My 2012 SI has been diagnosed as an oil burner - about 1 quart of oil per 800 miles! The issue has been recognized by Honda and requires replacement of the pistons and rings. Its a real pain in the *** and a big disappointment in the quality of Honda. I am currently in the process of "negotiating" with Honda, as I am not very satisfied with the dealer (quality of service work has been horrible) or the absolute minimum repair they are suggesting (for example, they won't replace the bottom end bearings, won't consider upgraded parts if I pay the difference, etc). Longer term I want to go turbo and will likely build an engine for that. I have been building performance engines as a serious hobby for over 20 years - so you can imagine my issues in this situation!
I get the reason why they won't allow internal aftermarket parts, as they still have to warranty the engine after the repair. I'm furious about the prospect of them only replacing the pistons and rings and not just swapping in a short block, or as you have stated, replacing the bearings. (and also the oil pump in my opinion.)
And yup, I'm a guzzler.. yet I'm right on the border of what they will not argue over whether it's excessive or not. Just changed my oil last Saturday, I've put 400 miles on the car checked it today and was down a third of a quart. Bitter. My 06 8th gen did not burn a SINGLE DROP. I'm going to have a harder road than most with this, as I bought mine used with 6k on it.
BTW Hondata Flash Pro + VitViper NA Ultimate e-tune bundle for sale. ($675 picked up or + shipping cost, PM me or wait until I post a thread in Xentrader and link to it in my sig.) I'll make a great deal considering that I can't flash the ECU until I am done fighting this, repairing the engine and then probably for 10-20k miles after that to make sure it does not re-occur and to make sure that no other issues related to the work that was done arise. Sigh. I short block assembly replacement would make me feel so much better.
