Need advice on what to do with my motor

[kinknoppix]

The problem with my engine now that i have-- I can not rev above 2500 rpm. Terrible knocking sound or something definetly hitting something in side. It will start and idle fine..What happened was i ran it across a dam to see my MPH and after i was through i notice power loss and noise but i did make it home safely. There is no water in my oil nor do i see a oil leak....Where i live i can not take out the engine unless i get a storage place and i thought maybe getting a used motor and just droping it in will be less hassel. Maybe i can fix the problem, I do have the book"how to rebuild your nissan and datsun". Should i take it to a room and try to open it up myself and fix it? I dont have much tool but i do have a lift. I have dont little work on my car as far as replacing the cluch assisted an engine swap. I believe i can do a swap but i dont know about fixing something inside. What do you think?

If you have the book, you have a head start on me, and I'm puttering through a V8 rebuild

 

read the book cover to cover, then read it again, then open the engine up and dig in take lots of photos so you can see how what bits fit where. Don't forget you can post them on here when you stuff up so we can laugh and then tell you how to correct it a good swap, entertainment for education, and then if someone else stuffs up, the solution is in the search.

You say you went over a dam? Did your car get wet? Did you go through any large puddles? If so, your TVS/TPS could have gotten wet - this would cause the problem you are having. Very common for people who power wash their motors, without realizing how sensitive some parts are to water.
