Blown head gasket? Read this before you pay for a replacement
The verdict on your engine can be reversed.
A mechanic said blown head gasket and quoted more than the car is worth. Since 1995 the people who invented chemical head gasket repair have been putting those engines back on the road. Sixty seconds tells you if yours is one of them.

What a shop charges to replace a head gasket, when it will do the job at all. Most say replace the engine.
"At 190,000 miles you're not going to put $7,000 into a head gasket. A Toyota can go 300, 400,000 miles, and we can fix a Toyota in 15 or 20 minutes."Dave Whitmer, 1,100+ field repairs
"Thousands of cars are lost every year simply because people poured a pour and go product in there. There is no product capable of fixing your car that is compatible with antifreeze."Robert Hooper, chemist, inventor of Thermalweld

Six months and 2,900 miles later the car is still going strong. Saved a $4,000 repair.
It's six years now and the car is running beautiful, no problems with head gaskets leaking.
Fixed it right up. Stopped misfiring and shaking immediately and no more white smoke.
A local mechanic said the car was doomed. I ordered the Northstar kit, followed Robert and Dave's instructions, and the car is running again.
I tried K-Seal and Titan sealer, both didn't work. Drove about 1,000 miles and the water level did not change. Did not clog the heater core.
After 16,000 miles, still running great, no overheating. My daughter's car blew its head gasket two weeks ago. I'm glad I kept his number.
I was stuck, couldn't afford any of them. Dave came to me, charged $425 and had my car humming. No misfiring and no exhaust smoke.
I run an auto repair shop. I offer this option when the mileage is very high or replacement is too expensive. All of the vehicles are still on the road.

Robert Hooper
Formulated Thermalweld in 1995 and created the category of chemical head gasket repair. Thirty one years later he is still the scientist behind the formula, still improving it, and still on the support line. Twenty of those years were spent in the field doing the repairs himself.
Dave Whitmer
Runs Ideal Head Gasket Repair, a mobile service covering Los Angeles, the San Fernando Valley, Ventura, Santa Barbara and San Luis Obispo counties. $450 in your driveway, most vehicles, in about an hour. If the repair does not hold you pay only the $125 service call.
Before you pour anything
Understand your cooling system first.
Most head gaskets blow because something else failed: a stuck thermostat, a weak water pump, a clogged radiator, a fan that comes on late. Fix that too, or you fix the gasket twice.
Sixty seconds. Then you know.
Answer seven questions about your engine. You get one of three answers: this is your kit, call us first, or don't buy this.
