well as the title says im missing a couple vaccum hoses it appears... rough idle, kinda struggles when i get on the gas a bit. i remember running into the 2 hoses last time i changed the tstat housing. but since then i had to send my truck to a mechanic and eventually had him drop a new engine into it. now aside all the idle issues and all that it runs great. all the symptons pointed towards a pcv valve but as i was looking i have the hose that runs to the back of the valve cover on the driver side. but im missing the 2 on either side of it. if i just knew where they were supposed to go to from there id get them put back on.. but i have no idea and i dont like running it the way its going. any and every bit of information is appreciated. pics would be wonderful. thanks in advance!

May be it will jog the memory
