  1. If the crank is really moving that much and the crankshaft journals are rubbing (wearing) on bare steel (once the top layer of bearing is worn through) the crankshaft is likely toast as no-one has oversize bearings or thrust washers. A used crankshaft might set you back $2-3k. If the damage is beyond the crankshaft in the bearing carrier, you are looking at another couple grand.

    Complete engine tear down and rebuild (even without replacing bad parts) will set you back in the $14-18k range when done properly from a reputable source.

    So... unless you are into rebuilding engines, you are likely better off sourcing a used engine. It looks like you have a line on one over on rennlist which sounds like an excellent buy from a reputable source.

    Also, a few words on driving it until it blows up.

    1.) It might be possible there could be collateral damage and the expense could be even greater replacing it after it blows up.

    2.) Would you really want to be driving a time bomb knowing you might be stranded somewhere?

    Yep, that the way I see it.... the engine is toast already, regardless if I try to rebuild it (which is more than just dropping in a replacement).

    I think it will likely be ok until I drop in the new engine. I can't imagine it grenading itself any more than an IMSB failure.

  2. I was afraid of this... I am just going to reassemble and drive it until completely fails, seeing how the prognosis is so dire for the engine anyway. Whats the worst that can happen? The engine fails. I am SOL anyway I slice it. The only good news here is that I know that my engine is failing so I have time to prepared for it eminent failure.

    This will give me time to get my hands on a replacement engine to drop in.

    You know what is really strange is, the engine is performing strong and there are no signs of anything in the oil (shavings from the failing bearing, etc.), This is incredibly bizarre.

  3. I cannot seem to find this issue occurring anyplace else in searches- The crankshaft in my 2001 C4 cab has quite a bit of horizontal play. I can see it move about a 16th of an inch inside the bell housing when pressing on the flywheel. This is causing a bit of a problem with my crank positioning sensor on deceleration (the engine dies when I step on the clutch). Decided to drop the tranny to check clutch and change my IMSB and RMS.

    To much back and forth play in the crankshaft is giving me the creeps.... can that be repaired without a complete rebuild or engine replacement?
