is this oil? pic inside..

Was that before or after you refilled it? It could just be nasty old rusty coolant...

I'd flush it a few times, and see if its still brown.

Nah, don't think you will ruin anything. Depending on how cold it it where you are, and what your thermostat is running at, water may never circulate if you just have your car running in the driveway. On the otherhand, the tstat may be stuck, and if you are extra paranoid like me, I would nip a potential problem in the bud and change the tstat.

Also, unless you take out the thermostat and THEN flush the radiator and block, that crappy brown stuff is pretty hard to flush out, IMO.

"also i havnt been able to get athe upper hose to build up much pressure i can collapse it with my hand"

It really doesn't look like oil in your coolant, but it looks like dirty coolant to me.

How long did you run the car, when the thermostat is closed, the upper hose will collapse. Once the T-stat opens, the upper hose will be hard. It can take up to 10 minutes for the T-stat to open if it is cold out.

When you have oil in the coolant it is not only brown, but it is slimy, kinda of like a milk shake. If the coolant is not slimy it is probably just crud out of your cooling system. Flush it again with some stuff from the parts store, drain it and add a 50/50 coolant water mix to it. Run it and see where you are at. Also if you are losing coolant into your oil, your oil will look different, check your dipstick and see where you are at.

I wouldn't drive it till I knew what was up with it. If you have coolant in your oil you can easily wipe your bearings.

Finally from swapping your intake, you are not going to get oil into your coolant, you are going to get coolant into your oil. This is because there is no oil running through your intake. But there is coolant running through your intake, so it would leak out your water jackets from the intake and drop into the cylinders putting coolant into your oil.

so the only way to check the oil is drain it, if i just drained a little bit from the bottom would that be sine enough or does the water float on the oil? or is it the other way around?

I also tend to think you just have rusty crap in your water, not oil. So you know if you drain some oil, water is denser than engine oil so it will sink to the bottom of your pan. Likewise, if there is oil in your coolant, the oil will float to the top and leave a greasy film.

And get a dipstick homey.

word to the dipstick but how do you get them in there.

so in theory the water would come out before the oil if i crack open the drain plug.

You could take a torch and carefully bend the tube until it clears. Dont do any crazy shapes or anything because the more twists it has the less accurate it will be.

Not in theory, in reality. The only exception is if the oil and water are whipped up into the aforementioned milkshake. If there is a problem, you'll either get water before oil or just gray muck. Most likely you'll get nice amber oil, though.
