New pistons and rings sub 20k

[32bitsofGil]

Its very rarely the tech for this level of work, the people doing this work are generally very experienced and capable. They know what is wrong and what it needs, they do this shit all day every day. Its always management pinching pennies. They probably hopped they could get away with a cheap fix instead of just doing it fucking right the first time.

To be very honest I believe Toyota is at fault for writing a service bulletin with these procedures. I think not many owners have had to make it as far as I did down that decision tree.

I do wish they would opt to replace the long block first and try and rebuild potentially save-able engines to recoup the cost difference of rebuilding at the dealer. It’s not needed for every engine, but these specific 2021 early builds are known to have this issue.

I place little to no blame on the dealership, who in good faith offered to buy me out even with a six month estimate on repairs.

Well to add to this discussion. I have a 2020 3.0 w/10K mileage and going in today for an oil consumption test (actually recommended by the dealer servicer). Less than two weeks ago I had the brake recall done. I guess they failed to conduct the standard 100+ point inspection because yesterday the car told me I was at minimum engine oil and to add 1 quart. Reading these posts I'm not sure what to think it could be, hopefully not worst case. No suspected leaks as the previous owner requested an inspection for leaks in June of this year during the last oil change with nothing found (previous MX log from dealership). Additionally, there are no oil spots in the driveway. I'll update later today after the MX appointment.

Unfortunately, I don’t really have any updates as I haven’t really been driving it much due to the weather. I’m in the middle of my 1000 mile part 2 of the oil consumption test and I’m sitting at 600 miles due to bad weather and summer tires. ?

I'm ignorant when it comes to the process/parts of the test. I was thinking through how the dealer would conduct the test and nothing really made sense to me. I guess I should just use google.

The part that sucks about this situation is having that nagging thought about the outcome in the back of your head. I'll admit I don't have patients when it comes to this crap while making monthly payments. In the past I haven't kept cars more then 24-36 months (should have been leasing throughout my adult life. Just shitting tax/fees down the drain). As a result, I've never had any car issues (BMW, Honda, Dodge, Jeep, Mitsubishi), with one exception Audi... I really enjoyed the car but I got rid of it because mechanically it was a piece of shit. I truly hope this isn't the case here.

So that's where we are, Toyota just told me that I need new pistons and rings and I'm still under 20k miles on the car. I was dealing with the oil consumption issue so they advised an oil consumption test. Results were, down 2 quarts after 2500 miles. Their prognosis, new pistons and rings. Sound about right?

From what I gathered from different brands, this piston rings replacement are not uncommon and quite wide spread. It's party due to the EPA CAFE (higher MPG cars required) mandate, causing manufacturers to go w/ low-tension rings (oil scrapers and compression). I wouldn't be surprised if they got you a standard set of rings to keep the combustion free of oil and properly holding the pressure.

Update on this:

Toyota just agreed to rebuild the engine. Car is gonna be down a month, longest portion is waiting for parts so could be longer.

Update to this: Toyota is still waiting on parts, so they gave me the option to enact my state's Lemon laws. So they gave me a couple options:

1. Car Buyback
2. Same year/model replacement

I really don't want to do another '21 to avoid the risk of having this oil consumption issue with the replacement, but if they replaced it with a newer model, I'd be ok with that outcome. What would you do?

 

[Traxion]

I'd do a car buyback and then find a 2023 model since it has the newest revision of suspension.

That's actually a good idea, I've been shopping and I see that prices aren't too high for premiums (not interested in a A91) but I may just go this route. Thanks for the suggestion!

 

[FuzzyRev]

Same year/model replacement is what I'd do. The risk of another bad engine is very low.

If you still want a Supra platform then I’d do a replacement

I bought the car because I wanted a Supra with the intentions of modding it, I wanted a fast turbo car, that wasn't going to break my common man pockets. I know there are other options, but in this range for it's performance, I'm not sure of any other cars that would compare at the same price point.

I was just verifying that you did still want a Supra. Nothing wrong with that

Toyota techs are gonna rebuild your BMW motor??!! Nooooo! Ask for either,a complete motor or at least an assembled short block!
Rebuilding a motor that needed piston and rings because of oil consumption?! Do you actually trust the Toyota techs to properly
Hone cylinder and set ring gap?! …ask for a
Crate motor or at least a short block which was assembled by BMW techs in Germany!

Agree with that. At the very least the cylinders will need a flex hone run through them and I don't trust a dealer tech to do this correctly or much of anything else involved for that matter. On the Focus RS forum for the head gasket recall some cars also required a new cylinder head. Owners were hoping they got a new head as well which I told them was the last thing they needed. So in many many cases the techs just unboxed the new head and transferred the cams and lifter buckets over into the new head in the same location. Valve clearances checked you may ask, well when Ford allocate an extra 45min labour for the new head and the cams and buckets need to be fitted to check the clearances and then removed again to replace/swap buckets around and then install the cams and re check and maybe even new buckets ordered how do you think that process went. Rattily engines and or burned valves and poor performance was the order of the day.
Dealer techs for invasive engine work....no thanks. I honestly believe that if any engine needs this degree of intervention then just get rid of the car and buy another new one. Thats what I did with the RS. Wasn't going to have any Ford tech stripping my engine down.
I've actually been personally involved in a few serious engine manufacturing issues and often the factory sends a "team" of techs on a world wide campaign with all the tooling and parts and set themselves up and the affected machines roll in and are done fast and efficiently by experts that really know their stuff. Doesn't apply here of course but for multiple big issues the good factories don't let dealer techs get involved.
