Not to start a debate over this mod or not .....but....
someone I know said that the vapor from the crankcase is routed back into the intake to give the turbo intake bearing lubrication .
What are your thoughts about this ??

Either way CLEAN the doghouse!!
LMAO Sorry but that is so far off base I can't help but to laugh. If you follow that line of thinking oil from the compressor wheel would get to the bearing...And how since there is a seal between the compressor wheel and bearing. If that was true oil from the oil bushing/ bearing would be able to flow the other way too. And that is NOT suppose to happen. So the answer is NO that is not true.

Maybe I should add a doghouse gauge like Joe. That way I can keep an eye on it... Sorry joe, I couldn't pass it up.
I still don't quite understand the real issue. Is it just to keep oil from settling in the IC? And will oil in the IC cause failure or reduced efficiency other than possible issues with stock boots? Sorry I'm going all the way back to basics here.

The issue is the oil vapors over time coat the inside of the intercooler, reducing its efficiency. The boots issue can be solved with quality boots over a CCV mod, but nothing can fix those efficiency issues.
I just run mine to vent outside. Its easy, fool proof and causes NO issues.

Joe I agree there is no way that is happening everytime you change oil so hence ccv modd. But cleaning it would help. I am NOT saying clean it every 10k or 5k but I am guessing that if you did you would get next to nothing going back into intake. I knew you had alot of gauges but I didn't know you had a gauge to measure crank case pressure..Cool

I didn't take a good look inside the doghouse while I had mine off, but isn't it just a wad of steel wool-type stuff? I'm thinking its purpose is to give oil vapors somewhere to condense and drip back down into the engine. It's hard to imagine it getting "dirty" or "clogged"; seems like it would be all coated with oil again in the first 20 minutes you ran the motor after you cleaned it.
Mine is turned around, and routed to atmosphere. The hose from it goes uphill, over the brake booster, before going back down and exiting by the frame. I think the uphill run would give vapors even more opportunity to condense and drain back down. I figure that as long as I keep seeing healthy puffs of smoke coming out of the end of my CCV hose, it's not clogged.

Removing it and cleaning it, is like changing your HPO... Does nothing, but cost you time, and money.

I have a question: If it's loaded up with old and sooty oil, wouldn't everything just get sucked through? If it's clean with fresh oil, wouldn't it pass the air and do a better job of dripping the oil back down into the VC? I look at the design and it looks like that was the original intent.
Its not a filter, just a cooling area.
Again, for a bunch of guys who talk about K.I.S.S all the time it just kills me when you worry about thing that are so simple.
