[chuy]

Hey guys new member here... I was hoping to learn a lot more and make it out to one of you guys for overhaul BUT my truck just used(mostly spilled) 15 gallons of oil this past week and it’s time! It went from 2-3 gallons a week to 15gallons last week! 2007 KW T600 780k on CM870 CPL 8520 450hp. Any pointers would be greatly appreciated thanks guys! I just received inline6 and pyro/boost gauge and was ready to finally get my head outta my ass and this happens. I’m to blame of course but I can sure use some help if you can lend some guidance. Funds are limited. I’m in northern Illinois/Wisconsin birder off I-94. Once again any help is appreciated.
