It would be best to get a copy of a GM factory shop manual for any W car that uses this engine and carefully follow the procedures described. There are 2 things that will make this job easier however. Lisle makes a tool that allows you to compress the rocker arms so the push rods can be removed (they pass through the lower manifold) without disassembling the rocker arms. They also make a tool that will allow you to rotate the engine forward making this job easier and provide access to the rear spark plugs. Also be sure to use the GM gasket upgrade kit and new manifold bolts and torque exactly to spec. Follow the procedures exactly as it is easy to assemble things out of sequence making the next step difficult or impossibles. I have successfully done this job at home and all fluid leaks were corrected. But it does take an entire day or 2. It is important not to treat these engines like an old iron V8. Stay away from them with the old air wrench.
What else can I help you with?
What is the pushrod order for 1996 lumina 3100 v6?
the intake pushrods are shorter of the 2, all intake valves you can see with the intake off those pushrods go there, the rest are exhaust pushrods install in remaining holes
No compression on 3100 motor just changed the intake gasketthe car is a lumina?
The intake and exhaust pushrods are different lengths. If you mix them up you can cause bent valves upon the first crank which would cause a no compression condition.
What are the torgue specs on rocker arms on a 2001 malibu 3100?
All of the torque specifications for vehicles can be found in Haynes Repair Manuals available at most auto parts stores.
Why would gm 3100 engine have no spark?
There could be many reasons why the engine has no spark. A few reasons could be that the starter or starter solenoid is going bad, or the battery is drained.
What are the potential problems of a 3100 GM engine?
the biggest problem these engines have is lower intake manifold gasket failure. this is because gm used nylon gaskets and the anti-freeze eats away at the gasket as the antifreeze gets older. LIM gasket service life can be extended by flushing your cooling system every 2 years and keeping up with cooling system maintenance. another thing i have heard is they have head gasket problems. now i don't really believe this because my mom's boyfriend has own you Buick Skylarks with this engine and I now own a 95 Chevy Corsica with that engine as well. One Buick had 138,000 miles before we got rid of it and the other had 195,000. Both of those engines had the original head gaskets in them. my corsica only has 44,000 miles on it so i can't say much about it yet. but i can say that head gasket failure can be avoided by maintaining your cooling system as i stated earlier and if the car starts to run hot pull it over before it actually over heats. i replaced the oem 195* thermostat with a 185* thermostat to reduce the engine operating temps in my Corsica. And one more problem that alot of GM's have is piston slap. there is a website out there called www.pistonslap.com that says that piston slap is this terrible thing and all that, its really not. remember the 195,000 mile Buick I talked about? it had it since it was bought at 60,000 miles and it ran fine at the high miles. piston slap really is harmless, its just a noise. so if you keep up with the cooling system maintenance and the car your looking to buy has already had the LIM gaskets replaced...the engine is a fantastic engine. i love my Corsica that has it and I loved driving the Buick's too. It really has some get up and go. Head gaskets and intake gaskets are to of the big problems with the 3100 but their is also the problem of the camshaft breaking
How do you change the intake manifold gasket in a 3100 Chevy lumina?
take it to a mechanic
Can water leak from the intake manifold gasket in a 3100 Chevrolet?
Yes it can but the intake is probably the bad guy. General Motors had alot of problems with them.
Where is the coolant temperature sensor on a 1995 Monte Carlo ls 3100 v6?
Look where the thermostat is attached to the intake manifold
What is the purpose of a manifold in a 1957 Chevy pick up 3100 series?
The intake manifold distributes the air fuel mixture from the carburetor to the cylinders. The exhaust manifold collects the exhaust gases from the cylinders and directs them out the exhaust pipe.
What are the intake manifold torque specs for the 1996 Oldsmobile achieva 3100 V6?
Haynes manual says 115 inch pounds- Start from center of intake using a criss-cross pattern, working your way to ends of intake.
1999 Chevy Monte Carlo coolant leak 3100 engine near intake manifold can anyone help?
I just had my intake gasket changed on my 99 Monte Carlo for the same thing. My cousin is a mechanic and has changed the same gasket on several cars with the 3.1 engine. The gasket is about $60 - $75 plus labor.
When looking at a v6 3100 engine how do you tell what is the intake and what is the exhaust?
The intake portion of the 3100 starts where the throttle body (where the accelerator cable attaches) attaches to the plenum (upper intake), below the plenum is the lower intake. The exhaust manifolds are between where the Exhaust pipe connects to and attaches to the cylinder head. The first answer is great, but here's some more as I have just finished replacing the intake manifolds on my 1997 Pontiac GrandAm with the 3.1L engine. First of all, this is a two-piece manifold which is unusual, the first one I've see like this.... This engine is a 60 degree V configuration, and the lower intake manifold bolts directly onto both heads, essentially filling in the center of the "V", and providing air/fuel to the head intake ports. Its mostly obscured by the upper intake manifold that bolts directly to the lower portion. The upper and lower intake manifolds are cast aluminium. The exhaust manifolds are each on the outside of the "V", and bolt directly to the heads. They are cast iron (usually rusty iron color), and are covered by silver sheet-metal heat shields. There is a crossover pipe that connects them to a collector which connects to the rest of the exhaust system.
Why does my 98 grand am 3100 engine loose coolant about half a gallon a mouth can't find a leak?
most likely your intake manifold gasket is blown and is leaking dexcool into your engine. take it to a repuitable mechanic and it will probably cost at least 500 to fix it. but if you continue to keep driving it like that, your motor will freeze up and youll have to switch them out. research it on google, there are many lawsuits against gm about faulty intake manifold gaskets
Where is the oil filter on a 1955 Chevy truck series 3100?
The oil filter was an option back then. It may or may not have one. If it did have one it would be mounted to the intake manifold on the drivers side and highly visable. We used to call them the "crap can". The filter is a cartridge type inside the can.
Why would there be gas coming from your intake of your 3100 when you turn the car off?
Check your Fuel Pressure Regulator under the intake plenum that is on the fuel rail. Had the same issue myself, gas coming from the intake.
Where is the camshaft sensor on a 1995 Chevy Monte Carlo?
i do believe that the camshaft sensor on the 3100 v6 motor is on the passeger side of the motor underneath the intake manifold and under the powersteering pump. i needed to replace the one on my 1996 lumina with that same motor and that's where i fould it. hope this helps.
What is the pushrod order for 1996 lumina 3100 v6?
the intake pushrods are shorter of the 2, all intake valves you can see with the intake off those pushrods go there, the rest are exhaust pushrods install in remaining holes
