    After changing my oil I was wiping down my engine cover area since it was dirty. Accidentally knocked this off. What is this? I picked it up and screwed it back on. Do I tighten it as tight as possible when screwing it back on or is it like the oil filter where I do the "3/4 turn"?

    I bought my truck used a few years back and it didn't have a owners manual so I can not reference back, sorry :eek:

    Oh ok, thanks! Thought it was something serious.

    No shit? Where do I get a female end to put on my portable air compressor so I can air them all back up at once instead of one by one after off-roading

    those valves can leak, the cap will slow the leak or stop it. 4runner does it...remove cap, observe bubbles, close cap, don't do it again :D

    Guys, stop being so greedy and be honest with the man! We all know that is the charging valve for the flux capacitor! Anyone know where the cap is for the blinker fluid though? I am having a hard time finding it, and I am a little low on the left front blinker.
