Re: STILL CLUELESS....Still WALKIN Fellas....Help!...
If you let out the clutch in 2nd gear at 90 MPH, then you have a serious over-rev condition. This means the valves "float" or stay open instead of following the cam lobes. When a valve stays open when it shouldn't be, the piston comes up and hits it, bending the valve. A bent valve won't seal any more, so you don't get any compression when you turn the engine over. You can run a simple compression test to confirm. As I said before: probably bent valves in every cylinder. If confirmed, then probably the cheapest way out is to find a used cylinder head assembly, or maybe a complete used engine.
