Ive had these installed for a while now however i think it should be important for any LS4 owner to put one on.after two months it trapped almost a 1/3 cup of oil. not bad for a el cheapo catch can from ebay.
link for the catch can http://www.ebay.com/itm/UNIVERSAL-HI...40bb05&vxp=mtr
install is simple i used 3/8' fuel line i had lying around to connect to nipple on valve cover and the same for the nipple on the intake manifold
Install wherever you want in the engine bay however i try to keep mine away from exhaust componets or other high heat componets.
update*** did follow up video click the link.... install pics are below

Pics are self explanatory. and if you need the refrence the fitting on left of the can is for "dirty" air and centered fitting is for clean air. drain plug is on bottom.
