True! I'm just panicking after seeing smoke at my tail pipe because I'm not used to my car not running healthy. But that's true doing both of these tests first should help. I'm just trying to read the signs my car is giving me hoping to determine the issue.
I totally get it, sucks to see smoke like that. But those two tests will really get you headed in the right direction. Usually if it's rings though she will blow smoke under vacuum, like if you get up to speed and down shift the the rpms come up it will suck oil past the rings at that time and blow smoke. At idle like your describing or at a stop light it maybe turbo related. Valve seals usually leak down overnight and you will get a big puff of blue smoke on startup.
