also we werent sure how to hook the oil catch can up. it seems to b a knock off greddy old style. it has 2 nipples on the top and one on the bottom and it came with the block. on the back of the block the huge bolts on either side of the oil filter have nipples so we are running the two top to each nipple and then the bottom one goes to the IM. Ive run thru the net but no such setup like this.
