I recently took my car to jiffy lube for an oil change, and they said they found sludge in my oil, they said it could possibly be a head gasket. My car seems to be driving fine, stutters every now and then, and when in idle seems louder than usual. I dont see any smoke come out, unless i just start my car, and my car does not overheat. What may be the possibilities of whats wrong with my car?

Sludge is oil that has been left in crankcase too long and over time heat will cause oil to sludge.

I would drain and flush cooling system and if problem persists, have compression test performed to check headgasket and cooling system pressure test to check intake manifold gasket.
