martinf Posted November 15, 2008 Share Posted November 15, 2008 I've got a R763 with the cummins 335 in it. I haven't had this truck long, but man it smokes. Lots. WHitish gray. Huge amounts on start-up and then even after it's warmed up. It's an old logging truck with a prentice self-loader on it and I really bought it for the loader, but would like to fix the truck up. I don't know this engine well enough to know what to suspect.Also, anyone know where i can pick up an engine manual for the NTC-335 cummins? I see lots on ebay, but not for the 335. Would other NTC series be close enough that those manuals would be useful?thanks for any assistance.~martin Quote 1965 Mack B-74, dump1974 Mack R, logging w/Prentice self-loaderwww.somewhereonthemountain.blogspot.com Link to comment Share on other sites More sharing options...
