I am looking at an 02 Dually with a 108k on the clock. I live 20 miles from the dealer, I test drove it to my house and it ran great but when I was stopped I could smell fuel strong, like degreaser. I got under it and there was fuel everywhere on the crossmember, trans pan and blown back. It looks like it is coming out of a blowby tube on the bottom passenger side. I did check the oil level and the crankcase is full or fuel. I checked the VIN at the local Chevy dealer, and it has a clean bill of health. I am wondering if it is likely just injectors or if it could be more serious. The coolant levels are fine and it runs strong, just hoping that maybe the injectors are cracked and dumping too much fuel. I did use the search feature and have read alot of the posts, but none really mention blowing the excess fuel/thinned oil out and under the truck. I haven't bought this thing yet, and if it is just injectors I am cool with fixing it ( I am getting a very reasonable deal on it). Thanks
Doug
