    check your pcv, and make sure the port for the pcv at the tbi isn't plugged

    Remove the oil fill cap and start the engine. If you feel air blowing out of the valve cover, then you have a serious blowby problem. The only fix for that is a rebuild. :(

    Blowby is combustion pressure getting past the rings and down into the crankcase. Not a good thing. :(

    Were the cylinders just honed, or bored and then honed? I've seen a lot of rebuilds where the tapered, out-of-round bores were ball honed, a new set of rings thrown in, and they run it. The result is predictable - poor compression and lots of blowby :doah:. Ball hone rebuilds only work if the motor is low-mileage and has no taper or out-of roundness in the cylinder. Anyway, it sounds like a lot of blowby to me as well. Even if the PCV is plugged a healthy motor shouldn't spew that much oil or smoke from the breather tube...

    I think that "rebuilt" motors are much more likely to have blow-by issues than stock motors with high mileage. There are tons of people that either do half assed rebuilds or have actually never rebuilt it and claim that it has had a rebuild.

    Check the PCV system first, though. It's easy enough to check (and fix).

    Could be worse...You could have had a motor built, then added performance heads, cam, and intake, installed by a friend that "knew" what he is doing, and less than 3k miles later have a blown head gasket because the friend didnt torque the heads right and used RTV on the head gasket. Oh yeah, it blew a couple days before I moved over 1000 miles. :doah:

    Did you at least get a warranty or did you do it all yourself? If you dont have a warranty, have your next motor built by a good shop that will give you a warranty and go bigger.:pimp:

    well the part that sucks the most is i was fixing to sell the truck as much as i dont want to... and im broke and cant afford the rebuild. all i really need to do is go back in have the block bored and put in new pistons and rings everything else is new.

    Measure the bores (or have them measured) before you go dropping coin on new parts. It might be something simple (and dumb) like all the ring gaps lined up or something.

    Do a compression check before you tear it apart and see what the numbers look like.

    Always start with the simple things first.

    And still check out your PCV system.
