new car engine rust
I recently bought a 2012 WRX sedan with 900 miles on it. Snooped around the engine just to get familiar with my new toy and i noticed rust buildup around the flange where the turbo connects to the downpipe. I know this is normal for new cars (but still concerning to see on a new car!) to already have engine rust but what I am wondering is if the rust will eat through or if Subaru puts some kind of protectant for engine rust. Gonna use WD-40 and wire brush to scrape it off, but also wondering what some of you out there use to clean your engines.
