Carbon build up
Hey guys, just dropped off my car at lexus for them to start the week long repair...I'm thinking since they have the engine dismantled, I can have them change a few things while i'm at it. So what do you guys think is good maintenance for an IS250 awd with 110k miles? Spark plugs, belts, water pump, etc. They will only charge me for parts so I want to take advantage of this.

So I went in today for them to look at rough idling issue and oil consumption. They came back after an hour with nothing and sent me back home.
They did though came back to "caution" me that both my CV rear boots need replacing, so basically 2 new rear axles which was going to cause over $2k to fix. Fail.

about the cv "boots" i bet if you look......it's not the boots leaking. it's probably the outer cv joint housing leaking where the two metal parts are pressed together. that's why they quoted two new axles. can't rebuild that part.
So.....ever heard of FIPG?? how about permatex? Get ahold of some good old fashioned BLACK Toyota FIPG. clean the grease off those joints real well with brake clean. make sure the surface is perfectly clean on the CV joints and slap some FIPG on that thing right on the metal seam that's letting grease escape. just smooth it out with your finger all the way around the cv joint and don't drive it for at least 4 hours....
If you don't like the fact that the next guy to work on it might see it and think it looks like total hack work....then go ahead with $2000.00 in axles.

if the engine really has a problem then keep taking it back.

I just had mine done gave it to them for about a week, but my car was still under the power train warranty for another 6months lol. Does anyone know if this new 9year carbon buildup thing is effective in Canada as well?

How do I convince these people at lexus that my excessive oil consumption was due to this carbon build up??
I've been dealing with losing oil for a couple of years now. There answer was that my pcv valve was clogged and that's why I was losing oil. They replaced it twice within two years. Is it common to replace it this often? I remember reading somewhere that one of the issues of the carbon build up besides the misfiring is also excessive oil consumption. I mean what would clog this valve if not from carbon build up and sludge...thanks for the help in advance.

hey there, what exactly did you get done in Canada? I did get the top engine clean under powertrain warranty but they were pretty tight lipped about the extended warranty (to 9 yrs). They might not make it official ever and only deal with it on a case by case basis in Canada...

ok..so i just my letter too..but here's the dilemma. I don't have any problem with the carbon build up, i had a rough idle a while back, but no check engine or any codes pop on the dash 07 with 114k and still running strong....should i still take it to the dealership and get it done or just wait until this really happens to me. I am afraid that if i take to the dealership for the service, something might start acting up... (superstitious) crossing my fingers...
