The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

2001 Chevrolet Monte Carlo Reviews
This 2001 Monte Carlo is the biggest piece of crap I have ever owned. I have spent thousands of dollars repairing this lemon. I've replaced the brain and too many parts to write about.And once again another problem. I can't even drive it to get groceries 2 miles away without it stalling and barely getting back to my driveway. I did find that most electrical parts are made in Canada and they don't use lead in their solder.Then you get things called whiskers that shorts out the Electrical parts. I'm an electrician by trade so I know about Electrical problems just not cars.I had 3 Nissans with 175,000 miles average and this Monte Carlo has cost me more than all 3 combined. It's a pretty car but a major piece of crap.
I bought my 2001 monte carlo LS at 49,000 miles on it. Worked sooo good until about 100k miles when the manifold went out. I didnt even realize until now (100k miles) that none of the cigarette lighters worked. For some reason the place i bought it from said the entire engine needed to be replaced, so we replaced the engine with a new one with who knows how many miles. I dont even know if we needed it but i'm not a mechanic so i just trusted them and wasted around 1100 dollars. (McFerrin motors in Texas, i believe they are snakes)
After they repaired that, the radio didnt get reception either, or just barely sometimes. Now at around 149k miles, there is a huge amount of electrical problems. 3 batteries and 1 new alternator later, it finally starts and drives again. The blinkers work whenever they want because of a faulty control unit which also works as the emergency light activator. The AC compressor doesnt stay on for more than 30 seconds because the engine falsely thinks that the engine coolant is low. I had the temp sensor on the engine replaced to fix the readdout on the instrument cluster, which is always at 0 degrees UNTIL i disconnect the battery for a while, then then the heat starts readin, the ac compressor turns back on and etc. Now it also has ABS issues. There is a loud noise when i start off from a halt but it stops when i take my foot off the gas pedal. After this happens a ton of lights come on, like ABS warning and etc. i didnt know it but when i got the car originally the radiator must have busted, or the person who owned it was trying to fix the manifold themselves by FILLING the radiator with stopleak, which caused the car to run very warm all the time until i replaced the radiator. None of the power locks work anymore. WTF. they stopped working at about 100k miles. The windows still go up and down, and also the trunk open button stopped working as well. This thing is an electrical nightmare. It did serve me very well for 60k miles, but was not worth the 12g's i spent on it. Slow, bad handling. The one thing it had going for it was amazing brakes. Really, sincerely amazing brakes. However now the ABS light comes on now when i start driving. I really, really hate this car. Not because its a chevy because i dig Chevy products, its because this one I ended up with was such a rotten lemon. I have put so much money into this and have gotten a barely decent, crappy radio sounding ride in return. If i could go back in time and warn myself not to buy it, I'd just tell myself "Lets look at a truck, instead. A ford truck." Tommorow some poor sap is coming to pay me 2000 for it, or he says he is. Lets wait until he test drives it. For the love of god let me sell this car. - Sincerely, Rick.
P.S. When I turn the wheel it makes a cracky popping noise. I guess from what i read on the other reviews, an intermediate drive shaft? :/ god damn front wheel drive cars.
Also turns out the type of radiator fluid that is in these cars becomes extra acidic under certain conditions and replacing the intake manifold gasket becomes neccessary on every single car after a while. There was even a class action lawsuit that provided people with x amount of money to repair it.
purchased car used at 158,000 have put 42,000 on it to date.my 1st issue was that the car was overheating at red lights in stop and go traffic,thus the cooling fans were not functioning.shop told me it was the cooling sensor,replaced and no change,shop then said cooling system needed flushed,guess what no change,then said it had to be fan relays,replaced all three, no change,shop said only 1 more option it could be,replace the bcm(body control module) $200.00 for unit,$100.00 to program. fans know work but will not go off,on all the time,even when you turn car off.did some internet searching and found someone with same issues,told me to change thermostat and all my cooling problems will go away,replaced it and guess what,fixed everything!next issue,car is losing power badly,shop says tune up,did this no change.shop says replace coil packs.did this no change,checked internet found these cars have catalitic converter issues,replaced and car now has more power than when i got it!3rd issue car's traction control lights come on when it rains and after i wash it,has progressed to on all the time now.checked internet found wheel speed sensors wire harness's are faulty.4th service tech found bad oil leak on back of motor,losing 2 qts per 3,000 miles.some kind of o-ring gasket on a cap on engine.5 clunking noise in steering,faulty shaft.
Bought this '01 Monte Carlo LS 3.4L V6 in mid-Oct 2008 with 64,000 miles on it. Car ran great when I purchased it, but shortly after I decided to do some tuneup work on the car is when the problems started happening... I first changed the oil and oil filter, air filter and had no problems there. Then I decided to change the belts and hoses and flush the cooling system...that's where the first major issue happened. After flushing the cooling system, I didn't change the thermostat because it seemed to be working ok but after flushing it about 1,000 miles later, my temperature gauge stop working. I then decided to change the thermostat and the coolant temperature sensor since they were next to each other. Pretty crazy just to replace one if I wasn't sure of the problem. Well, that took care of that problem...until the heater & a/c stopped working when it was below freezing!!! Checked fuses and relays and it wasn't that...wasn't the motor either...ended up being the blower motor resistor....another stupid part burnt up!! After that I noticed that my car was running lean after pulling the plugs out to check them. Wasn't sure what was causing it but later but figured out that it might've been the whole cooling system thing that caused it....which somehow screwed up the catalytic converter which needed to be replaced too because somehow one day, the car was unable to drive because it was loud and horrible sounding!! After changing the converter, it took care of that, all worked great until the coolant level sensor went out. Still haven't replaced it...not a big deal to me. Car isn't leaking coolant and it's full. Changed the spark plugs and wires and all of that is fine...but now about 10,000 miles later, I'm having an issue with the security light on my dash flickering and the door locks locking and unlocking on their own and the headlights and interior lights flickering. It's becoming a pain right now! From what I hear this is another common occurence on these cars... Heard the problem is the BCM aka Body Control Module. Haven't replaced it yet but will soon! Good thing I know how to work on cars otherwise all of this would've costed me a fortune at a garage! Other issue that I have with the vehicle is the clunking and rattling sound in the steering column/shaft...It's coming from the intermediate shaft...again, another common issue with most GM cars.. Haven't replaced it yet or greased the shaft yet. You can still drive around the way it is until it just gets to you too much to the point you need to replace it. One last thing that I'll need to replace sometime in the next 25,000-50,000 will be the gaskets on the intake and possible head gasket... Again, another common issue on most GM vehicles from 2000-2005..they used these really crappy gaskets that are paper thin and don't last long! Beyond all of that that I have mentioned... I guess you could say its a good car..lol This is the first car that I've dropped this much money in in less than 25,000 miles worth of ownership... I sure do miss my old Buick!!
