'93 Pontiac grand am engine knocking noise?

Answer 1

my grand am had an engine knocking noise. it was the intake manifold gasket was going bad. it was leaking coolant into my oil. look at your oil to see if it is a white milky color. if it is then you need a new manifold gasket which sucks. it takes a long time to do by yourself. or you can take it to a place that charges you $1000 to do. but if you can. do it yourself
