My First Mod!
Last year, I got inspired by this forum and decided to clean my MAF and throttle body, and replace my PCV valve/grommet. Went without issue, neither was particularly dirty, though not pristine, but I remember wondering where the TB crap came from in the first place.
Fast forward to a few weeks ago. In a forum thread here, I saw something mentioned called a "oil catch can'. I'd never heard of it, so I watched a few YouTube videos and then realized (duh!) that all the black gunk I'd seen in the throttle body was coming from the recirculated fumes pulled back into the engine via the PCV valve. Eureka!
This led me to ebay where I forked out $15 for my first official 4Runner mod: a red oil catch can.
I hunted around for a spot to mount it, and settled on the side of the air filter box. Drilled two holes and positioned the catch can to be a little lower than the PCV valve, so any oil would run downhill to be captured. To keep the oil can from rattling in its bracket, I threaded a section of old bicycle innertube around the bracket and tighted it up.
Drove it 5 miles today, and the 4Runner didn't catch fire -- so I think I'm good to go.
