I got a 96 chevy one ton 6.5L. My truck pukes out tons of black smoke enough to coverr the road to where people cant see behind me. Should i be concerned about this? It runs fine and has plenty of power but just wondering if this is bad on the truck? -

I would be a little bit cause you can get a ticket for excessive smoke. As long as you get into a lot you shouldn't have a problem -

6.5s should smoke under normal circumstances. I would check to make sure that your wastegate system is working correctly first. I would also make sure that your air filter is clean and that there is no obstructions in front of the turbo or air intake. -

make sure it can freely move and there is no play in the turbo. for 6.5 who had the first question check to make sure the vaccum system is working -

How would i check the vaccum system to make sure it is working?Now it boggs down doesn't seem like it has any balls what so ever. -

it sounds like u need to buy a ford -

when it boggs down does it pour out black smoke. if theres no turbo play your probably not getting any boost and the wastegate is open. wire it shut and drive around for a bit and see if it gets any better. dont drive it like you stole it but normal street driving. look for any holes in the vaccum system or broken hoses -

My dad tried to tell me it was losing power but i drove it today i had no problems..it runs fine but it smokes more than one of my buddys cummins it pours out and i heard alot of smoke out of a 6.5 is bad.?,you can hear my turbo whistle sometimes. but it still has balls but alot of smoke....my wastegate is fine...where exactly is the vaccum and all these hoses at that you are talking about. -

well if your pouring out blacksmoke i can tell you are losing power. 6.5s cant flow enough fuel to be pouring out black smoke and have the turbo working. the hose going from the wastegate to the front of the engine should be checked. the vaccum pump is in the iddle of the serpintine belt on the bottom. most likely it is not working. -

Fore go the ford and just get a cummins and put it in your chevy or buy a dodge. -
