Hi, could anyone help me with this problem. I find when I have all my windows closed while driving I feel tired after 30min or so of driving. 2 months ago I had the exhaust manifold replaced due to a big crack. I dont have a header. I have a 98 civic si.

Before the repair I could smell the exhaust fumes coming in the cabin. Now there's no smell but I feel the effects more subtly.

Please help

I'm not sure what the problem is...but you should really take it somewhere asap to get it checked out. That stuff is deadly.

Ya I'm taking the car to the dealer to check it out tomorrow. I was hoping it was something I could repair myself, oh well. Has anyone had this experience before?

Just get one of those furnace carbon monoxide detectors for home use and drive with it for a little bit. I very much doubt that it's carbon monoxide in the cabin... cuz as you're driving, the outside air would simply 'wash away' and leaking exhaust. If you're idling for that long, that would be a diff't story.

I just think you get fatigued from other factors. Road noise, boredom, or a nutritional deficiency. But it would be good to get a CO monitor or an air analyzer in the car just to be sure.

A buddy suggested the CO detector too. I may just try that. With the windows open I don't get tired. But yesterday was raining and I had to close them.

It could be other reasons as you said but I always take long drives and never feel this tired in a short time. Thanks for the suggestion.

how old are u 'Stocker'?? maybe its an age thing eh.. or closterphobia

well, having a window open helps you stay awake while driving because of the breeze,

when you take long drives, do you have the windows open?

LOL... too funny. I'm in my late 20s so I shouldn't be over the hill... yet. :|

Should there be a solid gasket between the 4 tubes (manifold) and 2 tubes? Is it supposed to be visible? I ask cuz it seems like they used those 'gasket from a tube' thing to seal it. Thanks

I've taken long drives like to eg. Montreal with the windows closed and I would feel fine. Now after the repair, this tired thing happened a few times where I would be driving for 30min or so and feel tired. This even happened on a clear sunny day with no cars on the highway. I don't get this in any of my buddies' cars.

Please keep the suggestions coming... I really want to figure this out. Thanks

but see, the thing is because the cabin is relatively sealed (ie. the air intake is in front of the windshield) it would be relatively difficult for exhaust gasses to come in while driving, since they will follow the path of least resistance, which would be underneith the car. Yes, the gasket is usually visible, usually metal or a composite donut. (I have an LX so mine is diff't from yours). Pop your hood and start the engine... try to feel with your hand around the area where you suspect the leak to be... BE CAREFUL NOT TO BURN YOURSELF!!!! Or have a buddy plug the exhaust with a rag or his hand (don't worry the exhaust is relatively cool in the first few minutes of running) and you LISTEN for leaks. Better yet, take some sand and sprinkle it in the general area of where the exhaust leak is suspected. A leak will blow the sand all over the place, esp if your buddy has the exhaust plugged pretty good. If there is no leak, the car may stall, which is okay.

Thanks for the tip. I will try that tomorrow if the dealer can't fix the problem. I guess I'm the only one who experiences this problem.

I get tired quickly while driving too, and yah i did have an exhaust leak, and yah i could smell the fumes in my car (at highwayspeeds). Its fixed now (maybe not 100%), i can only smell minor fumes when i really get on the throttle. But i still get drowsy really quick... but thats just me i think, im healthy, but theres something about highways that make me sleepy. I use perkback pills when i really need them, they work great, wakeup brand pills suck compared to perk back, but otherwise cofee usually does the trick, and cold air, ie window open... I usually get drowsy after 30mins to an hour but i only stay drowsy for about another 40 mins to an hour, then i guess i get used to it or somthing, like i get a second wind and i wake up.... its odd ...

btw this happens in driving other vehicles too, with no exhaust problems, so i know its mostly me.

I think its due to me travelling allot by car and boat when i was a kid, i loved and still do love sleeping in the car, i would sleep like a baby. And i also slept allot on my parents boat while travelling when we would go for 2 week trips on it. Something about wind and road noise that puts me to sleep.... So i think my brain is just conditioned to be drowsy and want to sleep when in a vehicle. The solution is my g/f drives at night i drive during the day, its sort of an agreement we have together.

Weird how i cant sleep as a passenger when someone else (besides my g/f) is driving my car tho lol. Im too nervous lol

Alright, someone else feels my pain! Thanks for sharing that BoOsTd.

Unfortunately, I don't like taking pills and I don't drink coffee... so I'm pretty well shafted. This only happens in my car. I can sit in/drive any other car and not feel tired or have a minor headache. My car is cursed or something.

Nice relationship. My last one was not that accomodating
