there is no flap, it is an open hole mostly covered by the plug
they can arrive off the boat clogged sometimes
(anti corrosion from factory which was the rav4 problem)
the plugs do reduce noise, open them all up you'll get
some degree of wind and road noise amplified in the empty
clamshell of the door.
doors are built to get wet inside, but also they need to drain
and not hold water
you can't put a catch can on this motor, there is no way to intercept crankcase gasses unless you design and build your own manifold. it is all integrated into the manifold and has it's own embedded oil separator system. the one hose that goes to the airbox is pressure balancer NOT crankcase...
I just checked all around mine and they are tight but have little gaps behind
them and drain just fine. dry as a bone and we've had a metric F-ton of rain recently
(plus numerous touch free carwashes)
ha I do better than that...total loss oil system
55 gal drum of oil on the roof, gravity feed
the oil intake, oil drain plug is open and dumps to giant
oil diaper I strap to the frame.
every component gets the freshest juice available
just saving receipts would be good enough imho. any reasonable person can see if you are buying 6 quarts of 0-20 and a filter on a periodic basis, or enough to do oil changes on a regular basis...you ain't just throwing it away trying to scam anyone.
imho amber works but is too dark
you need yellow if you want max visibility in dust/rain/snow
yellow cuts thru rain, fog, and dust best, amber is ehh, ok but is dimmer/darker
dust is what you will see the most of driving around on unpaved roads
the specific yellow frequency that stickerfab...
