Son was driving when rad hose blew, I drove to and replaced hose then followed him home, no smoke. Days later found head gasket leak by #1 cylinder. Small coolent leak but no oil in radiator so I thought I would try a quick fix with a product called Steelhead. While speaking to Robert who owns the company I followed his advice which was contrary to the written instructions for the product. Robert told me to add the product and drive car for 10 min at 60mph. Well she overheated and the motor locked, had to get car towed back home. I added Mystery oil to all cylinders and let the car sit. I have tendinitis in my hand now so very hard to hold onto tools. Waiting for body to heal so I can try and get it started. Wife wants it gone.
