How much oil does your York OBA compressor spit?

Is that an early 4.0 with no AC? I thought the stock box looked like it would fit on mine!
Is this one of their NEW Made for OBA compressors that isn't suppose to spit as much oil and stuff?

Also I would get something to cover your air chuck as it's going to get filled with dirt and end up not working.
Have you seen these neat nipples for the chuck?

Make sure you know which type of air chuck you have before ordering.

This is a 2003 Rubicon. I still have A/C. ORO sells a relocation bracket for the alternator, which allows it to be dropped under and the YORK on top.
Yes, my York is their upgraded unit with the finned head. It still spat oil out until I attached my filter.
I like those air couplers I might get one. I made my own as a temporary solution, but I've had it this way for almost two years and still holding strong.
Testing the system by just spraying into the air or into a towel for the last few days and i'm only seeing a fine mist of oil coming out.. but today when the wife aired up all 4 tires after a trail-run (the LJ is "her" Jeep) her hands kept getting covered in oil.. i realized that after the previous owner airing up these tires with this compressor for the last few years has probably left the tires full of oil, and that's what's not spitting back out onto her hands..
..so my new question is: whats the best way to 'drain' the tires without having them removed from the rims and wiped out by hand? we will be replacing them soon, but probably not for at least a couple of months..

I'm wondering if the previous owner kept the York system over filled. As it was stated in an earlier post, it only needs about 8 oz. The only way I can see draining the oil from inside the tires without dismounting them, is by putting the Jeep up on high stands and puncturing the tire at the bottom, then plug the hole. However, idk if the plug will stick on an oily puncture.
If it were me, since the oil has been inside the tires for many months and you are going to buy new tires in a few months, would be to leave it alone and deal with it when you change tires. It just seems like too much work for the benefit received.

I just picked up the ORO bracket and a compressor off of E-Bay. The bracket is awesome and everything came together quickly and easily. I'm in the process of plumbing and need some advice. I was planning on running the discharge line as seen in the pics below. Do you think its ok for me to attach the hose to the A/C lines with zip ties? I am fairly sure that the air line will get pretty warm and don't know if that will cause a problem with the A/C lines. There are other alternatives but this appears to be the cleanest installation as far as I can tell.
I used zip ties for mine. One caution, make sure that red hose leading away from youir compressor is rated for high temps. I used a standard air compressor hose and blew a hole through it the first time or two I used it. The air coming right out of the compressor is HOT! I also used as large of an inside diameter hose and fittings as the fitting on the compressor had to maximize its CFM output all the way to the chuck.
I originally installed a small air intake filter likes yours but then just connected it to the air intake tube via a screw-on barbed fitting. You can see it here...

Cool, I just picked up some ContiTech Blue Insta-Grip 300 PSI Push On Air and Water Hose for the system. It's good to 210 degrees. I'll run it as illustrated in the pics above and pray for the best. I think I'll be fine.

What's high temp? Care to direct me in the right direction? I have scoured the internet and everything that I have found shows high temp hoses as being up to 180*. I assumed that 210 was more than enough.
Got a temp gun? Run the compressor a few minutes and shoot the head. Easily over 300 degrees. The brass fittings you have conduct heat very well so it won't take long for the hose to suffer ill effects. There is a reason practically every compressor with any considerable output has a copper outfeed line wrapped in cooling fins and it ain't for looks. You need a section of stainless steel braided line or equivalent off of the compressor head output before it transitions to your plastic air line.
I'm working on a rig right now that has your air line run down the top of the driver's frame rail. It has a big bubble where it blew under pressure right across from the cat. Go look at how far the top of the rail is from the cats if you want to understand what heat does to plastic air lines.

Got it. That's NOT what Jerry said in his post and his pic clearly shows the rubber hose coming straight off the Compressor output. I'll get some stainless braided line. Thanks.
I no longer have that Jeep or any of that hose left but it was special high temperature red Goodyear hose and IIRC it had a 350 degree rating. That's how I was able to connect it so closely to the compressor. The usual way of connecting to a compressor is with some kind metal hose like copper for a couple feet before using rubber hose.

I can't find any rubber hose anywhere that has a temp rating north of 275 degrees. Maybe they just don't make rubber hoses like they used to

Like compressor output, you need both numbers. Pressure x Temp. Aeroquip will run at 300 degrees at 250 psi. I still wouldn't connect it where yours is connected.I can't find any rubber hose anywhere that has a temp rating north of 275 degrees. Maybe they just don't make rubber hoses like they used to

It was probably overkill but I used Summit braided ptfe hose with their screw on ptfe fittings. It is a little stiff to work with but is rated to 400 degrees and more psi than the compressor could ever make.
Goodyear has it on their website, just search for high temperature red rubber hose. I bought mine from a Parker hydraulic hose shop.I can't find any rubber hose anywhere that has a temp rating north of 275 degrees. Maybe they just don't make rubber hoses like they used to
