    I work for a trucking company near Portland Oregon, I'm tired of seeing dealerships charge drivers 25k to 30k for inframes and way overcharge for even small simple problems, when I was doing rebuilds id get paid about 200-300 for the hours it took, when I was ordering parts through the company, a piston and liner kit was about 2300, a crankshaft was about 2000, about 700 for a bearing kit, 200 for gaskets, 1200 for injectors, 900 for valves, springs and retainers and about 900 for a cam. so that's what like 8k something, and a couple days work, and you pay that much on top of 17k for dealership labor, #### those guys man, anyone having any problems with the engine just let me know and I can probably tell you what it is, not much experience with isx engines, mostly n14, m11, series 60, c15 and 3406

    Ok great I have a situation. I have a Pete 379 with a N14 and get a code 4-3-1 occasionally. I recently changed the position sensor and after approx 450 miles the CE light came on again. I remember reading somewhere about a electro magnetic sensor (or something) down by the clutch or flywheel that could trigger this. Do you have any info on this? Thank you.

    What does usually blue smoke out of exhaust mean? I usually get it at a start up and sometimes when idling for a while. N14 engine

    Blue smoke is unburnt Oil..
    Sounds like your Valve guides or Valve seals are worn, & letting residue Oil seep in on top of your pistons whilst your motor is sitting

    most likely the turbo seals around the intake or exhaust housing, blue is generally burnt oil, white smoke is usually coolant burning, seal kits are about $50-$100 I believe, just a couple bolts around the housing right outside of the turbine housing, takes about 2 hours if its your first time, easiest way is to take off the intake hose, unclamp the exhaust downpipe, and remove the oil and coolant lines but leave it hooked to the exhaust flange to support the weight, use a very light film of Loctite gasket sealer on the gasket and a thin coat of thread lock on the first couple threads of each bolt and tighten in a cross pattern to prevent leaks, bolt it back together, let it sit for 24 hours for the sealant to set, start it up and let it high idle for an hour before driving

    No way a n14 should be $25k or more. The ISX is $25k to inframe at dealer.

    Blue smoke is oil. I would think your engine is miled-up pretty good. If it burns clean under load it's probably a little tired. Needs higher cylinder pressures and temps for the rings to seal. On cold starts and when it idles long enough for the cylinders to cool off the rings pass a little oil.
