I ran my vent tube behind a pushrod cover down and over to the left side of the oil cooler cover.

Ran mine to the ground, made my own breather bolts too as there were none long enough at the time for AN Big Suckers

I used the Drag Specialties kit with the DS Dragtron Air Cleaner.

I haven't noticed an MPG boost but you can see why these help so much. The second oily pic was only at 5K miles.

sorry the files are huge

Only thing I can think is that now you are just venting, before the intake was actually sucking gunk out of your engine.

Never liked the idea of blowing muck into my intake.

If you will email us some pics of your setup, we can make better suggestions for you as there may be a few different options you could use, just can't really say for sure.
