I got a 1998 dodge ram 2500 that i use as a mud truck but since i have owned it , it has smoked like crazy, im going through more oil than gas and that is not an overstatement, about 3 quarts a week sometimes more. my question is what is it. i replaced the plenum and it didnt effect it at all. i installed the hughes plenum plate. i dont know if it blew again or not but the truck still makes good power just smokes like mad. any input is greatly appreciated.
