1993 Buick Regal Question: DOES OIL LEAK
Answer #1patrick mannion from Greg Solow's Engine Room, July 07, 2011, 21:32Master
I think I answered this question earlier. An intake manifold gasket may leak coolant or may cause a drivability issue if the intake gasket does not seal properly as it may cause a vacuum leak.

Yes, it can leak coolant, vacuum and oil.
