Question about 1998 Nissan Altima
My car shut down on me on the interstate one night there was no sounds at all coming from the car and I was told that the alternator may be bad. It was tested and found to be bad and had also killed a couple cells in my battery, which also had to be replaced. After repairs, the car developed this loud knocking sound in the engine. And plumes of white smoke and exhaust poured from the tailpipe. Has the car thrown a rod? And if so, what are my least pricey options for repairs?

It sounds normal white smoke comes from moisture in the air as it's burned and the air temprature is different. it creates steam they gray smoke is a little harder to decide what it is, normally gray smoke is related to oil burning and black is over fuel, depending on how many miles it has on it it could have bad valve guide seals but would not worry about it.

Don't rebuild that engine. Replace the head gasket. machining the head is not necessary. Clean both surfaces with fine emery cloth.
