️instead of Helicoils®️
😂 that motor does not have adjustable valves, just pop the rocker arms off and take the pushrods out and put them back in the same order. Two size pushrods in that motor and the valves will bend if you mix them up.
4.4.24. While the Lisle 48300 tool is not absolutely necessary, it makes the job a lot easier. Because in order to pull the push rods out, you will have to loosen the rocker arm bolts. But before you loosen those rocker arm bolts, it’s imperative that you turn the crankshaft and make sure that each and every cylinder that you’re working on is at its top dead center on the compression stroke. The reason being is if you do pull the rocker arm bolts with the valves being actuated by the cam, they are loading in tension the rocker arm bolts thread junction in the aluminum heads hole. Thus risking stripped aluminum threads⚠️ RUclips is replete with videos of people not doing either of these two actions and rocker arms are loosened, making a horrible noise.‼️ therefore, it’s much easier to use the Lisle 48300 tool✅
Hi I have a 95 cutlass ciera and there is a oil leak about middle ways the motor it seems like it's coming from the lower intake gasket or maybe out of that hole where the distributor once was how can I tell
***** hey thanks for the response. I am sorry to hear that you still had the problem. The kit that I am going to buy doesn't include that o-ring for the oil-pump-drive-gear. It only includes thermostat seal, thermostat housing pipe o-ring, and coolant bypass o-ring. Oh well I'm just going to leave that one alone. I am also not going to bother taking the rear valve cover off and the alternator because I am going to buy Lisle 48500 push rod tool, just to speed up the process. After all, my car is still a POS. Anyway, thanks for your awesome video.
My 2003 buick century 3.1 lter is over heating, I changed thermostat then I bypassed my heater core and not sure about water pump but I think it's air in my coolant system because when I turn car off after running hot a lot of bubbles be in coolant box coming from radiator
Many thanks for this video Matthew! I’m about to embark on doing this intake manifold gasket replacement on my 94 Ciera 3.1 liter. Looking for the links to get that tool that lifts the valves
This isn't a SBC, you don't have to worry about setting or adjusting the valves. You can just take them off and bolt them right back on. The only way you can mess up is if you put the pushrods in the wrong location.
oh boy... not sure I remember :/ Do you have a link to a photo by chance? Unfortunately I no longer have the car to look at it. I think for the most part I used box end wrenches and a socket wrench.
The seals were engineered to fail. Mine failed under warranty. The engine bearings were trashed from water in oil. I got new engine. GM knew about this.
@@matthewjeschke Slip some new bearings in from the bottom and run it for another 200,000 miles. Use super glue to take up the slack if the spun bearing has been spinning and wearing the rod cap.
No kidding. I was really torquey. My 3800 is several years newer and won't brake the tires loose like that one would. That said both the 3100 and 3800 I've had issues trying to keep from leaking coolant. They ALWAYS seem to leak which is super annoying. As soon as I patch up one leak another surfaces ug.
Hi great video BTW. Are you saying that there was nothing wrong with the plastic LIM gasket? It was just the RTV in the valley? Because I am experiencing the same problem with my Malibu. I touched that liquid right below the thermostat and it looked like it was oil. -Thanks in advance. Again awesome video
Patrick Macalalad yeah I believe it's the RTV sealant. However, if you tear it apart you really should put a new metal gasket. FYI. The gasket was only 1/2 my problem. Upon putting mine back together it still leaked :/ I should have also put RTV sealant on the plug where they use to put distributors. I believe that is also a source of leaking. The little rubber o-ring they give you for that simply isn't enough. I should have RTV'd the surface where it meets the top of the block.
You are correct. I was thinking of my SBC which I changed out the rocker arms on and had to adjust lifter preload. Either way, if possible I'd advise to leave the rocker arms on. I did this such a long time ago, I don't recall why I even pulled the pushrods out of the rocker cups like that.
@@matthewjeschke So they're out of the way of the gasket swap. Did the same on my 1999 Chevy Lumina, like 10 years ago. Looked into it recently to find a video to refer somebody to who has a newer vehicle with same architecture engine. By 2009 they might have changed to a better OEM part though, IDK.

Thanks for clarifying. I don't know why I got into talking about valves. I've only really done that on V8 stuff. Going to pin this.
Good tips, motor looks pretty clean inside!
Sure did! Was happy it wasn't worse :)
This is my time ever doing this is know work on cars just never did this lol when I got the bottom intake off and I out I got stuck wandering how to do it ... bruh your video saved me great job dude
glad i could be of help :)
Don't hurt yourself kid
good tip on the rocker tool, Had no idea thay had something like that will have to check it out before I continue with my gasket job.
Glad I could help out!

ronnie cox 7.13.20. I’ll have to check on the Torque value
Thank you.. very good ,sir just need a light,,but over all very damn informative and takes the anxiety out of doing this

Yep this is correct. No need to mess with rocker arms just torque to spec
do you mean tuning as in calibrating valve slash? i might be wrong but i dont think you have to do that you have lifters set up not overhead cams
The coil pack plate stud is a 5.5mm to remove it.👍
There is no "tuning" of valves, they are non adjustable, simple hard stop on their bolts. That special tool was a needless expense.
Yeah I don't recall. I don't remember tuning valves on my 3100 maybe I said something in video? I did it on my Gen II SBC

My 3400 is dripping coolant in the same spot that yours is dripping oil what I that mean I have no overheating or oil and coolant mix???????
Hi I have a 95 cutlass ciera and there is a oil leak about middle ways the motor it seems like it's coming from the lower intake gasket or maybe out of that hole where the distributor once was how can I tell
you can add a contrast dye to the crankcase. Then use a blavk light. It will glow where the oil is coming out of.
Thanks for the video. I'm interested in Rocker Arm Tool link ?
I have no clue if they even make those anymore. I switched to a screw style that goes on the stud.
4.4.24. Lisle 48300 rocker arm tool✅
@@stevensapyak7971 thanks for helping out.
Where do I go to find the links to the tools
You mention in the video?
should be in video description. otherwise you can find them with a quick search on amazon.

how did you remove that tricky bolt behind the valve cover bolt?

Those are not adjustment type lash so there’s no adjusting needed.
The seals were engineered to fail. Mine failed under warranty. The engine bearings were trashed from water in oil. I got new engine. GM knew about this.
Oh wow. That engine finally went around 200k miles. It spun a bearing.
Yes they alwas do in a rod bearing@@matthewjeschke

Good ideas got a 2001 myself with same leak
So I use lisle tool I dont have to re-tune the valves
That motor is a good motor, but the original intake gaskets was a huge mistake by the GM whom wouldn't admit they were faulty.
No kidding. I was really torquey. My 3800 is several years newer and won't brake the tires loose like that one would.

How do I tune the rocker arm ?
crtrue2000 I heard they sell some tool to where you can remove the arm then put it back without tuning it again I seen the video here on RUclips
"Compound angle " valves.
You DO NOT tune valves in this engine, that's not how it works.
You are correct. I was thinking of my SBC which I changed out the rocker arms on and had to adjust lifter preload. Either way, if possible I'd advise to leave the rocker arms on. I did this such a long time ago, I don't recall why I even pulled the pushrods out of the rocker cups like that.
