Before you get too worried, do a pressure test on each cylinder - dry and then wet, to see if/where you are losing compression...

That will give you a better idea of where to start.

I'm not sure how pouring some fuel directly into it caused a bent push rod... Especially no just a teaspoon... Unless you had a valve sticking from other causes maybe...

Are you sure there are no intake or exhaust restrictions?

Or also - I had a rat eat a hole in the intake air hose which caused it to lose all power on the top end, since the turbo could'nt build any pressure.
