Question

Visitor, 3.4L V6, Phoenix, AZ, January 05, 2011, 16:17

I had just replaced the radiator, there was a leak and car was over heating. My engine is making a knocking noise, smoke from the back of the engine (cat. Converter) white smoke from the exhaust and funny sweet smell.

    you have a blown head gasket resulting from the overheating.

    major repair. estimate about 1500-1800

    unfortunatly that sounds like a typical blown head gasket, usually caused by extreme overheat. Be sure to have the heads checked for cracks and warp
