From what Ive been reading there is some good information on the sticker on the passenger side valve cover. My sticker has been removed by someone before me. Any reason someone would take it off intentionally? There's a spot on the valve cover that says "void void void" where it was peeled off. Can I get the same info from my VIN? If this is gonna cause me a problem someday I'd prefer to address it now.

 

Engine serial number and date of build. The rest of the info is just internal stuff for Navistar.
