rough idle and burning oil

Just got my car back for this issue and would like to share my experience. Hope it helps someone going through the same issue:
2006 GS300, no CSP letter.
Second owner, car had upwards of 190k on it. I noticed my oil consumption was getting progressively worse and got to a point where I was burning 1Qt/400 miles. I researched the heck of out of the rough idle CSP before going to the dealer.
Brought my car in, upon diagnosis my piston rings are fried. They could see it burning oil in idle. However, my car was idling nice and steady. Recommended I do an oil consumption test and bring back in 1200 miles.
Brought car back after 400 miles, down 1 quart. I told them there is no way I could wait 1200 miles. Confirm oil consumption. Idle still steady. Top off oil and ask me to bring back in a week.
Bring e car in again, still nothing. It was pretty cold out the past couple days, and. I did see r idle bouncing around a bit. They were trying to recreate, but it needed to occur long enough for their computers to capture it. Asked to keep car overnight.
Next day, still no resolution. I pick my car up and asked to bring it back in a couple weeks.
At this point, I bring it back, but we contact higher level management. They are willing to help, but need to do another oil consumption test. I agree and bring back the car after a week or so.
Get the car approved for repair under the CSP. They highly recommended I change out the spark plugs, motor/tranny mounts, do a rear differential service, and change out my filters. I give them the green light. No labor charges since the engine will be out. Came out to just under $1k.
They find out that my block is scarred from the bad piston rings. Instead of just replacing rings, they also give me a whole new engine block. $7500 retail.
After about 500 miles, runs like a dream. Engine is much smoother/tighter feeling, gas mileage has increased (before getting around 20mpg, now 24mpg) and no oil consumption.
I would highly recommend finding the best service tech at your local dealership and take care of him. These are the guys going up to bat for you when it comes to getting these CSPs approved.

Can you please let me know which dealer you went to for this? I have the exact same issue - my cylinder walls are scarred causing loss of compression. I burn a qt every 100 miles or so, and have awful smoking issues. Cat's are clogging and the car runs like crap. All this is after the pistons and rings were replaced - the dealer wants to charge me $13k for a new block. I would love to hear your thoughts on the process with your dealer as well as how you were able to get them to rectify the situation. Lexus Corporate Customer Care has been less than helpful as well.
thanks,
Ryan

I have a 2006 IS 350 with excessive oil consumption. Started noticing at about 90,000 miles, with 1 qt added after 2500 miles. Now up to 118,000 miles & now needs 1 qt very 1000 miles. Noticed blue smoke from exhaust on cold startup...Does anyone have any suggestions? (Note this is NOT a 250). Thanks!

Oil
New to the club, signed up because looking for info on my "new" used GS. Have it a few months and it was fine. Now i am getting check engine light and a stumble every now and then. I also used a quart of oil the last 1000 miles. The car only has 70k on it and it was a one owner, dealer maintained car. Anyone point me in the right direction? freaking out. Also live on Long Island, who would you trust to look at it.
Thanks
Thanks

I've been using amsoil in the car for the last several years, I have no idea if it makes any difference or not I just use it so I don't have to worry about the oil for a year - I only drive like 2,000 miles a year anyway. If it is burning oil I will probably never know.
So I think I'm out of luck on getting the rings done on my car... I try not to worry about it too much since it seems fine but I would have greater peace of mind if I could just get the work done... my car will have been in service for 9 years as of September I think so that's the end of the line for this car ever getting that service done.

so I have an 06 gs300
I recently took it in about a month ago to get it serviced for the misfire so they replaced my pistons or whatever, whatever it got recalled for
Today I noticed that my oil maintenance lit up, (changed my oil like 2-3k miles ago....) and I have been noticing some rough idling, but I kinda ignored it.
Should I really be concerned? I'm gonna call Lexus tomorrow to see what the deal is.

Not every one will have this problem. Long story short: if your oil light comes on between oil changes then you have a problem. What will usually happen is the dealer will top off to proper level then mark the dipsyick and ask you to drive 1000 miles and return so that they can check the level against the mark. This is verification of excessive oil consumption.
The other issues are related to engine codes coupled with rough running/idle. If you have either of these then a dealer visit to get the ball rolling is in your best interest. Reports are that many are getting this done at no cost to them. You won't know until you try.

i'm burning through 1.5-2 quarts of oil in 1000 miles. i went to the rallye lexus dealership to have the excessive oil consumption test done. they returned my car after a few days and told me it's a cracked timing case cover and that it'll cost $3000 to repair. so i went to an independent mechanic and he said there's no cracks on the timing case cover. if there was then the area all around the front of the engine would be covered in oil at the rate of consumption my engine is doing. he told me i need to call lexus corporate and really try to argue my case. has anyone else had this same problem and had to fight lexus to do it with success?
my car has just over 135k miles right now

The reason I got a Lexus and not a BMW/Benz/Audi was to drive my car for 200K plus and NOT have massive service issues like this.

Hi Guys,
I am new here so hello to everyone
I am thinking to buy GS300 2006-2007 but I see that many people have got issues with this engine. I wanted to ask you if it was finally fixed somehow by Lexus ? Does it affect only 2006 models or 2007-2008 can have exactly the same issue ? If there is some new version of this engine, free of those problems, how can I evetually recognise the new type of engine ?
Thank you guys for any opinions.
Cheers!
