#1 of 14 2004 Lexus 430 Engine problems by mahalo1 Apr 24, 2007 (5:01 pm)
Trying to find out if anyone has had a similar problem. If my car sits for more than a day, when I first start it it makes a loud clattering noise, almosts like collapsed hydraulic lifters, and pours out lots of blue smoke out the exhaust. Its happened 3-4 times over the last 3 years and all I get is dealer bull****, lots of lip service but no repair. I've been told its the buckets over the valve spring hanging up "but its not a big deal or problem". Well it happened again the other day and I'm just tired of the nonsense from the dealer. Has anyone had a similar problem or heard of someone else having this problem, if so please let me know Replies to this message: holew (Apr 29, 2007 8:22 pm) chickenbone (Apr 21, 2008 5:56 pm)

Replying to: mahalo1 (Apr 24, 2007 5:01 pm) I have an 2002 LS430 have had zero problems after 74,000 miles.   My suggestion to you is to take it back to the dealer and explain the problem. May be even do a recording using a digital movie camera with sound to make your point.   I have found that the LEXUS dealers I go to are excellent in diagnosing problems.

#3 of 14 Gas Mileage by jerry5505 Jun 01, 2007 (5:46 am)
Can any one tell me what kind of gas mileage they get on the 2004 LS 430? I am getting approx 17.4 miles per gallon in town using Prem gas. I am wondering if I should have the dealer check it out.

Replying to: jerry5505 (Jun 01, 2007 5:46 am) There's a discussion which will give you some information. It hasn't been posted in for a while, but you still might find it helpful: Lexus LS 430 Real World MPG. Maybe if you repost there, you'll wake some people up!

#6 of 14 LS430 SMOKE by devinsdad Mar 14, 2008 (5:43 am)
Hi! I am new to this forum and appreciate the advice! I have a 2001 LS430 with just over 100k. Occasionally at startup, the exhaust will expel a white-ish blue smoke for about 10 seconds.   Oddly enough, it seems to happen more if I park on an incline with the nose higher that the rear.   Any suggestions would be great!

Replying to: holew (Apr 29, 2007 8:22 pm) I saw your message that was posted about a year ago. Did you ever resolve the problem?
#8 of 14 Smokes when starting by chickenbone Apr 21, 2008 (6:00 pm)
Hello, it does seem to matter when I park with nose down in our driveway vs the nose up. It appears to be more smoke when the is up for about the 10 seconds. Were you ever able to resolve the issue or find out the root cause?
