Car will not start

  • 2.0L
  • 4 CYL
  • 80,000 MILES
I was driving down the road and the engine started a tapping sound. It got louder when I pushed on the gas. At a store, my brother checked the oil and said it needed a quart and he put one in. It started up and seemed to make less noise except when I was in idle. Then going home the noise came back louder and suddenly the car stalled and I pulled off the road. Some smoke came out of the hood but the water temperature light was not on. I could not start the car again and had it towed home. My husband checked it and it needed water which he put in about a full ice tea pitcher of water. It still will not turn over. I am pretty broke and can't afford to have Hyundai check it for $105.00 per hour. If you could help with an idea, I'd appreciate it very much. Thank you.
Do you
have the same problem?

Sorry, but this sounds like a blown head gasket. Remove the spark plugs and have someone watch the plug holes. Will it turn over then and is there any water coming out of the holes? Start here and come back.

It will not turn over, and yes, there is water coming out of the holes.

If you have coolant coming from the spark plug holes, there is either a blown head gasket or a crack in the cylinder head or the engine block. Here is what I suggest first: Take a look through this link and see if it applies to what you are seeing:


Now, based on your description, I am nearly certain the head gasket is bad. If you determine that is the problem, here are the directions for removal and replacement of the cylinder head. I do recommend having it inspected for cracks or damage while it is off.

The attached pictures correlate with the directions.

Vehicle Engine, Cooling and Exhaust Engine Cylinder Head Assembly Service and Repair Procedures Removal

Engine removal is not required for this procedure.

Use fender covers to avoid damaging painted surfaces.
To avoid damaging the cylinder head, wait until the engine coolant temperature drops below normal temperature before removing it.
When handling a metal gasket, take care not to fold the gasket or damage the contact surface of the gasket.
To avoid damage, unplug the wiring connectors carefully while holding the connector portion.

Mark all wiring and hoses to avoid misconnection.
Inspect the timing belt before removing the cylinder head.
Turn the crankshaft pulley so that the No. 1 piston is at top dead center.
