water ?

[Jeepers]

Getting just enough water in #1 to make the motor stumble. Is there a way to determine if manifold is bad or intake gasket leaking. I pulled distributor and there is a small amount of milkshake oil in plenum but none on dipstick, even after motor warms up. I tend to go with intake gasket. What say you ?

Nevermind. After getting into it I found a bent pushrod and a seized valve. I change my vote to exhaust manifold...
