The po of my YJ 2.5 decided to put in a cai I think they stole off a civic. I believe this may be the culprit in my blow by oil issues as the just tossed a breather on the valve cover to air filter box vac hose.. Which blows oil vapor out. Anyone one know if any other air boxes (Cherokee maybe?) that can bolt in to replace my hot air intake and possibly fix this issue?

Put a nipple on the tube and put the vacuum line on that. Most CAI have a nipple so you can put the crank breather hose there

AFAIK the cherokee air boxes won't fit a YJ. You'll need to find a stock set up for a YJ with your engine type. I have seen some TJ guys run an air box off a minivan and route the air intake into the cowl for a more true cold air intake.





And here's a write up on it: http://www.jeepforum.com/forum/f9/wi...ntake-1064377/

+1

Spectre brand CAIs are available at OReilly, etc, have a kit with some grommets and nipples for this exact purpose:

Make sure you have the suction side supplying vacuum to the front fitting and then filtered air intakes at the rear.

Thanks for the help all hooked up right now. Now I'm dripping some oil from under the engine.. Have to check to see where it's coming from.
If I remove the oil cap while engine is running it is still puffing air/smoke from the valve cover. Too much oil pressure? Not sure yet.. But I did replace the sending unit recently.

its blow by... As in the combustion process is getting past the rings. Running without a vacuum hooked up will cause the rings not to seat as well. Give it a week or two of driving and recheck..

Is there anything I can add to slow the oil down a bit? We are talking more than a drop or two.

You can add new valve cover gasket and oil pan gasket.

On a serious note, we need to know where the oil is coming from. It may be from the base of the distributor, the valve cover (most likely if you had an over-pressure issue) or the oil pan gasket, or the rear mainsel, or. or. or.

Clean off the old oil and run it for a few minutes and then shut it off and inspect the block for where the oil is coming from.

Looks like my dipstick popped up. Not 100% I reseated it, almost sure I had it in before leaving for work (30 min. on the highway). I don't have any noticeable exhaust smoke. Valve cover could be leaking because I was hesitant to replace the gasket until I had my issues sorted out. So I suppose it could be coming from there.
Most of the oil on the ground is on the passenger side either looks to be coming from dipstick, valve cover or sending unit from what I can tell. Before I had the ccv setup properly I had a hose from the dipstick tube running up to the fresh air inlet. Then I put a breather in place of the oil cap. I had Zero leaking but to blew a good amount of smoke out of the breather.
I'll drive it home wipe it off then run it to look to see where it's coming from, like suggested.
