Senior driven 430, now me. Carbon build up or needs a motor?
Heres the deal, about 3 weeks ago I picked up my LS430. 02 and does have 183k miles on it. Older gentleman owned it before me since day one.
During my test drive he said I had a heavy foot (and I was just doing over a 1/4 throttle) LOL.
Well today I noticed I gave it about 80% throttle at higher speeds (Was in the HOV lane where those speeds are allowed) and once I let off, I noticed a ton of smoke & back bumper had a ton of residue on it.
The original owner had it maintained at the local Lexus dealership every since 5000 miles as recommended and even the service writer I deal with confirmed that. Car was not beat on at all and was maintained.
Just curious, has anyone ever dealt with a similar situation possibly? I changed the oil last week and the oil level did not move after this incident happened. And now back to normal driving, it's perfectly fine.
So your opinion... carbon build up or needs a new motor?

Sounds like carbon getting released, just a guess but, most older people don't rush along like that(We all can do this a little more to be honest in general), they take there time driving because there not in a rush. our car for the most part probably hasn't been pushed as much as the next car has so, they smoke was probably a build up release. If it was still occurring everyday, I'd be concerned but, clearly as you drove it went away.
The person who owned the car probably never went over 60 mph., so the car hasnt been driven rough at all!!! Just a guess, if really concerned take it to the dealer or a experienced mechanic and have it diagnosed for the peace of mind. I dont think its a serious issue nor an issue at all fellow member!!!!

2001 LS430 Mark Lev/Navigation,Black Cherry (exterior) Ecru (interior) with golden birdseye wood/woodkit to match. Australian sheepskin seatcovers 1inch thick.Sheepskin Seatcovers.
If your oil is clear, maintenance record is good and up to par, then I would not worry about it. Black smoke in the beginning with no other signs of engine failure then it's just carbon being blown just drive it and enjoy. Cars now born again new...
