i am going to be replacing the intake manifold gasket that causing a vacuum leak,
a friend of mine said i need to be carefull when removing the intake manifold because it will have coolant in it that can spill/ leak into the valves below,
the haynes repair manual i have does not mention this ,
can you advise if this is the case?

it may not have it like the older ones did. but you have to drain the coolant and not a lot of coolant will get into engine anyhow but you are going to change oil and filter as well so it really shouldn't matter.
