ok new problem now....on top of EVERYTHING else now ive noticed when i start my truck for the first time, my oil pressure gauge takes like 5 seconds to get to normal range, what could it be? its not the gauge because i can hear a "tick tick tick" untill it gets to normal range. did an oil change with full synthetic and fram high milage filter, and its still there, but only on inital start up and like when i come home from work, so basicly if the truck sits for hours itll do it, but not if the oils warm, like when i run errands or whatnot. oils full, not leaking, is my oil pump on its way out? please check my profile for all problems i have, none of which seem to interfear with this one, unless its the mysterious belt squeeking at idle when its warm out, but it dosent squeek during accelerating or if its cold....help please, and once again THANK YOU EVERYONE FOR YOUR SMARTS
