    Hello, i have a single axle dump with a 3126 engine in it. It has blow by coming out of the tube but the engine runs great. We only use it around town and i would hate to have to put another engine in it. Can i run the the blow by tube in to the intake or something else like a modern diesel?? It just smokes a little to much on the job site to use. Any input or help would be great. Thanks in advance

    cops will eventually start pulling you over to fix the problem. it's what happened to me.

    what i did was run a pvc to the back of the truck so i didn't have to breathe it to much.

    diesel engines don't get replaced. they get rebuilt. you'll get a piston kit which runs $2g. it contains pistons. rings. rods, bearings, and cylinder sleeves. how much the labor is i couldn't tell you.

    i had the same problem on a single axle drop dump truck. the top piston ring on all 6 was broke. winter time came. truck got parked and torn down. company truck.

    don't know what engine that was. but it was found that cat installs undersized pistons.

    somehow. i don't think motors were shipped from the factory smoking like a freight train. so yeah, the cops CAN make you fix the problem. it's called polution. specially when the cops think your truck is on fire.

    in utah. you can get your vehicle impounded and plates revoked for polluting the atmosphere. specially when it's so bad that cars literally disappear in the smoke. your creating a hazardous condition.

    As long as it doesnt gum up your turbo. Hey, what the hell, try it and see. Its that or get an old oil bath air filter and mount it for the blow by tube to go through.
