QUESTION: Ok yes I know that the best. Way is pull the motor. But seeing to it that I am a student right now I do not have those kind of tools, or the time for that.  I guess I simply need to keep doing what I do best. And that's never giving up and being hard headed. I do thank you for your input and help. Best of luck to you

Answer
your welcome, only other thing i found was that by removing the motor mounts, jacking up the engine and lowering oil pan as far as possible. the lower bearings can be removed without too much difficulty. the upper bearings can be removed by turning the engine over by hand and reinsatlled by turning the engine back over in the opposite direction
