I noticed in the past few months a faint burning smell (almost like diesel exhaust) after I run my 04 MCS through the gears from 0-75mph. Its ONLY after I get the RPMs up just shy of the redline with 1-3 gears. Its a faint smell, but distinct. I always just thought I was behind a semi or something, but after a roadtrip, I noticed it when I was the only car on the road.

Aside from that, it runs great. Is this normal?

 

ditto

 

If its the smell I get then it's normal. Everytime I drive my car hard I get that smell and then it quickly goes away. I grew used to it and actually kinda enjoy it. The dealer said it's the carbon burning off.

 

Could be clutch also, I know they stink pretty bad.

 

does it smell a little bit like burnt rubber? if so mine and my mothers make the same smell after i drive them.

 

Maybe burning the clutch a tiny bit?

 

I get that same smell and I have an auto. I have switched gases from BP to Shell and even switched out my air filter. I still get it. Maybe it is the carbon burning off.

 

It's more in line with carbon burning off. Remember, these cars run a little rich.

 

I have been noticing that the last couple times I've had the car out as well. Hopefully it is just carbon burning off and not anything serious. When I was driving the car everyday though I never got that smell. Now that it sits most of the week I'm getting it

 

Yup, I notice it if I don't go on the highway for a few days then wind through the gears; if I go through the gears every or every other day it tends to clear it out in small enough quantities that there's not enough for an odor.

 

*sniff* AHHHHHH. carbon. the pleasing aroma of destroying the ozone layer.

 

The first time I can say that I noticed That faint yet "positively there" & "new" smell was immediately after putting my first UNDERSIZED s/c pulley on; and it WAS immediately. More pressure , car w/ a few un-assisted miles == that smell . PROPERLY installed an oil catch can (at that time as most of their other stuff I found out;a certain "popular vendors" install instructions were TOTALLY wrong) and VOILA !! GONE !! Just as fast as it had come--I STRONGLY reccomend the purchase (if you do) from one of our NOTABLE "small" vendors. NOT the "Mini wally" You'll be VERY pleased. OBEY

 

Thanks guys, glad its not just me! Its def not a burning rubber smell (I've had that smell before which = bad clutch on different car). Its more of a rich oil scent. I can live with it, just wondering if i need anything checked.

 

Off topic, but while on this road trip, while trying to pass a semi on a single lane road, my wife accidentally dropped the gear into 2nd instead of 4th!!! Just for a brief 1/2 sec and the revs never got past redline. Scared the sh*t out of me though... We were going around 50mph, maybe less.

 

Well Since your not gonna do the OCC route~~~just clean our your intake hose & intercooler & horns~~~~they HAVE oil in them~~~cookin~~~~~~~~~ OBEY

 

If the engine didnt blow up right then and there then you are probably fine.

 

I went from 3rd to 2nd once at about 75 or 80 (my old car), my face nearly went through the windshield and I think I heard a small furry mammal be inhaled through my injen intake. Y'know, I just got to thinking... I never did find the rev limiter in 3rd in that car...
Either way, I hit both the fuel cut (7250) and spark cut (8000), was "pleasantly" notified of my error by the engine computer performing aforementioned things, and drove on with some butterflies in my stomach. car didn't seem to run any different after.

 

if your car didnt pass redline then its all good. 50mph in 2nd gear i dont beleive will even make you pass redline if you release the clutch all the way. 2nd gear redline is usually around 65 mph or so.

 

Good to know that 2nd goes to 65mph... My wife was driving and my first reaction wasn't to look at the RPMs.. I glanced once I figured out what that sound was, but I never got a good look.

 

at the risk of redirecting the thread to the OP question...

nope - I do not think that is normal...

I only say this because I have never ever smelled anything odd at any time with my '04 S. Not putting around, not at speed, and not during or after competition.

If I were smelling anything, I would be looking hard for the source of that odor.

Sincerely,

Charlie

 

thanks guys, I have been wondering since I got the car if this was normal, and just found this thread!

 

if your s/c belt is slipping it will give a nice rubber burning stink when accelerating hard .

 

if your s/c belt is slipping it will give a nice rubber burning stink when accelerating hard .get it up to about 5 grand and floor it from there . if you get the stink of rubber it's the belt .

 

ill have to check that, thanks

 

Actually, after a hard acceleration, it should be more of a heavy sulfur smell. To compare, you would have to be behind someone else that floored it, or you would have to get behind someone going up a steep hill.

If the clutch were at fault, the smell would be more like really hot baked brakes after decelerating hard.
