Default I need help.

Car was running great all day. Long story short i wasn't paying attention to my rpms and i shifted at 7000-7500rpm (the revv limiter kicked in) Now it sounds like its knocking. It drove perfect until i got home. The car is bone stock.

Get a compression check, drop your oil and look for bearing material.

There is nothing to check. Its toast. There is no mistaking that "clatter". Your engine is coming out. Sorry

It's done. Couple questions out of morbid curiosity:

* How far were you off from the full mark on the dipstick?
* What brand of oil?
* How many miles on the engine?

You shouldn't have been over redline unless you mis-shifted down instead of up a gear.

Anyway - I agree - sounds like rod knock. Don't drive it - drain the oil and look for bearing debris. Hopefully, if it is a spun bearing you only need a short block (and some little bits - oil cooler, etc.) - if its a spun bearing and you drive it, you are looking at damaging the turbo and heads, as well. What car is it? Is it covered by the class action suit?

So now that you know you have, at minimum, a spun rod bearing, you have three choices:

Tow or drive it to Subaru, after removing any Cobb AccessPort tunes, and if you are under 100k miles the class action suit extended your warranty and they should fix it.

Call IAG and live your best life with all of that built motor goodness. $$$

Sell it

Personally I would pull the timing cover for shots and giggles. That sound can also relate to a loose tensioner. I had my tensioner bolt snap a few years back, everyone thought rod knock from the sound but I checked everything and the oil looked great, pressure was on point but it had a nasty sound at and just above idle.

If its rod knock you will be pulling a lot more parts off so might as well start with this IMO.

Did you downshift at 7k rpms or did you up shift?

If you up shifted at rev limited that should not damage your eng, that is why there is a rev limiter, unless you had low oil, or low oil pressure.

Now if you downshifted at 7k, well then yha, sorry for the eng.

Before you freak out take a look at loss plastic panels, and the metal heat shields around the turbo, up-pipe, crossover pipe.
