Blue Smoke - catch can?
Im getting blue smoke out of my exhaust after hard acceleration...I think I may have messed up during emissions removal. Is this the nipple I am supposed to hook my catch can up to? I capped it like it is in this picture, but is it supposed to be vented?
Im assuming its not an oil seal because it doesnt smoke after i hold it at 4000 rpm for 15 seconds...only after hard acceleration...i think its just because pressure is being created in the oil pan...from my emissions removal...or so i hope.

Don't both nipples still lead to the "crankcase"? If so then it should not matter which line you run to the catch can. For example in my car I have the lower one leading to the purge valve and the top going to the charcoal canister (as it is stock).

get a catch can, you can get one off ebay for about $30.
tee the line to the catch can from both crankcase vents(one off the filler and one off the middle iron) and run the line into the catch can. mount the catch can as close to the engine as possible without letting the hoses hang for oil to accumulate and block flow. mount the can with the base of the can near the top level of the engine so gravity will not be working against the system. run the second line off the catch can to the ground and check to make sure the can is not full periodically, also check your oil levels often to be sure you are not losing much oil to the can.

the charcoal canister will get gummed up, may as well save it for emissions testing if you need it in the future.
Aaron's setup varies from yours, if you want to run the charcoal canister then you will need to hook up a crankcase "pull" to your intake pipe like it is setup stock to draw crankcase vapors into the intake, the charcoal canister is pulling vapors into the intake also through the purge system but if it is vented to the atmosphere then it will collect oil.
