Can I still drive a car with a head-gasket leak?

Question

I have a 2002 Pontiac Grand Am. First mechanic says I have a cracked head OR head-gasket leak. Engine builds pressure over longer drives at higher RPM's and eventually blows coolant out the relief-cap. Tests show hydrocarbons (exhaust) in the coolant. Can I still drive this car 13 miles to work (and same home) until I can get the $$ to get it fixed? Or will this ruin the engine? Car runs good at this distance. Repairs are estimated at $2500. Thanks All!

Answer 1

Leaks are never good and should always be fixed asap.

Answer 2

Grand Ams were better known for intake mani gasket leaks, at least with the v6.

In that case, coolant mixing with oil turns that oil into glorified water.  That's definitely not a good lubtricant.

Drive at your own risk.

$2500 is way too much.  Grab a junkyard engine and get the gaskets changed on that and then put in the car.

Answer 3

I wouldn't. If you continue to operate this vehicle, there's a great chance that you could blow your head gasket completely, which creates a greater risk of damage to other components of your car. The last thing you want is to be driving down the highway, and suddenly have a total loss of coolant pressure, brake failure, engine fire, and loss of power steering due to a blown engine. Not only would the cost of repairs skyrocket, but there's a huge risk of injury to yourself and others, and damage to your vehicle.

I would at least have the head gasket replaced. Price out costs at different shops first to ensure you're getting the best deal.

Edit: Exhaust in the coolant means coolant in the exhaust. If your engine is burning coolant, then there is a great risk of damage to your spark plugs, valves, and injectors.
