Yeah I should...or maybe I'll get a brz and leave it stock..lol
I feel like blow by wouldn't cause all 4 cylinders to throw codes at once.
On the plus side the vacuum reading on my boost gauge hasn't changed, there is no smoke puffing out of my oil filler( I read that is a sign of bad ringlands) and it hasn't been consuming much oil so I don't think the engine is blowing up just yet lol.
