2001 Chevy 2500hd 2wd lb7 duramax/allison. 256k miles. ZERO blowby. Has a bunch of work done to it. 64mm turbo, 45% over SAC style injectors, headgaskets/headstuds, airdog 165 lift pump, edge cts3 monitor, performance valvebody with a dans diesel tuned tcm, HSP traction bars, PPEI sotf tunes with a high idle tune (#2). It is detuned since it has the factory trans but you could get another 150+ hp out of it with a built trans. Entire front end was just rebuilt along with new rims and tires. Also has a new alternator, brake booster/master cylinder and water pump. Only "issues" is it has a check engine light for a glow plug relay but they still work just fine. It'll fire up no problem in freezing weather. The water in fuel light also flashes since the factory fuel filter/water separator is deleted since its got an airdog lift pump. The truck runs and drives like a dream. Also has double din head unit with a backup camera. Probably missed some stuff. Solid truck. Clean title in hand.
