Do i need a catch can? I noticed that my TA seems to spit black **** out of the exhaust a little, it leaves little marks behind the car on my driveway, my question is, is it spitting out oil or what? I'm wondering if i need a catch can or something. Its got patriot heads and a .585 lift cam.

I agree black smoke generally indicates unbrunt fuel or soot. Oil would be blue smoke.
a catch can works with the PVC system where oil is forced out of the crankcase breather and back into the throttle body. The oil would then be vaporised during combustion. But you are only talking small amounts of oil in most cases.

I think you have been mis-informed. Go to this website: http://auto.howstuffworks.com/question66.htm read the part that says "The catalyst helps to convert carbon monoxide into carbon dioxide. It converts the hydrocarbons into carbon dioxide and water"

ok water vapour is a by-product (I had to re-read the blurb on RT's website). But that doesn't mean it's fully the cats doing it as the chemicals for water (H20) were already present.
Water/steam (water vapour) are present in non catalytic cars, trust me I know as cats were not mandatory in the UK until 1993 so lots of cars don't have them. My TR7 V8 doesn't have cats but on a damp/colder morning a vast quantity of steam is present at sart up and until the engine has warmed up a bit.
I also had a V12 Jaguar without cats (sold it just before Christams last year), I removed the rear silencers on it one time and the drivers side one was full of water, this was not rain water either or from fording deep water it must have originated from the exhuast gases.
