Dealership says that I have an intake manifold gasket leak, and I want to make sure I am not being conned.

Asked by Aug 25, 2015 at 04:12 PM about the 1996 Chevrolet Lumina

Question type: Maintenance & Repair

My car is running fine with no idling or acceleration problems. But when I went in
to get my fuel pump replaced they said I need to also replace the intake manifold
gasket. There is oil in my antifreeze, but my dad believes there should also be
antifreeze in the oil, which there is not. This is on a Chevy Lumina 96 V6. Should I
hunt for a second opinion?

They probably meant Head gasket unless that intake manifold covers both intake air/water/coolant ... if there is oil in the coolant than that's irrefutable proof you have a serious problem. I would first drain the coolant fill it with water then try Barrs leaks for a couple hundred miles then when the engine is good and hot torque the head bolts .. tight. Then drain the water and replace with coolant. That worked on a couple older GM's that had the Delco coolant problems. Obviously a gasket repair is the best way to go but a19 yo car may not justify a large repair bill ... good luck
