Default Found the cause of Crankshaft Position Sensor problem....

you'll recall the engine would not rev over 4K and I was getting the P1579 code after installing new (used) engine. I got in the garage this weekend and removed the tranny and here is what I discovered. The head on one of the small bolts that holds the friction surface to the flywheel had broke off. The bolt was then bouncing around inside the bellhousing and bent one of the shutter wheel teeth. That is the tooth that was hitting the CPS.:

You can see some scaring on the flywheel where the bolt was hitting the bolt holes. It sucks to have to do this all over again, but Aasco has been very easy to work with has a new unit on the way. If something happens 1 out of 100,000 times, gotta figure it'll happen to me! Don't come near me during a thunderstorm!
