theres a hose that runs along the bottom of the head, intake mani that i think goes into it. and runs to the back of the block by the firewall?? if i member correctly. i think thats the one hes talking about. its kinda small. theres also a hose (on my b2000 but not on my 2200) that also runs into the block directly above the oil filter. i had problems with this hose. if u stick your head up under the passenger side of the truck, look up under the intake u can see all those hoses so u might could clean them all off a little and run ur truck to running temp and see if anythings leaking.
