Intake Manifold Gasket Appears OK

Coolant going into crankcase. Does that prove it is the intake gasket leaking?

That is the most LIKLEY reason for coolant in the crankcase. Worst case would be a cracked block.

Hi, I am having big problems in trying to make this truck run. I have found top dead center as best I could. It starts after I mess with the timing, but it revs up really fast for about 3 or 4 seconds and then stops. Did I miss TDC?
