I'm really not sure... he told me he had to take my intake off to get to one side of the plugs, that's when he took a quick look to see. I'm no expert, but I would imagine it would be quite costly to have someone check to see how much carbon buildup there is in your motor. Just run seafoam through it and you should be good. I look at it as cheap insurance for my motor.

ooooooooooooooooooooooo!
So some good/bad news for the Carbon Build Up...
Bad news is that the issue was verified again with my car after the new pistons were put in, They sent off the compression test, Leak down test, misfire codes, etc to Lexus Corporate. Unfortunately, Lexus has rejected any further repairs be done at this time based on the results (even tho there was carbon build up and misfires after the pistons had been replaced). Good news? My SA believes that this might mean there is something bigger Lexus is going to do with this issue. I really hope so, because if i'm having issues after the new pistons and my claim was simply rejected for no reason, i'll be pretty upset. I'll be in contact with the service department over the next couple of months or so to see if anything new comes up.....keeping my fingers crossed!

They've had my car for over 2 weeks now I believe for testing. The great thing is that my dealership is genuinely trying to fix the issue. Unfortunately, they are at a block if corporate says no....all i'm hoping is that corporate is holding off on the repairs for a damn good reason. I really love this car and it would be a shame to have to sell it before the warranty is up because there's no good enough fix...

I just sent in my IS250 for the same issue. And I also already had my pistons and rings replaced. I specifically asked about carbon build up prevention.....SOL.....i was told the best was to use premium top tier gas and full synthetic oil....even then it will still happen....kinda upset I paid all this for a defective engine design!

The local dealer is only going to do so much for you. If TSB states that they should have replaced the lower block originally and they didn't, any subsequent labour as a result of the rework would be their cost, I can see them playing the "corporate said no" game to avoid re-doing the work.

Is this the point where you call corporate directly and mention that you are considering consulting a lawyer as well as calling the auto journalist for the local paper to run your story? Given Toyota's recent past, they will do whatever is reasonable to avoid negative publicity.

I did the oil change by myself for the first time and I added fully synthetic oil. I can feel the engine is running more smoothly than before. I think the dealership didn't put synthetic oil on my previous oil change.

I doubt that's going to help since there were already articles/reports from Audi RS4, a vehicle costs 64K+ with the worse problem on engine carbon buildup in the auto journals. Also according to Lexus, the carbon buildup doesn't apply to any safety issues.

I am starting to doubt the truth about his post. He posted on here that he has an 06 250 with 250,000 miles on it with minimal problems. He said he put 250K miles on his car in 5 years doing CITY driving. Taxicabs are the only cars that could possibly put 50k miles per year in city driving. I am calling BS.
