1993 Buick Regal Question: MY CAR IS LEAKING OIL

It sounds obvious the valve cover gaskets are leaking, the intake can leak intake manifold vacuum or coolant but not oil. It may be necessary to wash down the engine and or add dye to the engine oil to pinpoint the source of the leak but it is common for the valve cover gaskets to be the source of the leak you describe. Get a second opinion.

Oh a buick Regal, You either got the 3.1l 3.3l or 3.8l (very rare for 3.8l). They are very common to leak from the intake manifold gaskets where the push rod goes through to the cylinder head. The valve cover gaskets are common as well as if your model don't use the distributor, it now have a driver gear for the oil pump and that leaks all the time with age. But it's just an o'ring there. The best thing to do is bring in for an inspection.
