Whats the plan on that?

Unfortunately, I'm not 100% sure.

The scoring is minimal, really. I'm talking with a few shops / people who have built these up and then i'll decide what the plan is.

Update -

I Decided that based on time requirements, and the fact that i have a few events coming up at the end of the month, that buying a used engine and swapping it in right now is the best option.

I picked up a engine out of a car that was rear ended and totalled with about 8,000 miles on it for $3300 shipped to my door.

I don't feel comfortable replacing pistons, rods, etc without doing a ton more research or talking to people who have, and I just don't want to miss events because of that. Plus, the most reputable machine shop in our area is backed up two solid weeks, so boring or honing my block would take forever.

So, i am going to tear down my engine completely, remove pistons and really inspect, and then build it back up over the summer / fall. Will go with the flex fuel kit until then so i can run e85 and avoid this damn detonation again.

i didn't have any codes with mine, just smoke .. happened on the delicious e85 ff tune. I've learned my lesson, its much better to have a local "good" tuner tune your car than etune. I ended up grabbing a used built motor.

Going back and thinking about your situation more - it's odd that oil got to your intake if you have catch cans.] Do you have them on BOTH crank and PCV?

the only other way would be if your Supercharger Leaked it's oil into the intake.

My leakdown shows that air makes it to the PCV and Crank, but the cans prevented any from getting into my intake, as both the intercooler and throttle body were clean.

the only code i ever had was misfire cyl 4. When the CEL flashed at me while going WOT, it just flashing intensely and then went away, leaving no codes.

And the weird thing is cyl 1 is the one that popped oil, not 4.

Odd..

the one for the pcv was overfull with oil.. so much that it went past and back into the intake pipe on the sprintex kit..

yes I had a dual catch can setup for both sides..

Was yours a 2013 FRS as well?

Why do 99% of these catastrophic engine failures come from 2013 twins? Is it because there are more higher mileage specimens or is it something else?

Was there any oil in the crankcase catch can as well?

My 13 only has 11k on it.

I had 24k miles

I wonder if it's related to the AVCS issues these cars had early on. The re-flash made the ECU less prone to throwing a code due to cam timing issues, but that's really just masking an underlying hardware issue. If you notice, there were some tuners who reported losing control over cam timing/AVCS intermittently on some cars.

Perhaps there was a quality control issue that got fixed on the assembly line (or on the supply-side) after 2013.
