is it possible that the z would sputter then die if the rocker arms were not tightened down to specs..wouldnt this mean that the valves are not lifting enough and for some reason the car wont stay on if you get to like 3000 rpm while driving.cause idling the car stays on if reved up to 3000 rpm..i just dont know what can be causing my car to do this..and i have a dumb question also, is the alternator suppose to get hot??

well turns out one of the valves is staying open according to a friend of mine.i was gonna try and fix that when i took off the valve cover and noticed this creamy gooie lookin stuff in the top ..i said this cant be good..i showed my friend and he said my head gasket is leaking..it was oil and water .i just freaking did that job!!!!!!!now i gotta do it all again...f*ck! what do you guys think is this most likely the problem??

 

If the gaskets are in deed leaking, the likely problem is a bad valve guide causing the valve to stick. When you did the gaskets before, did you check the heads for flatness?

 

the heads are brand new
