stock airbox hose
How much oil should blow through the hose coming off the stock airbox you know the one that goes to nothing? I drove my car last night and got a lot of oil mist on the under tray and steering arm on the passenger side of the car . I traced it to this hose area. my turbos work fine and boost 10-8-10. is this a sign of secondary turbo failure??

That's just weird. Are you sure it's coming from that hose and not somewhere else? That should just be a relief for the air pump, and the air pump system is closed off from the rest of the system. Also, oil doesn't tend to back up to the air box - not ruling it out, but it's pretty uncommon there.

Hey Dale. its funny it only happens when I boost the car up to 10 psi on the Freeway for some spirited driving to burn the carbon out as recommended. my car sits in the garage a lot . could this be the problem. possible oil setteling from sitting for a long period?

you guys are right. Thanks for the help. put the car on jacks to check further and it looks like its a thick rubber hose with a metal joint running from the drivers side across the lower portion of the radiator to the passenger side below the airbox. even the bottom of the airbox has oil on it. "is this the OMP line" or "something to do with the power steering" I am going to take the belly pan off tomorrow and check further. Is this an easy fix or should I take it to a shop

I believe that thick rubber hose under the airbox you are talking about is the upper radiator hose?? correct me if i'm wrong, but that should not be the source of your oil leak. The OMP is the Oil Metering Pump equipped on our cars to inject oil into the rotor housings to lubricate the rotors. You probably will not see the the OMP lines unless you remove the air box, they are plastic and are prone to breaking. If you manage to determine that the OMP lines are at fault, depending on your DIY knowledge I'd say this is a good amount of work. You will have to remove a good amount of parts out of the car / engine etc.. There are stainless steel OMP lines sold in various places that aim at replacing those stock brittle plastic lines.
Hope that helps.

Hey White RX7 its not the radiator hose. its a black hose that runs across the lower portion of the radiator to the passenger side below the airbox. I think its the oil line or oil cooler lines. I'll know more when I remove the belly pan. it might be a hose clamp or a snap ring thats loose.

EDIT: N/M... I see you have an automatic...
Could it be tranny fluid?

okay guys...heres the deal. i pulled the belly pan off and saw some thick, gooey oil all over the belly pan. i checked all of the hoses and could not locate a specific leak. this may be what happened...a couple of weeks ago, i went and had my a/c system checked for leaks. the guy pressure tested the system and said that the compressor seals are gone. i think this oily substance may have blown from the air compressor and lower a/c compressor hose and is now oozing down on the body frame. i cleaned everything off underneath and i'm going to let it sit overnight. i'll check tomorrow and see if anything starts to drip. the substance is clear, sticky with an oily texture. does this sound like the a/c testing fluid???

ok open your air box and c if there is oil in there . if there is its b/c you have pressure building in your crankcase and it vents to the inlet of your primary turbo witch is boosting it back into teh engine and when your blow off valve opens its shooting it into the airbox. the path of least resistance in the airbox is THAT OPEN HOSE THAT LEADS TO NOWHERE. of this is the case, you need to put an oil catch can.

Hey trini / dgeesaman/ cantgostrait/ . Thanks for the replys. I am going to check further on my days off and look for leaks. based on the oil substance I found I think it may be the a/c charging oil they tested the system with. I'll post back when I get more Info
Thanks

You shouldn't need the whole system - replace the damaged line with new Orings, have the system pulled to a vacuum and recharged, and you should be good to go.

Hey Dale. I know the compressor seals are leaking big time thats what blew the oil all over the engine bay so I'll need to replace the compressor. while their in there I should replace the high and low side lines along with the condensor and dryer. then the system will be in top condition. let me know if you can locate these parts. I checked out you site ClubRx.org lots of good info their with (DIY) pics keep up the good work.
Thanks
