Does anyone have good pics and instructions on how to do this mod

do you want aptmosphere dump or a closed system? kause most just turn the dog house on the valve cover around, and run some hose to behind the cab and dump it.

I did a closed system. I've ran it for over 6 months and over 6000 miles, and no problems, and keeps most of the oil out! I recently removed my turbo for a fuel system upgrade, and noticed there were small traces of oil in the boots, but this is normal, and the best part was there was 0 seepage! The only problem is that you'd have to take a trip to Home Depot/OSH and the local Parker shop. I'm not sure how much the filter canisters cost, since I got mine from a waste bin. The cotton string woven filter elements really work well though.

Open loop systems stink up any area you idle in, and you have to be very careful not to have any dips in the hose, otherwise oil collection will occur, restricting vapor flow. We all know that pressure is bad for CCV systems! I thought closed would be a good idea because the open setup has the smell problem, dripping oil on friend's driveways, and the closed system offers a vacuum for the CCV vapors, instead of it going to atmosphere.

Here is my setup:

I've got the open system and don't have any complaints. I ran mine out in front of the rear axle.

Do yourself a favor and replace the o-rings on the CCV housing while you are doing the swap.

I also turned my CCV housing to make it easier to route the hose. The housing is the same both ways.

Here is some pictures.

I set mine up like my drag car and hooked it up to the exhaust. They say its 15hp on a race engine. I don't think thats the case here. I just had every thing off the topof mine and there is no oil.

What did you do in the last 2 pics? Did you plug the hole?

I cut the tube sticking up in the inside of the connector and put a hard plastic cap over the outside with a hose clamp to hold it on. The cap went on VERY tight, but the hose clamp was for extra precaution.

Where did you find that cap at? I have the same style intake and when I did the CCV mod, the only caps I could find were some thin rubber ones from McMaster Carr.

I got it at the local O'Reilly Auto Parts. It came in a pack of other caps.

Ok, thanks. I've been meaning to do it but I can't find the time. Now that it stays daylight longer, maybe I'll be able to get something done.
