Engine Problems..
So i took my car in the other day for some minor issue. Turned out to be a bigger issue than i thought. Dealer told me my piston rings were messed up and my hydraulic lifter. Would love for someone to chime in on how this could have happened. Im guessing you have to rebuild the engine? -______-
nd yes i have been on point with my oil changes.
not that it matters but what would you guys say this would cost out of warranty?
3 weeks... nd I'm stuck with a loaner =/

not at all i got that fixed a while ago. Searched all the forums. seems like no1 else seems to have the same issue.
the minor issue was just a blown fuse... i told him i had horrible gas milage so I'm sure that why he checked the engine, i thought i needed a new filter or something.... was i way off!

To fry your piston rings it would have been either oil starvation, but you were on point with your oil changes so it couldnt be that. Or severe over reving the car when the oil is cold, but generally if you overrev that much you would have some valve issues as well.
You dont necessarily have to rebuild your engine just replace the piston rings but that is an expensive job, they have to remove the head, replace the rings and redeck it.
Cost wise, i am guessing over $1500-$2000 at a dealership easily. The parts arent expensive its the labor that is going to murderous.

No. They're saying your problem is related to L-SB-0061-09: 06 IS 250: M.I.L. "ON" DTC P0172 & P0175. This LSB replaces the pistons, rings, Valve Springs, Valve Lash Adjusters, and Valve Spring Retainers (if applicable). They're not saying your pistons or rings are shot, they're saying this is what Lexus says to do to fix your issues.

So are you still under warranty or not? And what are the symptoms/warning signs to watch out for related to this issue? This is the first I've heard of the problem on CL.
I guess I should also ask if this is a 250-only issue or not.

I'm new here so I'm just curious as to what you might be referrIng to?
I ask since my service manager made a comment about some kind of engine noise to watch out for. Thought he said something about the cam guides??? Thanks

If you're still on warranty, watch out for it and have the dealer perform the related tsib.
I recommend you get this done preemptively if you're close to the end of your powertrain warranty. It's about a $1600 fix. You can go to the thread linked above and record on your phone the audio files people have posted of the cranking noise. Then bring it in and tell them you've been experiencing the issue sporadically and they might not be able to replicate it, but you recorded it on your phone so you can play it for them.

TSIBs are copyright and property of Lexus and Lexus charges for access to them, so posting them on a forum like this is illegal/frowned upon. I found this out when I tried to post a PDF of all of them on CL. That said, you will find some of these TSIBs out on the internet and in CL threads.
