so recentley I've gotten a smell from my toyotas engine....ill admit i drive my car hard and by hard i mean i love to accelerate a lot.. but i have noticed that overtime i come from a short or long drive there is this present smell that smells of burning rubber....and i have never smelled this until i hit 8k miles... the only upgrades i have to my engine are a short ram intake but i installed that at 7k miles and it has a heat shield...the smell seems to rise from the bottom of the engine up...any ideas? I'm going to try driving with ought my short ram to see if its that...or I'm going to toyota because i mean if it was my hard driving that caused it..why would they add a Sport button????
