Ive found quite a bit of info with searches throughout the forum.
For that reason, I didn't want to start an entirely new thread.
I figured I could ask here since my questions are in line with this topic.
Ive got the AC pictured below. It has "ears" on it that block the bolts/holes that the vent systems connect to.
I thought it'd be necessary to get the DK until I checked that.
Anybody have any idea how I could vent my TB with this AC?
When I pull the filter off, the throttle body has quite the coating of oil.
Speaking of oil, when I check mine, its at the "Full Hot" line with the engine cold.
Does that mean its overfull, and could be contributing to the oil in the TB?
Im asking because it looks like oil is making its way onto my engine between my push tubes onto the wrinkle black.
How do I clean that off without discoloring or damaging the finish?
Appreciate the help fellas and ladies.

Just did mine the other day...DK needed to make me a custom kit. Hid mine right behind the A/C.

That's odd, I emailed them a while ago told them I have a Screaming eagle AC. Sent them a picture of the AC, and backing plate. They said they do not make one for that AC. No mention at all about custom, making one...

I did mine a little differently. Drilled and tapped the SE backing plate like everyone, but then tee'd it and ran a hose back between the motor and tranny down to the frame. No need for a filter, it would just collect oil and dirt. There is no back draft to the motor because the breathers have one way valves.
I think it's pretty un-noticable and am looking forward to cleaner combustion air and no oil drip. Just needs to stop raining...
ps while I had it out I polished the backing plate where you can see it.

here are pics of my ventilator mod. you can see the orange high temp silicone in the holes. Not all breather backplates are the same though.

SE Ventilator cause I like the way it looks and I already have it installed. With the K&N filter, flows 287CFM which is fine for the heads I have which flow 252CFM
(2) Dorman 785-410 1/8" MNPT - 1/4" hose fitting (advanced auto)
(10') 1/4" vacuum line (advanced auto) yep plenty left over.
(1) 1/4" vacuum hose "T" (advanced auto)
(1) 1/4" to 3/8" vacuum hose adapter (advanced auto)
(1) Spectre 3991 Breather Filter (advanced auto) http://shop.advanceautoparts.com/p/s...m=spectre+3991
total - $15.49
took the backplate and drilled 25/64" holes in it
Then I used a tap, M10x1.25 to thread the holes
Then I cleaned the breather holes and oil drain holes thoroughly with brake cleaner
Then I siliconed the oil drain holes that go back into air intake (yep that was the only color hi-temp/oil resistant silicone I had on hand.
Then I screwed in the fittings, attached hoses, attached clamps, inserted "T" in proper location, ran the hose inside the front pushrod tubes, and located the filter just behind my oil cooler and fastened in place with a zip tie. The "wetness" you see in that last pic is from my cam change a couple of days prior to this mod.
all said and done, $16 in parts and about 45 minutes of my time that will prolong the life of my motor.
Thanks NutZ!
