Chevy Lumina roughly 1994 Lower Gasket antifreeze leak?
I'm a little confused.
My friend has a Chevy Lumina and it's running a bit erratically and is sucking down coolant by the gallon. She brought it to an auto shop and the guy started doing an oil change and said a lot of coolant is in the oil and that the lower engine gasket is show and if she wants her car fixed then she needs a new engine. She had the head gasket replaced last year, and it started acting up a few months later and she parked it until spring.
I've never run into a lower engine gasket, but I see them available for purchase. I can't find any instructions or anyone online talking about them which seems odd. Do they exist, are they called something else? Also, is it possible this is the head gasket leaking again? When the car is running about 1 gallon of coolant leaks per 20 minutes of driving. The mechanic didn't do any disassembly but said he only seeks coolant in the lower engine oil and not the upper and I have no idea how he's making that statement. Seems a bit off to me, but I'm somewhat new to this game.
