i have a 95 mc Z34. i had a problem with it leaking anti freeze and it was the intake manifold. i got that done, but now the car has a knocking noise could that be my valves or lifter or something else. i really have to fix this problem for me to go to work. or a diagrams to take this car apart. thanks and maybe somebody can help me

 

how's the oil level after the work?

 

Is it a deep knocking or a tapping sound? If its a tapping sound its probably the lifters. If its real bad they may need replaced, but if its light and goes away after a few seconds you are probably ok.

 

Mrl390's advice sounds good.
